A pilot study of a Kampo formula, EH0202, with intriguing results for menopausal symptoms.

OBJECTIVES: To investigate the effects of EH0202, a Japanese herbal supplement, on the immune and endocrine systems in women with menopausal symptoms. DESIGN AND SUBJECTS: Thirty-two (32) postmenopausal women (53.0 +/- 5.1 years old) presenting with menopausal complaints were enrolled in a clinical study. Patients were given an herbal supplement, EH0202 (6 g per day for 6 months) and were assessed for reduction of their overall symptoms using Greene's Climacteric Scale and Visual Analog Scale. Plasma interleukin-6 (IL-6), soluble IL-6 receptor, tumor necrosis factor-alpha, granulocyte macrophage-colony stimulating factor (GM-CSF), granulocyte-colony stimulating factor, follicle-stimulating hormone (FSH), and luteinizing hormone concentrations were measured before and 6 months after EH0202 administration. RESULTS: There was a significant decrease in the climacteric scale score (p = 0.0007) and visual analogue scale (p < 0.0001) after 6 months of EH0202 treatment. There was significant increase (p = 0.0097) in plasma GM-CSF levels and a significant decrease (p = 0.018) in plasma FSH levels after 6 months of EH0202 administration. CONCLUSIONS: EH0202 (MACH) decreased the plasma FSH level and stimulated myelopoiesis through the cytokine system, thereby clinically reduced menopausal symptoms in postmenopausal women. Therefore, in postmenopausal women, this product probably acts as an immunomodulator and endocrine modulator.
