Invented in Tipperary almost a century ago, Euthymol is, at first brush, the exact color and flavor of Pepto Bismol. But while Pepto's distinct tang is attributed to wintergreen, the secret of Euthymol's flavor lies in its name: thymol, a natural chemical compound that gives thyme its flavor and is valued as an antiseptic. Even though I know their formulas are different, I still can't separate the two products in my mind. Some won't want to think about nausea, heartburn, and indigestion, while they're brushing their teeth. I get that. For me, it's more of a fresh look at a recognizable yet difficult-to-place flavor long associated with gastrointestinal discomfort. Use Euthymol long enough, and your perspective on bright pink pharmaceutical substances will start to change.
