GNC Herbal Plus Ashwagandha Extract promotes general well-being and is a vegetarian standardized extract. Whole herbs are usually dried, chopped, or ground into powder, and may be processed with water or alcohol for encapsulation. Standardized herbal extracts are made by dissolving herbs in a solvent like water, alcohol, or liquid carbon dioxide, resulting in a chemical extract. The goal of standardization is to provide uniformity of a specific constituent that may be biologically active.
