The furry subjects, 277 Wistar rats, were given a dose of CBD immediately after receiving a small electric shock. The CBD-treated subjects were found to spend less time frozen in fear when reintroduced to the context of the fearful event. This means the CBD disrupted consolidation (or more simply put: memory strengthening) of their specific and long-term fear memory.
Although it is great that you have compiled a long list of the best CBD oils, so that we get some choice also as consumers, however, I rely believe in your well researched information that you share always, and so I feel the number 1. you shared, Purekana is going to make the choice for me. Ordering it tonight, and let’s see how my CBD journey goes from here. A bit nervous though!
Another point worth clarifying is the difference between hemp seed oil (or hemp oil) and CBD oil. There’s confusion on this point for the very good reason that both CBD oil and hemp seed oil are extracted from the industrial hemp plant. But there’s a big difference between the 2. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things — it’s good for you, tastes great, and can be used in soap, paint — even as biodiesel fuel.
When administered alone, CBD is an effective anticonvulsant in maximal electrical shock (MES), magnesium-free, 4-aminopyridine, and audiogenic models (7, 8). Co-administration with AEDs leads to various effects; anticonvulsant effects of CBD are enhanced with phenytoin or phenobarbital but decreased with chlordiazepoxide, clonazepam, trimethadione, and ethosuximide. In a recent study using an acute pilocarpine model, although CBD administration reduced the number of animals displaying seizure activity, CBD did not appear to have any significant effect on the number of seizures per animal (7).
Numerous studies have found results that confirm the ability of marijuana to help anxiety and stress. In 2013 an Israeli study demonstrated that treatment with cannabinoids helped to control emotional responses and prevent stress-related responses for those that had experienced a traumatic experience. In 2015 a group of researchers found that cannabis treatments were effective in reducing anxiety in those suffering from PTSD.
CBD works by attaching itself to specific receptors of the body’s own endocannabinoid system. The human body is known to produce cannabinoids of its own, which affect the cannabinoid receptors CB1 and CB2. The CB1 receptors are generally found in the brain, and deal with pain, mood and emotions, movement, appetite, among others. THC acts upon the CB1 receptors. Meanwhile, CB2 receptors are more commonly found throughout the immune system, affecting inflammation and thus pain. CBD is thought to act upon these receptors, by influencing the body to produce its own cannabinoids in order to rebalance itself.
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.
Of course, there is a different side to the story also. It is true that the studies concluded so far have their limitations, and there is no saying what effects supplementation with CBD for more than 6 months could have. However, they suggest cannabidiol has the potential for treating some mental disorders, like anxiety and depression, seizure disorders like epilepsy, insomnia, and chronic pain.
While it is still classed illegal on a Federal level, individual U.S. states have adopted a more lenient policy towards this plant and some states now allow it for recreational use. The easing up of state laws has also allowed researchers to explore this miraculous plant and only recently has it been found to be an effective treatment for a variety of medical problems due to its CBD oil benefits. From cancer, anorexia, pain and inflammation management it seems like medical marijuana is placing a strong footing within the medical industry.
If this is not sufficient for calming your symptoms, a gradual increase of another 25 mg per day, over the course of 3-4 weeks, is recommended. While there have been no reports of more serious side effects when this oil is taken in larger concentrations, it is best to slowly increase your dose to find a comfortable and effective level, given your individual characteristics and needs.
Although several clinical studies focused on the health effects of CBD, the results available so far were not enough to convince the FDA to approve it as a drug. The FDA does not agree with its use as a dietary supplement either, but as long as sellers publish the appropriate disclaimers (like those on the CBDPure website and labels), it’s not up to them.
It’s safe to say that Charlotte’s Web is probably the most recognized CBD brand out there — and it’s not all hype. This company pioneered the CBD industry and made it their mission to de-stigmatize CBD by setting the bar high for transparency. They produce and oversee their organic CBD products from seed to sale, standing behind them with a solid return policy.
