RESUMO

INTRODUCTION: The Gelao people are a unique minority in Southwest China with a unique culture for the utilization of edible plants, including a large number of medicinal plants. They believe that at least 61 species are edible and have medicinal value. Ethnobotany research can reveal the local knowledge of the Gelao people regarding the traditional use of plants and the relationship between this minority and their living environment to help retain and pass on this traditional knowledge forever. METHODS: Edible wild plants and their applied ethnic knowledge were investigated in three counties in northern Guizhou. Gelao residents were the main informants, and literature search, village interviews, participatory observation and quantitative ethnobotany evaluation were used. RESULTS: A total of 151 species of wild plants in 67 families are collected and eaten by Gelao residents, among which 61 species were considered to have medicinal value, accounting for 40.4% of the total, and 43 were listed in the Chinese Pharmacopoeia. There were 57 plant species with fruits as their edible parts, which are consumed as snacks, followed by 54 species whose young seedlings and leaves are the edible parts, most of which are consumed cold or stir-fried. Other edible parts included roots or rhizomes (bulbs), flowers, whole plants, seeds, fruiting bodies and stems. There were two consumption modes: raw and cooked. Raw foods were mainly consumed as snacks, which mainly comprise fruits. Cooked foods were mainly vegetables consumed cold or stir-fried. Some plants were used as seasonings, infused wines, condiments and grains. The main medicinal functions were nourishing and reducing heatiness. Nourishing plants were mainly "shen" plants and Liliaceae, while plants able to reduce heatiness were mainly Asteraceae. Others functions included anti-hangover, anticancer and insecticidal. There were 38 species of important edible wild plants (CFSI > 500) in northern Guizhou, which had a high utilization rate. Houttuynia cordata Thunb. and Mentha suaveolens Ehrh. were the most representative edible wild plants in this area. The species, edible parts, edible categories, consumption modes and medicinal functions of edible wild plants in this area are diverse, and the traditional knowledge on their uses is rich. However, the number of wild plant species eaten by the informants and their related knowledge were positively correlated with age, which indicates that the rich traditional knowledge in this area is gradually disappearing with urbanization. CONCLUSIONS: The Gelao have a rich history of consuming wild plants. With the development of the social economy, the traditional knowledge passed from older generations is gradually being lost and its inheritance is facing great risks. This study collects, sorts and spreads this precious traditional knowledge, which is of great value to its protection and inheritance and fully demonstrates the value and importance of our work.
