TL;DR – Homeopathy, quite simply, is not a legitimate form of medicine.

Although surprisingly popular, there isn't significant scientific evidence that backs up the medical efficacy of the ingredients—like onions, poison ivy, and crushed bees—that homeopaths use (which are highly diluted to boot). While homeopathics have seen some successes, the uses—even discounting the lack of robust data—are limited. The use of homeopathy as a replacement for modern medicine, particularly in cases of more serious health issues, is incredibly dangerous; most data show that homeopathics function similarly to placebos. Furthermore, homeopathy may present active medical risks (aside from the passive danger of forgoing proper treatment), with the potential for overdose. Altogether, individuals are wasting their money (the actual homeopathic medicine is very inexpensive compared to standard medicine, but seeing homeopathic doctors is still very costly) and risking their health by opting for homeopathic treatment over well-tested and modern medicine.

I only partially disagree.

People will dismiss it as the "placebo effect".

But the placebo effect is not a dismissal. It is a real thing. Placebos can work for a decent number of ailments.

That said, selling water diluted in water in a solution with water for 50 bucks is a scam.

A skittle would work just as well.
