Part 3 of be Natural CBD Extraction Methods with Dr. Baar / Alcohol Extraction Method
Ethanol or ethyl alcohol extraction is another method that can be used but has lost its popularity in favor of a more efficient and effective method.
Ethanol is considered safe by the FDA, and it is in a range of products, from paint to personal care items that you probably have in your house right now. This method works similarly to other solvent methods, but better for a few reasons.
Most notably, ethanol is safe for consumption and doesn’t create the same residues or contaminants as other solvents might, so you get a more pure CBD. Ethanol also is a polar solvent, which allows it to pull more water-soluble molecules. This can also pose problems though because it can pull more chlorophyll from the plant matter. In this method, plant matter is decarboxylated and then packed tightly into a container.
Ethanol is then dripped through that container, stripping the cannabinoids with it as it drips through into the collection reservoir. This can be done in hot or cold conditions. Another way to use ethanol is to soak the plant matter in the liquid until the CBD, and other cannabinoids have been drawn out of the hemp, and then ethanol is boiled away. But, due to the way the ethanol pulls out plant waxes and other components, as well as its high boiling temperature, there is a lengthy purification process, and certain CBD products can’t be made this way.
