Povidone is a type of iodine used in surgical procedures as an antiseptic or disinfectant. As a douche, it has been recommended for decades by doctors and pharmacists for cleansing & deodorizing the vaginal area & for the relief of minor irritation & itching. Our convenient disposable twin pack includes povidone "unettes." The consumer mixes the "unettes" with the enclosed bottles of purified water, then douches & disposes.
