Study of the effect of a Chinese medical preparation, hokoei-to, on the rat ovary.
Female rats were given Hokoei-to orally to investigate its effects on hormones. Progesterone and estradiol levels fell markedly in ovariectomized young rats. Administration of Hokoei-to for 25 d produced increased levels of hormones in these rats. A similar effect was found in parous rats, demonstrating replacement of the lost female hormones after Hokoei-to administration.
