I've read the scientific reports, talked to researchers and healing practitioners and studied every piece of Kombucha literature that I could lay my hands on. After all of this, I believe that one of the primary reasons for the improved sense of health experienced by the Kombucha drinker is the fact that they are drinking tea. NOT herbal teas. Tea , especially green tea has a very high content of vitamins and minerals. Green tea also contains several B vitamins which are water soluble and quickly released into a cup of tea.
Green tea is also high in fluoride.
A cup of green tea provides approximately 0.1 mg of fluoride, which is higher than in fluorinated water. At the University of California, Berkeley, a research team found another substance in green tea - hexanes, which help prevent cavities. Scientific studies have shown strong evidence that green tea may help reduce the risk of strokes and heart disease, and may also prevent some cancers. They potentially defeat cancer by at least three mechanisms. First, they can shut off the formation of carcinogens, secondly, they turn up the body's natural detoxification defenses, and finally, they suppress cancer promotion.
