Plukenetia volubilis, commonly known as sacha inchi, sacha peanut, mountain peanut, Inca nut or Inca-peanut, is a perennial plant with somewhat hairy leaves, in the Euphorbiaceae. It is native to much of tropical South America.
In the Amazon Rainforest in Peru, it has been cultivated by indigenous people for centuries, and will grow in warm climates up to altitudes of 1,700 meters (5,500 feet) as long as there is continued availability of water and good drainage.
The seeds of inchi have high protein (27%) and oil (35 - 60%) content, and the oil is rich in the essential fatty acids omega-3 linolenic acid (≈45-53% of total fat content) and omega-6 linoleic acid (≈34-39% of fat content), as well as non-essential omega-9 (≈6-10% of fat content).
