Phytochemistry
P. tenuifolia contains tenuifolin, senegenin, and polygalacic acid.[1]
Medicinal uses
Yuan zhi is used primarily as an expectorant.[2] It is one of the 50 fundamental herbs used in traditional Chinese medicine, where it is called yuǎn zhì (Chinese: 遠志) and believed to have neuropsychiatric effects. It has been studied as a potential drug source in depression[3] and Alzheimer's.[4] However, quality of the herb varies widely, and as of 2020 there have been no toxicological studies or clinical trials.[4]
