I don't know what you're trying to cure with OP. I don't think other than for general oral health (which is a gateway to other problems or cures) OP is really supposed to be any kind of heavy duty cure all.
If you're looking for heavy metal detox there are other therapies that work faster. For example, I've had unbelievably good luck with the Extremehealthusa.com brand of oral chelation. My chest pains (that I'd had 20 years) went away over night, and my arteries were clean and wide open as cofirmed by a catheter test. While I was using the product my body had this fantastically clean feeling as if I had fresh spring water instead of blood going through my vains. Nothing so dramatic with OP - but as an inexpensive and enjoyable daily protocal to maintain your health and keep you feeling young it's hard to beat. As a cure all - I'd be a skeptic too.
