Background: Cissampelos pareira Linn. is considered as an established source of Patha, whereas Cyclea peltata (Lam.) Hook. F. & Thomas is used as a source plant of Patha in the southern part of India. In classical texts, two different varieties of Patha, i.e. Rajpatha (C. peltata) and Laghupatha (C. pareira), are mentioned which possess almost similar properties. Objective: To compare antipyretic and analgesic activities of C. pareira and C. peltata in suitable experimental model. Materials and Methods: Powder (540 mg/kg) and ethanolic extract (200 mg/kg) of both the test drugs (C. pareira and C. peltata) were evaluated for antipyretic activity in Brewer's yeast-induced pyrexia model in rats. Analgesic activity was evaluated by radiant heat model in rats and acetic acid-induced writhing syndrome in mice. Results and Discussion: Result of the present study had shown that powder of C. pareira (540 mg/kg) has moderate antipyretic activity as compared to the powder of C. peltata and extract of both test drugs. C. pareira powder showed better analgesic effect than ethanolic extract (200 mg/kg) of both the test drugs in radiant heat model in rats, while in acetic acid-induced writhing syndrome, ethanolic extract (280 mg/kg) of both drugs showed pronounced effect as compared to powder form (780 mg/kg) in mice. Conclusion: Both C. pareira and C. peltata exhibited analgesic effects in experimental animals. The effect is more significant in C. peltata treated group compared to C.pareira. Antipyretic effect was observed with the pretreatment of C. pareira.
