Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a “high.” According to a report from the World Health Organization, “In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD.”
The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors (whimsically named CB1 and CB2) in the endocannabinoid system, and each affects your body in different ways. CBD and its infamous cousin THC are the 2 most well-known cannabinoids.
Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
Pharmacology published a study in 2016 looking at medical marijuana for migraines, specifically in relation to its effects on serotonin, with very positive results. You’ll notice that neither study looked at CBD in isolation from other cannabinoids (which is an issue with a lot of research on CBD and pain). Truthfully, the research on CBD alone just isn’t sufficient to make any pronouncements about its effects on headache pain.
Based in Los Angeles, Calm by Wellness plans to be among the largest hemp-growing and CBD extraction facilities in the world by the end of 2019. The company sources their hemp from Colorado and uses clean CO2 technology to extract their CBD and other cannabinoids (no THC though!). The company is also GMP and ISO9001 food-grade manufacturer certified.
As mentioned above, CBDPure is a natural oil extracted through cold pressing and CO2 procedures from Cannabis sativa. Specialists have identified over 80 compounds known as cannabinoids. Their research so far showed that CBD is the predominant cannabinoid, accounting for over 40% of the cannabinoids concentration. It is also the most beneficial for human health, at least from the cannabinoids studied so far.

Cannabidiol, or CBD for short, is a phyto-cannabinoid found in cannabis plants. However, it does not cause the same psychoactive effects as other naturally occurring cannabinoids (such as tetrahydrocannabinol, or THC). CBD induces feelings of sleepiness and tranquility, making it suitable for insomnia and other sleep disorders; CBD can be used to alleviate symptoms of epilepsy, diabetes, and anxiety disorders, as well. Legality is an issue for some; all 50 states have laws governing the sale, possession, and use of CBD, and they vary significantly (see the table below for a full analysis).
High-potency CBD oils are most suitable for people experiencing strong, insomnia, chronic aches and pains, anxiety/depression symptoms, and other conditions that necessitate stronger effects. Our top pick for this category is the Lab Grade CBD Oil from Spruce, which comes in a 30mL bottle with a concentration of 2,400mg. Each full dropper of oil contains roughly 80mg of CBD, which can be an effective dose for those with severe discomfort or symptoms.
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.
The human body also produces cannabinoids, known as endocannabinoids, in a bodily system known as the endocannabinoid system (or ECS). The ECS promotes homeostasis by regulating a wide range of functions, including motor skills, mood, appetite, and sleep. As we age, our ECS produces fewer endocannabinoids; they may also decrease due to physical injury or disease. Replenishing depleted endocannabinoids with phytocannabinoids like CBD can help restore balance to the body.
CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $22 billion by 2022, per the Chicago-based research firm Brightfield Group.

Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.
