title: Puerarin exhibits weak estrogenic activity in female rats.
abstract: A weak estrogenicity of puerarin on reproductive organs was addressed in female rats. In short-term treatment, immature ovariectomized rats were injected with 0.7 mg/kg BW/day of puerarin, for 14 days. Puerarin did not increase uterus weights, endometrium and myometrium areas, and the percent of cornified cells (%Co), but it increased the number of uterine glands. In long-term treatment, mature rats were injected with 7.0mg/kg BW/day of puerarin for 140 days. Puerarin did not increase uterus weights, endometrium and myometrium areas, and the number of uterine glands, but a significant increase in the %Co was observed from day 98 onwards.
