Dimyosan is known to help treat gout. The exact efficacy is related to the condition and other factors. Traditional Chinese medicine categorizes the basic pathogenesis of gout as dampness-heat underflow (dampness and heat invading the intestines, bladder, pubic area, lower limbs, etc.). Er Miao San is the formula of choice for treating the tendon and bone pain or redness and swelling of the feet and knees, wet sores in the lower part of the body, and the lower part of the belt. In the formula, Huangbai is a bitter and cold product, bitter for drying dampness, cold to clear heat, its nature of sinking, into the liver and kidney to clear the dampness and heat of the lower burner (dampness and heat invasion of the intestines, bladder, yin, lower limbs, etc.); Cangzhu is bitter in flavor, pungent and warm, attributed to the spleen, stomach meridian, bitter and warm, aromatic and dry, straight to the middle state, long for dampness and dryness in the spleen. The combination of the two flavors can treat both the symptoms and the root cause of the disease, and it can clear heat and dry dampness (removing heat and drying dampness). Although Ermiao San, as a classic Chinese medicine formula, has been widely used in the clinical field of gout treatment, but the use of specific drugs and detailed treatment plans need to go to a professional hospital, under the guidance of the doctor to use.
