Abstract

Raw plant material is mixed with ethanol under pressure to extract essential elements. The resulting crude oil and ethanol with the dissolved essential elements is separated from the raw plant material and filtered to remove particulates, waxes, lipids, fats and dissolved impurities. The ethanol is then evaporated from the resulting mixture of crude oil and ethanol, and the remaining crude oil then undergoes decarboxylation and distillation to obtain the essential elements. The ethanol may be chilled before adding it to the raw plant material.
