Bupleurum chinense, commonly referred to as Chinese Thoroughwax or by its traditional name chai hu in Chinese medicine, is a perennial herb native to East Asia, particularly found in grasslands and on the edges of fields and roads. It is characterized by its long, thin leaves that resemble those of fennel and small, yellowish flowers that bloom in umbels, typical of the Apiaceae family, during the summer months. The plant usually reaches a height of 30-90 cm (12-35 inches). Its roots, known as Radix Bupleuri, are harvested for medicinal use after the plant is a few years old.

Bupleurum chinense is valued for its medicinal roots, which are used in traditional Chinese medicine to treat liver issues, fever, digestive problems, and other ailments. The presence of compounds such as polyacetylenes and saponins are believed to contribute to its therapeutic effects. In cultivation, Bupleurum chinense requires well-drained soil, moderate watering, and full sun to partial shade. It is not commonly grown in ornamental gardens but is cultivated for its medicinal properties. It is generally considered safe and effective, with a history of use spanning thousands of years and millions of patients. However, gardeners should be cautious as it can potentially spread and become invasive if conditions are favorable.CC BY-SA 4.0
