Even for a sore throat You can use it as a mouthwash. When my gums are swollen and sore, I hold Tantum mouthwash in my mouth, swish it around, and then spit it out. It is best not to rinse with water after gargling. If the undiluted solution is too strong, you can dilute it with water before gargling. It is convenient to use as there is a measuring cup on the lid.
