Solvent Extraction

Solvent Extraction:  Solvent extraction consists of placing raw material/s in a chemical solvent (often times hexane) and then vacuum-separating the now removing the materials from the solvent. This is one of the most common method for extracting herbal concentrates and fragrances from natural products.

One of the issues with this method is that the solvent is not completely removed and can be a residual toxin.
