Hexane extract of Ferula jaeschkeana Vatke has been studied for its effects on reproductive organs in female cyclic rats. Its administrator for 10, 20 and 30 days stimulated the uterus as it increased the height of luminal epithelium and number of uterine glands. Ovary exhibited increased number of corpora lulea and absence of matured sized folicles. Extract also caused an increase in the wet weight of ovary and uterus. Amount of total proteins, glycogen and the activity of alkaline phosphatase were altered significantly in ovary and uterus.
