The many health benefits of hemp seed oil come from its high content of three polyunsaturated fatty acids: linoleic acid, alpha-linolenic acid, and gamma-linolenic acid. Additionally, its ratio of omega-6 (linoleic acid) to omega-3 (alpha-linolenic acid) fatty acids is 3:1.

Although hemp seed oil offers many health benefits, it’s important to be aware of the potential risks.
To avoid interactions, tell your doctor and pharmacist about all prescription, over-the-counter, herbal, or recreational drugs you are taking.
The tricky part is calculating the exact amount of CBD per milliliter of oil. Some tinctures have concentrations of 1,500 mg per 30 mL, while others have 3,000 mg per mL (or more).
Medical marijuana is frequently prescribed to people with intractable (treatment-resistant) pain, including those with terminal cancer. There is some evidence that CBD contributes to this benefit.
Dosage and Preparation
CBD shows promise in the treatment of anxiety disorders, suggests a 2015 review of studies in the journal Neurotherapeutics. According to the investigators, CBD demonstrated potent anxiolytic (anxiety-relieving) effects in animal research, albeit with counterintuitive results.
CBD oil may also increase liver enzymes (a marker of liver inflammation). People with liver disease should use CBD oil with caution, ideally under the care of a doctor who can regularly check blood liver enzyme levels.
CBD oil should be avoided during pregnancy and breastfeeding. A 2018 study from the American Academy of Pediatrics warned women to avoid marijuana during pregnancy due to the potential risks to a baby’s development. Although it is unclear how CBD contributes, CBD is known to pass through the placental barrier.
Outside of these two disorders, CBD’s effectiveness in treating seizures is uncertain. Even with Epidiolex, it is uncertain whether the anti-seizure effects can be attributed to CBD or some other factor.

Over time, excess inflammation in your body can contribute to a variety of diseases including heart disease, diabetes, cancer, and asthma. It has been suggested that gamma linolenic acid, an omega-6 fatty acid found in hemp, acts as an anti-inflammatory. Studies have also linked the omega-3 fatty acids in hemp with reductions in inflammation.
Potential Risks of Hemp Oil
Many of these nutrients provide the body necessary minerals and also contribute to overall health. Note that hemp seeds contain a significant amount of iron (20 % of your recommended daily diet). This helps prevent iron deficiency, or anemia.

It’s possible that ingesting CBD-containing oils like hemp oil can cause an upset stomach or diarrhea. Again, when you’re first introducing hemp oil into your diet, start small to see how it impacts you. Reactions may be different from person to person.
Some people experience skin irritation when using topical oils containing CBD, possibly due to an allergy. Start with using a small amount to see how your skin reacts to it, and keep an eye on any changes.
