Also, the placebo effect shouldn't be used dismissively. If you convince someone they should be feeling pain (tell them they're next to a low frequency transmitter that causes pain when they're really next to an empty speaker box), that pain is real in the sense their nervous system can have a physical reaction to it. It is in their heads, but perceptions can generate physical responses.
The classic study was on asthma treatments. Patients would subjectively report feeling better when on the placebo treatment, but the objective measurements of lung function showed no difference.
If people report being in less pain or less depressed when on a placebo treatment but attempt & complete suicide at the same rate... well, fuck.
Homeopathy doesn't work, that's a fact, what part about that known fact seems to confuse you? Why are you insisting something that is KNOWN to not work, works? What don't you get?

No they aren't.
When you run a well-conducted trial you find zero benefit to homeopathy. When you run a poorly-conducted study, with poor blinding or weak randomization you find some benefits to homeopathy. When you don't even run a study, but just give people homeopathy in clinics they'll tell you it works because they say they can feel a difference.
