FREITAS, A.V.L. et al. Diversity and uses of medicinal plants in homegardens at the community São João da Varzea, Mossoró, RN. Rev. bras. plantas med. [online]. 2015, vol.17, n.4, suppl.2, pp.845-856. ISSN 1516-0572.  http://dx.doi.org/10.1590/1983-084X/14_080.

Traditionally, at homegardens in the northeastern of Brazil, several plant species are employed for the treatment of diseases. The aim of this study was to research the species of medicinal use in homegardens of São João da Varzea, Mossoró, Rio Grande do Norte, Brazil. 22 homegardens were studied through the techniques of direct and participant observations , guided tours, free list and semi structured interviews. We verified the presence of 57 botanical species belonging to 37 families. The two species with the highest frequency of occurrence were the guava (Psidium guajava L.) and the coconut (Cocos nucifera L.), present in 59% and 55% of the homegardens, respectively. For these species there was more agreement of use (CUPc 61.5% and 92.3%). 67 diseases, including influenza and dysentery were the most common ones mentioned during the interviews. The main mode of administration was orally, in the form of decoction (58%), and the leaves were the most employed component (32.6%). Homegardens are systems that act as a more sustainable use of medicinal resources strategy since they conserve native species. The most common medicinal plants in the homegardens are the fruitful-food trees, important to the family income. The flu and the dysentery are the main health problems treated with medicinal plants by the community. The Ziziphus joazeiro Mart., Citrus X limonia (L.) Osbeck, Punica granatum L., Cocos nucifera L. and Psidium guajava L. are species that deserve further pharmacological studies.
