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.
CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.
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.
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.
Improving the appearance of the skin, especially reducing the signs and symptoms of acne and eczema, are the great benefits of regular CBD oil use. Topical application is quite popular for this, whether in a diluted or undiluted form, depending on the severity of the skin affliction. The powerful anti-inflammatory properties of the oil can also soothe redness, itchiness, and swollen areas of the skin.
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.
Research on CBD and anxiety has generally looked at cannabis as a whole product, 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.

All this talk about THC lands us nicely in the whole “Full Spectrum vs. Pure Isolate” debate. Once you begin shopping for CBD products, you’ll notice a lot of jargon that gets thrown around without much explanation. Now that we’ve introduced THC into the conversation, we can talk about the difference between, and relative benefits of, Full Spectrum CBD and CBD Isolate (and the lesser-known contender: Broad Spectrum).


There are more than 80 cannabinoids found in cannabis plants, with THC being the primary one, followed by CBD. However, in the hemp plant, which is a different strain of the species Cannabis sativa, CBD is the main active ingredient, and THC is barely present, making its use and legality more widespread. The reason that CBD is such an effective form of support for human health is due to the body’s endogenous cannabinoid system. This regulatory structure of the body has millions of cannabinoid receptors in the brain and nervous system, which react not only to plant-derived cannabinoids (such as hemp and marijuana) but also to natural cannabinoids produced within our body. When hemp oil is used and processed by the body, it is effectively boosting the function of the endocannabinoid system, helping our body regulate itself in many different ways.
You are likely very familiar with the dangers that prescription painkillers (and other pharmaceuticals) present. In fact, it’s estimated that the majority of CBD oil users attempt to switch to the all-natural therapy for the precise reason of kicking prescription med habits, which all too often cause an overwhelming array of irritability, sleep disruption, digestive complications, and even thoughts of suicide.
Read the label to find out the total milligrams of CBD in the entire bottle/product and how many milligrams are in one standard dose. CBD products vary in potency, with some containing more total CBD than others. Most products will have on the label exactly how much CBD is in one dropper or drop, so you’ll be able to tell exactly how much is in there.

When administered alone, CBD is an effective anticonvulsant in maximal electrical shock (MES), magnesium-free, 4-aminopyridine, and audiogenic models (7, 8). Co-administration with AEDs leads to various effects; anticonvulsant effects of CBD are enhanced with phenytoin or phenobarbital but decreased with chlordiazepoxide, clonazepam, trimethadione, and ethosuximide. In a recent study using an acute pilocarpine model, although CBD administration reduced the number of animals displaying seizure activity, CBD did not appear to have any significant effect on the number of seizures per animal (7).
