Don't know...for me, I figured after 30 days of just lemonade I would dump in some good stuff rather than take the chance on bad flora populating. Andreas theory may be right on, but during a fast with syrup, the chances of candida flora propogating on their own is better. So, call me paranoid but I was more willing to ingest a good population instead of growing some on my own under the circumstances. Generally I wont eat probiotics unless there is a good reason, preferring instead Brown Cow with cream on the top or kefir....
The balm...well, the injury was pre-superbowl and I sat with my knee up during the game feeling no pain. The salve is an effort to *regenerate* and strengthen an old injury and so a long term effort with salve, tea and capsules. I have read testimonies for the stuff though and have begun to smear it other places...hope rings eternal and all twinges of pain are to be banished.
