Is Gentian Violet toxic?!
Question: Yes but not anywhere near a Merthiolate.
Answers: Yes but not anywhere near a Merthiolate.
If you're only using normal amounts, no. It's used in tampons, cures for poison ivy, stains, and determining what antibiotic to use to treat people.
When it's used to treat thrush in large amounts, though, it is shown to be linked with mouth cancer.
