The mogu tea, also known as kombucha (cum boo chuh), dates back to the 5th century A.D. Mogu is a fermented tea-like drink made from black tea, sugar, and a live pancake-shaped fungus with the consistency of a wet mushroom. Mogu produces acids similar to those made by the liver. It binds with toxins in the digestive tract and carries them out of the body via normal waste elimination. Mogu can help prevent and treat cancer. If prepared properly, it has no known harmful side effects in regular dosage of a cup or two a day.
