Traditional knowledge on wild food plants in Doong village, Tan Trach commune, Bo Trach district, Quang Binh province, north central Vietnam

The purpose of the study was to document the traditional wild food plants used by tribal people in Doong village, Tan Trach commune. A total of 46 species were documented as wild plants used for food purposes. Among those species, 46 species are herbs followed by 21 trees, 7 shrubs, 10 herbs and 8 climbers. The present study accentuates the significant role of ethnobotanical researches, which needs to be documented by the extraction of traditional knowledge pertaining to the use of plants by future generations. The study could contribute significantly to Government policies to improve food security in tribal areas and in the improvement of wild vegetable status, whose potential as sources of nutrition is currently undervalued.
