Homeopathy: Principles, Scientific Consensus & Regulatory Status

Homeopathy is a pseudoscientific system founded by Samuel Hahnemann (1796) based on two unproven axioms:

1. Similia Similibus Curentur ("Like Cures Like") – A substance causing symptoms in a healthy person cures similar symptoms in illness.
2. Potentization – Serial dilution (often beyond Avogadro's limit, 12C/24X) with succussion allegedly increases potency. Final product contains zero molecules of original substance.

Scientific Consensus

• No plausible mechanism – Violates physics, chemistry, pharmacology.
• Clinical evidence: Systematic reviews (Cochrane, NHMRC, EASAC, WHO) conclude effects are indistinguishable from placebo.
• Major bodies reject it: FDA (not evaluated for efficacy), FTC (requires efficacy disclosure), NHS (UK) – ceased funding, EMA, AMA, Royal Colleges.

Regulatory Landscape

• US: Marketed as OTC drugs (HPUS) but not FDA-approved for any condition. FTC requires "no scientific evidence" disclaimer.
• EU: Registered as "traditional herbal" or homeopathic; no therapeutic claims without evidence.
• Canada: Licensed (DIN-HM) with risk-based review; labeling restrictions.
• Australia: TGA review; 2017 found no evidence for any indication.

Risks

• Delay of effective treatment (cancer, infections, chronic disease).
• Financial exploitation.
• Undermines trust in evidence-based medicine.
• Contamination/adulteration (poor manufacturing oversight).

Ethical Practice

Clinicians should disclose lack of evidence, obtain informed consent, never replace proven therapy, and document discussion.

Homeopathy is belief, not biology. Patient safety demands transparency.
