Alcohol extracts have been used for thousands of years to separate desirable medicinal or flavoring elements from plant materials. Ethanol is a food safe and effective solvent for these compounds, which include oils, phenols, terpenes, aldehydes, and other components that are a natural and essential part of every plant. Alcohol is able to dissolve all of these components to create a ‘tincture’ or solution.
Alcohol will dissolve both water soluble hydrophilic compounds as well as oily, hydrophobic compounds. For many extracts and concentrates, this ability to dissolve many kinds of essences from the plant material is desired and important. Many medicinals and dietary supplements include water soluble compounds. For other purposes, the oily components are most important and the water soluble components are removed to provide a more pleasant or useful end product. Alcohol can be used for these processes as well with careful treatment and preparation of the tinctures and finished concentrates to separate specific essences of interest.
Alcohol is a consistent, easily available, economical and safe solvent to create an endless selection of essential concentrates.
Residual alcohol in the final concentrate products are generally completely safe for ingestion as well, which is an important difference from the use of butane or other hydrocarbons. And alcohol is easily removed from the final concentrate, if desired.
Grain alcohol is not explosive at low temperature. The Source operates at normal body temperatures, and operates in a vacuum rather than at high pressures. The Source is inherently safer than CO2 or butane/hydrocarbon extraction.
