Even if you don't believe in Homeopathy (and you really shouldn't) you have to acknowledge the medical potential of potent poisons. For instance Shiga toxin from dysentery can be used to treat gastric cancer and a several snake venoms have been found to beneficial to the skin or cardiovascular system. There are many examples :D
I acknowledge that and point out that homeopathy has a dosage so low you can't really call it a dosage. Can't really overdose with homeopathy :P
Exactly, statistically speaking at some point homeopathic medicine does not contain a single molecule of the supposed active substance any more :D
