Orginal kombucha is a fermented product from Green thee, but you can use it with different herbs to increase your healt.
I just started to brew my own using the following herbs->
Fo-Ti (Polygonum multiflorum)
Chaparral (Larrea tridentata)
Rooibos
Chamomile
Can't wait
Or you can brew health product using EM-1 only it is not as easy to brew Kombucha.
