I would report that after taking in for several days I developed constipation and lots of GI cramping. I'm thinking the levels had built up in my system. After researching it, I found an article where the it has been used to treat diarrhea in China for years. So I stopped taking it for a few days and the constipation and diarrhea miraculously went away. Conclusion: If it does cause side effects, I would say to just back off for a few days and let your body return to normal before taking more.
