Curcuma cotuana Luu, Škorničk. & H.Đ.Trần sp. nov.
Etymology: We name this species after the local Cơ Tu ethnic minority, who use various parts of the plant in their traditional medicine for its anti-inflammatory properties.
Vernacular name and uses: The vernacular name of this species, Pơr’vih in the Cơ Tu language, conveys an idea of keeping the living environment of people in the village peaceful and protected against bad spirits. The main rhizome is stewed with chicken and eaten by women after birth, giving them strength to work soon afterwards. It also reduces menstrual cramp in women. Raw root tubers are mixed with honey to treat coughs in children. Young leaves are mixed with rock salt to treat toothache and gingivitis. Fresh leaves are also used for wrapping fresh fish to preserve it from spoilage. The local people also believe that the plant possesses magic qualities preventing people from getting lost in the forest.
