Gloss and Vickrey conducted a Cochrane systematic review of the use of CBD in the treatment of epilepsy (11). Their methodology included only those trials that were randomized and controlled and excluded case series, case reports, and expert opinion. They were able to identify only 4 randomized controlled studies reported in the literature, and they included a letter to the editor and an abstract. The total number of subjects enrolled in these studies was 48 (11–14). While only four studies and a letter to the editor were in the actual analysis, the authors included a complete reference listing of all articles reviewed for inclusion.

Cannabidiol, or CBD for short, is a phyto-cannabinoid found in cannabis plants. However, it does not cause the same psychoactive effects as other naturally occurring cannabinoids (such as tetrahydrocannabinol, or THC). CBD induces feelings of sleepiness and tranquility, making it suitable for insomnia and other sleep disorders; CBD can be used to alleviate symptoms of epilepsy, diabetes, and anxiety disorders, as well. Legality is an issue for some; all 50 states have laws governing the sale, possession, and use of CBD, and they vary significantly (see the table below for a full analysis).


Great article! Excellent point by Matt, precisely why I found this article. I would just add that the CBD percentage in the extract can be significantly lower than even the 20%, but its probably fair to use that to give a rough idea how much CBD might be in an Amazon product, so divide the claimed percentage by 5!. Claims of up to 60% on Amazon are totally ludicrous, any concentration above 20% CBD become darker very viscous and the CBD starts to crystalize in the bottle! You would need to heat the bottle (which can damage the properties of the carrier oil) to re-liquidize! Also beware of Amazon reviews which are notorious for being fake. As author suggests, contact seller for full data sheets or seek a reputable supplier elsewhere that gives full transparency of information up front.
In short, CBD oils made from hemp must contain less than 0.3% THC – this is below the legal federal limit (and is why many CBD oil companies claim to be able to ‘legally ship to all 50 U.S. states’). In contrast, cannabis CBD oils (that you’d find in places like medical marijuana dispensaries) may have a much higher THC content, given that they are made from marijuana rather than hemp.

Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Without sufficient high-quality evidence in human studies we can’t pinpoint effective doses, and because CBD is currently is mostly available as an unregulated supplement, it’s difficult to know exactly what you are getting. If you decide to try CBD, talk with your doctor — if for no other reason than to make sure it won’t affect other medications you are taking.

Amazon reviews are few, yet most consumers have stated excellent benefits in using Sana & Salu Hemp Oil for both pain and as a skincare treatment. For those that have experienced assistance with pain, reviews are even fewer. Even so, it seems many consumers of this oil use it as more of a dietary supplement rather than a means to manage symptoms. In general, all amazon reviews are positive despite some uncertainty regarding full spectrum hemp oil (containing CBD) and hemp seed oil (which contains no CBD).
CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.
Pioneers of the CBD industry, 4 Corners Cannabis helped pave the way for companies that want to provide quality products and utilize best practices. They grow their own strain of hemp and make small batches of true full-spectrum CBD products. Their prices place them lower down on our ranking, but their highly satisfied customers are more than willing to pay for the 4 Corners quality.  
I’ve been vaping ejuice for almost 3 years now. Its offered both my husband and I the ability to quit smoking cigarettes. I’m dealing with chronic back and shoulder/neck pain, some anxiety, and insomnia. I vape at a 6% nicotine level, can I just add some CBD oil (plain flavored) to my Banana bread ejuice? Without emptying my tank or needing a second tank for the CBD?
The fact that Hemp Oil for Pain Relief comes with many benefits, as shown above, makes it impressive. Few may not afford to purchase one, but the price is okay for many customers.

Hemp Oil for Pain Relief is a valuable discovery; the manufacturers did a fantastic job. People now can get help in eradicating stress and anxiety. If you are looking for the best CBD oil, Hemp Oil for Pain Relief should be your choice.
There are likely very complex relationships also occurring between various Cannabinoids in Cannabis that may lead to certain medical efficacy. That is important to remember when considering the consumption of products that contain Cannabinoids. There is an attractiveness to isolating a specific chemical, researching it, patenting synthetic derivatives, and marketing specific drugs. That said, the relationships are complex, will likely take years to understand, and many patients I’ve met appear to find the most medical benefit from a diverse group of Cannabinoids whose interactions are not particularly well understand, but the results are hard to argue with.
You should only use CBD oil products if you are willing to accept at least some risk of testing positive on a drug test. Not everyone who uses hemp-derived CBD oil tests positive. But it does happen. The risk of testing positive is lower if you're using a broad spectrum or isolate product. These products have non-detectable levels of THC based on manufacturer testing.
As stated by Brent Brinner of Koi CBD, certain ailments mandate different rates of CBD. During his research, he noted that people who use even the best CBD vape oil incorrectly will not gain the same level of experience. You have to start low and build your way up to see what works best for your endocannabinoid system. Each of us is different and there is no real reason to start with the strongest CBD oil the market has to offer.

Reviews may be few, but all on amazon are 4-star ratings and above. Currently, there are no negative reviews for this product. The majority of consumers state that they’ve experienced significant changes to pain levels as well as better management of arthritis pain. Most reviewers are very fond of the capsule intake method, which eliminates the need to measure oil dosages.


‘In the 1940s and early 1950s, further studies showed inactivation of diverse bacteria, influenza virus, and Penicillium chrysogenum (previously P. notatum) mold fungus using various glycols, principally propylene glycol and triethylene glycol.[6] In principle, these chemical substances are ideal air disinfectants because they have both high lethality to microorganisms and low mammalian toxicity.’

I recently was a guest at a medical marijuana educational event that highlighted the work of researcher Michael Backes. During his presentation he made a statement about CBD that I have never heard anywhere else that CBD is “regulating” (my word) the effects of THC. I asked the Nurse Practitioner at the event, Ivy Lou Hibbitt of Certicann.com, what he meant by that and she said it was her understanding of Michael’s comment that he takes CBD to reduce the psychoactive effects of THC. Has this property of CBD, that it can lessen psychoactive effects, ever been researched elsewhere?
