Spain will eliminate "alternative medicine" in its clinics, and will work to end the practice of teaching such "treatments".

This includes homeopathy and acupuncture. Homeopathy is absurd because it postulates differences between a treatment and a placebo that theoretically can't exist, and which no one can observe in practice.

Acupuncture is not obviously theoretically absurd, but experiment finds it is no different from a placebo.

The placebo effect may be useful, but there are lots of ways to trigger that.
