Similasan®'s unique Ear Wax Relief™ not only removes wax and cleans the ear, but stimulates the body's natural ability to reduce chronic ear wax congestion (wax build-up). This original Swiss formula is glycerin based and will not cause dry skin or itching of the ear canal. Homeopathic medications use natural, active ingredients and work effectively with no known side effects and no known drug interactions. Peroxide free.
