Just a small amount of this liquid works for up to 8 days against thrush and aids in the prevention of thrush. Forms an antiseptic barrier between healthy tissue and thrush. Its unique purple color tells you where it's doing the job, with a fresh coat needed only where the color has faded. Effective, yet milder to sensitive tissues than some other commercial preparations that contain bleaches, copper sulfate or turpentine. May also be used before applying sole pads and silicon to toughen thin-soled feet and reduce bacteria counts. Use in a well-ventilated area. 2 oz.
