Natural Products from Chinese Medicines with Potential Benefits to Bone Health
Abstract
Osteoporosis is a progressive, systemic bone disorder characterized by loss of bone mass and microstructure, leading to reduced bone strength and increased risk of fracture. It is often associated with reduced quality of life and other medical complications. The disease is common in the aging population, particularly among postmenopausal women and patients who receive long-term steroidal therapy. Given the rapid growth of the aging population, increasing life expectancy, the prevalence of bone loss, and financial burden to the healthcare system and individuals, demand for new therapeutic agents and nutritional supplements for the management and promotion of bone health is pressing. With the advent of global interest in complementary and alternative medicine and natural products, Chinese medicine serves as a viable source to offer benefits for the improvement and maintenance of bone health. This review summarizes the scientific information obtained from recent literatures on the chemical ingredients of Chinese medicinal plants that have been reported to possess osteoprotective and related properties in cell-based and/or animal models. Some of these natural products (or their derivatives) m

Zheng He (also romanized Cheng Ho; 1371–1433/1435) was a Chinese admiral, explorer, diplomat, and bureaucrat during the early Ming dynasty (1368–1644). He is often regarded as the greatest admiral in Chinese history. Born into a Muslim family as Ma He, he later adopted the surname Zheng conferred onto him by the Yongle Emperor (r. 1402–1424). Between 1405 and 1433, Zheng commanded seven treasure voyages across Asia under the commission of the Yongle Emperor and the succeeding Xuande Emperor (r. 1425–1435). According to legend, Zheng's largest ships were almost twice as long as any wooden ship ever recorded, and carried hundreds of sailors on four decks.
A favorite of the Yongle Emperor, whom Zheng assisted in the Jingnan campaign that overthrew the previous Jianwen Emperor in 1402, Zheng He rose to the top of the Ming imperial hierarchy and served as commander of the southern capital Nanjing.
