Gomortega keule (Mol.) Baillon, known locally as queule, is an endangered tree endemic to Chile. The literature states that the main uses of this species are fruit consumption and exploitation of the wood, but there are no in-depth references to other uses. Some references mention that the fruit produces a putative psychoactive effect. Because non-documented ethnobotanical knowledge may still be maintained by local people, this study aimed to gather information on traditional knowledge and uses of this tree. Local inhabitants in five localities were interviewed usingsemi-structured interviews. The main uses of the species already published were confirmed and detailed as more in-depth. Additionally, uses not previously described were found: for flavouring, dye and marbles. These uses are discussed, including the controversy about the inebriatingeffect of the fresh fruit.
