Oral zinc for arterial and venous leg ulcers.

Leg ulcers affect up to one percent of people at some time in their life. Leg ulceration is chronic in nature with ulcers being present for months and in some cases years without healing, and with a high risk of recurrence. Management approaches include dressings and the treatment of underlying medical problems such as malnutrition, lack of minerals and vitamins, poor blood supply or infection.
