Uses
editThe timber is important, and oil is produced from the seeds. The name andiroba is from Nheengatu nhandi rob, meaning "bitter oil". Carapa guianensis produces oil similar[clarification needed] to neem oil.
The oil contained in the almond andiroba is light yellow and extremely bitter. When subjected to a temperature below 25 °C, it solidifies producing a consistency like that of petroleum jelly. The oil contains olein, palmitine and glycerin.[citation needed]
Andiroba oil is one of the most commonly sold medicinal oils in the Amazon.[citation needed] It is also used to repel mosquitoes by forming an oilseed cake into balls and burned, or mixed with annatto (Bixa orellana) and formed into a paste applied topically to protect the body from mosquito bites.[5]
Andiroba oil is extracted from light brown seeds collected from beaches and rivers, where they float after being shed by the trees or from the forest ground.
