“…As additive, poisoning antidote, aphrodisiac and medicines for therapeutic indication groups (such as digestive system, specific diseases and conditions, specific symptoms), a remarkable convergence or similarity of bark and seed uses is observed between Bipindi-Lolodorf-Akom II region and others regions throughout Cameroon (Akak, Bagangté, Binyenyale, Douala, Yaoundé, Kribi, the Center and South regions of Cameroon in general), Central and West Africa (Gabon, Equatorial Guinea, Congo, Ivory Coast, Ghana, Nigeria). From the perspectives of drug discovery and development using ethnopharmacological approach or method, the notion of convergence of use, considered as biological activity markers according to Fleurentin et al (2011), is a key concept to validate the source of information (Edwards et al, 2005;Heinrich et al, 2009) and therefore constituted one of the most useful approaches guiding the selection of plant species and/or plant parts for further pharmacological studies, ethnopharmacological experimental or clinical investigations. The ethnopharmacological method is particularly useful when J. Appl.…”

Guedje et al., J. Appl. Biosci. 2017 Garcinia lucida Vesque (Clusiaceae): from traditional uses to pharmacopeic monograph for an emerging local plant-based drug development 10594Journal of Applied Biosciences 109: 10594-10608 ISSN 1997-5902 Garcinia lucida Vesque (Clusiaceae): from traditional uses to pharmacopeic monograph for an emerging local plant-based drug development ABSTRACT Objectives: This paper seeks to assess information on the identity, traditional uses, safety and efficacy of Garcinia lucida Vesque (Essok in Boulou and Ewondo local language), in order to highlight it potential as species to be registered in medicinal plant list and formularies needed for the development of monographs leading to local production of phytomedicines. Methodology and Results: Ethnobotanical survey was carried in the Bipindi-Akom II region (South Cameroon) with the help of interviews based on standardised questionnaires addressed to key-informants. Bark and seeds were the major parts used, highly appreciated due to its properties in preventing consumers from poison, diarrhoea and headaches. The most important therapeutic indications were additive to palm wine, antidote to poisoning, gastritis and snake bite. Other uses in treating included gynaecological pains and infections, sexual diseases and cancers. The bark was also believed by local people to act on the stability of chemical antibiotic drugs in pharmacy, while leaves were used as insect repellent against mosquitoes and cockroaches. Conclusions and application of findings: As an additive in palm wine processing, poisoning antidote, aphrodisiac and medicines, bark and seeds are widely used in the Bipindi-Lolodorf-Akom II area, in the Centre and South regions of Cameroon, in Gabon and Equatorial Guinea, in Central Africa and West Africa. This similarity of use across many regions is considered as important biological activity marker tools guiding plant parts or species selection in drug discovery and development using ethnopharmacological approach. Through the ethnobotanical and biological tests, assessed, accurate information is provided to substantiate safety and efficacy of G. lucida and to satisfy the requirements of official compendia such as pharmacopoeia. Further studies are needed to understand the effects of bark and seeds as additive to palm wine, as well as the interaction between bark and chemical antibiotic drugs.

“…The questionnaire collected general information about respondents and also covered socio-economic data (Edwards et al 2005, Siddique et al 2005. Within the questionnaire, the respondents were asked in a direct approach whether or not they knew the six plants mentioned by Saint-Hilaire when he was in ES, namely: fedegosodo-mato, milhomens, erva do brejo, taririquim, batata de junça, and jarro.…”

Wild Food, Prices, Diets and Development: Sustainability and Food Security in Urban Cameroon

This article analyses wild food consumption in urban areas of Cameroon. Building upon findings from Cameroon's Comprehensive Food Security and Vulnerability Analysis (CFSVA) this case study presents empirical data collected from 371 household and market surveys in Cameroonian cities. It employs the UN Special Rapporteur on the Right to Food's framework for understanding challenges related to the availability, accessibility, and adequacy of food. The survey data suggest that many wild/traditional foods are physically available in Cameroonian cities most of the time, including fruits, vegetables, spices, and insects. Cameroonians spend considerable sums of their food budget on wild foods. However, low wages and the high cost of city living constrain the social and economic access most people have to these foods. The data also suggest that imports of non-traditional staple foods, such as low cost rice, have increasingly priced potentially more nutritious or safe traditional local foods out of markets after the 2008 food price crisis. As a result, diets are changing in Cameroon as the resource-constrained population continues to resort to the coping strategy of eating cheaper imported foods such as refined rice or to eating less frequently. Cameroon's nutrition transition continues to be driven by need and not necessarily by the preferences of Cameroonian consumers. The implications of this reality for sustainability are troubling.
