Most of the inhabitants of South Benin use medicinal plants to treat various pathologies. Several research studies have cited Vernonia amygdalina as a hepatoprotective medicinal plant. The objective of this work is to list the medicinal plants made available to the population to treat liver diseases by herbalists and to verify their level of knowledge in relation to the use of Vernonia amygdalina. The methodology consists of conducting a semi-structured survey of herbalists in markets, on sites where medicinal plants are sold and in households. This methodology allowed us to identify 38 species of medicinal plants belonging to 20 families. The best represented species is Bridelia ferruginea (10) of the family Euphobiaceae. The Rubiaceae family is the most represented (16). The organ of the plant most frequently used in recipes is the root (47). Five hundred and fifty-two households (552) responded to our questions. 64% use the leaves of Vernonia amygdalina for nutrition against 36% for therapeutic use. 68% are supplied from distant fields, 13% from urban areas and 19% from market gardening sites. 35% say they have no information about its use in phytotherapy, 21% use it for intestinal ailments, 18% for the treatment of malaria, 13% for oral diseases, 12% for other pathologies. The frequency of use (four times a week) is best represented for nutrition and phytotherapy. In conclusion, Vernonia amygdalina is very little known in phytotherapy despite the various researches carried out on this plant. Researchers must promote medicinal plants that are very easy to grow in order to limit the offer to users of rare plants in danger of extinction.
