Ancient herbal recipe tested to save diabetic legs from ulcers

This study tests whether adding a traditional Chinese medicine formula called Bu Yang Huanwu Decoction (in capsule form) to standard treatment can prevent leg pain at rest or foot ulcers in people with diabetic lower extremity vascular disease. About 300 adults aged 18 to 70 with diabetes and early to moderate leg artery disease will be randomly assigned to receive either standard care plus the herbal capsules or standard care alone for 6 months. The main goal is to see if the herbal formula reduces the chance of developing serious leg complications over one year.
