Ethnomedicine and ethnobotany of Maerua subcordata (Gilg) DeWolf

Abstract

Background: Wild edible plants are valuable resources for improving food and nutritional security. Besides, they may provide important health benefits since the health-promoting components of plant-based foods usually exist at higher levels in wild plants. As a result, they are being sought as under-exploited potential sources of a health-promoting diet or a possible strategy to develop novel foods. In such exploration, ethnobotanical and ethnomedicinal data offer a fundamental step. The present study provides ethnomedicinal data on Maerua subcordata (Gilg) DeWolf (Capparidaceae). Methods: The ethnomedicinal data was collected from the Kunama ethnics of northern Ethiopia via focus group discussion and oral interview. Supporting ethnobotanical data from relevant literature was also compiled and systematically reviewed. Results: The results show that M. subcordata tuber is used by the Kunamas to manage malaria, malaria symptoms (fever, pain, gastrointestinal disorders), and seasonal cough while leaves are used for wound healing. In east Africa, its triple potential use as water purifying agent, food item, and herbal medicine was specified. As a herbal medicine, the tuber is used to manage a wide range of disorders including pain, infections, wounds, diabetes, blood pressure, and loss of appetite. Its use as laxative and abortifacient was also indicated. Leaves are used to treat wounds and ophthalmic and respiratory problems. As a food item, fruits are eaten during times of both food scarcity and food abundance while the tuber is used as a famine food. Conclusion: In East Africa, M. subcordata represents a wild food and medicinal plant, which may be developed into a functional food.

Induction of peroxisome proliferator activated receptor γ (PPARγ) mediated gene expression and inhibition of induced nitric oxide production by Maerua subcordata (Gilg) DeWolf

“…Its root tuber and leaf parts are used in traditional medicine to treat infections and for wound healing. Moreover, the root tuber is used to treat diabetes, high blood pressure, and allergic disorders as well as to improve appetite [27]. Inflammation is a common contributor to the pathology of all these disease conditions.…”

Ethnobotanical survey of herbs used in the preservation of food products in Fez, Morocco

“…This knowledge is also collected and documented by ethnobotanical studies to preserve the cultural heritage of the populations. Documentation of this information is helpful in recording local cultural traditions and enabling us to access important information [ 9 ].…”

Ethnobotanical survey in Tampolo forest (Fenoarivo Atsinanana, Madagascar)

“…In many parts of the world, traditional knowledge has always been transferred orally from generation to generation [18]. However, there is a risk of loss of information over the years, hence the importance of gathering them through ethnobotanical studies [4,[19][20][21][22][23][24]. In terms of traditional cures, despite the lack of written documents, forest medicinal plant species were used to treat various types of diseases.…”
