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.
