Homeopathy uses things like snake venom. And that sounds dangerous. They were talking about it in the late 80's. And one expert said, not really. Because they take a drop of snake venom, dilute it in a swimming pool of water, and then dilute that in another swimming pool of water. So what you get left is really mostly water. In fact in the 1980's, they tested some homeopathic cures. And that's all they were. Water. That's not in anyway dangerous. OTOH, you waste money curing disease with just water. And while you're taking that water for cancer, for example, you're wasting time you could be using getting chemo treatment. Now, that's dangerous.
