Scientific literature on how marijuana works on the body is rapidly expanding. Right now, there are a plethora of studies on how marijuana works on the human brain. Some studies have shown that it can be effective in treating disorders of the brain like epilepsy. Recent tests show that marijuana can increase the risk of dementia because it restricts the flow of blood to the brain. These brain areas are essential for memory development. The area most affected is the hippocampus which can result in Alzheimer’s if prolonged. The researchers for the study used single photo emission computed tomography (SPECT) to measure blood flow to the brain after taking marijuana and they reported that there were very low and abnormal blood flow levels observed. This is when compared with persons who did not take marijuana. 982 patients were selected from a wide variety of data sources that was available to the researchers concerning persons who previously used or were still using marijuana. The results of the study showed that persons taking marijuana were at a risk of dementia due to the low blood flow to their hippocampus. Key Takeaways:
"Users were analyzed using a brain SPECT and by conducting mental concentration tests against a sample of 100 people who had not used marijuana to determine whether there were significant differences that arose between users and non-users of cannabis."

As smartphones and computers permeate the world the effect they're having on teenagers grows. Studies found that young adults who spend more than two hours talking on a phone or playing video games will have less sleep than those who do not. They also report that they are sleepier during the day than those who play or talk less than two hours each day. Alternatively, these problems do not affect those who watch TV for the same amount of time. The lack of sleep some are getting can increase the risk of depression, attention problems, and cause weight gain. Key Takeaways:

Date:
May 19, 2011 01:52 PM
Holy Basil And Pain Management.Holy basil extract is an herbal remedy that originated from India. It is best known as an adaptogen, and as such has become an increasingly popular herbal supplement in the past few years. It is effective in the management of stress, and anecdotal evidence is very positive. More importantly, recent studies have compared its analgesic properties to commonly used pain relievers in the market. Pain Perception Many different factors are involved in the perception of pain, but most painful conditions are tied to the process of inflammation. Pain is in fact a mechanism of the human body in response to situations that are potentially harmful or even life-threatening. For example, signals are sent to the brain from the body part exposed to extreme temperatures, allowing us to move away from the harmful stimulus. Pain is of course an undesirable condition, though it is helpful in certain situations. The thought of pain alone brings about disagreeable feelings, such as fear. No wonder people are always seeking for remedies for physical pain, which can be caused by open wounds or physical trauma. More often than not, it is linked to routine activities, such as bad sleeping positions and sitting for long periods of time. Common Factors Modern lifestyle renders the human body more susceptible to pain, brought on by injuries and wounds as well as physical inactivity. There are countless working conditions that doctors and medical professionals have pointed out to be real occupational hazards. We often do not care so much about the way we work because the repercussions are not immediately felt, not while we are young. Two major factors lead to chronic pain later in life: wear and tear of tissues and limited physical exertion. We become increasingly sensitive to pain as we age. We keep a wrong position during sleep sometimes, and the next morning we feel all sorts of muscle pain, such as neck pain. Similar pains take place every time we lean into our computer at work. In general, these kinds of pain are due to poor posture, which can easily be remedied. However, this can take a turn for the worse in the next couple of years as we continually subject our body to muscle strain and physical immobility. Inflammatory Mediators This is when natural remedies can help us. Holy basil has an age-old association with the relief of pain due to muscle strain. The chemical compounds that occur naturally in the plant species Ocimum tenuiflorum have been discovered to interact with mediators of inflammation. Researchers have learned that holy basil extracts are not only relieves pain but also contributes to holistic health. More importantly, holy basil extracts appear to inhibit an enzyme called COX-2, which facilitates the biosynthesis of pain chemicals. Its role is to get our attention and tell us that there is something wrong with our body. This enzyme is responsible for the sensitizing arthritic joints to pain. It is also implicated in severe headaches, migraine attacks, muscle cramps, and related symptoms. If you experience chronic pain, give holy basil a try!

Date:
February 02, 2011 10:06 PM
Night blindness is very common nowadays. According to statistics, a lack of vitamin A is the primary cause of night blindness or inability to see at night or in dim light. The treatment of this eye condition will depend upon the cause. Treatment may be as simple as getting a new eye glasses prescription. But invasive procedures may also be required most especially those that are caused by cataracts. Fortunately, Bilberry extracts may help night blindness. Bilberry is a low – growing perrenial shrub growing approximately 15 to 20 inches in height. It is a member of the family Ericaceae in the genus Vaccinium. Its branches are green with sharp edges. It bears edible berr that is seemingly wrinkled and black. Bilberry is a comparative to the common berries known as blueberry and cranberry. The active compounds in bilberry fruit are known as anthocyanosides. Bilberry extract has a deep bluish purple tone which contains the majority of the active substance of the fruit known as anthocyanidin. Anthocyanidin is a component of anthocyanosides. It can help increase the formation of rhodopsin. According to studies, rhodopsin is formed from an aldehyde form of vitamin A called retinaldehyde, or retinal as commonly used. It is then bound to the protein opsin. This compound consisting of retinal and opsin is stored in photoreceptors of the retina of the eye known as rods and cones. Rhodopsin is the compound in the eye that is responsible for adjusting eye perception to light variations. This plant extract is also commonly used for treating eye problems like cataracts and retinal disorders particularly retinopathy. Scientists found out that anthocyanosides help protect the retina. Since bilberry improves the formation of rhodopsin, adequate levels of rhodopsin can significantly improve night vision and reduce visual fatigue. This eye pigment could help those individuals who are having trouble driving at night because of its rhodopsin regenerating property. Aside from supporting a healthy eye function, bilberry has many other health benefits. It has an antioxidant, anti – inflammatory, collagen stabilizing and vasoprotective properties. Generally, anthocyanosides are considerably beneficial to the overall health of the body. It can improve circulation by preventing blood clumping by reducing platelet aggregation. It can also prevent or reduce the amount and extent of damage to cells caused by free radicals. Further clinical studies are being done to be able to get concrete evidence on the fruit’s benefits especially to the eyes. Preliminary results show that bilberry decreases eyestrain after an excessive use of computers, protects against glaucoma by improving blood vessel integrity in the eyes, reduces the occurrence of cataracts by maintaining the integrity of connective tissues in the eyes and lessens the risk of retinopathy among diabetic patients. Preparations of bilberry extracts include teas, capsules or tablets.

Date:
June 26, 2007 01:51 PM
It probably doesn’t come as much of a shock that the market for organic produce is growing—estimated by various sources at about 20 percent a year. What may be surprising is that the organic food market, which generated about $13.8 billion last year, represents only about 2.5 percent of the total U.S. food consumption. While those of us involved in the natural products industry or natural healthcare take for granted the advantages of organic products over “traditional” ones, there is a pressing need to mobilize resources in order to meet the consumer demand for pesticide-free foods. Currently, only 0.2 percent of the U.S. farmland is organic. The other 99.8 percent produces food utilizing the high-production, low-nutrient and flavor lacking industrial chemical methods we grew up with—the same tradition that drove consumers to seek out organic produce in the first place. The picture isn’t any better in Canada, according to the Canadian Organic Growers Association, where only 1 percent of the food grown there is organic. This of course raises the question as to how we are going to satisfy this increasing consumer demand. In a word: imports. We already import more than 10 percent of the organic food we eat. But perhaps the figure of greater interest is that we consume 42 percent of the worldwide organic food supply, leaving only 58% for world’s non-U.S. residents. In this enlightened era in which we understand the downside of processed foods, chemical residue and the portent of global warming, it’s hard to understand why we don’t muster our great resources and legendary spirit to launch a program to address these issues—like JFK’s Apollo Project, which put a man on the moon in under a decade using computers less powerful than are commonly found on our desktops today. While we ponder the question, there are people of good will and strong conviction who are working, albeit with limited resources, to do something about it. one group is working on remineralizing the earth. We are proud to be supporters and friends and we think you will find their concept as exciting as we do. -Peter Gillham – editor.

Date:
June 25, 2005 07:49 PM
All Calories Are Not Created Equal When we eat more than our daily energy requirements (and most of us do), the extra energy is stored as fat. The human body is designed to stockpile fat very easily. This tendency is related to innate mechanisms intended to protect us against starvation or the threat of a diminished food supply. Fat cells provide extra fuel which can be utilized if necessary to sustain life. Those survival fat pounds settle on the hips, waist, thighs, upper arms and back, not to mention around organs, like the heart and kidney. Some ethnic groups, whose ancestors repeatedly suffered from famines, are especially efficient in energy storage. These include the Pima tribe48 in the United States, the Aborigines of Australia,49 and many of those of African descent.41 Fats are very readily converted to pounds. Carbohydrates and proteins require more complicated digestive processes to convert and store their energy than fat does. Calories from carbohydrates and proteins are usually burned and thrown off as heat (thermogenesis). Naturally, overeating proteins and carbohydrates can result in weight gain, however the body has to work harder to convert these nutrients to fat stores. It takes 20 to 25 percent of the energy in carbohydrate and protein to convert them into body fat. It only takes about 5 percent of the energy content of dietary fat to store it as body fat. Fat is also twice as energy dense (9 calories per gram) as carbohydrates or proteins (4 calories per gram) making fat at least twice as dangerous from a weight gain standpoint.50 Blood taken from an individual soon after they have eaten a double cheeseburger, french fries and a thick milk shake will often be a milky pink color due to the infusion of fat from the digestive system. This fat circulates throughout the system until it is either burned or stored. A Winning Combination Most people would agree that exercise combined with a low-fat, high-fiber diet would be a winning combination for maintaining and improving health. Exercise is important in any health maintenance program. It is especially important in weight control since the amount of energy we expend in the resting state, our Resting Metabolic Rate (RMR), is a function of our muscle mass and tone.51,52 There is a tendency for us to lose muscle mass and gain fat pounds as we age. In part, this is due to life style changes. Instead of flying kites we fly desks! Nevertheless, our capacity to increase our muscle mass is undiminished with age.53 The lack of exercise rather than the abundance of candy is thought to be the primary cause of childhood obesity.54 Eating a low-fat, high-fiber diet will produce some weight loss even in nor-mal weight subjects.55 The reason for this may well be the balance between fullness and satiety.56 It is a proven fact that we can easily eat an excess of fat before we feel full or satisfied. This is because fats are twice as energy dense (9 calories/ gram) as carbohydrates or proteins (4 calories/gram). By the time we are full, we have over eaten. Increasing our fiber intake helps us feel full. (Of course expensive gastric bypass surgery is another alternative.57) Eating a highfiber diet helps us to feel more than just full. Low-fat, high-fiber diets are found to lead to a general lowering of cancer rates.58 Though the above combination of exercise, low-fat, and high-fiber may work in theory; making the theory work in practice is quite another story. Technology works against us in some ways as evidenced by this comment a woman made about her husband’s physique: “He has added 20 pounds of lap since he got his lap-top [computer].” And just try to get a low calorie meal over your lunch hour. In Feburary 1996 McDonald’s, an international fast food franchise, announced that it would be dropping its five-year experiment with the low-fat McLean burger (12 grams of fat). Also gone from the menu will be the Chef’s salad and the side salad. The taste of the Big Mac (35 grams of fat) has apparently won out over its McLean competition. The salads seem to be a casualty of convenience. Eating a salad in the car after a quick pickup at the drivethrough can be a bit challenging. Fortunately, state-of-the-art research in the area of weight loss has discovered that through the addition of certain supplements and nutrients, the process of decreasing the amount of fat we process in the stomach and boosting the amount of fat we burn can be expedited. For those of us who suffer from a “fat imbalance” or a condition where we store more fat than we burn, it is often a matter of life or death to lose fat in order to protect our arteries and heart. The Secret t o Weight Loss . . . An Ounce of Prevent ion Most weight-reducing strategies have to confront the “after the fact” problem of burning already stored fat. Like most of our medical practices, we routinely become sick or fat and then go about the business of trying to remedy our ills. Despite Poor Richard’s advice that “an ounce of prevention is worth a pound of cure,” we continually eat high-fat diets, and wait until we have to pay the piper before most of us take serious action. It’s much easier to prevent a fat build-up than to reverse the damage that carrying extra fat stores can cause. Going on a diet is nothing less than torture and usually means giving up all the foods we like to eat. Yet dieting seldom gets to the root cause of our excess weight which most often is that we eat too much fat, when not dieting. The body begins to digest lipids in the stomach and intestines. The diagram in Figure 1 illustrates the steps involved in getting fat into our bloodstream.59 There are four steps in fat digestion: 1) acidolytic breakdown of food in the stomach; 2) enzymatic breakdown (lipolysis) of the fats (triglycerides, TGs) into fatty acids (FAs) and beta-monoglycerides (b-MGs); 3) formation of soluble mixed micelles with bile acids; and 4) absorption through the intestines. If we could tie up excess fat before it was absorbed, we could spare our physiological systems the stress of having to deal with that fat. Ideally then, what we need is a substance that prevents fat absorption.

June 13, 2005 07:43 PM
Celebrating Women: Age Is Just a Number by Carl Lowe Energy Times, March 10, 2004 As women age, their physical needs shift. The health challenges that face a woman in her thirties do not match those of a woman in her fifties. At the same time, some basic health needs stay constant: At any age, every woman requires a wealth of vitamins, minerals and the other natural chemicals that fruits, vegetables and supplements supply. She also constantly needs families and friends to support her spiritual health. As the internal workings of your body alter, your lifestyle must stay abreast of those adjustments. Peak health demands a finely tuned health program designed with your individual needs-and your stage of life-in mind. Ages 30 to 45 When it comes to maintaining health, younger women might seem to have it easier than older women. If they exercise and stay in shape, they maintain more stamina than women 10 to 20 years their senior. Unfortunately, many women in this age group mistakenly think they don't have to be as careful about their lifestyle habits and their eating habits as they will in later decades. But even if your health doesn't seem to suffer from poor eating choices or a sedentary lifestyle right away, your foundation for health in later life suffers if you don't care for yourself now. By age 45 you should have established the good habits that will carry you successfully through the aging process. As an added bonus, good lifestyle habits pay immediate dividends. If you pay attention to your nutrients and get plenty of physical activity when younger, you'll feel more energetic and probably enjoy better emotional health. Set Health Goals According to Gayle Reichler, MS, RD, CDN, in her book Active Wellness (Avery/Penguin), good health at any age doesn't just come to you-you have to plan for it. In order to stick to good habits, she says, "living a healthy lifestyle needs to be satisfying." Reichler believes that you need to picture your health goals to achieve them: "Every successful endeavor first begins in the mind as an idea, a thought, a dream, a conviction." Good health at this age and in later years requires a concrete strategy and visualization of how your body can improve with a healthy lifestyle. Your long-term health goals at this age should include an exercise program that will allow you to reach a physically fit old age with a lowered risk of disability. In addition, your short-term plans should encompass losing weight, staying optimistic, living life with more vim and vigor, increasing your capacity for exercise and lowering your stress. As Reichler points out, "Your long-term goal and your ideal vision establish what you want to achieve....[You should do] something good...for yourself every day and every week that makes your life easier and more consistent with your goals." Develop an Eating Plan Today, the average American gains about two pounds annually. As a result, every year a greater portion of the US population is obese and overweight. By controlling your food intake earlier in life, you may be able to avoid this weight gain. In his book Prolonging Health (Hampton Roads), James Williams, OMD, recommends basic changes to your diet that can provide long-term support of your health: Get Supplemental Help If you're in your thirties or forties and you don't take at least a multivitamin, start taking one today! A large body of research shows that taking vitamin and mineral supplements over a long period of time significantly supports better health. Calcium and vitamin D are two of the most important supplemental nutrients, helping to build stronger bones now that can withstand the bone-loss effects of aging. Calcium can also help keep your weight down. One study of younger women found that for every extra 300 milligrams of calcium a day they consumed, they weighed about two pounds less (Experimental Biology 2003 meeting, San Diego). In the same way, taking vitamin D supplements not only helps strengthen your bones, it can also lower your risk of multiple sclerosis (Neurology 1/13/04). In this study, which looked at the health records of more than 180,000 women for up to 20 years, taking D supplements dropped the chances of multiple sclerosis (although eating vitamin D-rich foods did not have the same benefit). And if you're thinking about having children at this age, a multivitamin is crucial for lowering your baby's risk of birth defects and other health problems. A study at the University of North Carolina at Chapel Hill found that women who take multivitamins during pregnancy lower their children's risk of nervous system cancer by up to 40% (Epidemiology 9/02). " Our finding, combined with previous work on reducing several birth defects with vitamin supplementation and other childhood cancers, supports the recommendation that mothers' vitamin use before and during pregnancy may benefit their babies' health," says Andrew F. Olshan, MD, professor of epidemiology at the UNC School of Public Health. "We believe physicians and other health care providers should continue to educate women about these benefits and recommend appropriate dietary habits and daily dietary supplements." In particular, Dr. Olshan feels that folic acid (one of the B vitamins), and vitamins C and A, are particularly important for lowering the risk of childhood cancers and birth defects. Ages 45 to 55 When you reach this in-between age-the time when most women have moved past childbearing age but haven't usually fully moved into the post-menopausal stage-you enjoy a propitious opportunity to take stock of your health and plan for an even healthier future. One thing that may need adjustment is your sleep habits, as sleeplessness is a common problem for women in this age group. Even if you haven't been exercising or watching your diet until now, it's not too late to start. Making lifestyle changes at this age can still improve your chances for aging successfully. For instance, it is at these ages that women should have their heart health checked. Research published in the journal Stroke (5/01) shows that having your cholesterol and blood pressure checked at this time more accurately shows your future chances of heart disease than having it checked at a later date after menopause, in your late fifties. " The premenopausal risk factors may be a stronger predictor of carotid atherosclerosis [artery blockages] because they represent cumulative risk factor exposure during the premenopausal years, whereas the risk factors...during the early postmenopausal years have a shorter time for influence," says Karen A. Matthews, PhD, a professor at the University of Pittsburgh Medical Center. In other words, Dr. Matthews' research shows that if you have high blood pressure and high cholesterol before menopause, you are at serious risk for a stroke or heart attack soon after menopause: These are important reasons that you need to start improving your health habits immediately. Increase in Heart Disease Before menopause, a woman's hormones and other physiological characteristics usually hold down her chance of heart disease. After menopause, when hormones and other bodily changes occur, the risk of heart attacks and stroke in women rises significantly. (Heart disease is the leading killer of women.) At least part of this increased risk is linked to the postmenopausal decrease in estrogen production. Dr. Matthews studied about 370 women in their late forties, measuring their weight, their BMI (body mass index, an indication of body fat compared to height), blood pressure, cholesterol and blood sugar. Ten years later, after the women had entered menopause, she and her fellow scientists used ultrasound to measure blockages in these women's neck arteries (a sign of heart disease). The researchers found that indications of potential heart problems (such as high blood pressure, high cholesterol and being overweight) when women were in their forties did indeed forecast future difficulties. " Women who had elevated cholesterol, higher blood pressures and increased body weight before menopause had increased blood vessel thickening and atherosclerotic plaque formation in the neck arteries after menopause. Such changes in the carotid arteries are associated with an increased heart attack and stroke risk," says Dr. Matthews. Heart Health Factors The four main lifestyle factors you should adjust at this age to support better heart function are diet, stress, exercise and weight. According to Dr. James Williams, "[M]ore than any other cause, dietary factors are the most critical factor in cardiovascular disease." He recommends eliminating "dietary saturated fatty acids as found in flame-broiled and fried meats." He also urges women to eat more fish and poultry, consume organic fruits and vegetables and cut back on refined sugar. Stress becomes an ever more important heart disease factor at this age as estrogen begins to drop. " Our study [in the lab] indicates that stress affects estrogen levels and can lead to the development of heart disease-even before menopause," says Jay Kaplan, PhD, of the Wake Forest University Baptist Medical Center (The Green Journal 3/02). Dr. Kaplan's research shows that stress in women ages 45 to 55 may reduce estrogen earlier in life and make women more susceptible to the arterial blockages that lead to heart disease. "We know from [lab] studies that stress can lower estrogen levels to the point that health is affected," he says. Stress can also hurt bone health: In a study of 66 women with normal-length menstrual periods, estrogen levels were low enough in half of the women to cause bone loss, making the women susceptible to osteoporosis. Exercise and Weight Although exercise used to be considered to be mainly a young woman's activity, the thrust of recent research suggests that physical activity actually becomes more important to health as you get older. A 17-year study of about 10,000 Americans found that exercising and keeping your weight down is probably the most important thing you can do to lower your risk of heart disease as you enter your forties and fifties (Am J Prev Med 11/03). Of the people who took part in this study, more than 1,500 people died of heart disease. Those who performed the most exercise were thinner and had a 50% chance less of dying of heart disease than overweight nonexercisers. " The fact is that those who both exercised more and ate more nevertheless had low cardiovascular mortality," says Jing Fang, MD, a researcher at the Albert Einstein College of Medicine in the Bronx, New York. An added benefit of exercise: If you burn up calories exercising, you can eat more and not have to worry as much about being overweight. Supplements and Diet If you're a woman at midlife, a multivitamin and mineral is still good nutritional insurance. Eating plenty of fruits and vegetables are also important for getting enough phytochemicals, the health substances in plants that convey a wealth of health benefits. As you enter this age group, your immune system gradually slows down. To help support immune function, eating produce rich in antioxidant nutrients, and supplementing with antioxidants like vitamins C and E as well as carotenoids, can be especially important. For example, a study of people with ulcers found that people with less vitamin C in their stomachs are more likely to be infected with Helicobacter pylori, the bacteria that can cause peptic ulcers and is linked to stomach cancer (J Amer Coll Nutr 8/1/03). This research, which looked at the health of about 7,000 people, found that vitamin C probably helps the immune system fend off this bacterial infection. " Current public health recommendations for Americans are to eat five or more servings of fresh fruits and vegetables a day to help prevent heart disease, cancer and other chronic diseases," says Joel A. Simon, MD, MPH, professor of medicine at the University of California at San Francisco. Calcium and Bones At midlife, calcium continues to be a vital mineral for supporting bone health. According to Gameil T. Fouad, PhD, "It has been routinely shown that a woman's calcium status and level of physical activity (specifically, the degree to which she participates in weight-bearing exercise) are positively associated with bone mineral density. It is less well appreciated that this is a process which takes place over the course of a lifetime." Dr. Fouad adds that calcium works in concert with other vitamins and minerals to keep bones healthy: "Research in the United Kingdom involving nearly 1,000 premenopausal women over age 40 illustrates those women with the highest bone density tended to have the highest intake of calcium. Surprisingly, this study also demonstrated that calcium does not act alone: those women with the best bone health also had the highest intakes of zinc, magnesium and potassium." Dr. Fouad stresses that supplements should go together with a lifestyle that includes enough sleep and exercise to help the body stay in top shape. " As a general guideline," he says, "a woman concerned with her mineral intake should take concrete steps to make sure she is getting adequate rest, is eating a well-balanced diet focused on fresh fruits, vegetables and lean protein as well as getting adequate exercise....A multi-mineral containing bio-available forms of zinc, magnesium, copper and selenium is probably a safe addition to anyone's routine. Taking these proactive steps dramatically reduces the chances that deficiencies will arise." Ages 55 and Beyond Entering the post-menopausal phase of life can present challenging opportunities for a new perspective on life and health. While some signs of aging are inevitable, experts who have looked at how the human body changes with age are now convinced that healthy lifestyle habits can improve how well you can think, move and enjoy life well past age 55. As Dr. Williams notes, "In your fifties, the force of aging is undeniably present: Your body shape changes and organ function declines, both men and women have a tendency to gain weight....Heart disease becomes more common, energy and endurance are considerably reduced and your memory begins to slip." But Dr. Williams also points out that you don't have to age as rapidly as other people do. He believes you should employ a "natural longevity program...[that starts] to reverse the course of aging as early as possible." One key to staying vital as you age is your outlook on life, an aspect of life that's greatly enhanced by strong social ties. Avoiding the Aging Slowdown The latest research shows that one of the most crucial ways to slow the effects of aging is to exercise and keep your weight down. It won't necessarily be easy, though. The change in hormonal balance at this age makes the body more prone to extra pounds (Society for Neuroscience Meeting, 11/12/03). " In women, it has been demonstrated that major weight increases often occur during menopause, the time in a woman's life in which cyclic ovarian function ends and the ovarian hormones estrogen and progesterone decline," says Judy Cameron, PhD, a scientist in the divisions of reproductive sciences and neuroscience at the Oregon Health & Science University. In Dr. Cameron's lab trials, she has found that the decrease in estrogen after menopause "resulted in a 67% jump in food intake and a 5% jump in weight in a matter of weeks." In other words, the hormonal changes you undergo as enter your late fifties causes your appetite to grow as well as your waistline: Developments that increase your chances of heart disease, cancer, diabetes, stroke and joint problems. Vigilance against this weight gain is necessary to save your health: Start walking and exercising. Research on exercise in people aged 58 to 78 found that getting off the couch for a walk or other physical activity not only helps control weight but also helps sharpen your thinking and helps you become more decisive (Proceedings of the National Academy of Sciences, 2/16-20/04, online edition). This recent study, done at the University of Illinois at Urbana-Champaign, found that performing aerobic exercise improved mental functioning by 11% (on a computer test). " We continue to find a number of cognitive benefits in the aerobic group," says Arthur F. Kramer, PhD, a professor of psychology at the Beckman Institute for Advanced Science and Technology at Illinois. "The brain circuits that underlie our ability to think-in this case to attend selectively to information in the environment-can change in a way that is conducive to better performance on tasks as a result of fitness." In simple terms, that means that walking at least 45 minutes a day boosts brain power as well as protecting your heart. An Herb for Menopause The physical changes that accompan> y menopause can be uncomfortable. But traditional herbal help is available: Black cohosh (Cimicifuga racemosa), an herb used for eons by aging women, has been shown in recent studies to be both safe and effective (Menopause 6/15/03). " This [research] should reassure health professionals that they can safely recommend black cohosh to their menopausal patients who cannot or choose not to take HRT [hormone replacement therapy]," says researcher Tieraona Low Dog, MD, Clinical Assistant Professor at the University of New Mexico Department of Family and Community Medicine. While HRT has been used to help women cope with menopause, a flurry of studies in the past few years have shown that HRT increases the risk of heart disease and cancer. Instead, black cohosh, which alleviates such menopausal discomforts as hot flashes, has been shown to be much safer. Keeping Track of Crucial Vitamins While continuing to take multivitamins and minerals at this age is important, some experts believe that as we grow older, vitamin D supplementation, as well as taking antioxidant nutrients, is particularly vital. Arthritis is a common affliction of aging, and rheumatoid arthritis (RA) is one particularly destructive form of this joint problem. But taking vitamin D can significantly lower your risk of this condition. When scientists analyzed the diets of 30,000 middle-aged women in Iowa over 11 years, they found that women who consumed vitamin D supplements were 34% less likely to suffer RA (Arth Rheu 1/03). Other vitamins are equally important to an older woman's well-being. For example, vitamins C and natural E have been found to lower the risk of stroke in those over the age of 55 (Neurology 11/11/03). In this study, smokers who consumed the most vitamin C and natural vitamin E were 70% were much less likely to suffer strokes than smokers whose diets were missing out on these vitamins. Rich sources of vitamin C in food include oranges and other citrus fruits, strawberries, red and green peppers, broccoli and brussels sprouts. Sources of vitamin E include vegetable oils such as sunflower seed, cottonseed, safflower, palm and wheat germ oils, margarine and nuts. Saving Your Sight After age 55, your eyes are particularly vulnerable. Eight million Americans of this age are at risk for age-related macular degeneration (AMD), a condition that destroys structures in the back of the eye necessary for vision (Arch Ophthal 11/03). But you can drop your risk of AMD by taking supplements of antioxidant vitamins and zinc, according to researchers at Johns Hopkins' Wilmer Eye Institute. Their research shows that a dietary supplement of vitamins C, natural vitamin E and beta carotene, along with zinc, lowers the chances of progressing to advanced AMD in certain at-risk people by about 25%. Daily supplements also reduced the risk of vision loss by about 19%. The carotenoids lutein and zeaxanthin also help protect aging eyes. When scientists compared healthy eyes with eyes suffering from AMD, they found that AMD eyes contained lower levels of these vital nutrients (Ophthalmology 2003; 109:1780). Furthermore, they found that levels of these chemicals generally decline as you grow older. Healthy at All Ages When it comes to designing a healthy lifestyle, general rules like these can be followed, but you should individualize your plan to fit your needs. No matter which type of exercises you pick out or what healthy foods you choose, look for a strategy and a plan you can stick to. If you think a selection of foods are good for you but you absolutely hate their taste, chances are you won't be able to stick to a diet that includes them. The same goes for exercise: Pick out activities that you enjoy and that you can perform consistently. That increases your chance of sticking to an exercise program. Staying healthy is enjoyable and it helps you get more out of life every day, no matter what stage of life you're in.

Date:
June 10, 2005 03:01 PM
Basics of the Immune System by Leonid G. Ber, MD Energy Times, September 1, 1998 In a world filled with pathogens and microbes, good health and resistance to disease is no accident. It requires a vigorous and vigilant immune system. The immune system should be viewed as an internal security force that is constantly checking the identity of everything entering and already existing in the body. A cell or substance may be recognized as "non-self" and a potential enemy if it does not have the right molecular make-up. A cell displaying molecules produced according to a different blueprint than the body's own code may be recognized as foreign. To eliminate alien material that may harm the body, the immune system must take swift action. Recognizing entities that originate outside the self forms the key to overall immune system response. This key is carried in the body by cells called macrophages (ma-kro-fajs), a name derived from a Greek term meaning "big eater." Macrophages eat or engulf foreign cells and molecules. When a macrophage encounters something that it distinguishes as being "non-self" or abnormal, it can attack the enemy with a series of assault weapons, including free-radicals (reactive substances) and enzymes, that dissolve and weaken the intruder. In fact, an enzyme produced by macrophages called lysozyme is recognized as one of nature's most powerful anti-infective agents. These chemical defenses, along with engulfment and complete digestion by macrophages, can effectively stymie invasion by disease-causing pathogens. Disease Invasion Harmful invasion can originate in the body's own cells as well as begin from outside sources. While we are constantly exposed to bacteria, viruses, fungal cells and parasites, destructive cancerous growths often start within the body. Every day, thousands of the body's cells mutate into possible cancers. Under most circumstances, the immune system keeps these cells under control. But when the immune "security" system slips up, these harmful growths multiply unrecognized. Getting Specific The initial immune response that recognizes invaders is called a "non-specific defense mechanism" since this immune response is generally the same toward all invaders. This counter-attack entails battling every invader pretty much identically: a macrophage can engage, dissolve, weaken, engulf, digest, eliminate. However, if, despite the initial immune efforts, the problem persists, a macrophage can tag an invader and "introduce" it to the rest of the immune system, thus recruiting more specialized types of immune cells to enter the battle. This tagging function endows macrophages with the name "antigen-presenting cells." (Antigens are substances that can provoke specific responses by the immune system.) Most antigens are proteins. Proteins are relatively large molecules made of smaller units called amino acids. The specific geometric organization of amino acids is what conveys uniqueness to each protein. (Your genetic code forms a blueprint for the production of your own, individual proteins.) Protein molecules produced by one human being can act as an antigen for another human being. That's why organs transplanted from one person to another can be rejected by the immune system. Unless organs are transplanted from one identical twin to another (who share the genetic blueprint for protein creation), doctors must use immune-suppressing drugs to curtail organ rejection. At the same time as these medicines prevent transplant rejection, they also make people more susceptible to infectious diseases and cancer. Specialized Immunity After one set of immune cells chemically tags antigens (invaders) for recognition, other highly specialized parts of the immune system go into action: Cells called T cells or T lymphocytes acknowledge the invaders and can take the further action (second line of defense) that is necessary to render them harmless. T cells get their name from the thymus (an organ located behind the sternum) where they originate. The thymus, most active when we're young, usually shrinks and apparently slows or shuts down its activity about the age of forty. A wide variety of T cells inhabit lymph nodes (soft, usually round, pea- or nut-sized organs) and other body areas. For instance, natural killer cells, as their name implies, are a particularly aggressive type of T cell. Another type of T cell is called T helper (a cell that supports development of immune response). T suppressors halt immune response when infection ends. In order to make all these different cells work in concert, cytokines or messenger molecules are produced that facilitate constant communications between all the parts of the immune system. The B Team Other organs of the immune system include: *bone marrow: a powerful cell producing organ where the majority of immune cells are born; *spleen: an abdominal organ that forms a reservoir for the production of immune cells. Lymph nodes oversee particular segments of the body where they collect and recycle tissue fluids. Like an early warning system, lymph nodes react when an invader is detected in the part of the body that it controls. Yet another step in the so-called immune cascade entails action by lymphocytes, called B cells, which originate in the bone marrow. These cells produce antibodies which are immune proteins (immunglobulins) that attack specific antigens. While traveling in the blood, an antibody can bind to an antigen, curtailing its harmful action. This bound up molecule forms a complex easily recognized by scavenging macrophages which make a quick meal out of the unlucky invader. After enemy cells are removed from the body, knowledge of this victory resides in the immunological memory prolonging your resistance toward specific disease pathogens indefinitely. That's why someone who has recovered from a disease like the measles may be impervious to reinfection. Rules for Optimum Immunity Even though the immune system consists of a complex team of hard-working cells, enhancing your immunity is relatively easy: Maintain a healthy lifestyle. Avoid continuous stress and negative emotions or cope with them through exercise or meditation. Consistent, moderate exercise can boost the immune system. Massage can also help although extreme care must be taken when inflammation or disease is already present. Sleep 7-8 hours a day. Sleep allows the body to recover and rebuild. Protein synthesis, vital for a healthy immune system, increases during the night. Stick to a healthy diet. Your immune system consists of trillions of cells. Consequently, nutrients important for cell health boost the immune system. A balanced low-calorie diet rich in complex carbohydrates, "good" fats (including fish oils, olive oil and flaxseed oil) along with vitamins, minerals and phytonutrient antioxidants from fresh fruits and vegetables can fortify immune cells. Plus, drinking plenty of water helps improve circulation of lymph fluid. These recommendations are not hard to meet once they become a part of your daily routine. However, extra immune security may be necessary during flu season, while traveling long distances (airplanes are notorious sources of pathogens) or when working extensive hours in front of a computer screen. In addition, exposure to x-rays, immunosuppressive chemicals, ultraviolet radiation (the sun) or simply aging may give your immune cells extra burdens. Your "specific" immune system does not respond immediately to the challenge of invasion by an infectious organism. Instead, it may require about 2 weeks for an effective reaction after antigen recognition and alerting T cells. During this period, the macrophages' non-specific defense assumes a crucial role in keeping infection in check. Enhanced activity by macrophages is especially important for recognizing and destroying cancer cells. The most dangerous cancers are those that can mimic normal cells and avoid the immune system's wrath. Few substances can activate macrophage function in the body (aloe vera contains substances that contribute to this process). The most powerful macrophage activator recognized by the scientific community is a sugar-like substance called beta-1,3-D-glucan. Beta-glucan, extracted from the cell walls of common Baker's yeast, when taken in certain small amounts, can prevent infection by making macrophages more active in recognizing and attacking infectious bacteria, fungi and certain viruses. This kind of activation can encourage macrophages to attack previously unrecognized tumor cells. As a result, tumors may be eradicated as the immune system mobilizes and produces what may be known as "spontaneous healing." Hungry Macrophages When a macrophage works overtime fighting disease, its demand for nutrients and energy increases dramatically. Vitamin C, known for its immune supporting function, seems to be especially important for maintaining fully active macrophages. Vitamin C collects in macrophages, often reaching forty times the concentration found in surrounding blood. What are conventionally considered normal amounts of vitamin C in the body may be insufficient to keep macrophages well supplied with this antioxidant. Therefore, extra amounts of vitamin C can keep the immune system in fighting trim. Scientists are only now beginning to uncover the secrets of the highly organized immune system. One thing's certain: The immunity security team depends on proper lifestyle, nutrition and supplements to maintain the critical defenses necessary for good health. Dr. Ber received his doctorate in internal medicine from the Yaroslavle, State Medical Institute in Yaroslavle, Russia.

Abstract Objectie :To investigate the effect of vinpocetine on cerebral blood flow (CBF) in the compromised circulation of a stroke affected hemisphere using transcranial Doppler (TCD) and near infrared spectroscopy (NIRS) methods. Methods : 43 patients with ischemic stroke were randomized into vinpocetine (VP) and placebo group in a double blind, placebo-controlled study of the effect of a single-dose i.v. infusion of vinpocetine on cerebral blood perfusion and oxygenation. In the VP group 20 mg VP in 500 ml saline, in the placebo group 500 ml saline alone were administered. The concentrations of oxy-, reduced- and total hemoglobin were measured by NIRS frontolaterally on the side of lesion while the mean cerebral blood flow velocity (CBFV), the pulsatility index (PI) and Doppler spectral intensity (DSI) were monitored by TCD in the middle cerebral artery on the same side. Values were averaged for the first 5 min prior to the infusion and for the last 5 min of infusion and they were compared between groups. Results : The concentration of all three chromophores increased during infusion in the VP group (mean dHbT=1.03, CI95=0.84, P=0.058; mean dHbO=0.92, CI95=0.91, P=0.071; mean dHb=0.10, CI95=0.21, P=0.297). The HbT and HbO showed a substantially smaller increase in the placebo group (mean dHbT=0.31, CI95=0.74, P=0.22; mean dHbO=0.57, CI95=0.80, P=0.094) while the Hb decreased (mean dHb=-0.26, CI95=0.29, P=0.05). Comparing to the placebo group Hb increased significantly in the VP group (P=0.027) while the increase of HbO and HbT did not reach the level of significance (P=0.29 and 0.11). DSI showed a significantly larger increase in the VP than in placebo group (dDSI=25.8 CI95=8.8 [VP]; dDSI=3.3, CI95=3.7 [Placebo], P0.005). The CBFV and PI did not differ significantly between groups. (dVm=5.02.98 cm/s [VP], dVm=4.12.57 cm/s [Placebo], P=0.28; dPI=0.08 [VP], dPI=0.09 [Placebo]; P=0.47). Conclusion :VP increases cerebral perfusion and parenchymal oxygen extraction as well. The increased perfusion was indicated by NIRS and by TCD measurement of DSI while conventional velocity and pulsatility measurements failed to detect theses effects.

Calm Child™
Calm Child is a clinically derived herbal formula, specifically designed to support many body systems that are critical to the health and well-being of children. It is truly a multi-purpose herbal treasure, useful for supporting the health of the immune system in winter, enhancing digestive processes, and promoting restful sleep issues commonly experienced by most children. It also helps defend the system against the negative effects of stress, eases occasional restlessness, and promotes calm focused attention. The Challenged Child Difficulty in focusing and concentrating is one of the fastest growing problems for children today. This is a "new" problem, recognized as such over the last thirty years of the twentieth century. In the nineties, up to 5 percent or more of all school-age children were identified as having issues with focus (greater than 5 million children in 1995, over 25% higher than in 1985!). Since then, this number has continued to grow. Signs of the problem include the following and must be present for at least six months in more than one setting (home, school, etc.) especially before the age of seven: distractibility (inattention); inability to concentrate or focus; impulsivity (poor self-control); and excessive activity. Of course, measures of all of these are very subjective and are a part of the development of almost every child. Additionally, situations such as premature separation from parents, or unresolved emotional issues, or a family crisis, can cause children to withdraw or, conversely, act out due to an inability to appropriately express their feelings. Further, excessive and violent TV and computer games, lack of physical exercise, and poor diets can cause over-stimulation, internally and externally. Determining when such behavior is a problem is subject to interpretation. Too often, children are provided with a diagnosis before they are out of pre-school and are far too often prescribed pharmacological interventions such as amphetamines (Ritalin). The Birth of Calm Child My husband, Michael Tierra, originally formulated Calm Child for our own child, Chetan, then one year old, to address a wide array of potential childhood issues. His underlying intention was to use Calm Child for all children, based on his belief that most childhood emotional complaints are due to the unconscious pain of separation from the security and comfort of the womb. It was also based on the fact that historically, botanicals have been widely used to support the development of healthy children. Chamomile and lemon balm are perfectly suited for this purpose. Both are incredibly gentle-acting and deliciously fragrant botanicals that promote relaxation and calmness. Both also address underlying digestive imbalances that can give rise to occasional irritability and restlessness. The Calm Child Formula The herbs in Calm Child have a long history of use for calm focused attention in children: Lemon Balm: In his herbal of 1640, the renowned English medical botanist John Parkinson quoted Serapion the Younger (802-849) who said lemon balm is used "to cause the mind and heart to become merry...to strengthen the weakness of the spirits and heart, and to comfort them..." This belief in the comforting effects of lemon balm persisted and was repeated by Avicenna, who stated "it makes the heart merry and strengthens the vital spirit." In the 16th century, the renowned herbalist Nicholas Culpeper reported on the use of lemon balm for melancholy and sadness. Herbalists and midwives today continue to use lemon balm for the same purposes. Chamomile: Well-known in the nineteenth century, chamomile was used for crying, weepy children and to support calm digestion. Herbalists have long recognized a relationship between upset stomachs and restless children. Today, it is still widely used in homeopathy for babies' teething and children's clinginess. Other complementary ingredients in Calm Child include: jujube seeds (zizyphus), one of the most nourishing and relaxing nerve tonics used in Chinese herbalism; the incredibly nourishing berries of hawthorn and amla; the calming, aromatic, and digestive promoting effects of catnip, anise, clove, and long pepper; the legendary gotu kola for promoting mental well-being and attention; and the minerals magnesium (taurinate) and calcium (citrate), both necessary for normal nerve and muscular function. Works in Three Important Ways Together these botanicals work in three important ways to promote calm focused attention in children. They: 1) promote a calm relaxed nervous system; 2) provide added nourishment which is essential for normal brain function; and 3) support a calm and healthy digestive system which is often an underlying cause of childhood restlessness. Clinical Experience Calm Child was developed more than 20 years ago and has been used by literally tens of thousands of children worldwide. In my own clinical practice, I have found Calm Child to have a wide range of uses. It is great as a wintertime supplement, to support normal digestion, promote relaxation and sleep, and perhaps most important, to cultivate a strong, centered, focused sense of mental and emotional well-being, specifically in children though many parents of active children have benefited from it as well. When it is given in conjunction with a diet that is low in refined sugars and food colorings and additives, parents report tremendous success in dealing with teething, occasional headaches and digestive imbalances, increasing attention in school, or helping their children cope with the stresses of day care. Dietary Considerations For best results, herbs are always given in conjunction with diet and lifestyle recommendations. When using Calm Child, make sure the child is eating sufficient protein for his/her needs along with lots of cooked vegetables and some whole grains. Include some fruit, but keep fruit juices to a minimum as they contain too much simple sugar for children. Eliminate sugar, white flour products, foods with colors and preservatives, and caffeinated products as much as possible. Be sure to give plenty of water (many children never drink water but depend on juices or sodas instead!). Also, children inherently have much more energy than their parent and teacher handlers who try to make them sit still and focus on something that has little meaning to them. Make sure they get plenty of physical exercise to burn off some of the energy that teachers and parents have difficulty harnessing.
