Context: Euphorbia hirta L. has been wildly used for its health benefits. It has been used as a decoction and to treat diarrhea, peptic ulcers, menstrual problems and venereal diseases. Aims: The study aims to investigate the estrogenic effects of E. hirta on ovariectomized (OVX) rats. Methods: The ovariectomized rats were divided into four groups, including those that received the vehicle (1\% v/v Tween 80, p.o.), 17\β-estradiol at a dose of 0.01 mg/kg B.W. and the ethanolic extract of E. hirta at the doses of 100 and 500 mg/kg B.W. These were administered daily for 14 days. Estrogenic activity was determined by analyzing the body, vaginal and uterine weight as well as the uterine and vaginal histopathology characteristics of the estrogen-induced response. Results: At the dose of 500 mg/kg B.W., the plant extract produced a significant increase in vaginal weight when compared with the ovariectomized rats, a slightly increase in the uterine weight and could induce hyperplastic epithelium and endometrial thickness of the vagina. Conclusion: The data in this work suggests that the plant crude extract showed weak estrogenic effects in ovariectomized rats and could be useful for health benefits for vagina atrophy of females during the menopause.

Objectives: To investigate the estrogenic effect of Avicennia alba (Blume) aerial parts as identified in the folklore recipes as a contraceptive Methodology: The estrogenic activity study of the methanolic extract was carried out by studying the histopathology of the uterus. The uterine weight and vaginal cornification were also observed. The diameter of uterus, thickness of endometrium and height of the endometrial epithelium were measured using a calibrated ocular micrometer. The estimation of total protein and cholesterol was carried out using a standard method described by Lowely et al. Results: The presence of alkaloids, anthraquinone glycosides, flavonoids, steroids, polyphenolics were detected in the aerial parts of Avicennia alba. The methanolic extract of Avicennia alba at 400 mg/kg body weight showed a significant (p\< 0.05) increase in uterine weight, diameter of uterus, thickness of endometrium and height of the endometrial epithelium compared to the control. There was increase in vaginal cornification status. The histological examination of the uterus also showed estrogenic influence. A significant increase (p\< 0.05) in total protein and cholesterol content in the uterus of standard and test drug treated rats was also observed. Conclusion: The methanolic extract of Avicennia alba at 400 mg/kg body weight showed significant estrogenic activity and the results are in consistent with the folkloric claim reports related to oral contraceptive effect of Avicennia alba
