What Is Hemp Seed Oil?
From the hemp plant, Cannabis sativa. Because both hemp and marijuana are from the genus Cannabis, they are often thought (erroneously) to have similar properties. In cosmetics, hemp seed oil is used as an emollient and to supply skin with omega fatty acids it needs to replenish itself and strengthen its surface against moisture loss. Specifically, hemp seed oil contains the omega-3 fatty acid alpha-linolenic acid and the omega-6 fatty acid linoleic acid. Hemp seed oil also contains beneficial phospholipids, plant sterols, amino acids (it’s especially high in the amino acid arginine) and is a rich source of antioxidant vitamin E. Another benefit of hemp seed oil is that it seems to enhance the benefits of cannabidiol, also known as CBD. This is likely due to the interaction between trace amounts of cannabinoids in hemp seed oil and pure cannabidiol.
