Generally, CBD oil is made by combining an extract with a carrier fluid or oil. This question is best answered by looking at how the CBD oil was extracted. CBD oil can be extracted using CO2 systems or by using chemical solvents. Both methods produce a CBD oil byproduct that is then combined with a fluid like MCT oil, coconut oil, or olive oil so that it can be delivered to the body. Always check to make sure you know the CBD content of the products you purchase.
These are one of the most popular (and effective) choices for arthritis and other forms of localized pain and inflammation. Since the skin acts as an excellent semi-permeable membrane that “let’s the good stuff and keeps the bad stuff out,” rubbing CBD-infused creams into the affected area has proved to be quite effective in terms of both pain and inflammation reduction.
Oils: CBD oils are the most potent and unprocessed form of cannabidiol. CBD oil is removed directly from the flowers, stalks and seeds of the hemp plant during the extraction process. The most effective CBD oils are full spectrum, which means that they include all compounds found naturally in the plant, including the cannabinoids (with trace amounts of THC), terpenes and essential oils. You can find CBD oils in a bottle with a dropper. This allows you to ingest the oil by using it by mouth.
The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors (whimsically named CB1 and CB2) in the endocannabinoid system, and each affects your body in different ways. CBD and its infamous cousin THC are the 2 most well-known cannabinoids.
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.
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.
Generally speaking, ingesting CBD oils using a dropper is typically the easiest way to stay in control of exactly how much you are taking. Plus, pure CBD oil will not contain additives that come with side effects. Remember, when you are using CBD oil or any kind of cannabis product, you must read the product label to determine the best dose for you.
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.
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. 
Cannabidiol pharmacological effects are mediated through G protein coupled receptors, cannabinoid type I (CB1) and cannabinoid type II (CB2), which are highly expressed in the hippocampus and other parts of the central nervous system (2). When activated, CB1 receptors inhibit synaptic transmission through action on voltage-gated calcium and potassium channels, which are known to modulate epileptiform and seizure activity (3). CB2 receptors are primarily expressed in the immune system and have limited expression in the central nervous system. The effects of CBD are CB2 receptor independent (3).
That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.

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].

Using rigorous review methodology, Gloss and Vickery conclude that based on the low quality of the reports available, there is insufficient data available to draw any conclusions regarding the efficacy and or long-term safety of CBD in treating epilepsy (11). From the data available, it does appear that daily doses of 200 to 300 mg were safe in this small group of patients for a short period of time (14).
A survey of patients seen in a tertiary epilepsy center found that 21% of patients admitted to using marijuana in the last year, and 24% of patients believed marijuana to be effective for their seizures (10). While interesting, this anecdotal observation does not rise to the level of evidence needed to evaluate a potential new therapeutic modality.
However, before the villainization of hemp, it was widely accepted as a very useful plant (3). From biofuel from its seeds to medicine from its leaves, it ought to be a core crop grown by farmers across the United States and beyond. However, for reasons too numerous to discuss in this article, issues of legality and federal restrictions have put a stop to that idea for the time being.
CBD oil has numerous proven health benefits. Whether you’re looking to treat your anxiety, depression, chronic pain, insomnia, or just want to feel more focused and relaxed; then CBD oil (or gummies, dabs, or a pre-filled vape pen) is the perfect choice. They even make CBD dog treats so your furry friend can get the benefits. This CBD stuff is the real deal.

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.

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. 

However, if it was sourced from actual marijuana (i.e. cannabis that contains more than 2% THC by volume), then it is technically illegal. Most of the best CBD oils for pain that you find in dispensaries in states like Colorado, California, and Washington (as well as other states where weed is legal) will have been extracted from marijuana plants — not industrial hemp plants. Unfortunately, this means that these products are not allowed to be sold online and shipped across state lines to “non-legal” states.

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.
CBD may be best known for its relaxing, calming effects. CBD reduces autonomic arousal, having the inverse effect of THC on the body. CBD’s anti-anxiety effect is why many in the cannabis community talk about how CBD relieves paranoia, although that is not scientifically proven yet. CBD is also known for its anti-nausea and pain relieving effects. It really depends on why your body’s specific needs and the quantity in which you take CBD.
The main thing that is inherently clear when scouting out FabCBD (which is a super new brand by the way that only just got started this year), is that they’ve made a pretty serious effort to develop a modern lifestyle brand. If you take a look at their website, everything from the web design to the brand labeling to the text they use screams modern and hip.

In your internet travels, you may also come across products called “terpsolates.” The manufacturers of these products infuse CBD Isolate with terpenes (but not cannabinoids like THC). These terpenes may enhance the effectiveness of CBD — or maybe they just make it smell good. This may be a good place to point out that not all CBD products are created equal. The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Third-party testing definitely helps to monitor companies’ claims, but it’s still up to you as the consumer to do your homework on the best CBD products.
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.

Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.

The interest and preference for botanical remedies such as CBD oil over harsh pharmaceuticals are growing rapidly. You can read scientific research on the promise of CBD Oil at NCBI. While North America is taking the lead legalizing cannabis and hemp the rest of the world is starting to question their stance on prohibition because of the undeniable benefits. While all talk about plant-based remedies may seem very new, using cannabis/hemp tinctures as a holistic remedy is a generations-old tradition. It was very common to use tinctures of cannabis oil in the eighteenth and nineteenth centuries. We are enjoying a renaissance in ancestral health where we are open again to remedies that were all but forgotten about in the mad race to make medicines a pill offered by a faceless often unaccountable corporation.

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.  
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.
Unlike THC, which primarily binds to CB-1 receptors located in the brain, CBD works in the body by manipulating receptors throughout organ tissues, the immune system, the pain response system, the hormonal system, and other whole-body regulatory systems. Basically, since its receptors have been found to exist in virtually every cell and tissue type in the body, CBD is believed to work on every aspect of human health and behavior – from the subcellular level to the whole-body leve and beyond.

CBD hemp oil has a number of uses and comes in many forms including capsules, tinctures, sublingual supplements, liquid oil, oil as a paste, sprays, salves, creams and in edible forms, such as candies or sweets. You can also inhale CBD oil from vapor-releasing pens, similar to the technology for e-cigarettes. This variety also provides a lot of controlled flexibility in terms of concentration, making CBD hemp oil useful and desirable for people of all ages, economic means, and personal needs.


A group of 15 patients who received CBD over a period ranging from one month to one year were surveyed to gather various data. The researchers sought information about the patient and the caregiver, changes observed in the seizures, neuropsychological effects, side effects and the family’s overall perception following the use of cannabidiol. This simple observational study identified some very encouraging findings:
The benefits of CBD don’t stop there. You may also incorporate it in your beauty products for skin care or use it for joint support after a workout. With CBD products available even for pets, you’re likely to find one that suits your needs. However, there are hundreds to choose from, which is why we put together a “buy cannabidiol” guide to empower you with knowledge to make the best decision.

Transparency: Moon Mother sends each batch of product to a third-party lab to be tested for potency as well as other contaminants. You can find all of these lab reports on the company’s website. They also added more information about their company processes to the website, so it’s easier to find important information about extraction and manufacturing.
Consume CBD oil via edibles to enjoy a sweet treat. There are many edible products available for purchase that contain CBD oil as an ingredient. These are often in the form of gummies or other candies, but also come as an edible liquid that you can mix into foods, such as smoothies. If you live in a state where it’s legal, go online and choose whichever edibles sound good to you. After purchasing, make sure to read the instructions and take them as directed.[2]

According to the largest study to date, researchers reported that after treating 162 patients with an extract of 99% cannabidiol (CBD), for a 12 week period. the intervention reduced motor seizures at a rate similar to existing drugs ( a median of 36.5 percent) and 2% of patients became completely seizure free. Other studies have shown that it can act as an anticonvulsant.
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.

Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.


Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.

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 hemp oil is the product derived from the hemp plant, which is high in CBD (cannabidiol) and low in THC (tetrahydrocannabinol). This oil has received a large amount of attention in recent years, due to the growing wave of marijuana legislation and debate in many countries, including the United States. While cannabis and smoking marijuana (which often has a high level of the psychotropic compound THC) is still illegal in many places, as more is being learned about CBD, and its potential effects on health, it is becoming more and more accepted as a legal and safe remedy for a wide variety of health conditions. Since it has a minimal amount of the psychotropic compound THC, use of this oil does not result in a traditional “high”, so its effects are generally considered therapeutic, not mind-altering.
CBD Vape Oil is very popular and can be used with a suitable vaporizer. Since this oil is generally viscous, it needs a device that can work with it. Therefore, it cannot be used with all vaporizers. Make sure you have a suitable vaporizer before using a CBD vape oil. CBD Vape oils have different concentrations and flavors. Adding terpenes also contributes to the effect.

To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases.
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.

While animal experimental data clearly suggest a potential benefit, supportive clinical data are quite sparse. In a case-control study of 308 cases of new onset seizures, Brust and colleagues found that marijuana use was significantly less prevalent among men who had unprovoked seizures compared to case controls (9). This difference was not significant in women. The authors suggest a potential protective effect against seizures with marijuana use; however, this should be considered speculative.
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?

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.

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.
