Green tea originated in China and it has been used as a beverage and for medicinal reasons in China and most of Asia. In Asia besides China, green tea is common in Japan, Korea, Vietnam and Thailand. The book written by 'Lu Yu' from the Tang Dynasty in China is to date considered as the most important book in the history of Green tea. The book is called the " Cha Jing" or "Tea Classic". It was written between 600 and 900 AD.
The book details the medicinal qualities of green tea which include, Easing effects on alcohol, curing blotchiness, acting as a stimulant, quenching thirst, curing the beriberi disease, eliminating indigestion, improving the brain and urinary functions and also preventing fatigue.

Recently, green tea has become popular in the west where Black tea was mainly consumed. Green tea today is being used as a raw material for extracts mostly used in beverages, dietary supplements, healthy foods and even in cosmetic items. Green tea varies in varieties depending on the country its grown, the growing conditions, the desired type of green tea, the production process and the harvesting time.

The general process of making a cup of green tea entails, using 2 grams of green tea leaves for 100ml of water or rather, a teaspoon of green tea leaves per a 5 ounce cup of water. When making green tea, the hottest temperature for the water should be between 81 degrees and 87 degrees and the lowest temperature should be between 61 degrees and 69 degrees. Low quality green leaves will mostly require more heating or steeping time than high quality tea leaves, however if you steep or heat for too long it may result in a bitter taste regardless of the quality of the tea leaves.
