The Star-Shaped Inca Peanut of the Upper Amazon

Cultivated for over three millennia in the cloud forests of the Peruvian Amazon, the climbing vine Sacha Inchi (Plukenetia volubilis) produces distinct 6-pointed star-shaped green pods containing edible seeds celebrated as the "Inca Peanut".


1. The Highest Plant-Based Omega-3 Concentration

Cold-pressed virgin Sacha Inchi oil contains one of the highest concentrations of polyunsaturated fatty acids of any plant species on Earth:


  • 48% to 50% Alpha-Linolenic Acid ($ALA$ - Omega-3).

  • 36% Linoleic Acid (Omega-6) with an optimal 1.4:1 ratio that helps balance inflammatory eicosanoids.

  • Naturally rich in $\gamma$-Tocopherol and $\delta$-Tocopherol, preventing oxidative rancidity without artificial preservatives.


2. Clinical Cardiovascular Lipid Benefits

Human clinical trials demonstrate that consuming 10 to 15 mL of cold-pressed Sacha Inchi oil daily significantly reduces arterial systolic stiffness and lowers total serum cholesterol.
