Anti-inflammatory and histopathological studies of leaves extracts of Croton bonplandianus in Albino rats.

Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently used for the treatment and prevention of inflammation with the increase in number of side effects. Traditional plants have been used to treat inflammation owing to lesser adverse responses. Croton bonplandianus being an anti-inflammatory plant is extensively utilized all over the world. The methanolic and aqueous leaves extracts of Croton bonplandianus were exposed to anti-inflammatory activity in the carrageenan induced paw edema against standard diclofenac sodium, followed by the histopathlogical examination. The highest dose of methanolic extract were shown significant anti-inflammatory action having a significant P-value (P<0.05-0.001) compared with the diclofenac sodium (P<0.01-0.001) and aqueous extracts (P<0.5-0.01). The histopathological examination illustrated the vasodialation with reduction in the intensity of edema, neutrophils infiltration and other inflammatory cells. C. bonplandianus being a reactive oxygen species scavenger, responsible to exert an excellent anti-inflammatory activity. The present study confirmed the anti-inflammatory potential of drug extracts and authors recommended its utilization in the treatment of pain, inflammation and relevant diseases in future. However, phytochemical screening is to be required for the complete evaluation of active chemical constituent (s).
