Fang Feng, also known as Saposhnikoviae Radix or Siler Root, is a slightly warm, sweet, and acrid herb used in Traditional Chinese Medicine (TCM) to expel wind, release the exterior, and alleviate pain. Despite its name, which means “Guard Against Wind,” Fang Feng is unique among wind-expelling herbs for its ability to treat both wind-cold and wind-heat conditions. It is also used to relieve spasms, stop diarrhea, and treat wind-damp conditions affecting the muscles and joints.
Functions & Benefits
Releases the Exterior & Expels Wind
Fang Feng is effective for early-stage wind-related exterior syndromes, including both wind-cold and wind-heat. It treats symptoms such as chills, fever, headache, and body aches. Its balanced nature makes it safe for individuals with deficiency and those prone to catching colds.
Expels Wind-Dampness & Relieves Pain
This herb is commonly used to treat wind-damp bi syndrome, especially when joint pain is more mobile than fixed and worsens with wind or damp exposure. It is helpful for rheumatic pain, numbness, or a heavy sensation in the limbs.
Relieves Spasms & Controls Tremors
Fang Feng is used to treat internal wind with symptoms such as muscle spasms, trembling, and tetany. It is often included in formulas for childhood convulsions or tremors caused by Liver wind.
Stops Diarrhea & Treats Intestinal Wind
Fang Feng can be used to stop diarrhea due to Spleen Deficiency and internal wind, especially when diarrhea occurs at irregular times and is accompanied by abdominal pain or cramping.

Early-stage colds or flu with chills, fever, and body aches.
Wind-damp bi syndrome with joint pain, stiffness, or numbness.
Spasms, tremors, or convulsions from internal wind.
Chronic diarrhea due to Spleen Deficiency with wind involvement.

Common TCM Patterns Treated by Fang Feng
Fang Feng treats Exterior Wind-Cold or Wind-Heat, Wind-Damp Bi Syndrome, Liver Wind stirring internally, and Wind affecting the intestines or skin. These patterns typically involve chills, fever, pain that moves around, spasms, diarrhea, or itching.
Precautions & Contraindications
Not suitable for cases with true heat or Yin Deficiency with internal wind.
