During a three‐month study period, folic‐acid therapy was prescribed for 10 selected office patients (3 males and 7 females) with chronic leg ulcers. The average age was 61. Six of the 10 patients had venous stasis ulcers of various sizes. Four patients had ischemic ulcers. Folic acid was administered orally (as tablets) to all the patients in a dosage of 15 mg three times daily for twelve weeks. Four patients (2 with large varicose ulcers and 2 with ischemic ulcers) received an additional 20‐mg dose of folic acid twice weekly, intravenously.
In the first weeks of therapy most of the patients showed marked improvement. In 9 of the 10 cases, complete healing was achieved in six to twelve weeks. In the tenth case there was definite improvement but not complete healing of a toe ulcer.
Folic acid plays a dual role in the healing of leg ulcers. It is an effective vasodilator for the microcirculation, and a contributor to adequate protein metabolism.
