Botanical Description
Bupleurum falcatum is a perennial herb in the carrot family (Apiaceae), growing 30-80 cm tall from a woody taproot. Stems are slender, branched, and somewhat woody at the base. Leaves are narrow, sickle-shaped (falcate), and parallel-veined, resembling grass blades. The inflorescence is a compound umbel of small yellow flowers. Fruits are oval to oblong, ribbed, and about 3-4 mm long. The root is brown externally and pale inside with a distinctive bitter taste and slight aroma.
Dry hillsides, grasslands, scrubland, forest margins, and rocky slopes; native to temperate Eurasia from Europe to eastern Asia, including China, Japan, and Korea.
Bupleurum falcatum is a widespread species across Eurasia. While some Bupleurum species in China have faced collection pressure due to high medicinal demand, this species remains relatively common. Sustainable harvesting practices are recommended.
Cultural & Historical Context
Traditional Chinese Uses
Chai Hu (bupleurum root) is a cool, acrid herb with an ascending, dispersing nature that makes it uniquely suited to resolving issues at the Shao Yang level of the body. It is used to harmonize the Shao Yang for the alternating fever and chills of Shao Yang syndrome, to spread Liver Qi for emotional depression, chest and flank tightness, and menstrual irregularities, and to raise sinking Spleen Qi for organ prolapse and chronic diarrhea. It is the primary herb in many of the most frequently used formulas in Chinese medicine.
