Cutaneous leishmaniasis (CL) is a protozoan disease of the skin caused by a wide range of italic species. The disease is endemic in many countries. It has been recognized as a major public health problem in Iran. Many treatments have been suggested for it but none of them was fully effective.

Exclusion criteria were: pregnancy, lactation, age less than 5 years and duration of disease more than 100 days. Each patient received garlic cream 5% or placebo for 3 weeks and was followed for another period of 40 days.
