Heavy Metal Contamination in Homoeopathic Preparations: Regulatory Perspectives, Scientific Analysis, and Quality-Assurance Framework
Year: 2025
Type: article
Abstract: Heavy-metal contamination in homoeopathic medicinal products has emerged as a growing global concern due to variability in manufacturing practices, inconsistent raw-material sourcing, and limitations in regulatory enforcement. Although the method of potentisation reduces intrinsic toxicity when performed correctly, contamination may still occur from manufacturing equipment, raw materials, water sources, environmental exposure, or inadequate quality-control mechanisms. This review provides an expanded scientific analysis of contamination pathways, regulatory frameworks across India, Europe, the United States, and Australia, and contemporary analytical technologies such as ICP-MS, AAS, XRF, and chromatography-based assessments used for detecting metallic impurities. The article critically evaluates current Good Manufacturing Practices (GMP) under the AYUSH sector, highlights infrastructure limitations in small-scale Indian homoeopathic industries, and discusses the need for harmonised international standards. It concludes with recommendations for laboratory upgrading, evidence-based pharmacopeial revisions, and adoption of digital traceability to enhance public confidence in the safety of homoeopathic preparations. This literature review involves no human subjects and does not require ethical clearance.
