Diabetic Foot Ulcer AmputationStudy Participants
80Chronic foot ulcers occurring among diabetic patients are difficult to heal. The frequent elderly age with co-morbidities, vascular insufficiencies, peripheral neuropathies and super imposed infections, all contribute towards the chronicity and failure of treatment. Preserving the ulcerated limb is the patients' wish. On the other hand, an infected ulcer that never heals just unnecessarily prolongs suffering. Nevertheless, patients earnestly like to try all methods of healing before accepting amputation.
Objective:To determine whether a course of herbal preparation used as an adjuvant therapy for diabetic patients suffering from chronic foot ulcers may promote healing so that major leg amputation can be avoided.
The Decoction is taken orally, twice a day, treatment period is 24 weeks The herbal formulation or a placebo was given as an adjuvant therapy for the treatment of the unhealing ulcers in these diabetic patients. The formula consisted of 12 herbs, viz: Radix astragali, Rhizoma atractylodis marcocephalae, Radix stephaniae tetrandrae, Radix polygoni multiflori, Radix rehmanniae, Radix smilax china, Fructus corni, Rhizoma dioscoreae, Cortex moutan, Rhizoma alismatis, Rhizoma smilacis glabrae, and Fructus schisandrae
Placebo taking orally, twice a day, 24 week treatment period The herbal formulation or a placebo was given as an adjuvant therapy for the treatment of the unhealing ulcers in these diabetic patients. The placebo was made with starch and colouring materials.
