There are a number of potential solvents that can be used to extract CBD oil from the hemp plant. Some companies choose to use dangerous chemical solvents in their extraction process. However, this opens the end user to residual contamination from any solvent that is left unpurged from the oil. To extract our CBD oil from our hemp crops, we use supercritical CO2.
The cannabidiol oil is derived from flowers of cannabis plants and is concentrated in its resin glands or trichomes. These glands contain oil that is rich in CBD which differs in quality and quantity between different strains of the cannabis plant. The active CBD available in the flower can be purified and concentrated using precise production techniques. When oil of high potency and concentration is derived from the glands then it can be used in lesser dosage. This lesser dosage saves money as CBD oil is an expensive product but produces the desired effect.
“There’s no oversight,” says Marcel Bonn-Miller, PhD, adjunct assistant professor of Psychology in Psychiatry at the University of Pennsylvania and author of the JAMA article. Beyond the label, he adds, “There’s no consistency. You know that every Hershey’s bar you buy and every Coke you buy will be exactly the same. But that’s not the case with the majority of CBD products. It’s not unexpected to see variability within a given brand.” This means that you may notice improvements the first time you buy and try a particular product, but none the next.
Whole plant CBD oils can be made in a variety of ways. The “original” CBD oil was created by Rick Simpson. This method requires you to soak the plant material in a solvent, such as grain alcohol. Once the material soaks, the remaining liquid is full of CBD (and other cannabinoids), you evaporate the solvent and the remaining oil is ready for consumption.
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.
Given CBD’s reputation as a popular, artisanal remedy, one would think that Epidiolex would command a lot of “off label” attention. After all, physicians often prescribe pharmaceuticals off label to treat conditions that were not the actual focus of clinical trials. But the costly price tag for Epidiolex (more than $30,000 annually) precludes off label prescribing as well as affordable access for tens of millions of Americans without health insurance.
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.
Supercritical CO2 extraction is also the key to understanding more cannabinoids in cannabis like Cannabichromene (CBC) and cannabicitran (CBT) and how they interact with each other (called the Entourage effect). This can lead to increased understanding of marijuana in the medical field, and will also allow growers to come up with more effective, new and exciting strains.
And without high-quality trials, experts don’t know how much is best for a given purpose. The staff at Roth’s dispensary told her, “Try some once or twice a day and see what happens.” (Half a dropper’s worth was a good amount for her.) One thing scientists feel confident about is that CBD is not dangerous. It won’t damage vital organs even at doses as high as 5,000 mg a day, Marcu says, and nobody has died from simply overdosing on a cannabis product.

Your statement about cannabis being illegal is misleading. Cannabis is the plant/herb itself. The difference in what is legal vs illegal to all states is the flower of the herb containing THC. Anything < 0.3% is regarded as HEMP as the constituents lack enough of the THC compound to create the psychoactive effect. MARIJUANA is known for the psychoactive effects. They are both forms of CANNABIS.
For example, it eases pain and inflammation. It can also help treat anxiety, epilepsy, and some types of cancer. These are just a few of its many benefits. CBD oil provides relief without the psychoactive effects created by THC. Without the buzz, there are more medical uses for the drug. In order to separate CBD from the THC and other parts of the plant, you have to extract it. The end product is CBD hemp oil.
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.

CBD hemp oil is the product derived from the hemp plant, which is high in CBD (cannabidiol) and low in THC (tetrahydrocannabinol). This oil has received a large amount of attention in recent years, due to the growing wave of marijuana legislation and debate in many countries, including the United States. While cannabis and smoking marijuana (which often has a high level of the psychotropic compound THC) is still illegal in many places, as more is being learned about CBD, and its potential effects on health, it is becoming more and more accepted as a legal and safe remedy for a wide variety of health conditions. Since it has a minimal amount of the psychotropic compound THC, use of this oil does not result in a traditional “high”, so its effects are generally considered therapeutic, not mind-altering.
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.
Scott Shannon, M.D., assistant clinical professor at the University of Colorado, recently sifted through patient charts from his four-doctor practice to document CBD’s effects on anxiety. His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says. But he says he can’t discount a placebo effect, especially since “there’s a lot of hype right now.”
The benefits of cannabidiol are being studied thoroughly. As of now, we know that CBD works positively with our endocannabinoid system, which is responsible for keeping our body in homeostasis (balance). Cannabidiol reacts with the cannabinoid receptors to maintain that balance. CBD oil products are used for their effects ranging from soothing sore muscles and joints, inflammation, calming, promoting more restful sleep and more.
Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.
THC-dominant edibles (like chocolates) can carry an even higher risk. “It can take one or two hours to feel an effect from ingestion as opposed to a few seconds from inhalation,” says Dr. Bonn-Miller. “This makes titration very difficult.” Add to that, an edible is made to taste good. So you can easily eat more than you should in the course of a few minutes—and end up feeling negative effects hours later.
Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.
CBD—or cannabidiol—is a type of cannabinoid, a family of molecules typically associated with marijuana, but in fact, also found in other plants and even humans (in us, they’re called endocannabinoids). There are hundreds of different cannabinoids in marijuana. The best known is tetrahydrocannabinol, or THC, a chemical in marijuana that targets and binds to certain receptors in the brain to give you a high. CBD is non-psychoactive and non-addictive, and it seems to bind to multiple target sites, thereby affecting a range of systems throughout the body.
