Mayo Clinic on Kombucha Tea:
Health benefits attributed to kombucha tea include stimulating the immune system, preventing cancer, and improving digestion and liver function. However, there’s no scientific evidence to support these health claims.
So, because there’s no pharmaceutical company propping up the research and no FDA restrictions, proving this drink does any good is pointless. Fine, there’s no scientific tests conducted by the FDA and Kombucha isn’t regulated like Prozac or Sudafed but the next line grinds my gears.
There have, however, been reports of adverse effects such as stomach upset, infections and allergic reactions in kombucha tea drinkers. Kombucha tea is often brewed in homes under nonsterile conditions, making contamination likely. If ceramic pots are used for brewing, lead poisoning might be a concern — the acids in the tea may leach lead from the ceramic glaze.
So, we know nothing about this drink but if you drink it, you may die.
Thanks a lot.
