means An alternative medicine system based on treating ailments with substances diluted so heavily that often no molecule of the original ingredient remains, on the theory that 'like cures like' and that dilution increases potency.

from Coined around 1800 by a German physician who fused the Greek 'homoios' (similar) and 'pathos' (suffering) to name his 'like cures like' principle — treat an ailment with a tiny amount of whatever causes similar symptoms in a healthy person. The theory itself predates rigorous testing of dilution limits, and the 'succussion' rituals and extreme dilutions that define modern homeopathy were later refinements by its founder, not later distortions — he insisted the more diluted, the more powerful, a claim mainstream chemistry and medicine have never found supported.
