The invention discloses a traditional Chinese medicine mixture for treating the pediatric membranous nephropathy. The traditional Chinese medicine holds that the pediatric membranous nephropathy belongs to the 'edema' range and relates to the lung, spleen and kidney three-viscera malfunction. Most of the pediatric membranous nephropathy is mainly characterized by insufficiency of both the spleen and the kidney, blood stasis obstructing the collaterals and internal stagnation of fluid-dampness. The operations of treating the root and strengthening the body resistance serve as the principal, and the operations of warming kidney and eliminating damp are assisted on the basis of invigorating spleen, supplementing qi and invigorating the circulation of blood. Therefore, the traditional Chinesemedicine mixture for treating the pediatric membranous nephropathy is prepared from the following traditional Chinese medicines of plantain seed, semen coicis, rust-coloured crotalaria herb with root, herba lycopi, the root of bidentate achyranthes, rhizoma sparganii, astragalus mongholicus, boschniakia rossica, herba epimedii, rhizoma polygonati and rhizoma atractylodis, wherein the traditional Chinese medicines have the efficacy on tonifying Qi, lifting yang, removing blood stasis, and inducing diuresis to alleviate edema. The obtained traditional Chinese medicine mixture is taken by patients. According to the clinical test of our hospital, the total effective rate of the traditional Chinese medicine mixture is 93.3%, and a treatment group is obviously superior to a control group on theaspects of lowering cholesterol (CHOL) and urine protein and improving albumin (ALB) and clinic efficiency.
