As I have recently watched some friends being sucked into homeopathic remedies, I became more and more interested in this alternative modality. It's not hard to guess that (as it is with most of the alt-med stuff) the idea behind it makes no sense, the tests do not support it, and basically all you get is pure placebo effect.
Unfortunately, homeopathy is so popular that is actually can cause harm. For a lot of people, it also appears legitimate, since you are "taking a pill". They just don't realize there is nothing in it... NOTHING!!!
It's best to start off with this great resource: "The Ladybird Book of Homeopathic Treatment & High Street Chemists", and then read Orac's excellent "Studying homeopathy in Third World countries, revisited".
I also blogged in the past about an excellent book on the subject: A Few Books of Note...
Dig around, learn, understand, and don't get fooled into a treatment that does NOTHING, because it has NOTHING in it!!!
