What is CO2 extraction?

CO2 extraction is an extraction process that uses pressurized carbon dioxide (CO2) to extract phytochemicals (such as CBD, CBG, or terpenes, flavonoids, etc.) from a plant. CO2 at certain temperatures and pressures acts like a solvent, without the dangers of actually being one. It is the most expensive extraction method and is widely considered the most effective and safest plant extraction method.
