Visceral leishmaniasis is an emerging and re-emerging disease that affects millions of people and animals. Currently, the treatment of this disease has been the subject of several discussions in scientific circles, as many believe that the treatment of animals affected by kala-azar may be generating strains that are resistant to the drugs available. As a result, alternatives for treatment are being studied, and the use of phytotherapy for this purpose is a vast field for study and research.
