Dong-A Pharmaceutical Gargrin Zero

That thing everyone has probably thought about at least once while gargling: a mouthwash that isn't spicy! Fortunately, there was an alcohol-free Gargrin product available. It isn't completely non-spicy, but it stings slightly if you hold it in your mouth for a while. Still, while it is difficult to hold other mouthwashes for more than 30 seconds, I was able to with Gargrin Zero. I used to think that the spicier it was, the better the effect, but it turns out that isn't necessarily the case.
