On the down side, free shipping kicks in at $100 — otherwise it’s a pricey $9.99 flat rate. And you can return products, but only if they’re unopened.
More human studies are needed to fully understand the range of risks and side effects that CBD oil may cause. Studies of CBD oil aren’t common. This is partially because Schedule 1 substances like cannabis are highly regulated, causing some obstacles for researchers. With the legalization of marijuana products, more research is possible, and more answers will come.

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.

Since 2014, NuLeaf Naturals – our Editor’s Pick – has been committed to creating high-quality CBD oil products. As one of the oldest and most reviewed companies in the industry, NuLeaf Naturals has established themselves as a trustworthy CBD manufacturer.

They offer a unique range of concentrations for their organic CBD products ranging from 240mg to 4,850mg.
A study from 2016 worked with 214 people with epilepsy. The study participants added oral doses of 2 to 5mg of CBD per day to their existing anti-epilepsy medications. The study’s researchers monitored the participants for 12 weeks, recording any negative side effects and checking on the frequency of their seizures. Overall, participants had 36.5 percent fewer seizures per month. However, severe adverse effects were recorded in 12 percent of the participants.

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.
We’ve linked to the best, most reputable source for each one of these products (most frequently the manufacturer’s site). While you may want to shop around (and we encourage it!), we recommend that you buy from one of our preferred sites. That way you’ll know that you’re getting an authentic product at a reasonable price, from a company that actually stands behind their product.
It’s also important to select CBD oil products based on your concentration preferences. Some forms of CBD oil – such as vapors and tinctures – normally have higher-than-average concentrations, whereas sprays and topicals tend to have lower concentrations. Remember: higher concentration means more pronounced effects, but not necessarily mean higher quality.
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.
Vaporizers – Many state-licensed cannabis dispensaries offer high CBD strains of cannabis flower. This allows for reduced risk of paranoia while allowing for a high medicinal dose of CBD. Vaporizers are used to heat up the flower and remove the properties or compounds of the plant that you are looking for without combustion or smoking. Vaporizers use convection much like a convection oven.
There’s still a lot of unknown territory, but early evidence for CBD’s efficacy is more than enough to justify further large-scale clinical studies — some of which are already in the works. These studies also point to the variety of effective ways to take CBD. This is an important point to keep in mind if you find yourself shopping for CBD products and wondering if the best CBD for pain is a topical, a tincture, or a vape product.

Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.


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.
