In order to produce CBD rich cannabis oil, you first need to start with hemp high in CBD. There are numerous methods of extraction which are utilized to the countless CBD companies today and each has their own pros and cons on a manufacturing level, however, when executed properly, can produce CBD rich oil for various types of products. The two most popular methods are CO2 Extraction and Ethanol Extraction.
- CO2 extraction. The supercritical CO2 method uses carbon dioxide under high pressure and extremely low temperatures to isolate, preserve, and maintain the purity of the medicinal oil. This process requires expensive equipment and a steep operational learning curve. But, when done well the end product is safe, potent, and free of chlorophyll.
- Ethanol. High-grade grain alcohol can be used to create high-quality cannabis oil. This method requires you to soak the plant material in ethanol, leaving behind a cannabinoid rich solution which can then be heated to remove any remaining alcohol.
These extraction methods can be used to produce either full spectrum oils or CBD isolate which are both considered highly effective when properly obtained.
