Argan oil can both be consumed and applied to the skin, hair, or nails. It may support heart health and reduce signs of aging. Argan oil has been a culinary staple in Morocco for centuries — not only because of its subtle, nutty flavor but also its wide array of potential health benefits. This naturally occurring plant oil is derived from the kernels of the fruit of the argan tree. Although native to Morocco, argan oil is now used across the globe for a variety of culinary, cosmetic and medicinal applications.
