You seem to be very knowledgeable about Chinese medicine. You should go to http://www.happyherbalist.com and read what Ed Kasper has to say about Kombucha Tea and also Chinese medicine, which he practices. You can even write him and ask questions and he will answer you.
As for the Candida, Kombucha Tea is very good for it. I belong to a Kombucha group and they have talked about it consistently. You would have to let it ferment a few days longer to get more of the Sugar out but the taste will still be pleasant.
