To determine the effect of Pueraria mirifica (PM) on serum parathyroid hormone (PTH) and calcium levels on aged menopausal monkeys (Macaca fascicularis), subjects were treated with 10, 100, or 1,000 mg/day of PM. Blood samples were collected every 5 days for 30, 90, and 60 days during pre-treatment, treatment, and post-treatment periods, respectively. Sera were assayed for PTH, estradiol, and calcium levels. PM-1,000 had the strongest effect on the decrease in PTH (0.001The results suggest that long-term treatment with 1,000 mg/day of Pueraria mirifica decreases serum PTH and calcium levels in aged menopausal monkeys, indicating that Pueraria mirifica ameliorates bone loss caused by estrogen deficiency.
