You need a series of chambers for CO2 extraction. Their role is to control pressure and temperature. The pressure and temperature in the chambers force the CO2 cannabinoid solution to react with one another and then separate. As the cannabinoids separate, the chambers collect them separately. The extractor can then choose which cannabinoids to put into their product or products.

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 His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says.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.”
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.

That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.

By formulating our products with pure, full-spectrum hemp oil, we ensure that all the cannabinoids naturally found in the plant are in the hemp oil you buy from us. This also allows the cannabinoids to interact with the endocannabinoid system in what has become known as the entourage effect: when all the ingredients in hemp oil, including the terpenes, vitamins, and range of cannabinoids are allowed to work with the body naturally, as they would in the natural plant.


Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
Cutting-edge science has shown that the endocannabinoid system is dysregulated in nearly all pathological conditions. Thus, it stands to reason that “modulating endocannabinoid system activity may have therapeutic potential in almost all diseases affecting humans,” as Pal Pacher and George Kunos, scientists with the U.S. National Institutes of Health (NIH), suggested in a 2014 publication.
If this is not sufficient for calming your symptoms, a gradual increase of another 25 mg per day, over the course of 3-4 weeks, is recommended. While there have been no reports of more serious side effects when this oil is taken in larger concentrations, it is best to slowly increase your dose to find a comfortable and effective level, given your individual characteristics and needs.
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.
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!

In another, a specific combination of CBD and other secondary cannabinoids were found to work together to slow tumor grown in cases of colon cancer. These sorts of synergistic effects are fairly common in whole plant extracts, and aren’t unique to cannabis. However, the sheer volume of active compounds in cannabis extracts, and their wide-ranging effects certainly distinguish them from other plants.
Each bottle of Bluebird Botanicals CBD oil comes with a precise dropper, making it easy to measure your exact serving size and adjust it according to your body’s needs. This also allows you to easily combine the CBD oil with any other CBD product to introduce more variety and enrich your daily CBD experience. You can try the Classic Hemp oil alongside any CBD edible or right before your CBD vape for a synergistic effect.

At least one benefit of CBD is well-supported by science: It can be effective in treating children with rare, genetic seizure disorders. Adults, children and even animals with epilepsy have been shown to benefit from the chemical too, the World Health Organization reports. There's also some evidence that CBD can help with anxiety, says Dr. Robert Carson, an assistant professor of neurology and pediatrics at Vanderbilt University who focuses on children with epilepsy. "In children, especially those with autism spectrum disorders, this may manifest as improved interactions with others," he says. Other preliminary research shows CBD holds promise for conditions including Alzheimer's disease, cancer, psychosis and Parkinson's disease – and is pretty much impossible to abuse or become addicted to, WHO says.
