Andiroba virgin oil

The oil contained in the andiroba almond, known as crab oil or carap oil, is light yellow and extremely bitter. When subjected to a temperature below 25 °C, it solidifies, with a consistency like that of petroleum jelly. It contains olein, palmitin and glycerin.

The oil is used in Brazil to protect furniture from termites and other wood-chewing insects. Andiroba is native to the Amazon and is widely used by the indigenous populations of the northern region of Brazil.[4] The oil and fats of the almond are extracted and used for the production of insect repellent and compounds for traditional medicine.[2][3][4]
