Damp-Heat Toxins Accumulation Syndrome

This study evaluates the clinical efficacy and safety of a Modified Simiao Yongan Decoction when used alongside standard endovascular therapy and wound care for the treatment of diabetic foot ulcers. The trial focuses on patients presenting with the damp-heat toxins accumulation syndrome (Rutherford 4-5 or Wagner 2-4 classifications). Enrolling 120 participants, the study aims to observe the complete ulcer healing rate, limb salvage outcomes, and improvements in patient quality of life over a 6 to 24-month follow-up period.
