Due to its polymer-forming properties, hemp oil is used on its own or blended with other oils, resins, and solvents as an impregnator and varnish in wood finishing, as a pigment binder in oil paints , and as a plasticizer and hardener in putty. It has uses similar to linseed oil and characteristics similar to tung oil.

Other studies suggest administration of EFAs and GLA as preventive measure and a treatment for multiple sclerosis, schizophrenic psychosis, and cancer. Multiple sclerosis occurs more frequently in geographical regions where the diet includes high amounts of saturated fats. Dietary supplementation of unsaturated fatty acids may have a positive effect on the course of the disease. In patients with schizophrenic psychosis disturbances are found in the fatty acid metabolism which might be treated through administration of essential fatty acids.
Cancer treatment may be assisted by administration of linoleic acid and GLA. Cancer tissue and cells have lower contents of GLA and other related metabolites compared to healthy tissue. Linoleic acid enhances die-off of cancer cells. Administration of this essential fatty acid might therefore prove to have positive effects. Hemp oil used in the kitchen provides as much of the EFAs as necessary — in the right composition.
The table shows the GLA and linoleic acid content in hemp oil in grams and teaspoons and allows you to determine desired dosages. As the GLA content in hemp oil may vary refer to product label , so may the amount of oil required to achieve a certain dose. The increasing popularity of hemp oil in cosmetics is also largely due to its high EFA content.
Facial creams, body lotions, soaps, lip balm, shampoo and conditioner, massage oil with hemp oil are just some of the available products. As a natural ingredient in the formulation of cosmetics, hemp oil provides the following benefits: The emollient, lubricant, and moisturizing properties of EFAs are well established. Although true EFA deficiency in humans is a rare condition, cosmetic skin problems such as scaling or dry, cracking skin also respond cosmetics containing EFAs.
The slow-down with age in the metabolism of cells in the basal layer of the epidermis also reduces the amount of EFAs released into the epidermis. This age related decline in activity is a major contributor to the above mentioned detrimental effects to the skin, thus contributing to the formation of wrinkles and overall skin aging.
Topical application of EFAs partially compensates for their decline in the skin and the obvious effects of aging. Even when grown conventionally, hemp farming does usually not involve the use of pesticides and herbicides. Rather, it provides additional agricultural benefits, such as suppression of weeds and pests. This compares favorably to evening primrose and borage, specialty cultures which are sensitive to pests and weeds and require, unless grown organically, the use of synthetic chemicals.
Many plant oils naturally contain unsaturated fatty acids. Unfortunately, a high content in polyunsaturated fatty acids, such as in hemp and flax oil, increases the tendency of an oil to become rancid, especially when exposed to oxygen, light, and elevated temperatures. Rancidity results from the breakdown of fatty acids causing formation of rancid tasting and unhealthy compounds, such as aldehydes.
Most edible oils on supermarket shelves have been treated by mechanical and chemical refining processes to increase their shelf-life, enhance clarity and remove other undesirable compounds. The latter may result from poor seed quality or from the extraction process.
Commercial oil making may include any or all of the following steps: Margarines, shortenings, and shortening oils for example are hydrogenated — or hardened — which removes unsaturated fatty acids, including the essential fatty acids.
During the refining processes aroma and flavour as well as valuable compounds, for example vitamin E, lecithin, and minerals are removed. Trace amounts of solvents may be present, preservatives added, and some of these processes may even result in the formation of unhealthy by-products, for example trans-fatty acids from hydrogenation, or hardening, of oils. Until recently, almost all oils on supermarket shelves used to be solvent extracted and fully refined.
In fact, they also reflect the trend towards oils with a higher content of unsaturated fatty acids, i. Yet, they are bland and are missing valuable ingredients and character. No wonder cold pressed oils olive, walnut, safflower, pumpkin are increasingly gaining shelf space. Mechanically cold-pressed not solvent extracted , unrefined oils have the characteristic aroma and flavour of the seeds from which they were pressed.
Hemp oil for example has a delicate, nutty flavour. Unrefined oils still contain most of the vitamins, other antioxidants and minerals present in the seeds. These oils generally also have a high content of unsaturated fatty acids which increases their tendency to become rancid and thus reduces their shelf-life.
To make the most of the natural and healthy ingredients of these oils, they should be consumed fresh. Unrefined, cold-pressed oils — such as hemp oil — are routinely pressed and bottled in a nitrogen atmosphere and sold in tinted or dark bottles to protect them from light. After opening they should be stored in the refrigerator and consumed within six months.
Health agencies and media routinely raise the question: Even hemp oil from European or Chinese low-THC varieties of industrial hemp routinely contains traces of THC, though too low to cause any noticeable effects. This suggests that THC in hemp oil usually does not pose the risk of involuntary intoxication or other health risks.
Health Canada has set a more conservative limit of 10 ppm which many imported oils may fail to meet. However, there are several ways to further reduce the THC content of hemp oil and other foods from hemp seeds. Hemp seeds themselves do not contain THC.
Rather, it is present in the flowers and their sticky resins may leave traces of THC on the seeds. It comes as no surprise that thorough cleaning of the seeds, or even de-hulling, and the use of varieties with a very low THC-content have proven effective in reducing THC levels in oil to less than 5 ppm. Hemp oil producers now increasingly turn to these methods. To provide guidance to decision makers, the nova institute recently suggested THC limits for various food products.
They provide a wide margin of safety from psychoactive effects and can be met as long as seeds are properly cleaned and low-THC varieties are used.
Hemp oil can be legally imported or pressed in Europe, and from imported, sterilized seeds in the USA and for external use only in Australia.
The meat of hemp seed does not contain the drug tetrahydrocannabinol THC , which is the psychoactive substance in marijuana. Minute amounts of THC may be transferred from the flowers surrounding the leaves into the oil during pressing. However, these trace amounts are, if seeds from low-THC varieties are used and properly cleaned, too low to have any psychoactive effects.
Unrefined hemp oil — just like olive oil — should not be used for high temperature or deep-frying. At high temperatures, unhealthy oxidation and polymerization products are formed from the unsaturated fatty acids. Furthermore, at temperatures approaching F, undesirable trans-fatty acids are gradually formed.
Flax oil also has a high content in unsaturated essential fatty acids. The ratio of the essential fatty acids three parts linoleic acid to one part alpha-linolenic acid in hemp oil is favourable for the human body because it matches its nutritional requirements.
Flax oil, despite its higher essential fatty acid content, has a less favourable ratio 1: Flax oil also does not contain gamma-linolenic acid, an unsaturated fatty acid, which is found abundantly in hemp oil. To maintain maximum freshness refrigerate after opening and use within six months.

Hemp seed oil is a tasty oil with a green or golden colour crushed from the seeds of the hemp plant Cannabis sativa L. There are four main reasons: Particularly, its attractive fatty acid composition, i. Thus, instead of just being a food supplement, it can serve as a staple food in the modern kitchen.
