CBD is the major non-euphorigenic component of Cannabis sativa. Some research is beginning to show that CBD is different than other well-studied cannabinoids. All cannabinoids function as ligands, meaning they dock onto the binding site of a protein and have the ability to modulate a receptor’s behavior. CB1 receptors are widely distributed, but are particularly abundant in areas of the brain, including those concerned with movement, coordination, sensory perception, emotion, memory, cognition, autonomic and endocrine functions.
Topical solutions: Topical CBD products include lotions, salves and lip balms. They are meant to benefit skin,  joint and muscle health, and work when they are absorbed into the skin and through the dermal layers. CBD patches are also available for topical delivery of the compound. This allows the cannabinoids to be delivered directly to your bloodstream.
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.
And lastly, don’t hesitate to speak with a marijuana doctor or health professional about using CBD oil. And please note,  it is not our goal for any of the information on here to come across as clinical advice or medical recommendations. If you live in a state with legalized medical marijuana, make sure you take full advantage of the resources that are available to you – getting a licensed MMJ card is easier than it has ever been before, and it could very well be one of the best decisions you’ve ever made for yourself.
Sub-lingual CBD drops have helped me enormously with sleeping and with radiation damage pain. I have a cancer that spread from the pelvic area to my sacrum and sciatic nerve and whilst the chemo and radiotherapy saved my life I have been taking MST (morphine derivative) for nerve pain ever since. My tumours are presently all quiet and last March I decided I wanted to stop taking the pain relief drugs, fearing dementia. CBD oil was recommended by my son who has arthritis and, for me, it really works. It’s so good to read an article that isn’t put out by a CBD sales site – I wish it could be properly prescribed and regulated (I’m in the UK) in order to have confidence with purity and dosage.
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.
Bacon had said that I might need to try two full droppers worth of the oil to really feel its benefits. I knew that I had an incredibly busy and stressful day ahead of me—I needed to fit in a five mile run before work, had lots to do at the office, was scheduled for a busy event in the middle of the day, and had a 2-hour meditation class later that night which would require a lot of mental clarity. Tentatively, I squirted two droppers of CBD oil into my bulletproof coffee and sipped away.
Is CBD Legal? Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Check your state's laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
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.
Many people are tempted to believe that products that contain CBD only are the best, thinking that using just CBD alone is a more effective treatment. While products that contain single-molecule CBD, meaning that you won’t find any other compounds, are already provided as medicines, they are not exactly more efficient than whole plant extract CBD oil, when it comes to therapeutic effects.
Hemp Bombs is based in Tampa, Florida, and in addition to focusing on the purity and therapeutic effectiveness of their products, are dedicated to establishing themselves as a top brand in the industry with a specific target audience. One of our personal favorite products of theirs is the flavored CBD vape liquids, which are some of the best-tasting CBD vape juices we’ve ever had.
The review evaluated how targeting the Endocannabinoid System (ECS) could impact colitis. The ECS is a biological system within mammals that is made up of three components: cannabinoid receptors (the things that receive chemical signals outside the cell), endocannabinoids (small molecules that activate cannabinoid receptors), and metabolic enzymes that break down endocannabinoids after they are used.
And then I woke up on the concrete, a worried crowd gathered around me. “You had a seizure,” my friend said gently as I blinked my eyes, trying to process this new information. I remember it was warm that night because I was wearing a sundress, and when I finally regained consciousness my first worry was that my dress flew up and everyone could see my underwear.
I have read about studies from Europe (not very specific I know) that suggest CBD might work better for some people if combined with some level of THC. Also, the getting high part can be helpful, although not for everybody, of course. A second point – I don’t hear very much about CBD eliminating or almost eliminating pain for people with severe pain. Helpful, but, so far at least, it doesn’t seem that CBDs can replace opioids or substantially reduce pain for all chronic pain patients. Maybe someday.
And we have a long way to go before we fully understand the relationship between CBD and pain regulation. But strong anecdotal evidence, combined with multiple lab tests and even some clinical trials, have established that CBD holds a lot of promise for pain relief. Or in science-speak, CBD “represents a novel class of therapeutic agents for the treatment of chronic pain.”
Featuring the same benefits as our pure RSHO™ hemp oil in a reduced potency, another of our midrange products, RSHO™ liquid, contains 31 mg of CBD per serving. Available in Green, Blue, and Gold Label oils, RSHO™ liquid combines our flagship RSHO™ with medium chain triglyceride (MCT) oil derived from wholesome coconut oil and sustainably sourced palm oil. Unlike RSHO™ pure hemp oils, RSHO™ liquid doesn’t need to be refrigerated, making it convenient to store wherever you need it most.
To be clear, there is no one specific test, scan, or anything else of the sort that you can do to determine whether or not you need CBD oil for pain. Also, since cannabis is not yet recognized by the FDA, you unfortunately can’t really go to your doctor either and have them recommend it; until marijuana is FDA-approved, it cannot be prescribed by physicians.
Unlike other CBD oils, PureKana really does excel in CBD oil extractions due to their unique CO2 extraction process which provides a near 99% pure CBD oil. PureKana Natural CBD Oil is an unflavored, dietary and nutritional supplement for increased health and vitality. It is extremely effective in helping to treat chronic pain, support recovery from exercise-induced inflammation, swelling, management of normal, everyday stresses, and to help promote healthy sleep cycles.

A newcomer to our CBD oils ranking, RE: Botanicals is no stranger to hemp. Founded by John Roulac, a long-time hemp advocate and founder of the organic superfoods brand Nutiva, RE: Botanicals is one of the only CBD brands to earn the USDA organic seal. They deserve a shout-out for prioritizing regenerative agriculture, while keeping prices reasonable.   


CBD can be applied to the skin both as a cream and as a concentrate or tincture. When you apply CBD Concentrate to the skin, you do not need to apply as much as the cream because of the higher concentration of CBD. Due to its gluey texture, it will adhere very well to the skin and if the CBD oil has a dark color, it will give a stain. Just leave it on as long as possible. If necessary, you can easily remove the remaining concentrate with edible oil from the skin.
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.
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.

I remember it was warm that night because I was wearing a sundress, and when I finally regained consciousness my first worry was that my dress flew up and everyone could see my underwear.

This study combats the notion that CBD causes a THC high by discussing the misinterpretations of prior studies on the subject. In fact, the researchers state that two particular prior studies “have caused much confusion and uncertainty whether oral cannabidiol (CBD) is safe and whether subjects who are treated with CBD run the risk of positive workplace tests [for THC].”
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.

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.
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.
“Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
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.
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.

Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.


Cannabidiol, more commonly known as CBD, is one of 113 known cannabinoids found in cannabis. But unlike its better-known counterpart THC (tetrahydrocannabinol), responsible for cannabis’ mind-altering effects, extensive research suggests that CBD is not psychoactive, and with none of the often-damaging side effects accompanying synthetic pharmaceuticals.


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.
CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. All 50 states have laws legalizing CBD with varying degrees of restriction, and while the federal government still considers CBD in the same class as marijuana, it doesn’t habitually enforce against it. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. Currently, many people obtain CBD online without a medical cannabis license. The government’s position on CBD is confusing, and depends in part on whether the CBD comes from hemp or marijuana. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit.
A number of difficulties exist in evaluating published data on CBD or marijuana use for epilepsy. The extremely limited published studies were small, poorly described, and not well designed. Contributing to the difficulty of interpreting published studies, CBD products are not produced under the guidance of good manufacturing practices (GMP) and are not subject to regulations governing labeling, purity, and reliability. In other words, currently, there is no guarantee of consistency between products, or even differing lots produced by the same manufacturer. Without independent testing (e.g. USP certification) of CBD products for content and purity, as well as bioavailability testing of specific products, uncertainty surrounds the use of available CBD products in routine clinical settings.
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]
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
These trichomes are tiny, hair-like crystals that cover the leaves and buds of the cannabis plant. Trichomes product the hundreds of known cannabinoids that can be found in cannabis. Of the 100+ cannabinoids that have been identified in the cannabis species, CBD and THC have been studied the most extensively for their role in the endocannabinoid system.
Ranging from irritating to debilitating, joint pain can be tricky to treat. If your pain is mild, ibuprofen or acetaminophen might be adequate. But the worse it gets, the more likely you are to be prescribed antidepressants, muscle relaxants, or even opioids. Because of the side effects associated with these prescription medications, there has been quite a bit of research on CBD and joint pain — with promising results. Here are a few studies that point to CBD’s potential:
CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a “high.” According to a report from the World Health Organization, “In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD.”
I use this for my anxiety and for my arthritis. The topical works great for my chronic neck pain. The best way to go is to get your own raw, tested material and use it in whatever form you like. It’s quite easy to make your own extract. This has worked better for me, rather than relying on a purchased, untested product – where some seem to work and others are a waste. But even with those that work, of course the cost is ridiculous and not affordable, thanks to all these corporate-pleasing laws in place, not there for the people – don’t delude yourselves.
But scientists have found that CBD doesn’t bind well with endocannabinoid receptors. Instead, CBD influences the system indirectly. This creates many benefits, which is why you’ll hear of CBD as a treatment for so many different medical conditions. And, unlike THC, it won’t make you high. When it comes to pain, we know that CBD has multiple functions. First, it influences neurotransmitters and receptors. One receptor known to be involved with pain and inflammation is called TRPV1 — also known as a vanilloid receptor. CBD binds to the TRPV1 receptor, influencing the way you perceive pain. CBD can also affect the production of neurotransmitters like serotonin and glutamate, which are related to pain sensation.
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.

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
Deciding to use CBD oil as a natural therapy is one thing – figuring out which brand to use, what strength/concentration to use, and how much CBD to actually take is another thing altogether. Plus, with all of the products out there to choose from and their confusing mL/mg labels, it can be a nightmare trying to determine which one is best for you, or which one you should be taking for your specific condition.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
And we have a long way to go before we fully understand the relationship between CBD and pain regulation. But strong anecdotal evidence, combined with multiple lab tests and even some clinical trials, have established that CBD holds a lot of promise for pain relief. Or in science-speak, CBD “represents a novel class of therapeutic agents for the treatment of chronic pain.”
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.
Take CBD oil to help treat your bowel disease. Some scientists claim that CBD and THC interact in a productive way with the bodily system that controls gut function. Because of this, people with bowel diseases, such as Crohn’s Disease, sometimes benefit from using CBD oil. If you have a bowel disease, consider taking CBD oil. It may also alleviate some of your pain.[12]
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.
