Ethnoeconomical, ethnomedical, and phytochemical study of Argania spinosa (L.) Skeels.

Populations of the South-western part of Morocco traditionally use the fruits of Argania spinosa (L.) Skeels to prepare an edible oil whose obtainment furnishes, as side product, a cake used to feed the cattle and complemented the forage furnished by the leaves and fruits of this same plant. However, the wood of A. spinosa is also used for fuel and the subsequent induced deforestation is nowadays accelerated since populations are generally eager to replace argan-groves by cultures of higher and immediate benefits. Recently, argan tree, that is particularly well adapted to grow in arid lands, has been proposed by several agencies to slow down the desert progress in Northern Africa. In order to promote argan tree reintroduction by the South-western Morocco dwellers, a program aimed to increase the industrial value of A. spinosa is currently carried out in Morocco. A phytochemical study is included in this program. Traditional knowledge as well as the most recent results concerning A. spinosa are described in this review.
