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.”
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.

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.
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.
We have all seen the recent news articles showcasing CBD oil and many of us would like to get involved... but where do you start?  In the event you didn’t already know, there are two sources for CBD oil and other CBD/Cannabidiol products: 1.)  Hemp CBD products made from industrial hemp and 2.) Medical marijuana CBD products derived from medical marijuana.  One is available widely online from sites like DiscoverCBD.com and the other is available at medical marijuana dispensaries across the US in states where medical marijuana is legal.

'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.’
Isolates are typically the CBD oil product of choice for those who get drug tested or are sensitive to other cannabinoids such as THC. Products labeled as isolates will generally be highlighted as being 99+% “pure CBD.” Usually, these products will have nothing but CBD in them because the CBD has literally been isolated from everything else. You can find pre-made isolate oils that typically consist of a carrier oil, such as MCT oil, infused with the crystalline isolate powder. You can also find the “raw” CBD crystalline powder or slabs (a form of concentrate) on its own.

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.
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."
A study published by David Cheng, Postdoctoral Scientist, Neuroscience Research, University of New South Wales, NSW, Australia, says that CBD has a potential as a preventive measure against symptoms of Alzheimer’s. This presents yet another exciting development for medical researchers, given the persistent challenges to finding effective solutions for this condition.
Quality is a particular concern, because cannabis plants easily soak up heavy metals from pesticides and other contaminants, Marcu says. If you are buying online, look for a company that documents how it tests its products. (If the website doesn’t indicate this, call and ask.) “Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
That being said, though, it’s still important to do plenty of research and find a reliable CBD manufacturer, before you go throwing money at any old product. Since the market is still unregulated by the FDA, there are loads of phony companies out there that are selling completely bogus products. We recommend only using oils from reliable companies with a proven track record.
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.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
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.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43% had more CBD than indicated, while 26% had less, and some had unexpected THC. “There’s a 75% chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.

CBD oil is not legal everywhere. It is banned/restricted by countries such as UAE, Dubai, and Saudi Arabia. Although CBD oil is illegal in many of the US states too, some have legalized its use for medicinal purposes. While the number would be ever-changing, as of 2016 there are 17 states in the US which have legalized the use of low THC, high CBD products for medical reasons in limited situations. These states include Alabama, Georgia, Iowa, Kentucky, Florida, Mississippi, Louisiana, Missouri, North Carolina, Oklahoma, South Carolina, Wisconsin, Wyoming, Tennessee, Texas, Utah, and Virginia. It is advisable to consult your local health specialist before use.

Miller, whose clients include patients referred by physicians, uses CBD in a variety of delivery modalities that she has found effective. “Patches can be worn for pain or anxiety management. Capsules or concentrated drops can be taken orally for pain, inflammation, sleep, and anxiety. Balms and creams can be used on the hands and feet to manage arthritic pain. Vaping is another delivery method,” she says.
Sarah Jorczyk is an advocate for CBD products and one of the Administrators of the CBD Oil Users Group on Facebook. She strives to educate the public, and promotes the use of safe products while helping others throughout their CBD journey. You can also find a variety of her content, including reviews and educational videos, on the group's youtube page.
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. 
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.
