(From Wikipedia): Argan oil is an oil produced from the kernels of the argan tree, endemic to Morocco, that is valued for its nutritive, cosmetic and numerous medicinal properties. The tree, a relict species from the Tertiary age, is extremely well adapted to drought and other environmentally difficult conditions of southwestern Morocco. The species Argania once covered North Africa and is now endangered and under protection ofUNESCO. The Argan tree grows wild in semi-desert soil, its deep root system helping to protect against soil erosion and the northern advance of the Sahara. This biosphere reserve, the Arganeraie Biosphere Reserve, covers a vast intramontane plain of more than 2,560,000 hectares, bordered by the High Atlas and Little Atlas Mountains and open to the Atlantic in the west. Argan oil remains one of the rarest oils in the world due to the small and very specific growing areas.
Argan oil is exceptionally rich in natural tocopherols (vitamin E), rich in phenols and phenolic acid, rich in carotenes, rich in squalene, rich in essential fatty acids, 80% unsaturated fatty acids and depending on extraction method more resistant to oxidation than olive oil.
Argan oil is used for dipping bread, on couscous, salads and similar uses. "Amlou" a thick brown paste with a consistency similar to peanut butter is produced by stone grinding roasted almond and Argan oil and is considered a favorite local bread dip. The unroasted oil is traditionally used as a treatment for skin diseases, and has found favour with the cosmetics industry.
