The gum resin is present in a suitable amount that the composition, when the solvent evaporates, will dry to form a solid coating that sticks to the skin or mucosal membrane to which the composition is applied and maintain the pharmacologically active agent over a sustained period of time in contact with sites on the skin or mucosal membranes exhibiting symptoms of the disease. Methods are provided for treating symptoms of 10 dermatological diseases with such a pharmacological composition. Biological dressings including tincture of benzoin and clotrimazole are shown to be efficacious for the long-term amelioration of symptoms of athletes foot.
