Hemp seed oil is derived from the hemp seed, which is a part of the cannabis plant (marijuana). The oil is rich in essential fatty acids and antioxidants that may help fight inflammation and other ailments associated with it.
Contrary to popular opinion, the oil does not cause any psychotropic reactions like marijuana. In this post, we will discuss what science says about the health benefits of hemp seed oil.

What Is Hemp Seed Oil? What Is It Good For?
Hemp seed oil is derived from hemp seeds. Though marijuana comes from the same plant, hemp seeds contain just trace amounts of THC (the most active ingredient of marijuana), and they don’t get you high.
The oil is filled with antioxidants and anti-inflammatory agents and other essential fatty acids (like GLA), all of which are known to combat diseases like inflammatory arthritis, cancer, diabetes, and heart disease.
What Are The Benefits Of Hemp Seed Oil?
1. May Fight Inflammation
Hemp seed oil is rich in GLA (gamma linoleic acid), which is an omega-6 fatty acid that may boost immunity and fight inflammation.
However, both animal and human studies still need to conclude how effective the anti-inflammatory properties of hempseed could be (1).
The oil is also a good source of anti-inflammatory compounds, which may help relieve arthritic symptoms. More research is required to study its anti-inflammatory effects.
Hemp seed oil, when taken along with evening primrose oil, was found to improve symptoms in individuals with multiple sclerosis (which can be caused by inflammation) (2). Experts theorize it might also help in the treatment of fibromyalgia.
2. May Boost Heart Health
A meal containing hempseeds was found to help prevent high cholesterol levels. The results could be attributed to the polyunsaturated fatty acids in the seeds. These seeds (and their oil) could show potential in the treatment of cardiovascular disease (3).
As per an animal study, hemp seed oil was found to reduce cholesterol absorption. Another study states that taking 30 mL of the oil every day for four weeks reduces the ratio of total cholesterol to HDL cholesterol (4). This may promote heart health.
It also is thought that in addition to the fatty acids, certain other bioactive compounds found in hemp seed oil may also help in this regard. The oil has omega-6 and omega-3 fatty acids in the optimal ratio – 3:5:1 to 4:2:1, which seems to satisfy the modern standards of healthy nutrition (5).
3. May Aid Diabetes Treatment
Diabetes is also linked to an unbalanced intake of essential fatty acids. As hemp oil is rich in essential fatty acids, it may work as a good supplemental treatment (6).
However, we need more research before we conclude that hemp seed oil can benefit diabetes. Please consult your doctor before using the oil for this purpose.
4. May Help Reduce Cancer Risk
The tetrahydrocannabinol in hemp seed oil may help inhibit certain forms of cancer. Most animal studies have shown the tumor-inhibiting action of tetrahydrocannabinol (7).
However, we need more additional trials to understand the antitumor effects of tetrahydrocannabinoland hemp seed oil (7).
Other studies have shown that cannabinoids derived from hemp seeds may aid in the treatment of cancers of the lung and breast (8).
The GLA and omega-3s in hemp oil may also help, but we need more research to confirm the findings.
5. May Improve Brain Health
The hemp seed oil contains cannabinoids. Studies show that these may help ease anxiety in those with a social anxiety disorder (9).
Studies also support that inhalation of hemp essential oil can have a relaxing effect on the nervous system. Inhaling the oil (aromatherapy) is believed to enhance the mood. There is a possibility that the oil may also have antidepressant effects (10).
The essential fatty acids in the oil may also improve memory and prevent age-related cognitive decline. Further studies are warranted to arrive at a conclusion.
6. May Boost Immunity
The oil contains omega-3 fatty acids. Some research shows that omega-3 fatty acids may boost immunity and enhance protection against infections and other related ailments (11).
7. May Be Beneficial During Pregnancy
Hemp seed oil is also a great option for all pregnant mothers. Again, a major part of the credit goes to the omega-3 fatty acids.
According to an American study, adequate intake of omega-3 fatty acids is critical during pregnancy as they are the building blocks of the fetal brain and retina. They also play a major role in preventing perinatal depression (12).
Oils containing omega-3 fatty acids can also help prevent preterm delivery and promote an easier birth and the baby’s optimum lifelong wellness (13).
However, there is less information available on the safety of hemp seed oil during pregnancy. Also, whether the omega-3 fatty acids in the oil would benefit during pregnancy is still a matter of debate. Hence, we recommend you consult your doctor.
8. May Enhance Digestive Health
Direct research on the efficacy of hemp seed oil on promoting digestive health is lacking. However, the EPA and DHA (in the omega-3s in the oil) were found to synthesize compounds called eicosanoids (14).
Some experts believe that these eicosanoids may regulate the secretion of digestive juices and hormones, thereby aiding the overall digestive process. However, sufficient research is lacking in this regard.
It also is believed that the small amount of protein in the oil is identical to the one present in our blood, which may help in alleviating digestive troubles (as the protein gets easily digested in the human body). More studies are warranted to establish this theory.
9. May Be Useful For Skin Care
Hemp seed oil can help you get beautiful and healthy skin. It acts as a moisturizer and prevents your skin from becoming dry during the winters (15). In other words, it keeps your skin soft, fresh, and hydrated.
You can try applying hemp seed oil all over your body after taking a bath. You will notice the difference in a few days. However, we suggest you do a patch test first as anecdotal evidence suggests that hemp seed oil may cause allergies.
Some sources suggest that the oil does not clog your pores. Its linoleic acid may regulate sebum production. Lack of linoleic acid in the diet can provoke the sebum to clog our pores, which gives rise to blackheads, whiteheads, or acne lesions. In fact, those with acne had decreased concentrations of linoleic acid on the skin surface (16). You can wet your face, pat it dry, and apply the oil to the affected areas. Massage properly. Use it once a day.
You can use hemp seed oil in a similar way to removing makeup.
10. May Protect Skin From Disease
Dietary hemp seed oil may be used to treat atopic dermatitis. Studies attribute this therapeutic effect to the polyunsaturated fatty acids in hemp seed oil (17).
The essential fatty acids in the oil act may as an internal moisturizer, helping relieve eczema symptoms. Taking the oil thrice a day, along with applying it to the affected areas on the skin, could be beneficial. But since solid research is lacking in this regard, consult your doctor before using the oil for eczema treatment.
Using the oil every day for 20 weeks was also found to relieve the symptoms of dermatitis. This is especially true with the itching associated with the condition (17).
Some believe that the oil may also help relieve shingles, which is one type of rash. Anecdotal evidence suggests that hemp oil may reduce the inflammation and even protect the nerve cells (that are usually attacked in this condition). Consuming hemp oil could help you deal with the symptoms of pain, though more research is needed here.
But since each case of shingles could be unique, we suggest you talk to your doctor and take their advice on the way you need to use hemp oil to treat your condition. There also is limited research in this area. Hence, talking to your doctor should help.
Hemp seed oil may also be used to prevent sunburns. Some believe adding zinc oxide to the oil can boost its SPF rating (from a rating of 6). However, there is no research to support this. The oil could be one great way to soothe a sunburn as it is believed to protect the delicate layers of the skin.
Insufficient evidence for the following
11. May Aid Weight Loss
Studies have shown that individuals taking GLA supplements for a year gained back less weight (19). Since hemp oil is rich in GLA, it may also help in this aspect. However, there is no research supporting this statement.
The omega-3s in hemp seed oil may also contribute to weight loss in some way. But there is very little research to support this. Hence, it is important you talk to your doctor before using hemp seed oil for this purpose.
12. May Help Relieve PMS Symptoms
GLA may help ease menstrual cramps. Studies show that supplementation with fatty acid may not cause any side effects (20).
Anecdotal evidence also suggests that hemp seed oil may help treat breast tenderness, feelings of irritability and depression, and swelling. There is no research to support this, though.
13. May Boost Hair Growth
The healthy fats in hemp seed oil are believed to add moisture and shine to hair. The oil is also thought to strengthen fragile hair strands and can make your hair thicker. It may promote new hair growth as well.
Using the oil on the scalp, as per anecdotal evidence, may also reduce several scalp problems, including itchiness, dryness, and dandruff. The oil may also aid the treatment of scalp psoriasis.
These are the different ways hemp seed oil can benefit you. Knowing its nutritional profile can help you understand the benefits better.

Now, we get to one important question – is hemp seed oil legal? Given that it is a cousin of marijuana, and marijuana is not yet legalized in several parts of the US, is it legal to use hemp seed oil? Are you breaking the law while buying hemp products?
Is Hemp Seed Oil Legal?
According to a report by the United States Drug Enforcement Administration, hemp and marijuana are separate parts of the species of the cannabis plant (21). Under federal law, the focus of the government falls on those parts of the cannabis plant that are the sources of THC (tetrahydrocannabinol), the hallucinogenic substance in marijuana that causes people to get high.
Hemp does contain THC. Though it is present only in trace amounts and doesn’t get you high, it still does contain THC – and as per the rulebook, that’s a problem.
The good news is that most manufacturers who market hemp seed oil ensure there is no THC. Hence, the best way to go about it is to check the ingredients listed on the product labels. If there is no THC, you are good to go. Otherwise, go for a different manufacturer or take the advice of the store owner.
Some reputable brands of hemp seed oil that you don’t have to worry about include Nutiva and Canada Hemp Foods.
Hemp seed oil also has some side effects.
What Are The Side Effects Of Hemp Seed Oil?
- Interaction With Blood Thinners
Hemp seed oil can slow down blood clotting and lead to bleeding. Though there is no direct research, one study states how cannabidiol can interfere with warfarin (a blood thinner) (22). Hence, don’t use it if you are taking blood thinners or have a surgery scheduled within a month.
- THC Effects
Though highly unlikely, you may experience hallucination or euphoria on consuming the seeds/oil (23). To avoid this, you may want to get into the habit of checking the product labels and go only with trusted brands.
- Digestive Issues
Research is limited in this aspect. This could be true with the seeds and not the oil. The high fiber content might lead to constipation, gas, or diarrhea (when you quickly increase your fiber intake and don’t drink enough water).
As hemp seed oil belongs to the same family as marijuana, its availability and legality could be a problem at times. However, if you procure it from the right vendors, you should not have a problem.
More research is needed to validate some of the popular benefits of hemp seed oil. While there may not be a major risk of using this oil (sparingly), we suggest you check with your doctor before you do so.
