Quality CBD oil comes from a quality source. CBD oil can be extracted from the hemp plant in a variety of ways. The safest, and most efficient methods, use carbon dioxide or ethanol as a solvent to separate the CBD from the hemp plant. All of the tinctures below are extracted from pesticide-free hemp grown on local farms in the United States, all of which are registered with their state’s industrial hemp pilot program, or organic-certified farms in Europe.
CBD has proven neuroprotective effects and its anti-cancer properties are being investigated at several academic research centers in the United States and elsewhere. A 2010 brain cancer study by California scientists found that CBD “enhances the inhibitory effects of THC on human glioblastoma cell proliferation and survival.” This means that CBD makes THC even more potent as an anticancer substance. Also in 2010, German researchers reported that CBD stimulates neurogenesis, the growth of new brain cells, in adult mammals.
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.
AZTEC CBD began producing hemp products in 2016. We are one of the first brands in the UK to offer affordable lab-tested Full Spectrum hemp products imported from the EU. Since then we have sourced the finest EU legal hemp with the best levels of CBD and set up our own fully licensed production facility in Europe – taking our products to the next level of quality and effectiveness.
Insomnia: The anxiety-alleviating and sleep-prolonging qualities of CBD oil make it a good option for many people with insomnia. Those who experience insomnia due to pain or discomfort may also find that using CBD oil alleviates their physical symptoms to a noticeable extent. CBD oil may also promote daytime wakefulness when taken in small amounts; people with insomnia can use it as a pick-me-up if they feel excessively tired due to lack of restful sleep.
Research on CBD and anxiety has generally looked at cannabis as a whole product including THC, 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.
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.
The growth of CBD Pure within the last several months has been somewhat surprising given their little-known status the first time I tried them last year. They’re not quite as potent and long-lasting as something like Premium Jane or PureKana, but like CBD Essence they’ve mostly made it this high up on the list due to their affordable prices. Believe it or not, in fact, they’re nearly 60% cheaper than PureKana on an oz-to-oz basis. If you’re just trying out CBD for the first time and want to see how it works for you before jumping to one of the more expensive brands, I’d definitely take a look at CBD Pure’s range of affordable tinctures.
Very much needed information! I’m a disabled Veteran with Anklyosing Spondelitis and related skelital/ muscle issues and CBD has been an off-limits product with the VA chronic pain clinics that dispense opiates… until recently with the addition of 0% THC – Thank you for the option!! (We actually have to sign a letter stating we will not use… else when we get tested at every appointment and THC is detected, we could be ejected from the pain clinic and our use of opiates for chronic pain!)
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.
The CBDistillery has two main strengths. The first is its variety of options. The CBDistillery offers CBD oil tinctures in a wide range of concentrations from 17mg up to 88 mg of CBD per serving. But what really sets the company apart is that they offer both full-spectrum and THC-free CBD oil options. Most people gravitate towards full-spectrum CBD oil to take advantage of the entourage effect. But with THC-free CBD oil, you can enjoy the benefits and effects of CBD even if you’re subject to mandatory drug testing.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43 percent had more CBD than indicated, while 26 percent had less, and some had unexpected THC.“There’s a 75 percent chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.
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. 
Pregnant or breastfeeding women: Because researchers don’t want to put the mother or fetus in danger, clinical studies typically don’t include pregnant and breastfeeding women. As a result, physicians can’t definitively say whether or not CBD is safe for expecting and new mothers. Not enough research has been done. However, one study did find that CBD increased the permeability of the placental barrier, which could put the fetus at risk.

Whether you are looking for CBD for general wellness or for specific medical conditions it’s important to look for these forms of lab test results; heavy metal testing, clinical trial information (if available), pesticide testing, microbial testing, potency testing, and cannabinoid profile. While having this information provided by a CBD company is important, it doesn’t necessarily mean their product will work for you. However you do not want to consider a CBD company that doesn’t provide the testing info mentioned above. Learn more about recommended best practices to look for here.


Chronic Pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
This means high doses of CBD could significantly decrease the metabolization of cocaine. In fact, a study done on mice found exactly that 11. But what they also found was that CBD only significantly decreased the metabolization of CYP substrates like cocaine, when taken in extremely high doses off 30mg/kg. Such a high CBD dose far surpasses the currently maximum recommended dose of 1500mg/day.
PlusCBD Oil is one of the few companies that doesn’t source their hemp from the United States. Although the company is working to move its hemp farming to the United States, PlusCBD Oil currently imports hemp grown in Europe. But don’t let that worry you. PlusCBD Oil is still certified by the U.S. Hemp Authority, meaning they follow high standards, industry best practices, and self-regulation.
But even though it's infiltrating pretty much every corner of the wellness world (hi, vegan CBD brownies!) many people still find CBD a little confusing—especially when it comes to figuring out the right way to use it and how to make sure the stuff you're buying is, you know, actually legit. Below, we asked experts to answer the most pressing questions about CBD.
According to Ananda Hemp’s website, it’s something of a trailblazer in the CBD world, for it possesses what it maintains to be the U.S.’ first officially authorized hemp farm. Ananda Hemp also claims to be the earliest business to have legally imported its own hemp seeds – taken from what is said to be the most extensive privately owned cannabis seed bank in the world. This, the company says, “stands in contrast to many of [its] competitors, who are sourcing questionable, non-certified and untraceable CBD sources.” In any case, people who wish to see how Ananda Hemp’s process impacts on its products can see for themselves by using its full-spectrum extracts, softgels and topical salve. Those goods have themselves, it seems, been through the testing process a minimum of three times to ensure that their levels of potency live up to what’s written on the labels.
As noted in the previous section, CBD oil prices vary significantly by brand. The best practice for most is to determine a per-milligram budget for CBD oil, as well as a maximum price for the entire bottle. For example, you might decide that 10 cents per milligram or less is a reasonable budget; and that $45 (for a 450-mg concentration, based on the budget) is a maximum bottle price. Also, if ordering online, be sure to include potential shipping costs.
The tincture is available in three strengths: 500mg, 1,000mg, and 3,000mg. Prices range from $0.04 to $0.07 per mg, depending on the concentration, which makes the tincture very low-priced compared to oils from most competing brands. Medterra also offers a 30-day satisfaction guarantee and will issue full refunds for all returns. In addition to the tincture, Medterra also offers CBD capsules in 25mg and 50mg concentrations.
Spruce was founded by Tony Spencer, who had a clear mission for his company—give people access to safe and effective lab-grade, hemp-based CBD. Spencer realized that many other CBD oils on the market were low-potency and simply didn’t work. “We have a lot of customers in pain who have wasted money on CBD products in the past that didn’t work for them,” remarks Spruce on their website.

Aside from maybe only PureKana, CW Hemp is probably the most popular CBD brand in the U.S. – at least in terms of the amount of product that they sell. And indeed they make some great, highly effective tinctures, but the only reason I don’t have them ranked higher is simply because I think they’re a bit overrated – and overpriced. If you’re into name brand reputation and will feel more comfortable buying from an established company like CW, by all means don’t be afraid to spend the money and try them out – they certainly don’t lack for quality. I just think there are other brands out there that offer better overall value for the amount of money that you’re spending.  
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.
CBD Infusionz ticks off all of the things you want to see in the best CBD oil, but my favorite thing about them is they include an updated lab report in the packaging of every product that they ship. With other brands, you’ve got to go digging through the website to view the reports, and usually they’re well outdated. Also, CBD Infusionz is a brand that puts a lot of R&D into coming up with fun, new, and unique CBD products, and I legitimately appreciate that. They’ve got stuff like hemp joints (that you can actually smoke like a regular joint), CBD chewing gum, CBD lozenges, and a variety of candies, healthy vegan edibles, pet products, and topical lotions. In fact, you’ve just got to check out their website in order to see for yourself all of the various CBD goodies they’ve got on offer.
In response to the FDA’s historic decision, the Drug Enforcement Administration (DEA) announced in September 2018 that it had removed Epidiolex from Schedule I classification, a category reserved for dangerous drugs with no medical value. Henceforth, Epidiolex would be considered a Schedule V drug, the least dangerous designation under the Controlled Substances Act.
