Not much, as far as humans are concerned—at least not yet. The vast majority of studies have been on animals, as of yet, and there are few high-quality studies on humans. Even the oil’s effect on pain—something that CBD oil is popularly used for—isn’t proven. “The studies available are small or not well designed,” says Dr. Devinsky. “There’s a lot of religion out there, but not a lot of data.”
Now that cultivation of hemp has become legal in some parts of the world there are widespread discussions about how the medicinal properties of CBD oil is curing people of varied illnesses. Since it is derived from hemp which is a strain of cannabis, people had apprehensions about this product but now with widespread media coverage usage has become common in therapy clinics. CBD is one of the many cannabidiols that exist naturally in the Cannabis plant along with THC.There is difference between plants rich in CBD and those rich in THC as the former is called indica-dominant plants while latter is sativas rich plant. While sativas rich plants give an uplifting feeling, the indica rich plants give the body a relaxed feeling that is ideal for people in acute pain.
Being a relatively inexpensive method it is preferred by small scale producers of CBD and THC oils. During extraction this method uses solvents like butane, ethanol and alcohol derived from grains. This method has several disadvantages the worst of which is potential of explosion while the second is leftover residue of these solvents. Scientists and doctors advice against the use of this method as it can make the end product unsafe for medical use and also can make existing medical condition much worse. When there are unsafe residues in CBD oil it reduces healing powers and can even compromise health of patients.
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.
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.
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.
To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases. But because all these products are illegal according to the federal government, cannabis advocates are cautious. “By and large, the federal government is looking the other way,” says Paul Armentano, deputy director of the Washington, DC–based National Organization for the Reform of Marijuana Laws (NORML), but until federal laws are changed, “this administration or a future one could crack down on people who produce, manufacture, or use CBD, and the law would be on its side.”
Lab techs use state of the art equipment to create phase changes in carbon dioxide by utilizing temperature and pressure. The carbon dioxide is cooled and compressed to upwards of 10,000 psi – by comparison your car tire is pressurized to about 300 psi. When compressed to these extremes, CO2 becomes ‘supercritical’, which simply means that it converts to liquid when placed under extreme pressure.

There are more than 80 cannabinoids found in cannabis plants, with THC being the primary one, followed by CBD. However, in the hemp plant, which is a different strain of the species Cannabis sativa, CBD is the main active ingredient, and THC is barely present, making its use and legality more widespread. The reason that CBD is such an effective form of support for human health is due to the body’s endogenous cannabinoid system. This regulatory structure of the body has millions of cannabinoid receptors in the brain and nervous system, which react not only to plant-derived cannabinoids (such as hemp and marijuana) but also to natural cannabinoids produced within our body. When hemp oil is used and processed by the body, it is effectively boosting the function of the endocannabinoid system, helping our body regulate itself in many different ways.
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.”
First, ethanol is a polar solvent. This means that it will readily mix with water and dissolve water-soluble molecules. This creates a great challenge for companies using the ethanol extraction method because chlorophyll is one of the compounds that will easily co-extract. Chlorophyll in the concentrate will result in a dark green coloring and an unpleasant bitter, grassy flavor.
CBD isolate is pure CBD, extracted and purified until none of the plant’s other constituent compounds remain. It has been isolated down to just the CBD molecule. This purity and potency is why it’s the preferred treatment for patients needing unadulterated doses of CBD and nothing else. It has no other active ingredients and its purpose is simply to deliver therapeutic doses of CBD. CBD isolate products often come as a white powder or a mix with a oil.
For the large majority of average users though, a high-quality full-spectrum CBD oil will be the better, more efficient option. These concentrated oils have delivered incredible results so far, and have been observed to effectively treat everything from anxiety, to diabetes, to severe chronic pain. And with the inevitable continued research that’s to come, it’s expected that the quality of full-spectrum products will only continue to get better and better. (And of course, given that hemp products are legal in all 50 states, you don’t even need a medical marijuana card to purchase it).
The same terms could be applied to what's actually in CBD products. While some do contain CBD, others (often marketed as "CBD-rich hemp oil") may have barely any, Asquith says. And depending on state laws, they can include varying levels of THC too – a combination shown to have some benefits, but also drawbacks, of course, if you're not looking for a high. "People will play all these games with the numbers because the consumers aren't really educated in this space yet and it's easy to get taken advantage of," he says. "It's the milligrams of the actual CBD molecule that matter."
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”
What a great article. I have learned a lot on CBD/Hemp. I personally have testimonials that prove that it works and changes lives. My father for one has anxiety and it has helped him tremendously. There are so many benefits but not enough time to mention. I do know it works but I also know not all are equal. There are 5 things you really need to look for when picking one.
Dr. Devinsky’s research, which was recently published in The New England Journal of Medicine, is beginning to provide that much-needed data in the field of epilepsy research. In a landmark multinational randomized double-blind study for a treatment-resistant form of the condition, subjects taking an oral solution of 20 mg CBD per kilogram of body weight for 14 weeks, along with standard treatment, experienced a 42 percent reduction in drop seizures (the muscles go limp). Those taking a 10 mg CBD per kilogram of body weight saw a 37 percent decrease; patients who got a placebo saw a 17.2 percent decrease. The mechanism hasn’t quite been worked out yet, Dr. Devinsky says, though there’s some evidence that a receptor known as GPR55 may be critical for the anti-seizure effect.

With that being said, let’s discuss the wonderful thing we call CBD oil. CBD, cannabidiol, is one of over 85 active cannabinoids identified in hemp and other cannabis plants. CBD oil is derived from hemp, due to its abundance naturally occurring in the plant. CBD oil is extracted using the whole plant, stalks or flowers. Since hemp contains only trace amounts of THC, CBD oil products are non-intoxicating.
Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD.
