Aims: The aim of study was to evaluate the scientific basis for the traditional use of Elephantopus scaber leaves. Materials and Methods: In the present study, ethanol extract of Elephantopus scaber leaves was evaluated for preliminary phytochemical screening and antiasthmatic activity using histamine and acetylcholine-induced bronchospasm, mast cell degranulation and histamine induced constriction on isolated guinea pig tracheal chain at different dose levels. Student's t-Test and Dunett's test were used for statistical analysis. Results: The result of present investigation showed that the ethanolic extract of E. scaber significantly (P<0.001) decreased the bronchospasm induced by histamine, acetylcholine and protected mast cell degranulation as compared to control groups. It also decreased the histamine induce constriction on isolated guinea pig trachea in dose-dependent manner. Phytochemical studies revealed the presence of steroids, saponin, flavonoids, and phenolic compounds in the extract. Conclusions: The present study concludes that the antiasthmatic activity of ethanolic extract of E. scaber leaves may be due to the presence of flavonoids or steroids. Antiasthmatic action of the E. scaber could be due to its antihistaminic, anticholinergic and mast-cell-stabilizing property.
