Since it is non-toxic and non-flammable, supercritical CO2 is preferable over chemical solvents like butane, hexane, and acetone, which can linger in the extracted oil if not purged correctly, rendering the oil toxic. It has also been noted that botanical essential oils extracted using supercritical CO2 are truer to the scent of the original plants than in other forms of extraction, meaning more of the plant’s chemical structure is retained in the oil with the use of CO2.
After an accident at his workplace that saw Rick Simpson suffer from dizzy spells and tinnitus, Simpson saw a documentary highlighting the positive benefits of using cannabis. He approached his doctor about using cannabis as a treatment, however, his doctor refused. Undeterred, Simpson sourced it for himself. After a short time, he started seeing an improvement in his symptoms and continued to use cannabis as a treatment.
In the United States marijuana is still listed under Schedule I of the Controlled Substances Act. However, the federal Food and Drug Administration (FDA) has authorized clinical trials on a CBD-based drug that treats childhood-onset epilepsy. CBD oil also shows promise in treating intestinal conditions as well as anxiety, post-workout aches, inflammation, and some types of cancers. Additional conditions are neurological inflammation, oxidative injury, and schizophrenia.
Basically, cannabis is an umbrella term that includes both hemp and marijuana plants. Cannabis sativa is actually the scientific name of the cannabis plant (Cannabis = genus; sativa = species), and hemp and marijuana are just two different “varieties” of it (i.e. you could refer to both marijuana and hemp plants as “cannabis” plants, but you would not, for instance, refer to a “marijuana” plant as a “hemp” plant). Hopefully that’s not too confusing.
Recently I asked myself this very question and the more I read the more contradictory statements I found and the more confused I became. With an extensive background in medical marijuana and high THC strains I felt I had a good grasp on which one was “better” before I started researching for this article and could make a good argument for why medical marijuana derived CBD is better than hemp derived CBD. More recently I have been introduced to CBD derived from hemp and after some preliminary research I was not so sure. Fortunately, I have connections from within the industry and so my mission began. I set out to talk to the largest names on both sides of the spectrum and get their opinions on this matter.
To extract, you soak the hemp plant in a solvent, such as grain alcohol. After the material soaks, the remaining liquid contains CBD and the other cannabinoids from the pant. Once you evaporate the solvent, the CBD hemp oil remains. The oil is then ready to either consume or add to edible products. Commercial producers have adopted and modified Mr. Simpson’s method. CBD hemp oil producers use ethanol to extract CBD.
Some work-place drug screens and tests detect THC and not the presence of Cannabinoids or other legal hemp based constituents. However, studies have shown that ingesting hemp can cause confirmed positive results. Based on this information, if you are subject to any form of drug screening or testing or are a member of the United States Armed Services, we cannot recommend that you ingest this product. Please consult with your healthcare practitioner as well as your employer or drug screening company.
Along with its better-known counterpart, THC (delta-9-tetrahydrocannabinol, the chemical that produces the marijuana high), CBD is one of more than 400 compounds found in the oils of cannabis plant species, which include marijuana and hemp. Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, Ph.D., director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”
Healthy folks vaguely looking to add a little spring in their step (via better sleep, reducing anxiety, or easing muscle soreness) drizzle a little oil into their smoothie or latte. They might also spot-treat with a dab of oil in problematic areas. In the past several years, published papers have suggested that the compound can help with a spectrum of medical conditions, including anxiety, Alzheimer’s disease, addiction, arthritis, inflammatory bowel disease, fractures, migraines, psoriasis, and pain. In an animal study, purified extracts of CBD and THC appeared to slow the growth of a type of brain tumor.
There is a strong sedative quality to CBD hemp oil, making it a popular remedy for people with insomnia, sleeplessness, interrupted sleep, post-traumatic stress disorder, restless leg disorder, and other night-time issues. Dr. Scott Shannon, Assistant Clinical Professor of Psychiatry at the University of Colorado School of Medicine, USA, published a report in the Permanete Journal, in which he recommended either inhaling a small amount of CBD oil, applying it to one’s chest, or even putting a few drops on one’s pillow to help get a good night’s sleep.
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.

In terms of how CBD is extracted from the cannabis plant, there a few different techniques that can be used. The most popular used to be by running harsh chemicals like butane (lighter fluid) or hexane over the raw plant material, but people quickly found out that this resulted in trace amounts of carcinogenic compounds (like formaldehyde) being left over in the end product. Not good.
First you need to realize that there are more than 70 different cannabinoids that have been identified so far and over 500 constituents of cannabis including various terpenoids and flavonoids. In fact, the US government holds multiple patents on various cannabinoids. They also hold patents defining these cannabinoids many medical benefits. One of these cannabinoids which has shown a huge amount of potential is CBD or Cannabidiol and while its potential could not possibly be understated there is another cannabinoid making headlines as well. Tetrahydrocannabidiol otherwise known as THC.
CBD is simply an active chemical compound, or cannabinoid, that’s found in the cannabis plant. The reason it’s becoming so popular across such a wide audience of people right now though is because unlike the other main compound in cannabis (THC), it doesn’t get you high. There have been thousands upon thousands of medical studies showing all of the health benefits that CBD has, but “average” people are loving it because it doesn’t produce any mind-altering psychoactive effects.
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.
That being said, though, CBD isolate still has a very relevant place in the cannabis market. A lot of people, for instance, use it to concoct their own personal daily CBD remedies – they mix the pure powder with oil, or they add it into their coffee, or they make edibles out of it. Since it comes in an easily-measurable powder, it’s a great option for those individuals who are trying to calculate exact personal dosages of CBD medication by the milligram.
Another concern is about medications with which CBD might interact. This won’t be an issue with most drugs, says Sunil Kumar Aggarwal, M.D., Ph.D., a palliative medicine physician and scientist who studies cannabis and integrates it into his Seattle medical practice. The exceptions are blood thinners, IV antibiotics, and other drugs whose exact dosing is crucial and must be monitored closely, he says. (Of course, if you have a health problem, talk to your doctor before using CBD, and never take it instead of seeing your physician for a serious condition.)
Essential fatty acids are necessary for maintaining heart and cardiovascular health. The two primary essential fatty acids — Omega 3 and Omega 6 — are ideally consumed at a ratio of around 3:1. Unfortunately, in the typical American diet, that ratio is close to 25:1. Full-spectrum hemp oil offers the two essential fatty acids in the optimal 3:1 ratio.
I think the full spectrum oils are better for medicinal usage. I am suffering from ulcerative colitis, there were more relapses earlier, but I started taking the Purekana CBD oil and now I feel better. Able to stay healthy for longer durations, the vomitings are less severe even during the episode. I had tried some isolates earlier, as my doc is also a kind of genius who keeps on doing his own research, but the full spectrum worked better for my disease. Probably it would go away some day. I am 34 year female and I just weigh 46 Kg at a 5 ft 6inch height!
Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
When extracting a pure botanical oil from hemp, a solvent is passed through the plant material, pulling the compound rich oil from the plant. The solvent is then removed in a purging process, leaving behind a concentrated oil. When extracting from hemp, the oil can next be formulated into finished products or further refined and purified into a number of forms, including a golden dewaxed concentrate or crystallized CBD isolate.
Officially, marijuana is deemed as Schedule I herbal substance by the U.S. Drug Enforcement Administration, meaning the drug offers "no currently accepted medical use and a high potential for abuse," according to the federal government. That categorization was adjusted after the passage of the 2018 Farm Bill, which included a provision that separated hemp from marijuana, as noted in the Controlled Subject Act.
There are thousands of unique varieties of hemp. The cultivars used for CBD oil contain significantly higher concentrations of CBD than others. Using these uniquely potent plants, it is possible to extract cannabis oil that contains significant levels of cannabidiol, as well as essential vitamins, minerals, fatty acids, terpenes, flavonoids, and other non-psychoactive cannabinoids.
