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).

Another huge benefit of CBD oil is its’ apparent effect on tumor and cancer growth. A 2006 research study published in Journal of Pharmacology & Experimental Therapeutics revealed that CBD oil potently inhibited growth of different tumor cell lines. The antioxidants present in CBD also provide anti-mutagenic properties and help lower the user’s risk of cancer. The cannabinoids compounds in the oil have the ability to directly target the cancer cells, causing a reduced spread rate and also higher cancer cell death rate.
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.

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.


CBD hemp oil has a huge range of potential health benefits and uses, including reducing pain, soothing anxiety, fighting chronic diseases, improving mood, eliminating depression, preventing inflammatory arthritis, protecting the immune system, balancing the metabolism, aiding sleep disorders, and healing the skin, among others. CBD oil can also be used in many different ways and has a variety of applications for natural health.

Gloss and Vickrey conducted a Cochrane systematic review of the use of CBD in the treatment of epilepsy (11). Their methodology included only those trials that were randomized and controlled and excluded case series, case reports, and expert opinion. They were able to identify only 4 randomized controlled studies reported in the literature, and they included a letter to the editor and an abstract. The total number of subjects enrolled in these studies was 48 (11–14). While only four studies and a letter to the editor were in the actual analysis, the authors included a complete reference listing of all articles reviewed for inclusion.

I use the Jeffrey James Botanicals 48 dollar bottle in Florida. It lasts about 3 months for me, a pretty low investment of about 16 dollars per month and all my skin problems stay at bay. No acne, no erruptions and clear smooth skin. I use a very thin film every night, the smell is also ok to be used on the face but the only problem is that I can’t wear it during the day in sunlight instead of the night one, not sure if it is ok?


Many people say that you should scrub your body with leftover coffee grounds because the caffeine helps get rid of cellulite. (It is actually well documented in medical literature.) But if you feel weird about dipping into the coffee machine at the office, try this CBD-infused coffee scrub, made with coconut oil and shea butter for extra moisturizing benefits, instead. I like using it when I need a little bit of medication with my exfoliation (which the coffee grounds are for)—plus, the strong scent of coffee will wake you up if you use it in the morning. If you live with anyone else, just make sure to clean the shower afterwards—coffee scrubs can be messy and staining.
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.
This is good news for the best CBD oil companies because the Farm Bill allows for the legal cultivation of industrial hemp, under certain circumstances, which can be a source of CBD. But CBD can also come from non-industrial hemp, namely the marijuana plant that most are more familiar with. Therefore, whether or not CBD oil for pain is legal can be a question of which “version” of the cannabis plant it was sourced from. If it was sourced from industrial hemp, (which contains less than 0.3% THC by volume), and it was cultivated under the Farm Bill, then it is legal. 

Non-THC CBD oils can be highly effective, and are suitable for employees who face random or routine drug tests. Our top pick for this category is the Medterra CBD Oil Tincture, which contains 99.6% CBD and MCT oil (also known as coconut oil extract) without any traces of THC. The oil is derived from hemp plants that are free of GMOs and pesticides, as well. All third-party testing results for the oil are accessible through Medterra’s official product page.
