Detection of Heavy Metals from Compound Herbal Drugs

Present study was conducted to determine the concentration of heavy metals from compound herbal drugs such as Dawa-ul-Misk Moatadil Jawahir Dar, Laboob-e-Kabeer, Majoon Dabeed-ul-Ward and Majoon Flasfa manufactured by national herbal products companies Ajmal Dawa Khana, Hamdard Laboratories and Qarshi Laboratories. Heavy metals such as Chromium, Cobalt, Cupper, Iron, Lead, Manganese, Nickel and Zinc were determined by using Atomic Absorption Spectrophotometer. The literature showed that concentration of heavy metals in different plants is always unpredictable and greatly varied. These variations might be due to contaminated soil, ill storage conditions of the raw material as well as contamination during any step of production. As determination of heavy metals from compound herbal drugs is a preliminary study. Therefore a detailed study is proposed to detect heavy metals from all the market available compound herbal drugs before use.
