Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43 percent had more CBD than indicated, while 26 percent had less, and some had unexpected THC.“There’s a 75 percent chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.

It all starts with the connection between the endocannabinoid system and intestinal function/motility. Recent studies have found that the transmitters regulated by the endocannabinoid system are located throughout the human body. Some of these transmitters are responsible for gut function; when imbalanced, negative effects are likely to occur. (41)

The effects of CBD on receptors in the immune system may help reduce overall inflammation in the body. In turn, CBD oil may offer benefits for acne management. A human study published in the Journal of Clinical Investigationfound that the oil prevented activity in sebaceous glands. These glands are responsible for producing sebum, a natural oily substance that hydrates the skin. Too much sebum, however, can lead to acne.
There are numerous wonderful resources on (but not restricted to) the web regarding CBD, the major phytocannabinoid which has added a whole extra dimension to cannabis-related studies, medication, and dietary supplementation. On the other hand, as is often the case with a novel matter, there is also a great deal of misinformation regarding its benefits.
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.
Low Blood Pressure and Lightheadedness – an effect of CBD that may seem somewhat counterintuitive, an almost immediate (though small) decrease in blood pressure has been reported at the exposure to high doses, causing the associated lightheadedness, albeit not for long periods. Nevertheless, it could be significant for individuals taking blood pressure medication.

CBD oil contains CBD (and often other active compounds) in a carrier oil. There are a number of forms of CBD oil, including softgel capsules, tinctures, and under-the-tongue sprays. Some forms of CBD oil can also be applied directly to the skin, in the form of products like creams and salves. The concentration of CBD varies from product to product.
According to one board-certified dermatologist who specializes in cannabinoids in skin care and treatment, Jeanette Jacknin, as recently published in the Strategist, the way CBD interacts with the endocannabinoid system, helps the skin look more “radiant and youthful” slowing down the signs of aging. Furthermore, its anti-inflammatory actions and interactions with the body can help decrease the effects of acne, eczema and psoriasis. (15)
THC does typically come with a long list of health benefits, but the clinical use of this cannabis compound is often limited by its unwanted psychoactive side effects in people. For this reason, interest in non-intoxicating phytocannabinoids, such as CBD, has substantially increased in recent years. In fact, CBD is being used in conjunction with THC for more favorable effects.
