CBD offers many of the health benefits of medical marijuana without the high, making it more versatile and less controversial to both users and the community.
In addition, CBD oil can be extracted and manufactured through “supercritical CO2 extraction.” This process involves using carbon dioxide under high pressure in an extremely cold environment. Supercritical CO2 extraction requires expensive equipment, more complex refinement process and production expertise, but it ensures that CBD oil maintains its purity all through the process.
The aforementioned entourage effect is the main reason behind the efficacy of whole plant extracts. There are over 100 ‘identified’ compounds in the cannabis plant. While most of these compounds have their own therapeutic benefit, they combine synergistically to provide a far better performance than any single compound, including CBD. Here are a couple of examples of conditions that benefit from the entourage effect:
