Bupleurum Root
Bupleurum Root (Chai Hu): A Qi-Regulating Herb for Liver Health, Stress Relief, and Fever Alternation
Introduction
Bupleurum root, known as Chai Hu (柴胡) in Traditional Chinese Medicine (TCM), is a foundational herb used to soothe the Liver, regulate qi, and harmonize interior-exterior imbalances. Light, aromatic, and slightly bitter, Chai Hu is often used to relieve stress, PMS, emotional constraint, and conditions that involve alternating chills and fever. Its upward and outward energy makes it ideal for dispersing constrained qi and lifting the mood.
What Is Bupleurum Root?
Chai Hu refers to the dried root of Bupleurum chinense or Bupleurum scorzonerifolium, members of the Apiaceae family. In TCM, it is classified as bitter, acrid, and slightly cold, entering the Liver, Gallbladder, Pericardium, and San Jiao meridians. Traditionally, Bupleurum root is used to regulate Liver qi, release the exterior (especially in shaoyang conditions), and guide other herbs upward to the upper body. It’s a cornerstone herb in formulas designed to restore emotional and energetic balance.
