Homeopathy

Homeopathy fails where even placebo succeeds. A 2015 Australian National Health and Medical Research Council review of 225 studies found no reliable evidence that any homeopathic remedy works better than a sugar pill. This practice, invented by Samuel Hahnemann in 1796, dilutes substances so extremely that not a single molecule of the original remains—a process that makes it chemically identical to water. Despite 200 years of use, its performance lags behind #5 Astrology, which at least offers observational correlations; homeopathy's central claim of water memory has never survived a rigorous test. Concrete data from a 2005 Lancet meta-analysis showed no significant difference between homeopathy and placebo in 110 trials, cementing its status as pseudoscience's purest example.
