Diabetic foot disease is one of the difficult problems in the treatment of diabetes. Epidemiological surveys show that about 15% of diabetic patients develop diabetic foot and about 85% of diabetic patients have foot ulcers before lower limb amputation, and there is a combination of peripheral neuropathy, vascular disease and infection that causes the development and progression of ulcers, which leads to gangrene and amputation. This disease is the main cause of lower limb amputation disability in diabetic patients. This disease belongs to the category of “tendon gangrene” and “gangrene removal” in Chinese medicine. It is mainly caused by diabetes mellitus over time, depletion of qi and yin, loss of nourishment of the skin, stagnation of blood vessels, burning of the skin and (or) the accumulation of external evil causing qi stagnation, blood stasis, phlegm obstruction and heat toxicity, resulting in the decay of flesh and bone. Chen Deqing, a diabetic podiatrist at Chongqing Hospital of Traditional Chinese Medicine, has developed the “VSD Chinese medicine technique” for the treatment of diabetic foot, which is based on the Chinese medicine technique of resolving decay and regenerating muscle, and innovates the Chinese medicine external treatment method to achieve remarkable clinical efficacy. The VSD herbal medicine technique promotes the mechanism of wound healing: pulling the two sides of the wound together, stabilizing the periwound environment, reducing edema, removing exudate, and reconstructing the microstructure of the wound, thus increasing angiogenesis, increasing periwound blood flow, producing granulation tissue, reducing the level of bacteria, changing the biochemical and systemic reactions of the wound, and at the same time, the different “herbal medicine topical solution The different “Chinese herbal topical solutions” have different effects such as “clearing heat and detoxifying toxins, activating blood circulation, relieving swelling and pain, drying dampness and fire, resolving decay and regenerating muscle”, all of which can accelerate wound healing.
