Hemp oil is pressed from the seeds of hemp plants. Hemp oil used for consumption is typically unrefined and cold pressed, retaining a green color and nutty flavor.
Hemp oil is typically 56% linoleic acid, 22% alpha-linolenic acid, 9% oleic acid, and 2% and 5% stearic and palmitic acid respectively. It is a source of essential fatty acids, including omega-6 and omega-3 fatty acids. Its Omega-6 to Omega-3 ratio is considered “optimal”–in that the Omega-6 content does not significantly outweigh the Omega-3 content. Hemp oil supplementation results in incorporation of omega 3 and omega 6 fatty acids into the body’s circulating fatty acids. This has improved skin quality and skin conditions in humans.

While hemp grows from the cannabis plant, the psychoactive component, THC, is rigorously tested to ensure it is at a level that would not cause effects or trigger a drug test without unreasonably high consumption. This testing is done by a third party. Hemp’s linolenic acid is in the form of alpha-linolenic acid. Hemp oil spoils easily and should be kept cool and unexposed to light.
