Please note: David Winston has reformulated Sinus Support Compound. The herbs in a formula may change occasionally for various reasons. An herb may no longer being available due to sustainability or quality concerns as was the case in Eyebright. We could no longer find Eyebright that met our stringent quality standards. It has been replaced with Amla, an herb rich in polyphenols which gives it its activity, and Yerba Santa, an herb historically used for respiratory system support.
