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.

CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
Cannabis oil preparations have been used historically in medicine for millennia. Only recently, cannabis and chemically-related compounds have come back to being considered of beneficial value. A prominent compound found in cannabis, CBD, or cannabidiol, has been shown to have some benefits. What is CBD oil good for? Find out all about CBD, including the extensive CBD oil benefits list, CBD oil uses and the many different CBD oil forms.
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!
There are a number of possible side effects to using CBD oil, such as fatigue, dry mouth, lightheadedness, hypotension, and impaired motor functions. However, when used in moderate amounts, most people do not experience these side effects, and none of them are known for being fatal or particularly dangerous. More than 20,000 studies have been done in the past 15 years on cannabis, hemp, and cannabinoids, and the results have been overwhelmingly supportive of the therapeutic potential and viability of CBD oil. That being said, some people should be cautious before using this powerful oil.
Here’s the thing, though—CBD oil isn’t just helpful for people with epilepsy. Turns out the oil is highly anti-inflammatory, and according to a 2013 review published in the British Journal of Clinical Pharmacology it’s also beneficial for treating anxiety, depression, neurodegenerative disorders like dementia, and even has anti-tumoral properties. Sounds like the ultimate superfood, right? I decided to give this magic oil a whirl and see if I noticed a difference in my mood, anxiety, and stress levels.
Since it started becoming popular roughly two years or so ago, the general consensus has always been that since CBD oil from top brands does not contain the psychoactive properties of THC, it is therefore legal. Unfortunately, its legality is much more nuanced because of conflicting federal laws and new court cases. What is clear is that in one of the most recent court decisions on the topic, Hemp Industries Assoc. v. DEA, which came out on April 30, 2018, the US Court of Appeals for the Ninth Circuit found that Section 7606 of the 2014 US Farm Bill (the “Farm Bill”) preempts the Controlled Substances Act (CSA), the federal law which designates marijuana as a Schedule I substance (along with heroin and cocaine) making it illegal to possess or use. This means that when there is conflict between the CSA and the Farm Bill, the Farm Bill wins out.
Another field in which CBD is creating a buzz is in the area of mood disorders like anxiety and depression. Both conditions have been treated with a variety of medications, courtesy of Big Pharma, that have had varying levels of success. Again, the long list of side effects can be off-putting to someone who just wants to get through the day without the sweaty tension of anxiety or the gray haze of depression.
I woke up seriously looking forward to my morning CBD oil fix … I mean, tonic. Truth be told, I’m an anxious person. Although I do a lot to try and calm my nerves, sometimes anxiety gets the best of me. But regardless of emotional or physical stress (I’m training for a marathon and running quite a bit!), I experienced this week, I felt a lot more in control after drinking my CBD oil tonics.  After work, I met up with a friend and felt like I could fully focus on our conversation without distractions. Could it be the CBD?
High blood pressure is a globally ubiquitous issue. This study explores the connection between CBD and a reduction in blood pressure. It is particularly unique as it is noted that “there are no dedicated studies in humans to date, to our knowledge, looking at the effect of CBD on either resting cardiovascular measurement or on the responses to stress, with continuous monitoring of CV parameters.”
Transparency: cbdMD seems to be going through a transition with their third-party testing practices. Until recently, they only released a lab report for the CBD concentrate they use for all their products, but would not show potency testing for individual products. That seems to be changing. Currently, the only lab report on the website is for their concentrate (and it’s over a year old). But if you contact customer service, they’ll send you a lab report for any product. 
Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, MD, clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger.

Other potential side effects include low blood pressure, lightheadedness, and drowsiness, but these have typically only occurred in patients who have exceeded doses of 1,500 mg daily for a period of 4 weeks or more; far more than the average person will need take on a daily basis for chronic pain symptoms. (In fact, the majority of CBD users claim they find an effective dose to be anywhere between 10 and 40 mg daily).

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.

Find the right CBD to THC ratio for you. Some people enjoy the high that THC provides, while others feel undesirably “out of it” when they use products with significant amounts of THC. No single ratio works for everyone, so experiment with a few different ones until you feel that the product you’re using is working well and helping you. You can also choose a ratio based on what you’re hoping to achieve with the use of CBD oil.[7]

CBD is a chemical found in marijuana. CBD doesn't contain tetrahydrocannabinol (THC), the psychoactive ingredient found in marijuana that produces a high. The usual CBD formulation is oil, but CBD is also sold as an extract, a vaporized liquid and an oil-based capsule. Food, drinks and beauty products are among the many CBD-infused products available online.
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.
Several weeks after a hysterectomy last spring, Bo Roth was suffering from exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture.
Based in Los Angeles, Calm by Wellness plans to be among the largest hemp-growing and CBD extraction facilities in the world by the end of 2019. The company sources their hemp from Colorado and uses clean CO2 technology to extract their CBD and other cannabinoids (no THC though!). The company is also GMP and ISO9001 food-grade manufacturer certified.
Research on CBD and anxiety has generally looked at cannabis as a whole product, not as CBD as a standalone compound. Some studies suggest that it can help with anxiety: like this 2011 study that suggests CBDcan reduce social anxiety or this 2015 review that says CBD could be promising for many forms of anxiety. It’s also important to consider whether the CBD comes from the cannabis plant and therefore may include THC, a cannabinoid that for some, induces anxiety. Read our comprehensive article on CBD and anxiety, here.
CBD hemp oil has a huge range of potential health benefits and uses, including reducing pain, soothing anxiety, fighting chronic diseases, improving mood, eliminating depression, preventing inflammatory arthritis, protecting the immune system, balancing the metabolism, aiding sleep disorders, and healing the skin, among others. CBD oil can also be used in many different ways and has a variety of applications for natural health.

Unfortunately due to the disappointing and down right inaccurate position of the federal government in classifying Cannabis as a schedule one drug, most research institutions risk federal funding if they conduct real research on Cannabis. This has dramatically limited the potential for real research by real scientists to be conducted. That research is critical to better understanding the multitude of therapeutic effects of the various chemical constituents found in Cannabis.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
Pharmacology published a study in 2016 looking at medical marijuana for migraines, specifically in relation to its effects on serotonin, with very positive results. You’ll notice that neither study looked at CBD in isolation from other cannabinoids (which is an issue with a lot of research on CBD and pain). Truthfully, the research on CBD alone just isn’t sufficient to make any pronouncements about its effects on headache pain.
Truth be told, one of the biggest draws to using CBD oil for pain has been the fact that it has little distinguishable side-effects or contraindications with other medications. In fact, in a massive report that was published by the World Health Organization during last year’s 2017 Expert Committee on Drug Dependence, it was (finally) declared to the world that CBD is a “safe, well tolerated [compound, which] is not associated with any significant adverse public health effects.”
Like we said, once you start using CBD oil more frequently and are able to gauge how much you need to find relief or therapy, then you can jump up to the more high-potency products as needed. For reference, doses will typically range anywhere from 5 mg to 100+ mg in a single day. And for epilepsy patients, they may take anywhere between 300 mg to an entire gram (1,000 mg) per dose — or more!
Of course, though, they offer less potent oils than that, with a product lineup that ranges from 300 mg CBD per bottle to 4,000 mg. Naturally the 4,000 mg option is the most expensive (this is the one that provides the “bomb” 60 mg dose), as it currently sells for $299. For long-term pain and anxiety relief, though, it may be well worth it if it is effective for you and helps replace your regular meds.

Scott Shannon, MD, assistant clinical professor at the University of Colorado, recently sifted through patient charts from his four-doctor practice to document CBD’s effects on anxiety. His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says. But he says he can’t discount a placebo effect, especially since “there’s a lot of hype right now.”


Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.
As the CBD Pure Hemp Oil label warns, you should not take the supplement if you are breastfeeding or pregnant, as there isn’t enough information on how it could affect the baby. Also, some studies suggest a long-term heavy use of cannabis can have negative neuropsychologic and behavioral effects, and even cause acute pancreatitis, although the exact mechanisms are still unknown.

When it comes to using CBD, questions keep coming up, especially from people who try CBD for the first time. Since there are different CBD products and because CBD can be used in different ways, the question of how to use CBD oil is quite legitimate.  What CBD products are available, how they can be used, and the bioavailability of each product is covered in this article.


For those customers looking to balance cost and potency, three of our popular brands, RSHO™, Dixie Botanicals®, and Cibdex®, carry a line of CBD hemp oil capsules with a moderate 25 mg of CBD per capsule. These medium potency capsules contain the same CBD hemp oil as our other products, making it simple to take your CBD supplements with you. These bottles fit easily into an overnight bag or briefcase and are never out of place in a bathroom medicine cabinet or office drawer, ensuring your CBD hemp oil supplements are within reach.

Simply place the CBD Vape Oil in the designated tank (cartridge), turn on the vaporizer, and smoke the CBD vapor. The great thing about taking CBD vaporized is that it works very fast. The bioavailability is very high, which means that a very large part of the CBD being used is absorbed by the body. The CBD gets into the bloodstream very fast through the absorption in the lungs.

There is a strong sedative quality to CBD hemp oil, making it a popular remedy for people with insomnia, sleeplessness, interrupted sleep, post-traumatic stress disorder, restless leg disorder, and other night-time issues. Dr. Scott Shannon, Assistant Clinical Professor of Psychiatry at the University of Colorado School of Medicine, USA, published a report in the Permanete Journal, in which he recommended either inhaling a small amount of CBD oil, applying it to one’s chest, or even putting a few drops on one’s pillow to help get a good night’s sleep.
In one survey, parents of children who suffer from treatment-resistant epilepsy and use CBD were asked about the benefits. 19 parents were included, 84% of which said that CBD reduced the frequency of seizures. Two parents said that CBD completely resolved seizures. Parents also reported improved alertness, sleep, and mood. Some side effects were drowsiness and fatigue [54].
This isn’t new but had to be mentioned. One of the major and well-known benefits of cannabis is its ability to treat pain and helping with pain management. It has the capabilities of assisting with chronic pain as well as inflammation. Furthermore, it has been found to help patients deal with severe rheumatism and arthritis as well as other chronic pains.

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.


This is why Amanda Oliver, 31, a career consultant in Charleston, SC, pops a CBD gummy bear each night before bed. “I used to lie there tossing and turning as my mind raced from work projects to whether I had set the home alarm,” Oliver says. One piece of candy with 15 milligrams (mg) of CBD is enough to shut off her brain and facilitate sleep. She also swears by the CBD oil she takes at the height of her period, which she says quells her debilitating cramps.

It makes no sense to me that something that helps with anxiety has an irritability side effect – as a lot of my anxiety is co-mingled naturally with irritability. Further, I have noticed none of these side effects, given that if you become fatigued or sleepy, you adjust dose the next day. So I don’t call that a side effect – rather – an effect of taking too much.

Customer Service: We’ve always received fast, informative responses to our queries about products and practices, but there are definitely customers out there who have not. A quick perusal of reviews shows customers who had issues with unaddressed orders. It’s hard to know exactly what the problem is in these situations, but the company’s strict return policy (seven days for unopened products only) probably doesn’t help. It should be noted that the company has a solid base of very satisfied customers as well.
Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, PhD, director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”
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.
A natural plant extract, CBD (or cannabidiol) has made a huge stir in the health scene over the last decade. It’s not hard to find plentiful anecdotal evidence of its benefits — people are using CBD for pain relief, mood regulation, cancer prevention, even seizure reduction. But if you’re in pain, you’re probably looking for more than anecdotal evidence. We get it — and we’re here to help.

Vape oil: CBD vape oil is used for vaping CBD. This requires the use of an e-cigarette or vape pen, which can have side effects when chemicals are heated to high temperatures. There are also CBD waxes available that are used for dabbing the cannabis compound. This also requires heating a small amount of the wax and using a dabbing pen. This isn’t recommended for beginners, as it’s usually a higher concentration of CBD.
All this talk about THC lands us nicely in the whole “Full Spectrum vs. Pure Isolate” debate. Once you begin shopping for CBD products, you’ll notice a lot of jargon that gets thrown around without much explanation. Now that we’ve introduced THC into the conversation, we can talk about the difference between, and relative benefits of, Full Spectrum CBD and CBD Isolate (and the lesser-known contender: Broad Spectrum).

The human body has an endocannabinoid system — a natural system that maintains homeostasis or balance, in the body. The endocannabinoid system has CB1 and CB2 receptors. These are found throughout the body. CB1 receptors are generally located in the central and peripheral nervous system and CB2 receptors are generally found in the brain, immune system, and gastrointestinal system. CBD binds to these receptors creating changes and effects in the body
