Ethnomedicine is a study or comparison of the traditional medicine based on bio-active compounds in plants and animals and practiced by various ethnic groups, especially those with little access to western medicines, e.g., indigenous peoples. Often these traditions constitute significant interactions with insects as well, in Africa or around the globe. The word ethnomedicine is sometimes used as a synonym for traditional medicine. Ethnomedical research is interdisciplinary; in its study of traditional medicines, it applies the methods of ethnobotany and medical anthropology. Often, the medicine traditions it studies are preserved only by oral tradition. Often these traditions constitute significant interactions with insects as well Scientific ethnomedical studies constitute either anthropological research or drug discovery research. Anthropological studies examine the cultural perception and context of a traditional medicine. The purpose of drug discovery research is to identify and develop a marketable pharmaceutical product.
