Tamarindus indica (Caesalpiniaceae) bark is used in the treatment of pain traditionally, present work was undertaken to prove this scientifically by using suitable animal screening models as hot plate test and acetic acid induced writing test at the dose of 50 mg/kg, i.p. Petroleum ether extract showed significant increase in reaction time as compared to other extracts. Preliminary phytochemical test showed presence of sterols and triterpenes in the extract; hence these compounds might be responsible for analgesic activity.
