Cunha et al. reported a 2-phase pilot study of CBD versus placebo in normal volunteers and patients with refractory secondarily generalized epilepsy (14). In the first phase, 8 normal volunteers received CBD or placebo in a doubled-blind fashion, at a dose of 3 mg/kg for 30 days. The second phase was also double-blinded in 15 patients with epilepsy receiving 200 to 300 mg daily of CBD or placebo for 135 days. Patients continued baseline AED. All subjects tolerated CBD well, with no serious adverse events. Four of the epilepsy patients receiving CBD were “almost free of convulsive crisis” for the duration of the study. Three other patients receiving CBD had a partial reduction in seizures, and 1 subject had no response. Of the 7 patients receiving placebo, seizure frequency was unchanged in 6, and 1 had clear improvement in seizure control.
Previously, I had reviewed hemp-based beauty topicals and THC beauty products pioneering the way for cannabis in the skincare industry. This time, I tested the diverse range of CBD oil-based beauty products, which are both potent and legally available for shipping to most states. This is the new frontier in skincare—and these companies are paving the way. Go support them before Sephora hears about this.

When making your decision it's important to know that not all CBD claims are as they seem! This is very relevant in the CBD niche as this is not yet FDA regulated. The FDA does tests on cbd products for sale online and publicly release warning letters to those companies who have failed to meet their claims. See the list below on which CBD brands you should probably avoid.
You are likely very familiar with the dangers that prescription painkillers (and other pharmaceuticals) present. In fact, it’s estimated that the majority of CBD oil users attempt to switch to the all-natural therapy for the precise reason of kicking prescription med habits, which all too often cause an overwhelming array of irritability, sleep disruption, digestive complications, and even thoughts of suicide.

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.
Great question! CBD can cause nausea for some individuals, particularly when they’re taking high doses. It’s odd, as CBD is also used to help people struggling with nausea and low appetite. We’re all a little different, so the responses vary too. If you’re experiencing nausea, consider taking it with food or backing down on the dose. If you want to chat with someone on our team, feel free to call us at any point or swing by one of the stores. We’re here to help!
Great question! The answer is that it depends! There are two primary types of CBD oil, isolate and full spectrum. Generally, we’d recommend full spectrum as this offers a good blend of terpenes as well as cannabidiol+. However, isolate is a better option for those who want a product with not even trace amounts of THC (in case of a drug test for their employment).
Since all pharmacologically active substances are not 100% risk-free, it is prudent to assume that even though CBD doesn’t have psychoactive effects like THC, it surely has some other effects on the body. As with all products, it is important to fully grasp the basics of what CBD does to your body (pharmacodynamics) and what your body does to CBD (pharmacokinetics.)
CBD is suddenly everywhere — and it’s not hard to see why. It won’t get you high, has a good safety profile, and naturally treats dozens of conditions. But there’s a dizzying amount of choice out there, so we’ve ranked the 25 best CBD oils to help you get started. Whether you’re a rank beginner, or you’ve been experimenting with CBD for a while, we’ve got you covered.
Over the past few years, increasing public and political pressure has supported legalization of medical marijuana. One of the main thrusts in this effort has related to the treatment of refractory epilepsy—especially in children with Dravet syndrome—using cannabidiol (CBD). Despite initiatives in numerous states to at least legalize possession of CBD oil for treating epilepsy, little published evidence is available to prove or disprove the efficacy and safety of CBD in patients with epilepsy. This review highlights some of the basic science theory behind the use of CBD, summarizes published data on clinical use of CBD for epilepsy, and highlights issues related to the use of currently available CBD products.
CBD can be expensive, especially if you’re buying good organic products that are properly tested. If a brand is spending tens (even hundreds) of thousands of dollars a year on true organic farming and state-of-the-art quality testing to ensure a great product, paying a premium is worth it. If a brand is charging a lot simply to capitalize on the hype, that’s a problem. We put together a list of the best value CBD oils we found when researching brands.
Since 2014, NuLeaf Naturals – our Editor’s Pick – has been committed to creating high-quality CBD oil products. As one of the oldest and most reviewed companies in the industry, NuLeaf Naturals has established themselves as a trustworthy CBD manufacturer. All of their products are tested by third party labs and their cannabinoid profile is impressive. They offer a unique range of concentrations for their organic CBD products ranging from 240mg to 4,850mg.
CBD oil has taken hold of the United Kingdom and it’s not showing signs of loosening its grip any time soon. The number of people using CBD oil for its health benefits doubled from 2017 to 2018, and the more aware people become of CBD products, the more popularity CBD products gain. One reason for this uptick in consumer awareness is that CBD products are sold on the high street. Holland and Barrett (a popular high street health store), in particular, introduced CBD oil in January of 2018 (Jacob Hooy CBD oil). Sadly, their CBD oil is very disappointing, and we’ll tell you exactly why in this Holland and Barrett CBD Oil Review.

Does the use of CBD oil have side effects? CBD is a natural substance, a cannabinoid from the cannabis/hemp plant, whose positive properties on the human organism are not only attributed by scientists and physicians but by people all over the world who have experienced its healing and therapeutic abilities. Even though it is a natural substance and because of the fact that we have our own cannabinoid system (endocannabinoid system), it looks as if it has been created for us, nevertheless the question arises whether CBD has side effects. And if so, which one? Under which circumstances? And at what dose?
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.

Due to my other issues, I’m extremely out of shape even though I’m not much overweight. I can’t even walk for 10 minutes without causing myself considerable pain. I do everything I can to avoid traveling in vehicles and only do so if it’s less than a 15 minute ride because it’s all my anxiety and other issues can manage. I’m only 39 and I feel like I’m not even a living person anymore and I’m sick of it. I’m desperate for a solution and mental health therapy, physical therapy, various prescriptions that have come and gone over the years have not given me much help at all. My body doesn’t react well to pharmaceutical pain relievers. I’ve been given many prescriptions over the years that I’ve stopped because they just didn’t work and they gave me weird reactions. None of those reactions were “serious” reactions, but they made me anxious and freaked me out. I’ve been prescribed several different medications over the years for my stomach issues and various nausea related issues (including Protonix, Zantac, Prevacid and Prilosec for my GERD issues, and Phenergan, Zofran and an anti-motion sickness patch I can’t remember the name of.) And I’m sick of being sick… I’m sick of taking so much nausea medication that makes me sleepy. I’m sick of being afraid of everything.
