Alkaline Saline Mouthrinse Solution

What is an alkaline saline mouthrinse?

An alkaline saline mouthrinse is a rinse you can make at home to help manage mouth and throat sores. Some treatments, such as chemotherapy or radiation, may affect the cells in the mouth and digestive tract and cause mucositis. This may cause redness, swelling, tenderness, and sores on the lining of the mouth, tongue, and lips.
