I completely agree. Pretty much every substance out there can be bad for you if used excessively. They can all do different things, from overload your liver to damage your colon. That's why it's important to understand the dosage limits for anything you take, whether it's advil, senna or v1agra. Everything has a limit.
Which Liver Flush did you do? How'd you like it? Are those pic's of the stones you passed? I am interested in doing another one, and I am curious to see what flushes are out there?
