Ethanol Extraction
How Ethanol Extraction Works. Ethanol extraction uses ethanol as a solvent that is combined with the hemp biomass. In doing this, the ethanol pulls desired hemp compounds (CBD, and other cannabinoids depending on the biomass used) from the plant material along with other plant compounds such as fats, waxes, terpenes and other materials. The extracted complex of
