Alcohol extraction is far superior to any other method of extraction as it extracts the most amount of chemicals compared to any other solvent. Since alcohol is both non-polar and polar, it can dissolve a much wider range of molecules that includes almost all of the plants medicinal oils, polysaccharides, carboxylic acids and other beneficial chemicals. In other words, alcohol dissolves both water and oil soluble chemicals found in the plant where-as carbon dioxide extraction (a.k.a CO2 extraction) can only dissolve the oil soluble chemicals.  In terms of keeping the plant whole and together while maintaining the original chemical ratios contained in the plant, alcohol is the only solvent for the job. Using the method of carbon dioxide extraction (CO2...
