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.
While it wasn't like I was 100% stress-free overnight, I did notice within a week or so of taking CBD oil — roughly six to eight drops under the tongue, held for 90 seconds and then swallowed, twice a day — that I felt less anxious and tense. Things that usually bothered me, like unanswered emails or things going wrong with work, were easier to take in stride.
We have 20 lb dog that is an idopathic epileptic. He is currently on Keppra (375 mg three times daily) and phenobarbital (32.4 mg two times daily). We have CBD oil and want to use it. We have seen many documentaries and articles of it’s positive effects on epilepsy. One thing always seems to be missing is the dosage level. What dosage level should be used for a 20 lb dog and how often? We believe in this, but don’t know how to administer it correctly.
Bacon had said that I might need to try two full droppers worth of the oil to really feel its benefits. I knew that I had an incredibly busy and stressful day ahead of me—I needed to fit in a five mile run before work, had lots to do at the office, was scheduled for a busy event in the middle of the day, and had a 2-hour meditation class later that night which would require a lot of mental clarity. Tentatively, I squirted two droppers of CBD oil into my bulletproof coffee and sipped away.
So to gain a higher production of THC in a field of cannabis plants, you simply take away the male plants so the females can’t be pollinated, and to lower THC production, you keep the male and female plants together. Plants used for CBD oil or CBD capsules or hemp oil or hemp protein or your hippie neighbor’s tie-dyed hemp headwear meet the international standards of less than 1% THC.
At first, some people who deal with anxiety are apprehensive about CBD oil because it comes from essentially the same plant as marijuana. Marijuana contains THC, which is the psychoactive compound that causes you to get ‘high’ during use, and can lead to increased anxiety or paranoia. CBD oil is nothing like marijuana, and it does not contain THC at all. CBD oil can actually treat some of the adverse effects of THC.

Cannabidiol did not reduce responses to negative emotional stimuli or reduce anxiety in healthy participants, according to a study published in Cannabis and Cannabinoid Research in 2017. Researchers tested participants' responses to negative images or words and threatening emotional faces and sensitivity to social rejection after taking oral cannabidiol.


Currently available pharmacological treatments include serotonin reuptake inhibitors, serotonin–norepinephrine reuptake inhibitors, benzodiazepines, monoamine oxidase inhibitors, tricyclic antidepressant drugs, and partial 5-hydroxytryptamine (5-HT)1A receptor agonists. Anticonvulsants and atypical antipsychotics are also used to treat PTSD. These medications are associated with limited response rates and residual symptoms, particularly in PTSD, and adverse effects may also limit tolerability and adherence [7–10]. The substantial burden of anxiety-related disorders and the limitations of current treatments place a high priority on developing novel pharmaceutical treatments.
“Pre-clinical evidence largely shows that CBD can produce beneficial effects in AD, PD and MS patients, but its employment for these disorders needs further confirmation from well-designed clinical studies. CBD pre-clinical demonstration of antiepileptic activity is supported by recent clinical studies in human epileptic subjects resistant to standard antiepileptic drugs showing its potential use in children and young adults affected by refractory epilepsy.” View Source
Those warning letters aside, there’s not a lot of federal oversight right now over the claims being made or the products that are being sold. Cohen warned against buying CBD products online, because “there’s a lot of scams out there.” Yet his clinic sells CBD, and he admits, “I say ‘Don’t buy online,’ but ours is worth doing, because we know what we’re doing. We ship all over.”
CBD also appears to counteract the sleep-inducing effects of THC. This is what makes CBD so appealing to the medical community, as the cause of psychoactive side effects has been a major barrier in the acceptance of medical marijuana. (20) While THC is known to cause anxiety and paranoia in some people, CBD works to counteract those side effects. For this reason, CBD benefits extend to being used in clinical trials on young children with epilepsy.
With people across the globe mobilizing, putting their bodies on the line, and getting arrested en masse as part of a broad effort to force the political establishment to immediately pursue ambitious solutions to the climate crisis, new research published on Monday provided a grim look at what the future will bring if transformative change is not achieved: colossal flooding, bigger fires, stronger hurricanes and much more.
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.
Chronic pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
As one might expect from the information presented in the previous sections of this article, the position of cannabidiol (both from a medical and from an institutional point of view) is one of uncertainty. To add insult to injury, private companies (especially those targeting immediate profit with a minimum of investment) take advantage of the loopholes in legislation to gain from the media exposure that CBD has had in the past few years.

Hi Lauren I've just started today with 250mg cbd oil. I'm starting low to see what happens. I've nerve damage across buttocks from a laminectomy. I've not been able to sit for 5 years. I've recently started with a muscle spasm in my left buttock and the muscle above is painful. It is only the first day, also tried a cbd night time tea as well. Do change in muscle pain so tight on my left hand side. How long before felt it starting to work please. I'm trying not to expect changes straightaway. I also take 1100mg gabapentin and 30mg amitriptyline and I hate both of them - they both can cause muscle tightness affecting the nerve. Thank you Lyn

Here is a statement from one of the studies concerning CBD and glaucoma and was presented as an opening statement in the Future Direction section of the study.  It states, “Cannabinoids have the potential of becoming a useful potentially relievement for glaucoma, as they seem to have neuroprotective properties and effectively reduce intraocular pressure.”
Now don’t get me wrong – some will indeed claim that cannabis is addictive. For example, the Boggs Act of 1951 established mandatory sentences for drug users and also claimed that cannabis was addictive. But since then, testimony given by Dr. Harris Isbell, Director of Research at the Public Health Service hospital in Lexington, Kentucky exposed this as false, explaining how cannabidiols from marijuana are not physically addictive.
Cannabis has always been a popular form of treatment for a variety of medical conditions, but in the 1930’s growing concerns about the dangers of marijuana abuse led to cannabinoids being banned. A century has past and despite all efforts from cannabis enthusiasts through social media channels and online media, cannabis is still classed as a schedule 1 drug.

Hi, In your wonderful CBD overview above you state that the reason you started using CBD oil in the first place was to lower your cortisol levels. Did you succeed? If you are comfortable with doing so can you share the ‘before’ levels and the ‘after’ levels? Or maybe just the amount of the drop (average)..?? And, was this CBD product you now sell the one that you were using then?


"The data supporting efficacy and dosing are specific to one product: Epidiolex," Bonn-Miller says. "That's not necessarily translatable to 'Joe Bob's CBD Blend.'" A CBD extract you buy online or in a dispensary will almost certainly have less CBD in it, he explains, and will contain other cannabinoids—meaning that it will work differently and will need to be dosed differently. "This is not to say that 'Joe Bob's CBD Blend' definitely isn't going to be effective for pediatric epilepsy, but it means that we need to study it before we know."
An actual long term study, Ganja in Jamaica: A Medical Anthropological Study of Chronic Marijuana Use, which was published in the Journal of the American Medical Association in 1975, showed zero concerns with addiction, even after patients who had used cannabis for decades had stopped. The 1980 study Cannabis in Costa Rica: A Study in Chronic Marijuana Use backed this up. Most interestingly, studies like this are not finding any addictive potential with CBD even in the presence of THC!
My mother was thinking about trying CBD because she heard it would help with her diabetes and I was wondering how good is CBD at controlling sugar levels as my mother has tried multiple insulin drugs and they might work for a while but then stop working from what I understand. She got her diabetes from the Growth Hormone Drug back in 2009 and she also got some type of rare mouth Tumor which the doctor did the surgery to remove it wrong and caused it to spread. Will this work at controlling her sugar levels as she gets both high and lows, for example, she once had her sugar levels so high that it was unreadable and the doctors were amazed that she was still alive plus she also gets lows sometimes. Also, because of diabetes, she has neuropathy where she is losing feeling in her toes and does not feel the heat from hot products when she picks them up, will this product also help with the neuropathy and any remaining tumor?
The following medications and other supplements may interact with CBD. Effects may include increasing or decreasing sleepiness and drowsiness, interfering with the effectiveness of the medications or supplements, and interfering with the condition that is being treated by the medication or supplement. These are lists of commonly used medications and supplements that have scientifically identified interactions with CBD. People who take these or any other medications and supplements should consult with a physician before beginning to use CBD.

If no effects are noticeable initially, increase your dosage every few days. It takes time for the compound to build up and affect the body. Other cannabinoids, such as tetrahydrocannabinol (THC), trigger almost immediate results (the previously mentioned “high”), but CBD’s effect is milder. Changes can take a few days to become apparent. Therefore, it's important that you stick with the same dosage for a few days before deciding to increase it.

CBD has been in the news before, as a possible treatment for epilepsy. Research is still in its early days. Researchers are testing how much CBD is able to reduce the number of seizures in people with epilepsy, as well as how safe it is. The American Epilepsy Society states that cannabidiol research offers hope for seizure disorders, and that research is currently being conducted to better understand safe use.
It's the Wild West out there. Without any federal regulatory body checking labels, consumers have very little way of knowing what they're buying when they purchase CBD oil. Bonn-Miller co-authored a study that found that 26 percent of CBD products on the market contained less CBD than their label claimed. So the amount you need for an effective dose could vary drastically, not just from product to product, but from bottle to bottle of the same product.
So am I to assume, due to no response/deleted comment that my simple question was too difficult to answer? With all the technical & correct information you have on you GREAT website, can someone (?) not simply correct or acknowledge the FACT the your NOT using nano-particle size product? I am truly interesting (for my wife) in CBD, have done my research, and I love working with numbers which is why if found this discrepancy. Comments welcome, but avoidance is disturbing.
