ALCOHOL VS. CO₂ EXTRACTION
Carbon dioxide is a liquid gas and only extracts the non-polar chemicals of a plant. Alcohol is a solvent that is made due to plant fermentation and is a by product of plants themselves. Alcohol is also the only solvent that maintains the original chemical ratios contained in the plant. This is due to alcohol extracting both water soluble & oil soluble components. The use of carbon dioxide results in a very limited extraction of the plant. Since the extracts of carbon dioxide are non-polar, carbon dioxide extracts are not water-soluble. This plays a vital role in bio-availability. Since our bodies are 70% water, oils must be digested by different acids & enzymes to become active. During this digestion process, the active ingredients of the oils are degraded.
