Crude hot water extracts from eight medicinal plants collected in Togo, West Africa, were examined for antimalarial properties against Plasmodium falciparum using an in vitro test. The activity differed with the plant species with extracts of Cassia siamea, Jatropha gossypiifolia and Pavetta crassipes capable of 100% inhibition.
