Gathering an edible wild plant: food or medicine? A case study on wild edibles and functional foods in Granada, Spain

Abstract

A study on wild edible resources has been performed in the western part of Granada Province (Spain) using ethnobotanical methods. We document and analyze knowledge concerning wild edible plants and mushrooms and their folk medicinal uses in the study area. Several botanical features and use characteristics have been analyzed for the species included, with special attention to their medicinal uses, highlighting a large number of edible-medicinal species. Local importance of the medicinal uses for these resources has been confirmed. Up to 135 species are gathered from the wild in the study area, from which 46 can be considered folk functional foods. In addition, 45 crop plants with uncommon edible or medicinal uses are included, 29 of these being considered functional foods as well. Therefore, a total of 75 plant species are used as edible medicines which serve to treat 36 different conditions. The local concept of food and medicine regarding wild plant resources seems not to be well established. Studies on the pharmacological properties of these foods are needed in order to establish their real or potential benefits for the treated affections.
