Effect of Chinese Herbal Medicine on Renal Function in Diabetic Kidney Disease

This study is a randomized controlled pilot trial designed to evaluate the effects and safety of a traditional Chinese medicine formula (DKD-1) as an add-on therapy to standard treatment in patients with Diabetic Kidney Disease (DKD). Eligible participants will be randomly assigned to receive either standard care alone or standard care combined with DKD-1 for 12 weeks. Kidney function, glycemic control, proteinuria, quality of life, and traditional Chinese medicine tongue features will be assessed before and after the intervention. The study aims to provide preliminary evidence on whether DKD-1 can improve renal function, glycemic control, and quality of life in this patient population.
