It is important to monitor the quality of the phytopharmaceutical product as its therapeutic potential depends on standardized delivery of active ingredients present in the botanical source. Minimal presence of toxic impurities like heavy metals (HMs) is warranted to ensure product safety and prevent hazardous health impacts. In the present study, conducted as part of the development of a novel phytopharmaceutical product, the chemical profile of 13 heavy metals (Fe, Cu, Mn, Zn, Ni, Co, Mo, V, Cr, As, Pb, Hg, and Cd) was studied in the whole plant, fruit, and rhizome of Bacopa monnieri, Hippophae rhamnoides, and Dioscorea bulbifera, respectively, from environmentally diverse regions in India. Most samples had HM profiles within permissible limits as established by regulatory authorities, with the exception of Cd and Hg in low-altitude regions. This study indicates geographical regions in India suitable for procuring raw materials to develop and manufacture phytopharmaceutical products.
