If I were to buy/build a large still, that was air tight, and could hold a vacuum, and filled the reservoir with vegetable glycerin (which has a boiling point higher than the majority or desired organic compounds) and I made the atmospheric pressure inside less than normal atmospheric pressure, could I distill chemicals out of organic matter without altering them? Such as distilling willow bark to get an aspirin containing solution, or distill mint leaves without changing the chemical composition of the medicinal compounds in the plant/organic matter?
This could be a cool project. It would enable us to explore further into natural medicine. But would this procedure work?
