Analgesic Activity of Dichloromethane Extract of Valeriana jatamansi Roots

The present study was designed to evaluate the analgesic activity of Valeriana jatamansi (Fam. Valerianaceae) roots. The dichloromethane extract was subjected to analgesic activity evaluation on lacca mice using tail immersion test. The standard and test extract were administered per oral route. Dichloromethane extract of the roots exhibited significant dose dependent analgesic activity at 400 mg/kg, comparable to that of standard aspirin (100 mg/kg).
