Hemp oil can refer to a full-spectrum oil from the Cannabis sativa plant or hemp seed oil, which is oil that comes from just the seeds of the hemp plant.
There is very little risk of intoxication from hemp oil as all forms of hemp oil come from food-grain strains of hemp. The authors of a study in the journal Cannabis and Cannabinoid Research note that food-grain strains of hemp must contain less than 0.3 percent tetrahydrocannabinol (THC). THC is the compound that causes the so-called “high” of marijuana.
Hemp oil is not the same as cannabidiol (CBD) oil. The production of CBD oil uses the stalks, leaves, and flowers of the hemp plant, which contain a higher concentration of CBD, another potentially beneficial compound in the plant.
Hemp seed oil comes from the small seeds of the Cannabis sativa plant. The seeds do not contain the same levels of compounds as the plant itself, but they still have a rich profile of nutrients, fatty acids, and useful bioactive compounds.
Full-spectrum hemp oil that also contains plant matter may add other effective compounds, which may help with certain health issues, such as inflammation.
Skin healthThe oil from the hemp seed is highly nutritious and may be especially helpful for the skin.
The vitamins and fatty acids in this oil may help keep the skin healthy and prevent breakouts.
A 2014 study looking at the lipid profile of hemp seed oil found that it is rich in healthful oils and fatty acids.
The abundance of fatty acids may make the oil an excellent choice for nourishing the skin and protecting it from inflammation, oxidation, and other causes of aging.
The authors of a 2014 review note that the topical application of hemp seed oil strengthens the skin and makes it better able to resist infection. The authors also suggest that hemp seed oil may be a helpful treatment for a range of skin issues, including:
eczema
dermatitis
psoriasis
varicose eczema
lichen planus, an inflammatory skin condition
acne rosacea
These benefits are likely to be due to the high quantity of beneficial fats and other helpful compounds in the oil.
