The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors (whimsically named CB1 and CB2) in the endocannabinoid system, and each affects your body in different ways. CBD and its infamous cousin THC are the 2 most well-known cannabinoids.
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.
Moreover, Murray Mittleman, an associate professor of medicine at Harvard Medical School, explained to Time Magazine in 2013 that weed users had lower fasting insulin levels and were less resistant to insulin produced by the body. He was referring to research from the National Health and Nutrition Examination Survey, which analyzed 4,600 men and women over a five year period from 2005 to 2010. 48% of them used marijuana at least once in their lives, and 12% were current weed users.
CBD oil has been scientifically proven to reduce stress. It combats stress both psychologically and physically. Psychologically, it levels out your brains cortisol levels. Cortisol is the stress hormone, and high levels are associated with chronic depression, anxiety, and low immune function. Whenever you get stressed out, your body produces excessive amounts of the chemical.
