Supercritical CO2 extraction. Subcritical/Supercritical CO2 oil extraction has several advantages over other extraction mediums, such as alcohol and hydrocarbons: CO2 is nontoxic and is Generally Regarded As Safe (GRAS) by the FDA for use in food products. Our bodies produce it when we breathe, and it is commonly used in carbonated beverages. With CO2 as a solvent for oil extraction, no toxins, heavy metals or hydrocarbon materials come in contact with the extracted oils. CO2 is “solvent free”. Other extraction solvents, such as hydrocarbon based propellants like propane and butane, hexane and pentane, or ethanol/alcohol mixtures require additional distillation or purging beyond the extraction process to separate the solvent from the extracted oil. CO2 has a very low boiling temperature and wants to be a gas a room temperature, thus it naturally separates from the extracted oil the same way a soda goes “flat”. The spent plant material is also free of residual solvents so it can be re-used as well. CO2 is non-flammable. Flammable solvents must be processed in a NEMA Class 1, Division 1, 2 or 3 (explosion proof) environment. CO2 is not flammable and does not require costly explosion proof facilities. CO2 is “cold” – Botanical oil extractions can be done at temperatures that are native to the botanical material, minimizing thermal degradation of the plant material and the extracted oil. CO2 is “tunable” – the solvency power of CO2 can be adjusted simply by increasing or decreasing pressures and/or temperatures. The ability of the CO2 to selectively extract affords the ability to create unique extractions that have varying levels of desirable oils and waxes (see below). Less desirable plant constituents, like chlorophyl, can also be “de-selected”. CO2 is inexpensive. CO2 is readily available and widely used throughout several industries. In addition, Apeks’ production CO2 oil extraction systems recirculate and subsequently recover 95% of the CO2 used in each extraction. CO2 is environmentally friendly. Industrial CO2 for extractions comes from byproducts – primarily hydrogen and ammonia manufacturing and fermentation for ethanol. CO2 used for extractions does not contribute to the overall atmospheric CO2 levels.
CBD shows promise in the treatment of anxiety disorders, according to a report published in the journal Neurotherapeutics in 2015. Looking at results from experimental research, clinical trials, and epidemiological studies, the report’s authors found evidence that CBD may help treat generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder. However, the authors caution that human-based research on CBD and anxiety is fairly limited at this point.
CBD oil may be of some benefit to those with addiction, suggests a review published in the journal Substance Abuse in 2015. In their analysis of 14 previously published studies, scientists determined that CBD may have therapeutic effects in people with opioid, cocaine, and/or psychostimulant addiction. They also found that CBD may be beneficial in the treatment of cannabis and tobacco addiction. There is some evidence that CBD may block or reduce the effects of THC on the mind.
While there are more unknowns than knowns at this point, Grant says he doesn’t discount all the anecdotal CBD reports. “You hear somebody say, ‘Hey, I gave this to myself and my kid and we feel a lot better,’ and we should never dismiss that kind of information,” he says. He points out that many modern medicines were discovered when researchers followed up on exactly this sort of human trial-and-error evidence. “But we still need to do the studies that confirm whether all the good things are true, and how much to give, and how to give it,” he says. “These are all questions that need to be answered.”
I wanted to know something about your part in the absorption of CBD. You talked about how CBD is non water-soluble and the best way to get the full effect is to either take a large amount OR vaporize it which you considered to be annoying or unnecessary. I on the other hand have no quarrels with doing this as I am an occasional smoker. Since you didn’t elaborate much on vaporizing, does this imply that it is still an adequate route to getting a better effect of CBD?
Good morning! Reading through your article, I'm completely impressed and thinking of the various clinical applications (that depressed patient, that anxious one, my arthritic knees!) for the CBD's. THEN you talk about your product, the combination of co-factors sounding really great, but the nano-particles alarm me. There is a fair amount of research about the hazards of nano-particles in cleaning and cosmetic products, I'm wary of ingesting them for fear of nano-sized items going afield of where I'm intending them to go.
Hi Ben. What are your thoughts on the differences, if any, between CBD extracted from hemp (legal to buy for anyone in the US) and CBD extracted from medical cannabis? My instinct is that once extracted, they should be identical because we’re talking about a specific molecule (similar to how ascorbic acid extracted from an orange or bell pepper or made in a lab are identical). However, I had some CBD oil from a major retail website that did not do much for my insomnia, even at high doses. Then I tried some CBD oil from my medical marijuana doc that he claimed was pure CBD (meaning no THC, but I am not sure if there are other terpenes) and of higher quality because it was extracted from medical grade cannabis. I was totally skeptical, but ending up feeling it big time – very calming, almost like being high, but without the random racing thoughts that THC gives me. I am wondering if it’s worth it to shell out for my doc’s product (it is super expensive), or if I should just try another version of hemp-based CBD, such as the one you recommend.

I assume this is also a side effect of the eased anxiety, but I seem to fall asleep within the 20- to 30-minute range rather than my normal 45 minutes to one hour (or longer). Not only do I seem to be skipping (or at least shortening) the whole tossing-and-turning phase of my sleep cycle, but I'm able to snap out of the overthinking mindset that often keeps me up at night. Of course, there's no telling whether a big life event would kindly disrupt this newfound bliss, but I'd like to think it's helped on day-to-day basis.
As the brain ages, the creation of new neurons slows down significantly. In order to maintain brain health and prevent degenerative diseases, new cells need to be continuously created. A 2008 study showed that low doses of CBD- and THC-like cannabinoids encouraged the creation of new nerve cells in animal models, even in aging brains.[192] CBD also benefits the brain by helping to prevent other nerve-related diseases like neuropathy and Alzheimer’s disease.

I wanted to tell people here that CBD has been very effective for my anxiety, and helps with insomnia. For me, it was a cumulative effect, after a week of one dropper of oil, I can sleep very well at night. I feel like I am not polluting my body with commercial pharmaceuticals. I wish everyone here the best, and hope it works for you as well as it has for me.


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.
On the other hand, a 2017 comprehensive review of CBD studies in psychiatric disorders found inconclusive results. According to the authors, there isn’t enough evidence to claim CBD as a treatment for depression. However, the authors do note positive results for anxiety disorders. Based on their review, more human tests are needed to better understand how it works, what ideal dosages should be, and if there are potential side effects or hazards.

CBD oils are used for a wide range of ailments whether its joint and muscle pain to stress reduction or improving overall mood. There are a lot of CBD oils currently on the market making it difficult to decide which product is the right fit for you, in this article we are going to have an in-depth discussion about some of the best CBD oils, so that the next time you are in the market you’ll know exactly what to look for.


Because it does not produce psychoactive effects and hemp is not a controlled substance, hemp-based products are legal to sell, buy, and possess in all 50 states. However, the law is a bit more complex when discussing CBD oils and other hemp byproducts. According to the 2014 Farm Bill, hemp should only be grown and cultivated for academic research purposes. This means that, technically, any hemp-derived oil that is not grown for these purposes would be illegal — though this law is rarely enforced. To make matters more complex, the laws are somewhat unclear in certain states. Sen. Mitch McConnell of Kentucky recently introduced legislation that would legalize all hemp products at the federal level, but this decision is still pending.
CBD oil is a relatively new product to the high street health market, meaning the burning questions are coming in thick and fast. And what better way to find out all the answers than to take a trip to Celtic Wind Crops' cannabis farm in County Louth, Ireland, where they grow hemp and manufacture the 5% strength CBD oil (and powder, and capsules) that has become the first CBD product to be sold in a UK Pharmacy (LloydsPharmacy). Here's everything I learned:

Stage III Vulvar Cancer is visiting my body. I am taking CBD oil from the dispensary in Massachusetts. I put a rice grain size rubbed inside my mouth under my tongue. It is so terrible tasting, especially now with Chemo and Radiation, my stomach is ok, but I am getting almost nausea when putting the CBD Oil on my gums. Can I take it rectally or vaginally? Have you ever heard of this? Is it still just as effective as taken orally. I am only doing this because of my condition. It does help me sleep and I am more relaxed. I just wish I did not have to taste or smell it.
Grown and extracted from the USA, our quality CBD is fully compliant under the Kentucky Department of Agricultural Industrial Hemp Pilot Program. Our CBD products are legal and shipped to all 50 states and internationally. All of our CBD products contain 0% THC, guaranteed. We utilize a whole plant CO2 extraction that allows us to draw the CBD from the plant material and filter out unnatural substances, maximizing pure CBD concentration. Each and every product that leaves the facility is third-party tested to ensure consistency and quality.

If you’re anything like me and often have trouble falling asleep at night, you will definitely like CBD products. Being a CBD user for long time I have been taking CBD oil for Insomnia a long time I’ll say it has helped my sleep better. From what I know Cannabidiol a.k.a CBD is great relaxant that have helped many people, including me, sleep better. With dosage I always recommend to my friends to start with low, then see if it suits them and then work their way up.
Naturally, the testimonies of these experts were based on a comprehensive literature review, an endeavor which we have also undertaken, albeit in a less official capacity. While many new products have been hailed as a panacea in their times, and many web sources certainly allude to this status for CBD, our objective was more modest – presenting ten possible benefits of cannabidiol where sufficient evidence exists to back up the claims.

It is well known that people who consume cannabis in other forms notice increased appetite, famously called “the munchies”. However, cannabis essential oil can help regulate your appetite and induce hunger, while also stimulating your digestive system to operate at a regular level. This can help people who want to gain weight quickly, particularly after an extended illness or injury.
The findings imply that cannabidiol can also be a healthy alternative for patients who have got accustomed to powerful painkiller doses. CBD does not have any steroid properties, and it is an anti-inflammatory drug that is less powerful than analgesics based on opioids. But, CBD is much more prescribed because of its non-side-effect causing properties.

A study published in the Journal of Clinical Investigation and the National Institute of Health discovered that CBD can provide treatment for acne. Researchers used cannabis-derived Cannabidiol on the human sebaceous glands and came to the conclusion that CBD acts as a highly effective sebostatic and anti-inflammatory agent by inhibiting lipid synthesis.
Some studies show that CBD can counteract these adverse effects, but more research is needed, as most of this research is done on animals or is based on anecdotal reports. Little research has focused on the safety and side effects of CBD in humans; however, clinical trials indicate that only a few, generally mild side effects have been observed after CBD administration and tolerance for CBD does not seem to occur.

For people who suffer from insomnia, constant anxiety during the night or simply struggle to get a sound, restful night of undisturbed sleep, cannabis sativa essential oil may work like a charm. However, according to a research report published by Dr. Ethan Russo, Director of Research for the International Cannabis and Cannabinoids Institute, terpenoids produce an “entourage effect”.
