Are alcohol-free herbal extracts as concentrated as the alcohol extracts?
Not for all companies! In fact, only the most reputable companies capable of extracting first with USP grain alcohol then distilling off the alcohol and testing the finished product with HPLC instruments can claim that the alcohol free products are as concentrated as the alcohol extracts. Many companies extract the herbs for their alcohol free products with vegetable glycerin. Unfortunately, vegetable glycerin is not a good solvent and cannot effectively extract the same constituents the grain alcohol can extract.
