I take ginger myself in addition, and please for your sake, don't try and do herbs only. It will suck, but a woman won't.

German commission E the body that is equivalent to our FDA over there holds more remiss for herbs. I am guess its something to do with money and shit. I also herd that maybe 50% of these thing's affects maybe be power of suggestion. My experience suggests they work fine.
That ginger dose in my avitar is total daily dose, and it should be divided through out the day, to make best use of ginger's antioxidant powers.
I could give a 4 page paper on sexual vitality, front and back. I got 2 dirty magazines for it to, probably stolen ones, either that or the person giving them to me felt sorry for me. I don't mind, I got something out of it, that is advantage, people thing your disabled, and you get stuff.
