Hemp Seed Oil: Properties and Benefits
Hemp seed oil is a vegetable oil rich in essential fatty acids which is obtained by cold pressing Cannabis sativa seeds . The Cannabis sativa fruit contains only one seed in its achene and the extraction of hemp seed oil can take place in different ways: extraction with solvents or pressing, depending on the use to which it is intended.
Usually hemp oil has a greenish color, it is almost odorless but on the other hand it has a very pleasant taste reminiscent of toasted hazelnuts. Hemp seed oil is used as a bio-fuel if it is burnt inside biodiesel engines, it can be used in cosmetics for its emollient and antioxidant properties, it can be used as a drying substance to be used in paints and obviously it is use in the food industry.
Currently, hemp seed oil is the subject of numerous scientific studies aimed at demonstrating the benefits it can have in human nutrition . Hemp oil is not the only product of this plant that is used in human nutrition, in fact hemp flour has recently become very popular both in baking and in vegan and vegetarian nutrition.
What are the properties of hemp seed oil?
Hemp oil is a vegetable oil very rich in unsaturated fatty acids and boasts important properties: immunomodulating, anti-inflammatory and antioxidants which are still being examined by the scientific community today. Specifically, hemp seed oil has a large amount of alpha-linolenic acid, a ω-3 fatty acid, comparable to that found in flaxseed oil and fish oil.
The quantity of ω-3 fats supplied by this oil compared to that of ω-6 fats is acceptable (3:1) if we consider that most vegetable oils tend towards the latter. Many scientific studies show that an excessive intake of ω-6 in the diet, compared to ω-3, increases the possibility of manifestation of some inflammatory diseases and cardiovascular risks.
Therefore, it is always recommended to balance the content of these two fats by varying the diet and increasing the sources of ω-3 fats by choosing from those in which it is more present or by resorting to specific food supplements . Hemp seed oil also contains many amino acids and vitamins such as vitamin A , vitamin E and a good source of vitamin B1 , vitamin B2 and vitamin C .
The qualitative study conducted on hemp oil has demonstrated the presence of cannabinoids inside it and in particular cannabidiol which seems to perform important functions of strengthening the immune defenses. While, the amazing component of Cannabis , tetrahydrocannabinol ( THC ) is present in infinitesimal percentages in hemp seed oil , so much so that to manifest psychotropic effects it is necessary to take almost 9 liters of hemp oil a day. For this reason, the use of hemp oil is safe from this point of view.
How to take hemp oil ? A healthy consumption of hemp oil involves taking 3 tablespoons a day and must be consumed strictly raw. In fact, hemp oil has a very low smoke point and for this reason it cannot be used for prolonged cooking or frying.
If the smoke point is exceeded during frying, carcinogenic substances such as acrolein are formed and this applies to all oils, not just hemp. The properties attributed to the use of hemp oil are many and many are still the subject of discussion within the scientific community regarding their effective validity.
Hemp seed oil may be beneficial in the treatment of arthritis, osteoarthritis and muscle pain, rheumatoid arthritis and Crohn’s disease. It is used in case of hypercholesterolemia and hypertriglyceridemia, asthma, tracheitis, sinusitis, contact dermatitis, cold sores , sunburn. It is used as a hepatic and gastrointestinal protector and seems to be an excellent remedy for reducing the disorders associated with premenstrual syndrome and climacteric.
Does hemp oil have contraindications?
Hemp seed oil is a food that can be consumed by anyone, except those people who can show a specific hypersensitivity reaction to one or more substances present in it.
As for the presence of the active psychotropic constituent, THC , there is absolutely no need to worry because the quantity present is really very low to create addiction problems or cause psychotropic effects.
However, it should be borne in mind that taking hemp oil could distort anti-doping and anti-drug controls because these tests are very sensitive even to the smallest concentrations present. Therefore, if you practice sports at a competitive level, it is good to have an appropriate medical prescription available that justifies its use.
