Homeopathic remedies outperform placebo

The weight of high-quality evidence indicates that homeopathic remedies do not reliably outperform placebo. Systematic reviews of systematic reviews and Cochrane reviews consistently find no convincing evidence of efficacy beyond placebo across a range of conditions, though some meta-analyses of low-quality trials report small effects that do not survive bias adjustment.

Largest vulnerability: Significant uncertainty — conflicting evidence is the main limit: Support ratio 37% (direction: mixed) — evidence is genuinely split.

The competing case

The evidence is genuinely split. Here is each side and how it balances.

Competing claims we weighed

  • A meta-analysis of randomised, double-blind, placebo-controlled trials of non-individualised homeopathy found a statistically significant effect size favouring homeopathy over placebo.
  • A systematic review of meta-analyses of randomised placebo-controlled homeopathy trials identified evidence of efficacy across multiple indications, suggesting homeopathy performs better than placebo.
  • Homeopathic Oscillococcinum may reduce the duration of influenza illness, suggesting some efficacy beyond placebo.
  • Homeopathic remedies for adverse effects of cancer treatments show some positive evidence, indicating effects beyond placebo in this population.
