The natural occurring compounds found in plants are called phytochemicals and have been extracted using ethyl alcohol for use as medicinal remedies for a long, long time. The ingredients in plants are highly soluble in alcohol and easily extracted, however cannabinoids are only significantly soluble in more concentrated ethanol solutions greater than 75% (150 proof) but ideally 190 proof should be used. With the 190 proof ethanol the cannabinoids, terpenoids, flavonoids and other essential oils will be easily extracted.
