Lady is soooooo right. Many drugs have their origins from herbs, like digitalis for the heart, now used in drug form by medical doctors. Stuff can hurt you. Know of one young guy who died taking some "natural" body building thing, one young girl very sickened with long-term affects by something bought by her Mom in a "natural" store. Please educate self about stuff offered before you take it. Didn't Twink's SIL do a "natural" colon rinse thing and get really bad stuff as a result? It contained a thing known to be bad? No one regulates these products or oversees them. DH cousin offered something to prevent bruising when my then 6 year fell. What!!!!!! Being as drug-free as possible, I refused. Kid got no bruise (it was not a big fall) and is 18 now.
