First, ethanol is a polar solvent. This means that it will readily mix with water and dissolve water-soluble molecules. This creates a great challenge for companies using the ethanol extraction method because chlorophyll is one of the compounds that will easily co-extract. Chlorophyll in the concentrate will result in a dark green coloring and an unpleasant bitter, grassy flavor.
Blood pressure. Scientists say that CBD can also aid the lowering of blood pressure in humans, mainly by reducing the body's systolic pressure in the arteries as the human heart pumps blood. By taking a moderate dosage of CBD oil, some health experts say, an individual can improve blood flow, lower the heart rate and reduce the anxiety the stress often found in patients with high blood pressure.
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”
"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.
CBD is one of over 110 active cannabinoids inside marijuana plants and is most predominant inside the resin glands (trichomes) of the female cannabis plant. Your body contains cell receptors known as cannabinoid receptors. Cannabinoids, found in cannabis, are agonists that bind to these receptors. Cannabinoid receptors can be found all over the body including, but not limited to, the:
The same terms could be applied to what's actually in CBD products. While some do contain CBD, others (often marketed as "CBD-rich hemp oil") may have barely any, Asquith says. And depending on state laws, they can include varying levels of THC too – a combination shown to have some benefits, but also drawbacks, of course, if you're not looking for a high. "People will play all these games with the numbers because the consumers aren't really educated in this space yet and it's easy to get taken advantage of," he says. "It's the milligrams of the actual CBD molecule that matter."
In the United States marijuana is still listed under Schedule I of the Controlled Substances Act. However, the federal Food and Drug Administration (FDA) has authorized clinical trials on a CBD-based drug that treats childhood-onset epilepsy. CBD oil also shows promise in treating intestinal conditions as well as anxiety, post-workout aches, inflammation, and some types of cancers. Additional conditions are neurological inflammation, oxidative injury, and schizophrenia.
So which is better? Hemp derived CBD or Medical marijuana derived CBD? I believe, given the information I have found, that the reasonable and definitive question we should ask is: What are the pros and cons of both options and, most of all, what will be best for me and fit my lifestyle. In addition, legality within the state and country you live must be taken into consideration.
There is a strong sedative quality to CBD hemp oil, making it a popular remedy for people with insomnia, sleeplessness, interrupted sleep, post-traumatic stress disorder, restless leg disorder, and other night-time issues. Dr. Scott Shannon, Assistant Clinical Professor of Psychiatry at the University of Colorado School of Medicine, USA, published a report in the Permanete Journal, in which he recommended either inhaling a small amount of CBD oil, applying it to one’s chest, or even putting a few drops on one’s pillow to help get a good night’s sleep.
