[Example of prescription] Angelica dahurica, Viscum album, Gentiana macrophylla, Asarum, Saposhnikovia divaricata, Angelica sinensis, Rehmannia glutinosa, White Peony Root, Ligusticum chuanxiong, Cinnamon Bark, Poria, Ginseng, Licorice, Eucommia ulmoides, Achyranthes bidentata.

[Literature excerpt] “Famous Doctors’ Records”: “Treats all kinds of wind, gout in all joints, no long-term new ones.”
“Tangye Bencao”: “Both are cold and damp, and the wetness cannot move or stop, and it cannot be cured without this.”
“Bencao Huiyan”: “It is a medicine that is good at moving blood, dispelling wind, dampness and cold. All symptoms of wind disease, such as the head and neck cannot bend and stretch, the waist and knees cannot bend and stretch, or the pain and difficulty in walking, numbness and uselessness, are all caused by wind and cold, and are injured by heat and dampness; it is necessary to use the bitter and pungent Duhuo to warm the qi and blood, and dispel the cold evil.”
“Bencao Qiuzhen”: “Qiang has the function of releasing the exterior, and Duhuo has the power to help the exterior. Qiang moves to the upper part of the body and If it is used upward, it can cure wandering wind headache and rheumatic joint pain. If it is used alone in the lower part of the body, it can cure latent wind headache and dampness in the feet. Although Erhuo is used to treat wind, its uses are different and must be carefully examined. ”
“Compendium of Materia Medica” says: “It has a strong smell and overflowing fragrance, so it can dredge all meridians, harmonize meridians, dredge tendons and bones, and benefit organs. If the cold and dampness are in the muscles and joints, it cannot reach the meridians and joints directly without using this strong smell. Therefore, it is an indispensable medicine for wind paralysis and paralysis.”
