The gel formula creates a protective barrier over the sore to encourage the natural healing process. Canker sores and cold sores are often confused with each other, but they are not the same. Cold sores are caused by a virus; canker sores are not. Cold sores typically appear on the lips, outside the mouth. Canker sores always appear inside the mouth. Canker sores are small whitish-gray blisters that appear on the tongue, inside the cheeks, or on the soft palate. They are small but very painful! There is no single cause, but cheek biting, stress, braces, dentures, and other factors may trigger them.The herbal and nutrient ingredients include: Herbal pain relievers – Menthol, mint, and castor oils Immune supporting nutrients – Aloe, calendula, myrrh, goldenseal, propolis, and echinacea Oral health nutrients – B12, lysine, and zinc The herbal blend has a light minty taste without any flavorings or additives. Millions of people deal with recurring canker sores. Be kind to yourself and choose a natural solution that works!Active Ingredient: Menthol 5%
