Thrush Buster – Single application thrush treatment lasts up to 8 days, even in the wettest, muddiest terrain. Relieves the agonizing, crippling effects of thrush while reducing the chance of reinfection. Creates an antiseptic barrier between healthy tissue and thrush. Purple color tells you where it’s working, with a fresh coat needed only where it has faded. May be used before applying sole pads and silicon to toughen thin-soled feet and reduce bacteria counts.
