Connaissances ethnobotaniques et valorisation de deux plantes antihypertensives (Carissa edulis L. et Crateva adansonii DC) au Sud et au Centre du Bénin (Afrique de l’Ouest)
Abstract
La prévalence de l’hypertension artérielle (HTA) augmente sans cesse et sa prise en charge par la médecine moderne devient de plus en plus onéreuse. La présente étude vise une analyse des connaissances des populations sur deux plantes (Carissa edulis et Crateva Adansonii) qui interviennent dans le traitement traditionnel de cette maladie en vue de leur valorisation. A cet effet, les connaissances ethnobotaniques issues de chacune de ces plantes ont été recensées à l’aide d’enquêtes semi-structurée et individuelle. Les résultats ont montré que les populations locales, dans leur grande majorité, ne connaissent pas toutes les utilisations faites de ces plantes. Ces deux plantes ont en commun l’usage médicinal, alimentaire et fourrager. A ces trois usages, s’ajoute l’usage médico-magique pour C. adansonii. Elles sont toutes utilisées contre l’HTA mais, C. edulis est principalement utilisée contre la faiblesse sexuelle (IF = 100%) et C. adansonii contre l’abcès (IF = 100%). Dans la préparation des remèdes traditionnels contre l’HTA, la racine de C. edulis et la feuille de C. adansonii sont sollicitées. En tenant compte de cette connaissance, un produit antihypertensif a été mis en place. Il est nommé “Thé-HTA”.

English Title: Ethnobotanical knowledge and valorization of two antihypertensive plants (Carissa edulis L. and Crateva adansonii DC) in southern and central Benin (West Africa)
English Abstract
The prevalence of arterial hypertension (HTA) is steadily increasing and its therapy by modern medicine is becoming more and more expensive. This study analyzed the knowledge of people on two plants (Carissa edulis and Crateva. Adansonii) involved in the traditional treatment of this disease in order to be valorized. To this end, ethnobotanical knowledge from each of these plants was identified through semi-structured and individual surveys. The results showed that the majority of local people do not know all the uses made of these plants. These two plants have in common the medicinal use, food and forage. To these three uses is added the medical-magic use for C. adansonii. Both plants are used against HTA but, C. edulis is mainly used against sexual weakness (IF = 100%) and C. adansonii against abscess (IF = 100%). In the preparation of traditional remedies for hypertension, C. edulis root and C. adansonii leaf are needed. By referring to this knowledge, an antihypertensive product has been made. It is named "Tea-HTA".
