Siler Root (Fang Feng): A Wind-Dispelling Herb for Cold, Spasms, and Dampness
Introduction
Siler root, known as Fang Feng (防风) in Traditional Chinese Medicine (TCM), is a key herb for dispelling wind—whether wind-cold, wind-damp, or internal wind causing spasms. Light, acrid, and slightly sweet in nature, Fang Feng is used for symptoms like chills, body aches, trembling, and joint stiffness. It is a gentle yet effective herb for protecting the body from pathogenic influences, especially in the early stages of illness or in chronic bi syndromes (painful obstruction).
What Is Siler Root?
Fang Feng refers to the root of Saposhnikovia divaricata, a perennial herb native to northern China. In TCM, it is classified as acrid, sweet, and slightly warm, and it enters the Bladder, Liver, and Spleen meridians. Traditionally, siler root is used to release the exterior, dispel wind, relieve pain, and counteract dampness. It is known for its versatility in treating both exterior disorders and internal imbalances such as muscle spasms or joint pain.
