No offense to anyone who believes in homeopathy, but I'm skeptical that it works. I've always figured maybe it works like the placebo effect or something. The patient feels better because they expect to feel better. I can see no harm in it other than some people forking over some cash for some dubious services.

On the other hand, all the products endorsed by the FDA do, in fact, have the potential to cause harm. These products are usually tested by the same company who developed them. They cherry pick the data to make their product look safe, then pay a huge fee and receive FDA approval. Nothing sketchy there, right?
