Bupleurum (Thorowax) is a medicinal root found natively in East Asia. The Chinese name is Chai Hu (柴胡). The leaves of the plant are long and thin and resemble fennel.
- Traditionally used to relieve infections with fever, hemorrhoids and indigestion.
- Also used to treat liver stagnation (Qi), irritability, and liver disease.
Bupleurum is a primary ingredient an ancient Chinese medicinal formula known as Xiao Chai Hu Tang, first recorded in the Treatise on Cold Induced Febrile Disease (Shang Han Lun) circa 280 AD. The ingredients are:
- Bupleurum (root)16%
- Paeonia lactiflora (peony root) 16%

Another example of how Bupleurum is used in Traditional Chinese Herbal Medicine is in a formula called Xiao Yao San, which was first seen in the Tai Ping Hui Min He Ji Ju Feng (Imperial Grace Formulary of the Tai Ping Era) 1078–85. In this formula traditional practitioners use this combination of herbs with emphasis on Bupleurum to soothe irritability.
- Bupleurum (root) - Chai Hu - 14%
- Angelica Sinensis - Dang Gui - 14%

- Glycyrrhiza uralensis (root honey-fried) - 8%
- Herba Mentha (leaf) - Bo He - 8%
