The present study was carried out to evaluate analgesic and anti-inflammatory activities in Inula cuspidata stem and root extracts along with heavy metals estimation in stem and root powder. Stem and roots were extracted with chloroform (ICSCE, ICRCE) and methanol (ICSME, ICRME). Acute oral toxicity of all extracts was determined by OECD guidelines 425. Analgesic activity was investigated by using hot plate and acetic acid induced writhing models. Anti-inflammatory activity (acute) of all extracts was evaluated by carrageenan induced paw edema model. In addition, root and stem powder was screened for heavy metals (As, Pb, Cd, Hg) estimation using atomic absorption spectroscopy. In acute toxicity study no mortality was observed when each extract was orally administered with 2.0 g/kg. At the doses (100 and 200 mg/kg) ICRME followed by ICSME showed significant and dose dependent analgesic and anti-inflammatory effects compared with chloroform extracts. The heavy metals concentration in stem and root powders was found to be within the permissible limits as recommended by WHO for herbal raw materials. The findings of the present study validated the folkloric use of Inula cuspidata as analgesic and anti-inflammatory. In addition, the results intimate that heavy metals present in raw material were found to be within the defined limits, and it exhibits that the therapeutic efficacy of plant may not be effected, which can be otherwise possibly effected if the plant sequester high concentration of heavy metals from the polluted environment as well as from the soil rich in pesticides and sewage sludge etc.
