hemp seeds for pain relief

Hemp seeds also contain phytosterols, which help in reducing the amount of cholesterol in the body by removing fat build-up in the arteries.

What are the health benefits of hemp?

Hemp seeds have a mild, nutty flavor. Hemp milk is made from hulled hemp seeds, water, and sweetener. Hemp oil has a strong “grassy” flavor.

Hemp is commonly confused with marijuana. It belongs to the same family, but the two plants are very different. Marijuana is grown to contain high amounts of tetrahydrocannabinol (THC), the chemical that is responsible for its psychoactive properties. Hemp describes the edible plant seeds and only contains a trace amount of THC.

This feature is part of a collection of articles on the health benefits of popular foods. It provides a nutritional breakdown of hemp and an in-depth look at its possible health benefits, how to incorporate more hemp into your diet and any potential health risks of consuming hemp.

Nutritional breakdown of hemp

According to the USDA National Nutrient Database, a 2 tablespoon serving of hemp seeds weighing 20 grams (g) contains:

  • 111 calories
  • 6.31 g of protein
  • 9.75 g of fat
  • 1.73 g of carbohydrates (including 0.8 g of fiber and 0.3 g of sugar)
  • 14 milligrams (mg) of calcium
  • 1.59 mg of iron
  • 140 mg of magnesium
  • 330 mg of phosphorus
  • 240 mg of potassium
  • 1.98 mg of zinc
  • 22 micrograms (mcg) of folate

Hemp seeds also provide vitamin C, some B vitamins, and vitamins A and E.

Possible health benefits of consuming hemp

The nutritional content of hemp is linked to a number of potential health benefits.

Healthy fats

The American Heart Association recommends consuming two 3.5-ounce servings of fish, especially oily fish, each week. This is because fish is a major source of omega-3 fatty acids. If a person does not regularly consume fish, they may not be getting enough DHA or EPA.

Hemp is a plant-based source of concentrated omega-3 fatty acids. However, the fatty acids that hemp contains are alpha-linolenic acids (ALA), which are poorly converted to DHA and EPA in the body at a rate of only about 2 to 10 percent.

Despite this inefficient conversion rate, hemp is one of the richest sources of ALA, and so still represents a very good source of healthy fat, particularly for those who do not consume fish or eggs.

Hemp contains a specific omega-6 fatty acid called GLA and hemp oil contains an even higher percentage of GLA.

Hemp seeds also contain phytosterols, which help in reducing the amount of cholesterol in the body by removing fat build-up in the arteries.

Protein source

Hemp contains all 10 essential amino acids, making it a good plant-based protein source. Hemp does not contain phytates, which are found in many vegetarian protein sources and can interfere with the absorption of essential minerals.

Hemp oil benefits list

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 health

The 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:

These benefits are likely to be due to the high quantity of beneficial fats and other helpful compounds in the oil.

Brain health

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.

A recent study in 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.

Heart health

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.

An older study in the journal Nutrition & Metabolism highlights the nutrient profile of hemp seeds and notes that they might have a positive effect on various health issues, such as high blood pressure, atherosclerosis, and cholesterol levels.

A 2014 review concludes 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 in fish oils and flaxseed oil. However, the researchers call for more clinical trials to confirm these results.

Full-spectrum hemp oil benefits

Full-spectrum hemp oil also includes plant matter, which adds additional compounds, such as CBD.

Although hemp seeds contain small amounts of these compounds, a higher concentration may bring some additional benefits to the body.

Natural pain relief

Many people use hemp or CBD oil as a form of natural pain relief, especially if the pain is a result of inflammation.

Those who do not want to take over-the-counter or prescription pain medications may turn to a high-quality hemp oil for relief.

A 2018 review notes that CBD, one of the main compounds in full-spectrum hemp oil, and other cannabinoids show promise for the treatment of many types of pain.

However, most of the research to date is on mice.

While the current research suggests that CBD may be a helpful natural treatment for pain, more human studies could give these results more credibility.

The fatty acids in hemp seed oil may help balance the skin and prevent inflammation that can result in acne. The addition of CBD from the plant matter may also help clear acne.

A study in the Journal of Clinical Investigation found that CBD may affect the sebum glands in people with chronic acne, leading to reduced sebum production and potentially helping clear or prevent acne breakouts.

Muscle tension

Full-spectrum hemp oil that contains CBD may also help with general stress and tension in the muscles.

Like fatty acids, CBD has an anti-inflammatory effect on the body, which may help relieve the tension that many people carry from stress and promote recovery from exercise.

Rubbing a bit of hemp seed oil or full-spectrum hemp oil into tight muscles may help release tension and relax them.

Takeaway and future research

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 a 2017 study show 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.
