Prior to my diagnosis of cancer, my yogi and friend introduced me to Kombucha as an addition to the yoga and other health changes I had made. After researching it -- I found that it was worthy of further inspection. I eventually did start my own and found that everyone who drank it, felt the same results that I was experiencing. I would implore everyone who is interested in alternative ways at improving health to invest a little time and explore the amazing benefits of Kombucha.

Here is one sight, but there are literally hundreds.
