Homeopathic medicines are obtained from raw materials of plant, animal, microbial, mineral or chemical origin through successive dilutions followed by dynamization or potentization, reaching infinitesimal, non-weight concentrations, which poses a particular problem in controlling the quality of these medicines according to today’s requirements, procedures and practices. Although today we have state-of-the-art analytical equipment that can achieve quantitative determinations in the order of nanograms or even picograms, we cannot perform quantitative determinations on homeopathic remedies that reach concentrations well below this order of magnitude. Therefore, the quality of homeopathic medicines can only be ensured through rigorous control and pharmaceutical-grade quality of the raw materials from which they are obtained, known as starting materials. This article aims to present the wide variety of raw materials that can be used for the preparation of homeopathic medicines, the quality requirements they must meet and the methods for determining their quality.
