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.
Generalized pain, for instance, has dozens upon dozens of high profile research and clinical studies that have been carried out in universities and laboratories around the globe. One of the most well-publicized of these studies took place back in 2008, in which results determined that “cannabinoid analgesics (pain relievers) have generally been well tolerated in clinical trials … with acceptable adverse event profiles (meaning acceptable effectiveness for practical use).
Researchers at the Department of Pharmacognosy, The School of Pharmacy, University of London, UK, basis the study conducted on mice found that CBD oil has analgesic properties and may relieve chronic pain of all kinds . It can disrupt the activity of pain receptors in the body and instead cause a release of neurotransmitters such as serotonin and dopamine – “feel good” compounds that can ease discomfort and pain, even if the pharmaceutical painkillers have no effect.
Statement from FDA Commissioner Scot Gottlieb, M.D., on signing of the Agriculture Improvement Act and the agency's regulation of products containing cannabis and cannabis-derived compounds. U.S. Food and Drug Administration Web site.

During period, women usually experience alot of pain due to menstrual cramps. The cramps begin up to a week before the period starts, and can continue during and even after the period is over. This is a terrible situation and can affect some women so severely such that it can make it difficult for them to go about with their daily activities. Fortunately, cannabidiol oil can help alleviate the feeling of the menstrual cramps and can allow them to get back to their day to day life.
However, switching to CBD oil from a conventional medication is far from a random stab in the dark. In fact, there was a large scale (and very well-documented) survey carried out less than two years ago that looked at precisely what percentage of patients were able to “swap” their side effect-inducing meds for a 100% natural, cannabis-based therapy.
Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. But cannabidiol seems to prevent the breakdown of a chemical in the brain that affects pain, mood, and mental function. Preventing the breakdown of this chemical and increasing its levels in the blood seems to reduce psychotic symptoms associated with conditions such as schizophrenia. Cannabidiol might also block some of the psychoactive effects of delta-9-tetrahydrocannabinol (THC). Also, cannabidiol seems to reduce pain and anxiety.

Having 1 organic certification is hard enough. BioBloom possesses 3: the Austrian, Swiss and Hungarian Bio certificate and the British Biodynamic Association one, making it the only Cannabidiol product available in the UK with a triple organic certification. This means that from the moment it was planted in the organic soils of an Austro-Hungarian riverbed to the moment it reaches the bottle, the entire process is supervised and tested certified organic. No machines are allowed in the hemp farms and the entire process of harvesting and drying the cannabis plants is done by hand. This is a remarkable product with a very strong taste (perhaps the strongest of all oils we’ve tried), which in our eyes means it is full of goodness. Visit the BioBloom collection.


Their 350 mg CBD is the original broad spectrum oil that started it all for this company. Green Road’s oil is infused with the highest quality pharmaceutical quality naturally occurring cannabidiol. It is a vegetable glycerin based olive oil which is vapeable and sublingual. This powerful oil is American made by an experienced licensed pharmacist. It is quality you can trust.


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.

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.
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.
If your intention is to help treat chronic pain, then you may want to start out with a lower dose, and then proceed from there. If you notice effective results, you can downsize the dose, or likewise you can always up the dose until positive results are achieved. The key is to only increase your dosage in small increments so that you are able to pinpoint exactly how much CBD oil it takes to treat your condition. Be advised, though, that you should not exceed the recommended daily doses that are listed on the bottle and you should consult with a physician.
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.

If one takes high amounts of CBD, the cannabinoid can temporarily neutralize the activity of P450 enzymes and thus alter the way drugs are metabolized inside the body. This action of CBD can be regarded as a side effect, but it’s not always a negative trait, as the deactivation of P450 enzymes is one of the mechanisms through which CBD neutralizes THC as well.
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.
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 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.   
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.
To my understanding, neither CBD nor THC are effective for “severe” pain; rather, they work better for mild to moderate chronic pain. Often, with severe pain, the dosage of opiates can be decreased with concomitant use of medical cannabis or CBD and that decrease in dose makes their use safer. Concurrent use of THC does increase the analgesic effect of CBD, but it also adds the “high” which some people do not want as a side effect.
Customer Service: It’s difficult to find contact information on Calm by Wellness’s website, and their email address is listed incorrectly in two places (we tried sending them an email but it was not delivered). We were, however, able to get a response through Facebook, and the company does offer free shipping and a generous 30-day return policy on all orders.

The short answer is no, you do not need a prescription for CBD oil. No prescription or doctor is needed to purchase any CBD products that do not contain THC. THC is the psychoactive compound in marijuana. However, CBD oil is derived from the hemp plant which contains minuscule amounts of THC (less than 0.3%). Some states legalized the purchase and use of CBD oil containing THC and in those states, you are not required to have a doctor’s prescription.
All things considered, the future looks pretty bright for this company. Judging by the results of our Koi CBD review, the sheer quality of its products means it deserves its success. Management clearly understands the need for transparency in an industry that isn’t well regulated, and we applaud their decision to publish the results of Koi CBD oil lab tests on the website (and certainly wish other CBD sellers would follow suit).
[…] I have recently partnered with Elixinol through their affiliate program. Elixinol is an online based CBD product company out of Colorado that makes their products from CBD that has been procured from industrial hemp. Elixinol does a wonderful job of being transparent about their product lab results and side effects of CBD. On their site, you can find a great write-up on the side effects of CBD. […]
Because of the strong results of several of these studies, at least one major clinical trial is currently in the works. The trial, conducted by researchers at New York University, will test whether CBD can help people with PTSD deal with alcohol addiction. The results of clinical trials like these will determine whether CBD moves into the mainstream of PTSD treatment.
This method proved successful for years, but high-strength concentrates would sometimes crystallise and clog the very small orifice through which the oil was to be delivered. Recognising the issue and the fact that most customers needed a higher dose to be delivered quickly, CannabiGold further developed its packaging to launch a side nozzle. This pump can deliver a higher dose of the oil (4 times what it used to) in one go and do it very easily under the tongue, without having to use a mirror to ensure one is getting the right number of drops. The easy dropper technology has boosted the good reputation of the already popular cylinder bottles because they’re easy and safe to use wherever you go with no leaking and a very convenient pocket size. Each of their 12ml bottles now contains 100 pumps (full doses) of CBD, making it the easiest and most convenient system available, truly suitable for all use, including travel. Visit the CannabiGold collection.

Hemp Bombs are all about feeling great and relaxing. Other CBD oils can’t compare with the potent dose Hemp Bombs provides. Other oils typically give you around 6 mg of CBD in each serving whereas Hemp Bombs’ maximum strength CBD tinctures are designed to be taken sublingually and give an enormous 60 mg dose of CBD in one dropper (or 20-30 mg with a few CBD oil drops). They do however provide other oils with less potency, so there is something for everyone. Hemp Bomb oils range between 300 mg of CBD to an incredible 4,000 mg per bottle.


The key is to effectively gauge exactly how much CBD oil it takes to start managing your pain. If you start off right away with a maximum dose of a 600 mg tincture, you will have no idea how much of the product it actually took to treat your condition, and how much you wasted (this is also important because you do not want to exceed dosage and end up developing a tolerance to the active cannabinoids).
Common treatments for fibromyalgia are anti-inflammatory medications, opioid pain medications, and corticosteroids. A 2011 study that focused on CBD treatment for fibromyalgia produced very promising results for future uses in treatment. Half of the 56 participants used Cannabidiol, while the other half used traditional methods to treat their condition. Those that used cannabis saw a great reduction in their symptoms and pain, while those using traditional methods didn’t see much of an improvement.
CannabiGold was formulated by HemPoland but has recently been acquired for $15.5 million by The Green Organic Dutchman Holdings Ltd. (TGOD). On top of that, they’ve invested another $10 million in the development of the company. This is the largest cannabis oil Europe has seen yet. CannabiGold’s CO2 extracted oil comes from 1,250 acres of hemp fields in Poland and is widely distributed to 13 countries in Europe, namely: Poland, Austria, Netherlands, Germany, United Kingdom, Italy, Switzerland, Portugal, Ireland, Czech Republic, Slovenia, Lithuania, and Estonia. CannabiGold is one of the only companies in Europe with more than 700 bricks and mortar sales locations. Their goal is to be number 1 in Europe and it seems that they may make it! Founder and CEO Maciej Kowalski reached the peak of success by methodically researching, testing, and improving their full-spectrum CBD oils, which range from the starter 500mg to the strong 3000mg CBD oil. The latter comes with a free product gift and free priority delivery if you purchase it at for the Ageless. CannabiGold also features 1000mg (CBD and CBDa) and 1500mg oil.
There are likely very complex relationships also occurring between various Cannabinoids in Cannabis that may lead to certain medical efficacy. That is important to remember when considering the consumption of products that contain Cannabinoids. There is an attractiveness to isolating a specific chemical, researching it, patenting synthetic derivatives, and marketing specific drugs. That said, the relationships are complex, will likely take years to understand, and many patients I’ve met appear to find the most medical benefit from a diverse group of Cannabinoids whose interactions are not particularly well understand, but the results are hard to argue with.
Majority of cannabinoids have been shown to have positive effects on the immune system, particularly the CBD oil, as it helps regulate over-active immune systems. This basically means less susceptibility to various kinds of allergens. Moreover, since CBD oil contains a high amount of omega 3 which supports the growth of micro organisms which live in the intestines, it can aid in enhancement of the immune system, and your body will be able to fight flu, illnesses and germs more easily.
CBD oil comes in a variety of strengths, so it’s important to pick a suitable strength to help with your anxiety. The CBD oil produced by CBD Pure is our preferred solution for reducing and relieving anxiety symptoms. Their oil is made using natural ingredients (sourced from organic hemp) and they even provide a 90-day money back guarantee, so you have nothing to lose.
At the top of our ranking is Portland-based Lazarus Naturals, which has honed a reputation for high-quality, affordable CBD. Their consciously crafted CBD is sourced from organic, Oregon-grown hemp which the company controls from seed to sale. With low prices, a robust assistance program, free shipping, and a 30-day, no questions asked return policy, you really can’t go wrong with Lazarus Naturals.

However, even if you do suffer from one of the above-mentioned chronic conditions, it’s still recommended you start out with the low potency oil first, at least until you gauge how your body reacts to the CBD. It’s important to understand that because everybody’s biochemistry is different, not everyone will react the same or get the same therapeutic effects from CBD oil.

For epilepsy: A prescription cannabidiol product (Epidiolex) has been used. The recommended starting dose is usually 2.5 mg/kg twice daily (5 mg/kg/day). After one week the dose can be increased to 5 mg/kg twice daily (10 mg/kg/day). If the person doesn't respond to this dose, the maximum recommended is 10 mg/kg twice daily (20 mg/kg/day). In some research, higher doses of up to 50 mg/kg daily have been used. There is no strong scientific evidence that nonprescription cannabidiol products are beneficial for epilepsy.


Currently, the only CBD product approved by the Food and Drug Administration is a prescription oil called Epidiolex. It's approved to treat two types of epilepsy. Aside from Epidiolex, state laws on the use of CBD vary. While CBD is being studied as a treatment for a wide range of conditions, including Parkinson's disease, schizophrenia, diabetes, multiple sclerosis and anxiety, research supporting the drug's benefits is still limited.
Scientists at the Cajal Institute used animal models and cell cultures to find that Cannabidiol reversed inflammatory responses and served as durable protection from the effects of multiple sclerosis. Mice with 10 days of CBD oil treatment had superior motor skills and showed progression in their condition. Using this information, researchers concluded that CBD has the potential ability to reduce various aspects of MS.
As always, KOI CBD ensures that the product contains 0% THC. All in all, this would be a good option for anyone who suffering from skin irritation, or perhaps even from a joint pain condition such as rheumatoid arthritis. Simply rub the Koi CBD lotion on the affected area a couple of times a day, and what for the action of the natural cannabidiol to kick in.

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.
