A word from David Brun
(Graduate of the Nanjing University of Traditional Chinese Medicine)
The name Bu Gu Zhi (补骨脂), i.e. the fruit of Psoralea corylifolia L., suggests that the function of this herb is to provide rich bone-repairing substances. Indeed, its action on the kidneys helps strengthen the body’s bones (the kidneys control the bones in Chinese medicine).
