Astragalus

What we refer to as the herbal astragalus is actually a large number of plant species in the family Fabaceae, the same group of shrubs that we commonly identify as peas, beans, or legumes. Many of these species have been utilized in folk medicine of different communities all over the world, but the majority of herbal extracts made available as nutritional supplements today come from Astragalus propinquus, or Astragalus membranaceus.

Astragalus may be best known for its touted modulating effects to the immune system largely owing to the fact that it has enjoyed a very long history as a health tonic both in the East and the West. It is an important ingredient in Traditional Chinese Medicine, valued for its reinvigorating effects to what they call defensive energy of life. It is known by the name of Huang Qi in China, where most of the recent studies on this herb take place.

Regulates Interferon Releases

There are a number of studies that link astragalus to HIV in that it is purported to combat replication of viruses and inhibit growth of pathogenic microbes. To be more specific, it is believed to have an influence on the production of proteins called interferon, or IFNs. A type of white blood cell in the employ of the immune system called lymphocytes release interferon whenever the body detects the presence of viruses, bacteria, parasites, or even tumors. In addition, IFNs activate natural killer cells, which target cells infected with viruses and tissues afflicted with tumor, and program them to die.

Stimulates the Healing Process

It is also postulated that astragalus has an augmenting effect on the healing process by interfering with inflammatory agents. There are organic compounds called eicosanoids that are released by the body in larger amounts to facilitate healing of wounds or infections through the process of inflammation. These compounds work hand in hand with the immune system in removing the pathogens that cause infections and initiate the reversal of damages done by these pathogens. If inflammation takes place longer than it is supposed to, the area affected will have to deal with prolonged pain, redness, and swelling. Astragalus works on the principle of maintaining healthy releases of eicosanoids, the reason why it is used as a treatment for arthritis, dermatitis, asthma, and other autoimmune diseases.

Produces Homeostatic Effects

Astragalus has shown to be involved in many metabolic processes, maintaining stability of organic compounds from the foods we eat that reach the circulation. There have been mentions that it is particularly good for the lungs, adrenal glands, and alimentary canal by improving their functions and acting as a buffer to any unwanted debris that may attack the cells that make up these organs.

Be reminded that astragalus has been associated with a long list of health benefits, but none of these have yielded strong scientific support. It is safe to assume that testimonials are influenced by anecdotal evidence and initial results of studies that are yet to be concluded.
