Heavy metals and pesticide residue analysis plays an important role in the quality control of medicinal plants like Vasaka (Adhatoda vasica). Hence a study was conducted to determine heavy metals and pesticide residues in this medicinal herb, which is a highly useful commodity in the health system. The reliable, rapid and nontoxic sample preparation method like QuEChERS and analytical methods like GC-MS were proposed for the simultaneous determination of pesticide residues and Heavy metal detection was carried out by ICP-MS. In this study, the presence of organophosphorus and organochlorine pesticides like alachlor, heptachlor, heptachlor epoxide, aldrin, dieldrin, endrin, etc was checked but not detected. Heavy metals like Arsenic (As), Cadmium (Cd), Mercury (Hg) and Lead (Pb) are traced in samples about 2.3005 ppb, 0.799 ppb, 2.290 ppb and 10.204 ppb respectively in the present study.

The past decade has witnessed a tremendous surge of interest in herbal medicines throughout the world. Aflatoxins are naturally occurring mycotoxins that are mainly produced by Aspargillus flavus and Aspargillus parasiticus and primarily contaminate food crops such as corn, groundnuts, and tree nuts as well as herbal medicinal plants in tropical and subtropical regions of the world. It is a lethal substance that intensely or at slower ingestion influences the strength of humans and animals. Aflatoxin study is vital for a safety perspective as they are extremely lethal and cancer-causing; to overcome the health effect of aflatoxins and for better assessment and standardization of herbal plant drugs.  The investigation includes worldwide regulations on aflatoxins with their acceptable ranges in commodities. With more controls for adequate dimensions of aflatoxins set up, present-day analytical techniques have turned out to be very modern, capable of accomplishing results with high accuracy and precision, appropriate for administrative research centers and post-reap sample testing in developed countries.
