THE ULTIMATE GUIDE To CBD HEMP OIL
Industrial hemp is as a class of non-drug Cannabis sativa varieties, and hempseed is technically an achene, or nut. Both the seed and hemp's tall stalk provide significant carbohydrate feedstocks for a wide variety of industrial purposes in several countries. The oil pressed from hempseed, in particular, is a rich source of polyunsaturated omega-3 and omega-6 fatty acids, which are essential for human health.
These same fatty acids in hempseed oil make it a fine drying oil that is used in the production of paints, varnishes, and other coating materials. Plastic flooring such as linoleum and similar materials have been made from hempseed oil, and other non-food uses of hempseed oil are similar to those of linseed oil flaxseed oil. Flax, of course, also has a long history as a companion species that parallels hemp in the founding of our civilizations.
Unfortunately, when one reads the Latin words Cannabis sativa these days, the first thoughts that come to mind may not be of hemp, or its nutritious seed, or useful oil products, or even the durable outer bast stem fiber or the cellulose core from the stalk of this old-world plant.
These lesser-known features of Cannabis were certainly well known to Carl Linneaus when he assigned its name in The words " canvas " and " cannabis ," for example, both derive from similar-sounding words in Greek, Latin, and Arabic for the fabric and the plant from which it is made. The second part of the Linnean binomial, sativa , comes from the Latin word sativus , which means "sown" or "cultivated. The largest obstacle that currently prevents hemp from fully participating in modern industrial agriculture is its botanical association with the drug cannabis.
In fact, the production of THC tetrahydrocannabinol and other cannabinoids is under genetic control, so it would take an ambitious breeding project to convert a hemp variety into a drug variety, much like converting a dachshund into a Doberman pinscher. In other words, it would be much easier just to start with drug Cannabis seeds, if that were the objective.
Ancient Asian mariners and more recent trans-Atlantic voyagers made good use of sturdy canvas sails made from hemp fiber. Fine linens were once made from both flax and hemp, as the fibers from the male hemp plants were well known to produce the finest linens.
The oldest known paper from China was made from hemp, and many historical documents have been written and printed on paper made from hemp fibers. Even today, hemp fibers are found in such common products as tea bags, cigarette papers, and other specialty papers as well as paper currency.
The connection between Cannabis and its misuse as a drug gained official traction when the US Congress passed the Marihuana Tax Act on June 14, ; the Act included no practical exemption for hemp production. By that time, the United States was already importing most of its hempseed and fiber from countries with cheaper labor, and the timber and paper industries in the United States were completely invested in the Kraft process for making newsprint.
In , commercial wild bird feed was primarily made from hempseed, and hempseed was also pressed for oil used in the manufacture of paints, varnishes, and other coatings. Industrial-scale hemp production mostly continued in the USSR Union of Soviet Socialist Republics and China until modern petroleum products slowly began to replace products previously made from hempseed oil and hemp fiber. At least in the days of the USSR, hempseed oil for human consumption was called "black oil," because of its high chlorophyll content, which was especially used by those who were too poor to afford butter.
Hempseed appears as an ingredient in many spices and ethnic foods from Eastern Europe, India, and most parts of Asia. A fine tofu can be easily made from just hempseed, water, and heat. The Marihuana Tax Act of had very little impact on the use of marijuana as a narcotic in the United States, if for no other reason than the Act did not penalize the possession or use of hemp, cannabis , or marijuana.
It did, though, penalize persons dealing commercially in these products. Thus, the Act effectively brought all industrial hemp production in the United States to a grinding halt by the next year. Subsequently, the United States re-introduced hemp production in for the war effort, after the Japanese had cut off hemp supplies from the Philippines and East India.
After the war, US hemp production was shut down yet again. Petroleum-based polymers quickly replaced hemp and other natural fibers in many common products such as sacks, tarps, and ropes. In just a short time, a carbohydrate culture based on agriculture quickly shifted into a culture dependent on petroleum-derived hydrocarbons.
Since then, hempseed and hemp fiber production have been excluded from the technological developments enjoyed by other industrial crops. Nor have there been any advances in nutritional research pertaining to hempseed oil. This prohibition on hemp cultivation continues to this day in the United States, even as remarkable advances are being made with medical marijuana.
In Canada marijuana is already available to registered patients for medical purposes. After years of prohibition, hemp cultivation was cautiously restarted there under heavy licensing in With eager markets in both Canada and the United States, hempseed oil and other hempseed food products remain in high demand, and the area devoted to oilseed hemp cultivation in Canada has continued to expand accordingly during this time. The Finola oilseed variety of hemp continues to form the cornerstone of the Canadian hempseed production because of its short stature average plant height: 1.
Hempseed is a rich source of easily digestible protein ca. The remainder consists of dietary fiber, mostly from the hull, various phytosterols, oil-soluble vitamins, and trace minerals Table 1. Aside from being extremely low in saturated fats, hempseed oil is interesting in other ways.
For example, hempseed oil has a higher content of polyunsaturated fatty acids PUFA than most other industrial food oils Table 2. This has been known for quite a long time, as the essential omega-6 linoleic acid n-6 was first identified in hempseed oil as "sativic acid" by German chemists in More recently, presence of omega-3 stearidonic acid SDA, n-3 has been detected in hempseed oil Callaway et al. Not only are both of the essential fatty acids EFA well represented in hempseed oil, but their direct human metabolic products, GLA and SDA, are too; the latter are not found in any other industrial oilseed crop.
As these two fatty acids are already in the oil, this enzymatic step can be bypassed, so they contribute more directly to the downstream production of other omega-6 and omega-3 metabolites.
Perhaps the really good news for consumers is that good-quality cold-pressed hempseed oil has an excellent taste that resembles walnuts and sunflower seeds. When the seeds are toasted, a savory umami flavor develops somewhere between that of bacon and fried prawns.
Moreover, the balance of EFA in hempseed is considerably more nearly optimal than in most other industrial food oils, in terms of having a relatively low omega-6 to omega-3 ratio. In this regard, hempseed oil is more like rapeseed oil also known as canola oil , yet it is still much higher in polyunsaturates. Taken together, these factors at least partly explain a remarkable number of anecdotal benefits from consuming daily hempseed oil, for example, especially marked improvements in skin, hair, and nail quality, as these fatty acids are integral in cell membrane formation and functions at the molecular level.
Studies at the University of Kuopio, Finland, have investigated some of the properties, and particularly the improvements in skin quality for patients that suffer from atopic dermatitis i.
Improvements in strength of both hair and nail thickness are also attributed to daily use of dietary hempseed oil. The high level of PUFA in hempseed oil is certainly a plus for health, but a considerable drawback for deep frying, not only because there is an increased risk of peroxide and trans fat formation, but also because hempseed oil has a relatively low flash point and will burn well once it is ignited.
Also, the shelf life of hempseed oil tends to be rather short, because this high level of unsaturation provides more opportunity for oxidation with atmospheric oxygen. Ideally, as a food, hempseed oil is cold pressed from fresh, clean, good-quality seed and then stored in a cool, dark place before, during, and after processing. Unfortunately, much of the hempseed oil that is currently available in North America is distributed in plastic containers to reduce the costs of both production and shipping of this niche crop.
Oil purchased in plastic is more susceptible to degradation with time. With a small amount of effort, the interested buyer will typically find hempseed oil in glass bottles on the European markets. To this day, the US government continues to define hemp as the stalks and fiber of the marijuana plant, and has decided not to recognize any of the varieties that are extremely low in drug content.
An analogous situation exists for poppy seed, which is legal in the United States; the seed always contains some measurable amount of morphine, but these amounts are not of sufficient concentration for drug purposes. Due to the burden of Cannabis prohibition, there has been very little development or innovation in hemp or hempseed production during the last 70 years, and almost no research on hempseed nutrition since its incorporation into Chinese medicine thousands of years ago.
It is, in essence, an orphan crop when we consider the present situation of food production in Europe and North America. While this situation began to change with the reintroduction of hemp to Canadian agriculture in , the subsidy scheme for hemp in the European Union continues to favor the production of hemp fiber and not hempseed.
What few results we now have from hempseed research tend to contradict the politically narrow horizon that the United States has offered the world. Fortunately, hempseed oil and other hempseed food products are legally available in the United States, either from the shelves of some natural food stores or when ordered directly online from Canada. Viable hempseed, however, remains illegal in the United States.
Leaving political rhetoric aside, there is plenty of convincing scientific evidence to show that hempseed is one of the most nutritious products that can be produced by modern industrial agriculture. As a grain, it fits into the mechanized infrastructure without retooling. Apparently, the only remaining change that needs to be made is to convince US policymakers that hemp is not dangerous.

Apparently CBD Is “Natural” – What Does That Really Mean? Hemp seed oil, also sometimes called “hemp oil”, is derived from the seeds of.
Tetrahydrocannabinol THC , along with cannabidiol CBD are two of many chemical compounds naturally present in the cannabis plant. Hemp and marijuana both come from the cannabis sativa plant, but cultivars of the plant are bred for specific purposes. Hemp plants are bred to have as little THC as possible and are used in many industrial applications. Hemp oil comes from the stalk and seeds of the plant, unlike marijuana which comes from the flowers or buds.
Compared to whole plant CBD -rich cannabis, industrial hemp grown for fiber or seed is typically low in cannabinoid content.
As the name suggests, hemp oil comes from the hemp plant. However, hemp oil is more complex than it appears on paper.
Are Hemp Oil and CBD Oil the Same Thing?
There is a lot of excitement about hemp oil these days. There is also a lot of confusion. Or whether or not it contains THC, the psychoactive ingredient in marijuana. If you use a hemp oil supplement are you breaking any laws? The following are answers to some of the most frequently asked questions about hemp oil.
Hemp seed oil vs. CBD oil: Two totally different things—here’s what to know
CBD is just something that I am very happy about that I can be a part of. I mean imagine it being 30 years ago when no one knew much about it. We are so lucky guys. It helps me sleep. I seem more relaxed not drunk or groggy and I do not feel "foggy" when I awake. I sleep deeper and so good. I take half a dropper of oil mg. I have a busy Health Center, with a variety of health services we offer.
Consumers looking to explore the potential benefits that cannabidiol CBD promises are often confronted with some confusion when it comes to terminology. Often housed in 1-ounce glass bottles, CBD oil products can list a variety of names on the label.

Hemp Oil vs. CBD Oil: What You Should Know
CBD oil is made from the leaves, flowers and stalks of the hemp plant—the only parts of the plant where cannabidiol is found. Hemp oil, or hemp seed oil, is made from hemp seeds, meaning there is little to no CBD content. Each type of oil offers its own potent health benefits. The best way to determine if a product is CBD oil or hemp oil is to look at the ingredients listed on packaging. Hemp oil is often looked to for its nutritional power, due to its healthy fats and mineral content. There have also promising studies on its effect on skin disorders and PMS symptoms. Hemp seeds are rich in essential fatty acids like linoleic acid omega-6 and alpha-linolenic acid omega They are also an excellent source of protein and offer vitamin E and other health-enhancing minerals, such as phosphorus, potassium, sodium, magnesium, sulfur, calcium, iron and zinc. Studies have shown that giving hemp oil to those with eczema may improve symptoms of the skin disorder, including dryness and itching. Hemp is a good source of GLA gamma linoleic acid , which has been shown to decrease the inflammation that can occur with menopause. Hemp oil has also been found to alleviate symptoms of PMS , which can reduce the effect of the hormone prolactin in the body. CBD is sought for its range of health benefits , which include relief from pain, inflammation and insomnia. In a study of patients with arthritis, CBD effectively reduced pain, stiffness and inflammation. In another study of those with multiple sclerosis, patients experienced improvement in pain reduction, walking and muscle spasms when taking CBD.
What is Hemp Oil Made From?
Hemp oil hemp seed oil is oil obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavor. The darker the color, the grassier the flavour. It should not be confused with hash oil , a tetrahydrocannabinol -containing oil made from the Cannabis flower. Refined hemp seed oil is clear and colorless, with little flavor.
