Do you have mouth or throat ulcers? Treat them with this!
Now don't waste your time - like I did - taking extra strength aspirin and gargling with salt water. Gargling with this stuff is like swallowing a nuclear shitstorm. You basically want to wipe out an excess bacterial shit in your mouth. Take a gulpful of this - Listerine antibacterial - and feel it burn. Now you KNOW what it's doing to the germs in your mouth.
In case you don't know already, those sores in your mouth are a sign of a depleted immune system, and further, you're probably eating too much fast food and drinking too many sweet sodas [which kill the immune system]. Lay off of greasy food - concentrate on fish, bread, fruit like apples, and lots of water.
One further word of advice - brush teeth and gums thoroughly before using this mouthwash to maximise benefits. Now get well.
