IS BUTANE THE ONLY SOLVENT NEEDED FOR A COMPLETE EXTRACTION?
Sometimes, to perform a complete extraction of an herb or plant, you will need a small amount of one or more other solvents such as alcohol or acetone. This is to be added to the butane before you begin the extraction process. This is the remarkable feature of using butane. Because you can add these other solvents in a variety of combinations, the possible plants you can extract from is virtually unrestricted.
