Combretum micranthum (kinkeliba) is one of the most used medicinal plants in Senegal. However, its commercialization is poorly studied. The objective of this study is to analyze the commercialization of Combretum micranthum in Senegal. The study was carried out in two main regions of kinkeliba marketing in Senegal: Dakar, where kinkeliba is marketed; and Thies, where kinkeliba is produced and marketed.
Structured and unstructured surveys were administered to different categories of stakeholders: herbalists / traditional practitioners, collectors/ suppliers, retailers and consumers. Production sites that supply Dakar include the following: Diass, Sindia, Kiniabour, Pout, Thies Lalane.
The main sales points in Dakar are the Thiaroye and Grand Yoff markets. The kinkeliba marketing chain has short channels and women are the main stakeholders. Procurement is done by harvesting in the natural environment and by purchase for herbalists / traditional practitioners. The benefits and added value derived from the marketing of kinkeliba are positive and are increasingly evolving from producers to retailers. The kinkeliba chain, with its constraints and especially its strengths, requires better structuring and to be better known.
Keywords: Combretum micranthum, kinkeliba, commercialization, value chain, Senegal.
RESUMÉEn Afrique, l'espèce Zanthoxylum zanthoxyloides est largement utilisée dans le traitement de nombreuses affections comme la drépanocytose, les maladies inflammatoires et les douleurs. Les racines restent les parties de la plante les plus utilisées, ce qui pose le problème de la survie et de l'exploitation durable de l'espèce. Cette présente étude tente de trouver une alternative à l'utilisation des racines en médecine traditionnelle. L'activité anti-inflammatoire a été évaluée sur un modèle d'oedème induit par la carraghénine sur la patte de rat Wistar. L'activité analgésique a été quant à elle, évaluée sur un modèle de douleur à l'acide acétique sur la souris. L'extrait hydroalcoolique de feuilles montre une activité anti-inflammatoire à la dose de 100 mg/kg per os, avec des pourcentages d'inhibition de l'oedème de 36,64% et 50,13% respectivement à la quatrième et sixième heures. A la sixième heure, la dose de 300 mg/kg a une activité supérieure à celle de l'acide acétylsalicylique à la dose de 100 mg/kg, avec des pourcentages d'inhibition respectifs de 85,28% et 55,93%. Cet extrait à la dose de 300 mg/kg est doublé d'un effet analgésique qui est comparable à celui de l'acide acétylsalicylique à la dose de 100 mg/kg per os avec des pourcentages d'inhibition de la douleur respectifs de 72,91% et 73,21%. Ces résultats montrent que les feuilles et les racines sont douées de propriétés anti-inflammatoires et analgésiques. Dans une perspective de sauvegarde de l'espèce, les feuilles pourraient être utilisées à la place des racines dans la prise en charge de ces pathologies.
HIV / AIDS infection is characterized by the reduction of the body's defenses favoring the occurrence "opportunistic" infections, as bronchitis, mycoses and tuberculosis etc. Thus, to fight against this virus, antiretrovirals are used. The Ziguinchor district (Senegal) has a higher seroprevalence rate of 2.2% above the national average of 0.7%. It is in this sense that a survey of two herbalists, 35 tradipraticians and eight resource persons was conducted to identify the plants used in the management of opportunistic AIDS diseases because as the populations often resort to phytotherapy. 88 plants were identified and divided into 79 genera and 38 families. Some species were mentioned very more frequently and in many diseases. These are: Cordila pinnata Poir. (78%), Guiera senegalensis (73.1%), Khaya senegalensis (67%), Icacina oliviformis (55%), Terminalia macroptera (55%), Cassia sieberiana (47%), etc. Leaves and roots constituted the greatest use in the form of macerated, infused, for drinking, bathing, or fumigation, etc. The expected result during this study was the establishment of a repertory of medicinal plants used for the management of opportunistic diseases.
