ABSTRACT
In the present study selected medicinal plant samples used in the preparation of Indian herbal medicinal products were analysed, after nitric acid digestion, for the content of cadmium, mercury and lead, by atomic absorption spectrophotometry. The samples are procured by three method.1.Self collected from medicinal plant garden with the help of experts.2.Purchased from local drug collectors.3. Purchased from raw material stores. Result shows that 33% of sample analysed were contain toxic levels of cadmium, 40% were contain toxic levels of lead and no sample posses arsenic above the limit. (limit of cadmium, mercury and lead were 0.3,0.5 and 10 µg/g, respectively)
