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 journalCannabis and Cannabinoid ResearchTrusted Sourcenote 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 theCannabis sativaplant. 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 asinflammation.
The oil from the hemp seed is highly nutritious and may be especially helpful for the skin.
Thevitaminsand fatty acids in this oil may help keep the skin healthy and prevent breakouts.
A2014 studylooking 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 a2014 reviewTrusted Sourcenote 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:
The fatty acid content of hemp seed oil may also be good for the brain, which requires plenty of healthful fats to operate properly. Hemp seed oil is also rich in other compounds that may help protect the brain.
Arecent studyTrusted Sourcein mice found that a hemp seed extract containing these active compounds was able to help protect the brain against inflammation. The authors note that hemp seed oil contains polyphenols, which may play a role in protecting the brain.
Although these initial results look promising, scientists need to carry out studies in humans to confirm the benefits of this oil.
The comprehensive nutrient profile of hemp seed oil means that it may also be good for the heart. However, much of the information that is currently available comes from older studies or research that uses animal models.
A2014 reviewTrusted Sourceconcludes that an increase in alpha-linolenic acid, one of the fatty acids in hemp oil, appears to reduce the risk of cardiovascular disease. This fatty acid, which doctors call linolenic acid, is also present infish oilsand flaxseed oil. However, the researchers call for more clinical trials to confirm these results.
The research on hemp oil is still relatively new, particularly in the United States and other places where restrictive laws have prevented researchers from fully exploring the potential of cannabis plants until recently.
As CBD comes into more common use in an increasing number of areas, research into the potential benefits of full-spectrum hemp oil may expand. As a result, scientists may find more evidence to support the potential benefits of the plant or even reveal new benefits. In any case, the future of research on hemp oil looks promising.
There is also still a small risk of THC getting into the system, even from hemp seeds, which normally contain no THC. The THC could be present as a result of contamination with other plant matter. The results of a2017 studyTrusted Sourceshow that some commercial brands of food-grade hemp seeds can have a THC concentration that is as much as 1,250 percent higher than the legal limit.
It is essential to ensure that hemp seed oil comes from a reliable manufacturer. The seeds and oil should be free of plant matter that may add additional compounds, such as THC.
