So, many of CBD's popularized benefits aren't well-proven. But are there any harms in trying CBD-containing products? In a word, yes. While any reported side effects from CBD alone are minor (think dry mouth and dizziness), they can be serious if the CBD products interact with other medications, experts say. Since CBD is metabolized by the same enzyme in the liver that metabolizes many conventional medicines and supplements, the chemical can cause the levels of other drugs in the system to rise; in some cases – like for those taking a drug to prevent their bodies from rejecting a donor organ – to a deadly level, Tishler says.
From anecdotal evidence in humans and from animal studies, CBD appears to affect the way we experience pain, inflammation, and anxiety. “Scientists have identified a number of receptors in the nervous system where CBD acts,” says Orrin Devinsky, MD, professor of neurology, neurosurgery, and psychiatry at NYU Langone. “It’s established that CBD has anti-inflammatory properties and can increase activity at some serotonin [the feel-good neurotransmitter] receptors.”
CBD hemp oil has a number of uses and comes in many forms including capsules, tinctures, sublingual supplements, liquid oil, oil as a paste, sprays, salves, creams and in edible forms, such as candies or sweets. You can also inhale CBD oil from vapor-releasing pens, similar to the technology for e-cigarettes. This variety also provides a lot of controlled flexibility in terms of concentration, making CBD hemp oil useful and desirable for people of all ages, economic means, and personal needs.
You need a series of chambers for CO2 extraction. Their role is to control pressure and temperature. The pressure and temperature in the chambers force the CO2 cannabinoid solution to react with one another and then separate. As the cannabinoids separate, the chambers collect them separately. The extractor can then choose which cannabinoids to put into their product or products.
Anyway, the research showed that in mice, CBD was much more effective when used along with other compounds of the cannabis plant, than when it was used by itself. While they haven’t yet figured out why exactly this is the case, it’s now generally accepted that full-spectrum CBD oil is more effective at treating the majority of medical conditions, than is CBD isolate.
Not much, as far as humans are concerned—at least not yet. The vast majority of studies have been on animals, as of yet, and there are few high-quality studies on humans. Even the oil’s effect on pain—something that CBD oil is popularly used for—isn’t proven. “The studies available are small or not well designed,” says Dr. Devinsky. “There’s a lot of religion out there, but not a lot of data.”
We also grow our hemp in close rows, limiting the ability of weeds to establish themselves among our fields. Since we sow our hemp seeds close together, the shade from the fast growing hemp plants inhibit the growth of common weeds, negating the need to use herbicides that could cause contamination. Like with pesticides, we avoid using herbicides because they can affect local biological communities or be absorbed by our hemp plants and transferred residually to our customers.
"If it proved effective for anxiety, depression and panic disorder, it may have other effects as well that could be useful and beneficial [but] this is a really early stage," says David Shurtleff, the acting director of the National Center for Complementary and Integrative Health. His organization's stance: "Take it one step at a time and do the work and really state where we are right now with the research," he says.
“What is CBD oil” may be your first question, but the real question we have to answer is, “What does CBD oil do?” CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.
