Kombucha tea is a fermented beverage made by adding a symbiotic colony of yeast and bacteria to sweetened green or black tea. Natural health enthusiasts claim that kombucha tea prevents or cures a number of ailments, including cancer, but these claims are unfounded, according to Live Science.
Kombucha tea contains amino acids and B vitamins, which initiate muscle development and elevate the immune system. However, the Centers for Disease Control states that adults who do not have any pre-existing conditions should not drink more than 4 ounces of the kombucha tea per day to avoid any overconsumption risks. This CDC warning is intended to thwart any contamination that may occur from fermenting fungi and bacteria within homemade kombucha concoctions.
