Wounds are an extremely common reason for consultation in emergency departments. They mostly result from traffic accidents but also of different traumatisms. Their healing is possible thanks to a natural, spontaneous and coordinated process set up by the body. This process can be accelerated by the use of synthetic, biosynthetic or natural healing...

... In addition, malaria continues to be one of the causes of mortality and morbidity. The African continent has a significant diversity of medicinal plants (Dibong et al., 2020). As a result of reduced access to conventional drugs in rural African areas where malaria is endemic, 80% of the population uses traditional medicine to cure malaria (AguiaDaho, 2020; Dénou et al., 2017;Gnondoli et al., 2015;Yolidje et al., 2020). ...
... The rats were divided randomly into four groups of 3 per group each. The test groups were treated with the different aqueous extract while control group received distilled water as described by Etame-Loe et al. [16] The rats were starved of food overnight prior to dosing. Following the fasting period, they were weighed, and the dose of the test substance were calculated. ...
... Older people generally provide more reliable information, since they are the holders of ancestral knowledge. In the department of Lom and Djérem, in the Eastern Region of Cameroon, Etame et al. (2018) found that the use of medicinal plants was very important for the age groups [31 -40] years (28.33%). The low interest in traditional medicine among those under 20 (3.33%) can, according to Mpondo et al. (2017) lead in the long term to a loss of the therapeutic uses of medicinal plants. ...
... Several ethnobotanical studies have been conducted in Cameroon on non-timber forest products. Most of them focused either on a specific species, or on a specific use or on the socio-cultural, economic or value chain value of these plants (Abdou et al., 2009;Betti et al., 2016;Ladoh-Yemeda et al., 2016;Mpondo et al., 2017;Sutjaritjai et al., 2019). Despite numerous studies, information on the uses of Leguminosae-Mimosoideae in Cameroon remains fragmentary, so that the contribution of these plant species to the needs of the population remains less known. ...
... These polar and non-polar activities of the extracts can be explained by the strong presence of polyphenols "antioxidant compounds" in the polar extracts and their absence in the non-polar extracts. Indeed, according to reports by several workers, polyphenolic compounds are capable of trapping free radicals, which explains their strong anti-free radical power (Biradar et al., 2016;Nga et al., 2017;Becker et al., 2019). ...
... ACT was recommended even in resource-poor settings where multidrug resistant (MDR) P. falciparum is a problem [2]. The WHO recommended that combination treatment rather than monotherapy should be used in areas where MDR to P. falciparum is problematic [4][5][6]. Combination drugs act at different sites or have different mechanisms of action. ACTs has been shown in many studies to have higher and sustainable parasitological cure rates over monotherapies, thereby reducing therapeutic failure rates, including P. falciparum resistant strains in sub-Sahara Africa malaria endemic countrie, compared to monotherapies [4]. ...
... Studies have revealed that alkaloid-rich plants such as Solanaceae, Apocynaceae and Rubiaceae are used to treat states of anxiety and mental disturbances [17] in the city of Douala in Cameroon. However, there are very few data on the pharmacological effects of S. aethiopicum leaves on diseases of the central nervous system, particularly anxiety disorders. ...
... In medicine, alkaloids are used as major analgesics (morphine), antimalarial (quinine), to combat excess uric acid (colchicine) [38][39][40][41][42][43][44] . Alkaloids from the leaves of Cymbopogon citratus would play an antipyretic role to lower the fever induced by diseases such as typhoid and malaria. ...

Plus généralement, sur les propriétés toxiques ou bien curatives voir par exemple références [44], effets anti-inflammatoires [46], agents potentiellement anticancéreux [50]. ...
... The traditional medicine remains the main recourse of a large majority of populations to solve their health problems, not only because it is an important part of cultural heritage, but also because of limited financial means in the face of conventional products [1]. Even today a majority of the world's population, especially in developing countries, treat themselves solely with traditional herbal remedies [2]. ...
