I have used it myself, with similar results, for infections and viruses, etc. What it does is strengthen your immune system and fix your DNA, apparently. It seems to be ok to take it regularly, if you wish. Do watch the expiry date, though, as it does appear to lose effectiveness over time.
HOWEVER, children and women who are pregnant, wish to be, or breastfeeding should NOT take it, as I have seen warnings against that. Apparently it is even used as a type of birth control in some areas where it is grown.
