Bulgarian Propolis More Active Against Leishmaniasis

Activity of Brazilian and Bulgarian Propolis Against Different Species of Leishmania
Memorias do Instituto Oswaldo Cruz, 2007 Feb;102(1):73-77

Extracts of propolis samples collected in Brazil and Bulgaria were assayed against four Leishmania species - Leishmania amazonensis, L. braziliensis, L. chagasi from the New World, and L. major from the Old World - associated to different clinical forms of leishmaniasis

An overall analysis showed that for all the species evaluated, Bulgarian extracts were more active than the ethanol Brazilian extract. As the assayed propolis extracts have their chemical composition determined it merits further investigation the effect of individual components or their combinations on each Leishmania species.
