Antiprotozoal activity against entamoeba histolytica of plants used in Northeast Mexican traditional medicine. Bioactive compounds from lippia graveolens and ruta chalepensis por Quintanilla Licea, Ramiro, Mata Cárdenas, Benito David, Vargas Villarreal, Javier, Bazaldúa Rodríguez, Aldo Fabio, Kavimngeles Hernández, Isvar, Garza González, Jesús Norberto, Hernández García, Magda Elizabeth

“…Because of the side-effects and the resistance that pathogenic protozoa build against the standard antiparasitic drugs, e.g., metronidazole, much recent attention has been paid to plants used in traditional medicine around the world in order to find new antiprotozoal agents. We collected 32 plants used in Northeast Mexican traditional medicine and the methanolic extracts of these species were screened for antiprotozoal activity against E. histolytica trophozoites using in vitro tests. …”
