Dahurian Angelica Root Classic Formulas

Primary Actions

Expels wind and releases the exterior - Bai Zhi is used for wind-cold headache, body discomfort, and early-stage exterior patterns, especially when frontal pain is prominent.
Alleviates pain and opens the nasal passages - it is a classic herb for Yangming-channel headache, sinus congestion, rhinitis, and toothache centered in the forehead, nose, and gums.
Dries dampness and stops leukorrhea - its warm, aromatic, drying nature is applied to damp-related vaginal discharge patterns.
Reduces swelling and promotes discharge of pus - Bai Zhi is used for early sores, abscesses, and skin conditions where it helps open, vent, and move stagnation.

Jiu Wei Qiang Huo Tang - Bai Zhi helps release wind-cold and specifically addresses frontal headache in this classic exterior-dispelling formula.
Bai Zhi with Cang Er Zi and Xin Yi - the standard nasal-opening combination for chronic congestion, sinus blockage, and headache behind the brow line.
Bai Zhi with Huang Bai, Bai Zhu, and Shan Yao - a traditional damp-drying and discharge-controlling strategy for leukorrhea.

Traditional texts describe Bai Zhi as acrid and warm, entering the Lung, Stomach, and Large Intestine to release the exterior, relieve pain, unblock the nose, and dry dampness.
Because it enters the Yangming channels of the face, Bai Zhi is one of the most characteristic herbs for frontal headache, supraorbital pain, gum swelling, and toothache.
Older cautions consistently note that Bai Zhi's warm and drying fragrance is unsuitable for blood heat and yin-deficient dryness.
