Drinking Kombucha on a daily basis is being Proactive with Prevention. You can purchase it at a Natural Food store or you can make your own at home. This was my attempt for home brewing. :>)
In my opinion, this is the best site for home brewing:
These raw Kombucha mushroom extracts and tonics, flavored tea drinks, and culture starter kits originated from organic sources and will always be made with the finest grade and certified organic ingredients! Unlike other sites selling commercial non-probiotic or pasteurized teas, preserved extracts, and mushroom culture kits with inferior ingredients or small pieces/cuttings of the mushroom culture.
They Sell Only the Best!
