Abstract

Pulsatilla nigricans Linn has traditionally been used in various disorders related to both male and female and proves a great remedy for ovaralgia, ovaritis, epididymitis, orchitis nervousness, sadness, mild restlessness and mental disorder. This investigation is designed to evaluate acute toxicity and anti-anxiety activity of ethanol extract of Pulsatilla nigricans leaves. The acute oral toxicity shows that, plant extract up to 5000 mg/kg produces no signs and symptoms related to toxicity and also no mortality was observed. Antianxiety activity of Pulsatilla nigricans was examined by using elevated plus-maze paradigm and hole-board paradigm in rats at two different doses i.e. 250 and 500 mg/kg, and significant anxiolytic effects were observed as compare to control.
