Effects of Unkei-to on FSH, LH and estradiol in anovulatory young women with hyper- or hypo-functioning conditions

Effects of Switching to Wen-Jing-Tang (Unkei-To) from Preceding Herbal Preparations Selected by Eight-Principle Pattern Identification on Endocrinological Status and Ovulatory Induction in Women with Polycystic Ovary Syndrome

The objective of this study was to investigate the effects of switching therapy to Wen-jing-tang (Unkei-to) from previous selected herbal preparations on endocrine levels and induction of ovulation in women with polycystic ovary syndrome (PCOS). Sixty-four anovulatory women diagnosed with PCOS were enrolled in the study. After Kampo diagnosis, subjects received matched Kampo preparations (43 cases: Dang-gui-shao-yao-san, 21 cases: Gui-zhi-fu-ling-wan) selected by the matching theory of eight-principle pattern identification and Kampo diagnosis based on concepts of the qi, blood, and fluids as the physiologic activity. Fifty-four women who failed to ovulate after an 8-week treatment were randomly allocated to continuation of treatment with the preceding Kampo prescription (continuation group, n = 27) or treatment with Wen-jing-tang (switching group, n = 27). Plasma FSH, LH and estradiol levels were measured and ovulation rates were determined at the beginning and after an 8-week treatment with the preceding Kampo prescription, as well as after the subsequent 8-week treatment with the same preparation or Wen-jing-tang. No decrease in mean plasma LH level was observed in the 54 women who failed to ovulate among the 64 treated with a Kampo preparation. After the 8-week treatment with Wen-jing-tang, plasma LH levels were decreased by 58.2% ( p < 0.0001) and 49.4% ( p = 0.0005) in the groups switched from Dang-gui-shao-yao-san and Gui-zhi-fu-ling-wan, respectively. In the group switched from Dang-gui-shao-yao-san, a tendency towards increase in plasma estradiol level was observed (1.51-fold, p = 0.055), which was significant compared with that in the group switched from Gui-zhi-fu-ling-wan ( p = 0.032). The ovulation rate with switching of treatment to Wen-jing-tang was significantly higher (59.3%) than that with continued use of the same preparation (7.4%, p = 0.0036).

This study confirmed that Wen-jing-tang was effective in improving endocrine condition in the treatment of disturbances of ovulation in patients with PCOS without taking eight-principle pattern identification into consideration. This finding indicates that Wen-jing-tang is appropriate for use in treating PCOS in women with various constitutions (as determined by the matching theory of eight-principle pattern identification) in clinical practice and may prove to be a potent therapeutic agent with a wide therapeutic spectrum.

Efficacy of Nyoshinsan/TJ-67, a traditional herbal medicine, for menopausal symtoms following surgery and adjuvant chemotherapy for premenopausal breast cancer

We report a 39-year-old woman with premenopausal breast cancer who developed estrogen-deficiency symptoms associated with chemotherapy-related amenorrhea, and was successfully treated with Nyoshinsan/TJ-67, a Japanese traditional herbal medicine (Kampo). Six other breast cancer survivors with menopausal symptoms were also treated with Nyoshinsan/TJ-67, and five of the six patients showed noticeable improvement without adverse effects. Managing estrogen-deficiency symptoms in breast cancer survivors is still problematic, and Nyoshinsan/TJ-67 may be a useful and safe agent for such symptoms in these patients.
