Use listerine mouthwash, and your tongue will feel very spicy. Why? Is it harmful?

The advantage of listerine is that it kills 99.9% of bacteria, but the disadvantage is that it will destroy the oral environment and kill 0.0 1% of probiotics. It is recommended that people in need use it, and don't use it often unless necessary. After gargling, you should rinse with clear water. Listerine is 22% ethanol, so it's very spicy, and you smell like alcohol. It is unlikely to be used on your tongue and mouth.
