Alcohol extraction, also referred to as ethanol extraction, is a solvent-based method used to extract the active ingredients from the cannabis plant, into a cannabis extract. It’s one of the safest and, along with CO2, one of the most commonly used extraction methods, since there’s no risk of leaving toxic residuals in the final product.
The plant’s material is soaked in alcohol to separate the cannabinoids and terpenes, then the resulting liquid is filtered and finally heated to evaporate the remaining alcohol.
Alcohol extraction can also be done by using isopropyl alcohol instead of ethanol.
