Organic food enthusiasts are not, in my experience, the most sensitive to criticism. Homeopaths and their patients are. But there is no need for either group to get cross – certainly not with me. I am happy to pay for whatever works.

If I thought a homeopathic remedy could cure the persistent ache in my foot, I would swallow one today, but all my reading tells me that it would not. (Yes, dear homeopathy enthusiast, I know it cured your foot, but that is because homeopathic remedies are, as far as we can tell, placebos, which work only if you think they do, which I do not.)
