CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
CBD affects the endocannabinoid system, which has cannabinoid receptors throughout the human body. That’s one of the major reasons why CBD’s therapeutic properties include pain relief. The cannabinoid receptors are connected to the human nervous system. CBD affects some of them (not CB1 and CB2 which are activated by THC) and a neural connection is triggered in the brain.
Dr. Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.
Current studies, including one carried out by the UC San Diego School of Medicine, are looking into how the endocannabinoid system may be linked to reducing symptoms associated with autism. This is due to its role in social reward responsivity, neural development and circadian rhythm and anxiety regulation – all of which are often affected by autism. (52)
Another field in which CBD is creating a buzz is in the area of mood disorders like anxiety and depression. Both conditions have been treated with a variety of medications, courtesy of Big Pharma, that have had varying levels of success. Again, the long list of side effects can be off-putting to someone who just wants to get through the day without the sweaty tension of anxiety or the gray haze of depression.
Your body is checking if you need water, food, or rest, if your hormone levels are right, and if everything in your cells and bloodstream are stable. Its goals is to keep everything at a normal range. For example, if it’s hot outside, it helps you cool down through sweating. If you need fuel, it makes your stomach growl to urge you to eat. It accomplishes these things with the help of two cannabinoid receptors, CB1 and CB2.
The science behind CBD is in the relatively early stages. As a cannabinoid, we know that CBD interacts with receptors in your endocannabinoid system. The endocannabinoid system is integrated throughout your body — and this widespread, whole-body interaction creates a broad range of effects. Hence, the long list of possible benefits. We may still be in the early stages of discovery, but there’s plenty of scientific studies and anecdotal evidence that CBD provides relief for an array of ailments. Here’s a non-exhaustive list of some potential benefits of CBD oil:
A study published by David Cheng, Postdoctoral Scientist, Neuroscience Research, University of New South Wales, NSW, Australia, says that CBD has a potential as a preventive measure against symptoms of Alzheimer’s. This presents yet another exciting development for medical researchers, given the persistent challenges to finding effective solutions for this condition.
Prescription opioids, such as codeine, hydrocodone, oxycodone, oxymorphone, fentanyl, and morphine are medications that are naturally found in the opium poppy plant. Besides relieving pain, they can make you relaxed and high. The problem is that opioids are highly addictive, and overuse and death are incredibly common as a result of opioids. This is true for prescription opioids, and people taking prescription opioids may become addicted and suffer from consequences. Yet doctors are still commonly prescribing opiods even in less serious cases (17).
