Just last year, Herbivore launched Emerald, a hemp-infused oil, and a few months later, it's unveiling its CBD-infused twin. Like the original, the new Herbivore Botanicals Emerald 100mg CBD Deep Moisture Glow Oil formulation packs a hydrating punch, but also provides the calming and soothing effects of the ingredient. Plus, the brand will donate $1 from every Emerald sale to support cannabis legalization efforts as well as female-owned organizations in the cannabis industry.

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].


CBDPure is derived from organically grown hemp plants in Colorado. Popular amongst reputable CBD brands is their risk-free 90 day money-back guarantee. They utilize CO2 Fluid extraction to ensure their CBD contains only full spectrum cannabinoids. CBDPure Hemp Oil contains no added colors or flavors. CBDPure offers 100, 300, and 600mg bottles of pure CBD oil. One drawback to CBDPure is they only offer tinctures (edit: they just added gelcaps) which cap out at 600mg per bottle. If you're looking for something stronger you'll want to move down this list.
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).

Customers should always request third party lab results that test for potency, pesticides, residual solvents, and mycotoxins of the CBD hemp oil. If a company is reluctant to share these results with you, it should automatically be a red flag and indicate that they have something to hide. We’ve done the work and checked if these brands offer those tests to their customers. We’ve assigned a letter grade of C, B, A, or A+ based on what kind of lab results are offered to customers. All the brands on this list at least offer tests showing the levels of CBD and THC in them (with THC under the legal limits for hemp of 0.3%), but brands which go further are rated higher.

Some studies have investigated the role of CBD in preventing cancer cell growth, but research is still in its early stages. The National Cancer Institute (NCI) says that CBD may help alleviate cancer symptoms and cancer treatment side effects. However, the NCI doesn’t fully endorse any form of cannabis as a cancer treatment. The action of CBD that’s promising for cancer treatment is its ability to moderate inflammation and change how cell reproduce. CBD has the effect of reducing the ability of some types of tumor cells to reproduce.

Because of the negative notions connected with the use of marijuana and cannabis, research on CBD is strongly constrained. Though, some research acknowledge that CBD can alleviate certain conditions. A study is being made on the extraction process of CBD from the plant whether to use the whole plant or just a part of it. The benefits taken from CBD is greatly affected by the extraction process.


Cannabidiol is the major nonpsychoactive component of Cannabis sativa. Over the centuries, a number of medicinal preparations derived from C. sativa have been employed for a variety of disorders, including gout, rheumatism, malaria, pain, and fever. These preparations were widely employed as analgesics by Western medical practitioners in the 19th century (1). More recently, there is clinical evidence suggesting efficacy in HIV-associated neuropathic pain, as well as spasms associated with multiple sclerosis (1).
The important thing is that you have to be SUPER careful when selecting CBD oils. Since the cannabis industry is not FDA-regulated, there have been dozens and dozens of companies trying to get away with selling very low quality (and even potentially toxic), “snake oils” that have been extracted using harsh chemical solvents like butane and hexane. Make sure you stay away from cheap products like these, as they could damage your health.
Great points and thanks for the clarification. To be clear, THC products are not readily available to purchase online (legally), so anyone hoping to try the CBD oil trend will have to settle for these alternatives for the time being, until the FDA approves more variations. Many people who are new to CBD see these options as a good entry-point before they experiment with larger mg amounts, and the reviews online are strong. Still, you are correct that full spectrum CBD oils may ultimately be better once they are legally approved to sell online to everyone.

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. 


This unit will have to go into its own category as not many cbd merchants sell a pure hemp extract. After speaking with the owner of Pure Science Lab, Steve, he mentions that they sell the pure extract made from pure cbd spectrum vs cbd isolate to both manufacturers as well as consumers. A few of our reviewed brands even use his extract to make their tinctures, edibles and more. With 41% CBD per gram (or 410mg total), this pure high-potency CBD concentrate is one of the best products available for sale, and is indeed, the strongest full spectrum CBD you can buy. It also comes in multiple packs as well as in 5g applicators. Committed to quality and third party testing, Pure Science Lab’s CBD extract is great to use directly under your tongue or create concoctions of your own.
Dry Mouth: As is the case with many other hemp- and marijuana-based products, CBD oil often leads to a condition known as dry mouth (or cottonmouth). This is likely due to cannabinoids altering receptors in the lower jaw that trigger salivation. In most cases, mild discomfort and stronger-than-average thirst are the only issues associated with dry mouth.

Dispensaries: In states where marijuana is legal for recreational use, dispensaries are a common sight. They are much rarer in states with more restrictions. In states that permit the use of medical marijuana, hemp-based CBD oils do not normally require a prescription but marijuana-based oils do. Like brick-and-mortar locations, dispensaries offer more customer service. However, as noted, this may not be an option depending on the buyer’s state of residence. Also, CBD oil prices tend to be significantly higher at dispensaries.
Vape Pens – Perhaps the easiest way to get the CBD Oil into your body is through a vape pen. A vape pen is about the size of an ink pen but has a CBD oil cartridge with a heating element. Many people like vape pens because there is very little in the way of odor after using it and it allows for a lot of discretion because it can be pulled out of your pocket and used on demand.
