What is a notable characteristic of Gentian violet?

Gentian violet is notably characterized by its ability to stain the skin and clothing a bright purple color. This property arises from its strong dye characteristics, which is why it has been used historically in various applications, including as a topical antiseptic. The vivid color can often be a visual indicator of where the solution has been applied.

This staining ability is sometimes seen as a disadvantage due to the difficulty in removing the dye from fabric and skin, but it also allows for easy visualization of treatment areas. Gentian violet’s staining effect is also part of its historical use in treating certain fungal infections and as an antimicrobial agent.

The other options do not accurately describe gentian violet’s primary or notable properties. For instance, it is not odorless, nor is it a topical anesthetic. Additionally, although gentian violet can have antibacterial properties, its primary and most recognizable characteristic is its bright purple staining capability.
