Considered the most scientific method this is also among the cleanest techniques of extraction. Referred to as sub-critical or super critical CO² method, it uses carbon dioxide under different pressures to extract the medicinal oil. This is among the most expensive techniques of extraction due to use of hi-tech equipment that can be operated by trained personnel only. The advantage of this technique is that the end product is the purest form of CBD oil which is highly potent and free of chlorophyll. However if the heat used during extraction is too high it can damage terpenes in the oil that have therapeutic benefits and provide flavor and essence to the oil strain.
With the variety of CBD concentrations and other compounds that hemp offers, full spectrum CBD products can cover all ground. If we were to directly compare the two, scientists point out that full spectrum CBD works with the endocannabinoid system entirely. Isolate products, such as crystal, the highest quality cannabidiol and natural ingredients, and will deliver the most amount of CBD to your system at once. Ultimately, preference is subjective to the user’s condition and system.
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.
Because the FDA considers CO2 extraction to be GRAS or “generally regarded as safe” for commercial extraction, this method is popular in the food industry. The stability of supercritical CO2 also allows most compounds to be extracted with little damage. In the coffee industry, supercritical CO2 is already widely accepted as safer than traditional solvents to extract the caffeine from decaffeinated coffee beans.
Keep in mind, too, that CBD product companies use different CBD sources, extraction methods and production techniques – and not all resulting products are created equal. You'll have to do your own research to determine which companies you're willing to trust, Asquith says. Plus, how the products are packaged and consumed – be they in oils, creams or capsules – affect how they're absorbed in the body. Edibles, for example, are well-absorbed, while oils taken under the tongue are "baloney," Tishler says. And of course, salespeople at herb shops don't have the same mission, knowledge, training or oversight as physicians and pharmacists. "We have spent the last 100 years or so developing the pharmaceutical system because it works," Tishler says.
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.
When looking at isolate, it is important to verify the purity. While many are in the 99.9+% range with no identifiable amounts of THC, there are lower purity ones (such as 99.5% or lower) that may still have trace amounts that show up on the labs. This small amount is typically negligible, and is nowhere near the amount usually found in full spectrum products. But it’s still something to be aware of for those seeking the purest they can find.
While cannabidiol (CBD) is all the rage at present, it is often hard to understand what you are getting. Furthermore, with so many different CBD products on the market, it’s hard to tell which are full spectrum, which are not and which products are made from CBD cannabis or CBD hemp.  In this article we will try to clear up any confusion, focusing the major part of the post around Full Spectrum CBD oil.
'If the Patient Information Leaflet that comes with your medication says to avoid grapefruit juice, for instance, then do not take CBD, as the same type of interaction can affect circulating blood levels of your medicine. Even if the leaflet does not mention grapefruit juice, you should still check with your doctor before taking CBD. You should also not take CBD if you are pregnant or breastfeeding.’
Blood pressure. Scientists say that CBD can also aid the lowering of blood pressure in humans, mainly by reducing the body's systolic pressure in the arteries as the human heart pumps blood. By taking a moderate dosage of CBD oil, some health experts say, an individual can improve blood flow, lower the heart rate and reduce the anxiety the stress often found in patients with high blood pressure.
The plants are cultivated and then sent for extraction. Some CBD oil-based products come from whole plant extracts. Others are derived from isolates. Whole plant extraction is self-explanatory. The entire plant is part of the process. Those in the medical communities prefer this method. They believe that a broader spectrum of cannabinoids yields during whole plant extraction. According to medical specialists, capturing the entire cannabinoid spectrum stimulates the endocannabinoid system. They call this the “entourage effect.”
CBD hemp oil has a huge range of potential health benefits and uses, including reducing pain, soothing anxiety, fighting chronic diseases, improving mood, eliminating depression, preventing inflammatory arthritis, protecting the immune system, balancing the metabolism, aiding sleep disorders, and healing the skin, among others. CBD oil can also be used in many different ways and has a variety of applications for natural health.
So, many of CBD's popularized benefits aren't well-proven. But are there any harms in trying CBD-containing products? In a word, yes. While any reported side effects from CBD alone are minor (think dry mouth and dizziness), they can be serious if the CBD products interact with other medications, experts say. Since CBD is metabolized by the same enzyme in the liver that metabolizes many conventional medicines and supplements, the chemical can cause the levels of other drugs in the system to rise; in some cases – like for those taking a drug to prevent their bodies from rejecting a donor organ – to a deadly level, Tishler says.
Cannabigerol is known as the stem cell cannabinoid for its role as a precursor to other cannabinoids found in hemp and marijuana. Previously overlooked as a significant cannabinoid, the role of CBG is becoming better understood, and companies like Medical Marijuana, Inc.’s AXIM® Biotechnologies are starting to research its potential. Because most CBG is transformed into other cannabinoids like CBD or THC by the cannabis plant, natural CBG levels are low in most processed cannabis plants.

At this point in time we have multiple states selling medical marijuana and other states looking to jump on board where there are other states that seemingly will never be open to the idea of legal cannabis. The decision on cannabidiol isn’t getting any easier, and company propaganda isn’t helping any. I think it’s obvious after talking to people from both sides of the spectrum that this choice is not cut and dry, and instead is something that you, the cannabidiol buyer, has to educate yourself on so you can make a fully informed decision.  While there are still choices for you to make, I now hope you have the information and facts to make an educated choice.
And, if you do luck out and get a tincture truly containing CBD, you'll likely dish out $200 or so to take 10 to 40 milligrams daily. Since research participants take closer to 1,000 milligrams a day, it's hard to imagine a benefit without drinking the whole (expensive, calorie-dense) bottle, Tishler says. "Most people will adjust their doses based on what they're comfortable spending," Asquith says.
So which is better? Hemp derived CBD or Medical marijuana derived CBD?  I believe, given the information I have found, that the reasonable and definitive question we should ask is: What are the pros and cons of both options and, most of all, what will be best for me and fit my lifestyle. In addition, legality within the state and country you live must be taken into consideration.

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.
Full spectrum (or “whole plant”) products contain CBD as well as terpenes and other cannabinoids such as CBG, CBN and trace amounts of THC. Usually these will be in ratios that were naturally-occurring and extracted from the plant and specific strain. Terpenes and cannabinoids are occasionally added back into products as an isolated form to raise the potency of the product.
Extracts of CBD—either from marijuana or hemp (a cannabis variant that is essentially free of THC)—are sold as an oil or in tinctures. You can also get CBD via a transdermal patch, capsule, sublingual spray, gel, cream, or vapor. Some contain pure CBD extract (or so they say); others—particularly if you’re in a state where recreational marijuana is not legal—will contain hemp extract, which includes CBD as part of its makeup. As of this reporting, recreational marijuana is legal in nine U.S. states and medical marijuana in 29. Don’t miss these 50 weird things that are banned in the United States.
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.
