OSTEOPOROSIS, OSTEOPOROSIS
Osteoporosis (OP) has a high incidence in the elderly, especially in postmenopausal women. Osteoporosis is called “silent killer” because of its long incubation period and no obvious symptoms in the early stage. According to statistics, by 2019, the global incidence of osteoporosis has exceeded 200 million, and an average of 20 fractures per minute is caused by osteoporosis [Recent studies have shown that women lose bone mass rapidly during the 5-10 years after menopause with an annual loss rate of about 1.5% to 2.5% [The use of evidence-based and comprehensive treatment can effectively relieve the patients' clinical symptoms. Some scholars have found that the effective components of kidney-tonifying herbs can promote bone formation and inhibit bone resorption. Under normal circumstances, the processes of bone formation are coupled and cooperated with bone resorption. In the case of osteoporosis, bone resorption is greater than bone formation, resulting in bone mass loss. Chinese medicine has unique advantages in the treatment of osteoporosis. However, there are few such scientific studies in clinic, and its application effect remains to be further confirmed [
