Pharmacotherapeutic effects of kuei-chih-fu-ling-wan (keishi-bukuryo-gan) on human uterine myomas

Abstract

Kuei-chih-fu-ling-wan (Keishi-bukuryo-gan; KBG), a traditional Chinese herbal remedy contains five components: bark of Cinnamomum cassia Bl. (Lauraceae), root of Paeonia lactiflora Pall. (Paeoniaceae), seed of Prunus persica Batsch. or P. persiba Batsch.var.davidiana Maxim. (Rosaceae), carpophores of Poria cocos Wolf. (Polyporaceae), and root bark of Paeonia suffruticosa Andr. (Paeoniaceae). This prescription has been frequently used in the treatment of gynecological disorders such as hypermenorrhea, dysmenorrhea and sterility. We previously reported that KBG might act as a LH-RH antagonist and a weak anti-estrogen on the uterine DNA synthesis in immature rats. In the present study, we investigated the effects of KBG on 110 premenopausal patients with uterine myomas. Clinical symptoms of hypermenorrhea and dysmenorrhea were improved in more than 90% of the cases with shrinking of uterine myomas in roughly 60% of the cases.
