Medical and veterinary applications of light to therapeutic compounds include a solution retainer adapted to retain a therapeutic solution against a tissue of a user； a fiber optic cable； a light source that connects with the fiber optic cable and provides a light of a predetermined wavelength to the fiber optic cable； and a light termination on the fiber optic cable that exposes the light to the therapeutic solution. A formulation includes an oxidizer； the therapeutic solution having an initial therapeutic effectiveness； and a light of a predetermined frequency that that undergoes a synergistic reaction with the oxidizer, thereby enhancing the initial therapeutic effectiveness of the solution.
