A yellow or orange antiseptic dye compound used historically as a disinfectant and in medical treatments.
From Greek eu- (good, well) and Latin flavus (yellow), literally 'good yellow' or 'fine yellow,' describing its distinctive color and beneficial antiseptic properties.
Euflavine was the bright yellow-orange dye that doctors used to paint on wounds before modern antibiotics—it actually worked as an antiseptic, and it stained everything yellow for weeks, which is probably why hospital gowns are still that particular shade.
