Hemp seed oil has a reputation as a versatile substance that is beneficial to us due to its Omega-6 to Omega-3 ratio and its content of essential fatty acids. Hemp seed oil is 80% essential fatty acid, the highest amount of any other plant. And because hemp seed oil so closely matches our own skin lipids, it is able to penetrate our cells and lubricate the surfaces between them. Hemp seed oil is used in cosmetics which take care of skin lesions and blotches that may occur as a result of excessively dry skin. Since it won't clog your pores like many other oils, you can safely use hemp seed oil to moisturize your skin, and do so without any greasy buildup. Hemp seed oil is also a natural sunblock, which helps people who use it to avoid diseases related to over-exposure to the sun's more harmful rays. The 3:1 ratio of Omega-6 to Omega-3 fatty acids is important in preventing heart disease and promoting heart health. The same ratio is thought to be helpful in alleviating the symptoms of skin conditions like acne, psoriasis and eczema. Hemp is the only plant containing Vitamin D, which is necessary for calcium absorption. This is especially helpful to those on a vegan diet.
