Abstract

Mimosa pudica root powder (150 mg/kg body weight) when administered intragastrically, altered the oestrous cycle pattern in female Rattus norvegicus. Nucleated and cornified cells were absent in all rats. The smear was characterized by leucocytes only, as in dioestrus, which persisted for 2 weeks. There was a significant reduction in the number of normal ova in rats treated with the root powder compared with the control rats, and a significant increase in the number of degenerated ova.
