Analgesic,anti-inflammatory,and antipyretic activities of the ethanol extract from Desmodium caudatum
Abstract:
Context: In folk medicine in China, Desmodium caudatum (Thunb.) DC (Leguminosae) has been used to treat febrile diseases, rheumatic arthritis, and bacillary dysentery; nevertheless, there have been no reports on the analgesic, antipyretic, and anti-inflammatory effects of this plant in animals.

Objective: To investigate the analgesic, anti-inflammatory, and antipyretic activities of D. caudatum extract (DCE) in animals.

Materials and methods: The analgesic effect of DCE was measured in mice using the acetic acid-induced writhing test and the hot-plate test. The anti-inflammatory activity was assessed using the carrageenan-induced rat paw edema model and the dimethylbenzene-induced mouse inflammation model. The antipyretic effect was estimated using the lipopolysaccharide (LPS)-induced rat fever model. In addition, the acute oral toxicity of DCE was studied.

Results: DCE significantly and dose-dependently inhibited the writhing responses in mice, increased reaction time in mice in the hot-plate test, reduced carrageenan-induced paw edema in rats and the dimethylbenzene-induced ear edema in mice, and attenuated LPS-induced fever in rats. Furthermore, no death was observed when mice were orally administered DCE up to 40?g/kg.

Discussion and conclusion: DCE possesses evident analgesic, anti-inflammatory, and antipyretic activities, and has a favorable safety, which supports the use of D. caudatum as an analgesic, anti-inflammatory and antipyretic drug in folk medicine.
