Bupleurum Powder (Chai Hu) Clears heat, regulates liver Qi, and raises the yang. It is used for treating the common cold when accompanied by alternating symptoms of chills and fever; malaria; chest pain; prolapse of the anus, uterus, and other internal organs; and irregular menstruation. Though it is classified as a cool, surface-relieving herb, it is commonly used in Chinese herbalism for stagnant liver qi, which refers to a pattern of symptoms including stifling feelings in the chest, flank pain, and emotional mood swings. For some, especially those with a tendency to yin deficiency, it can bring up unwarranted feelings of anger. This herb is also very well known for its sedative action, especially in the patented medicine Xiao Yao Wan (Bupleurum Sedative Pills). It is also effective for women with menstrual problems associated with PMS.Contraindications: Bupleurum should not be used by those with depleted fluids, those with liver yang rising, those with extreme headaches, or those with such eye diseases as conjunctivitis.Dose: 3-9 grams
