DOI: 10.1177/1534734605274574 The Role of Nutrition in the Management of Lower Extremity WoundsDepartment of Dermatology, University of Wales College of Medicine, Heath Park, Cardiff, UK, patelgk{at}cf.ac.uk From 3000 BC, healers have understood the importance of nutrition in wound care and used nutritional supplements to aid healing. Many of the teachings from Hippocrates, the father of modern-day medicine, clearly state his firm belief that good health can be achieved through nutrition. In the early 1900s when advances in biochemistry were frequent, many of the essential constituents of nutrition were characterized, which formed the basis for many animal and human wound-healing experiments. This led to the discovery of vitamin C, zinc, and many other components essential for the orderly progression of healing. Modern-day research has concentrated on finding nutritional components that can enhance healing through supra-physiological doses, such as in the use of the amino acids arginine and carnitine. However, clinicians need to be aware that approximately 50% of patients admitted to the hospital are malnourished, requiring dietary supplementation; appropriate nutritional assessment and advice therefore should be an integral part of all wound management. This review provides an up-to-date commentary on the role of nutrition in wound care, with specific emphasis on lower limb wounds, from a historical perspective, and within it both the biomedical approach and current herbalist practices are considered.
