Screening of Mexican Medicinal Plants for Antiprotozoal Activity – Part II

Abstract

The activity of the crude extracts from eight medicinal plants used in Mexico to treat gastrointestinal infections were assayed against Entamoeba histolytica and Giardia lamblia axenic trophozoites. Alternanthera repens, Boerhavia coccinea, Flaveria trinervia, Leucaena esculenta, Tournefortia densiflora and Vitex mollis were found to have antiprotozoal activity, with extracts of Tournefortia densiflora being the most potent against both tested organisms.
