Kombucha is a fermented beverage consumed by many cultures throughout the world. It has become more popular in the US over the last few years as alternative health care has become more popular. It is possible to make your own kombucha at home, but unless you really know and understand what you are doing it is better to buy the product to ensure you are getting a quality product.
Kombucha is made up of bacteria, yeast, B vitamins, acetic acid, ethyl alcohol and other acids produced during the fermentation process (see our article on fermented foods). Health benefits associated with Kombucha include boosting your immune system and liver function as well as improving your digestion. These benefits are provided through the antimicrobial action of the acids and by giving your intestine the good bacteria it needs in order to digest your food properly (see the article on Probiotics).
Although there are no specific human trials proving the efficacy of Kombucha, it has been used medicinally for thousands of years by traditional cultures and there is a significant amount of anecdotal evidence supporting its actions. Keep in mind that you should not drink more than 2 bottles a day and if you are drinking it on a regular basis then taking a break for a few days every few weeks will help keep your digestion balanced.
