ELI5: How come homeopathy isn't illegal when there is clear evidence that the treatments don't work, leading to more deaths or propagation of serious illnesses?

It's kind of hard to nail down what about it should be illegal. The entire point in homeopathy is that the "medicine" is so watered down that there's nothing in it. You're drinking water, or eating a calcium tablet *and nothing else*. We can't exactly outlaw people drinking water.

What we *can* do, and what is done in many areas, is ban it from being sold as medical products. We typically don't allow it to be funded through public health care systems, and it generally stands zero chance of becoming approved by the local medical regulatory body (such as the FDA in the US).

We can't stop people from buying, selling or drinking water. But we can (and generally do) stop them from claiming that it is *medicine*.
