Lab techs use state of the art equipment to create phase changes in carbon dioxide by utilizing temperature and pressure. The carbon dioxide is cooled and compressed to upwards of 10,000 psi – by comparison your car tire is pressurized to about 300 psi. When compressed to these extremes, CO2 becomes ‘supercritical’, which simply means that it converts to liquid when placed under extreme pressure.
Full spectrum (or “whole plant”) products contain CBD as well as terpenes and other cannabinoids such as CBG, CBN and trace amounts of THC. Usually these will be in ratios that were naturally-occurring and extracted from the plant and specific strain. Terpenes and cannabinoids are occasionally added back into products as an isolated form to raise the potency of the product.
Along with its better-known counterpart, THC (delta-9-tetrahydrocannabinol, the chemical that produces the marijuana high), CBD is one of more than 400 compounds found in the oils of cannabis plant species, which include marijuana and hemp. Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, Ph.D., director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”
Like we mentioned a moment ago, it used to be the belief that “pure CBD,” or CBD isolate, packed the most potent punch in terms of cannabis therapy. And that would make sense too, right? If we know that CBD is primarily the active compound in the plant that provides the medical relief and therapy, then wouldn’t it make sense to make a 100% pure powder out of it?
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.
Cannabinol results from the degradation of THC. There is little of it in the fresh plant, but decarboxylation often raises the amount of CBN in the plant as an effect. CBN is only mildly psychoactive and has a higher affinity for the CB2 receptor than the CB1 receptor, linking CBN to the body’s immune system. In hemp oil, CBN is present in levels of 0.2% or lower.
Another major reason why CBD oil has been positively received in some parts of the medical community is its apparent effect on cancer and tumor growth.A study done by the researchers of the Institute of Toxicology and Pharmacology, University of Rostock, Germany recommends the use of CBD oil (even direct injection into tumors) to eliminate or reduce the size of the tumors. The antioxidants in CBD hemp oil also provide anti-mutagenic properties and lower users’ risk of cancer.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
CBD oil took the world by storm a few years ago when Dr. Sanjay Gupta investigated the cannabinoid’s ability to treat children with epilepsy. Initially, CBD oil was viewed as a medicine for the critically ill, but its appeal to the general public is surging. With few regulations, the CBD oil market is congested with questionable products. As a consumer of CBD oils, it is essential for you to know how they are made.
Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD.
