Stephania Root (Fang Ji): A Cooling Herb for Edema, Painful Joints, and Damp-Heat
Introduction
Stephania root, known as Fang Ji (防己) in Traditional Chinese Medicine (TCM), is a bitter, acrid, and cold herb valued for expelling wind-dampness, relieving pain, and promoting urination to reduce edema. It is commonly used for swollen joints, rheumatic pain, and fluid retention caused by damp-heat. In formulas, it is often paired with herbs that strengthen the Spleen and promote water metabolism.
What Is Stephania Root?
Fang Ji refers to the dried root of Stephania tetrandra, a climbing plant in the Menispermaceae family. In TCM, it is classified as bitter, acrid, and cold, entering the Bladder, Kidney, and Spleen meridians. Its strong draining and damp-resolving nature makes it especially effective for edema and damp-related joint disorders.
