Cathartic activity of Cassia species.

Cathartic activity of the three Cassia species i.e. Cassia angustifolia, C. fistula and C. holosericea has been assessed by Lou's method. Comparative study revealed that C. angustifolia is more active as compared to C. fistula and C. holosericea. Furthermore, the comparative study of their Sennoside content also supports the above finding, as they bear some correlation between Cathartic activity and Sennoside contents. The legumes of all the three species were found to be mere active as compared to leaves in their Cathartic activity.
