gentian (n.) Look up gentian at
type of herb, late 14c., genciane, from Old French genciane (13c.) and directly from Latin gentiana, said by Pliny to be named for Gentius, king of ancient Illyria who discovered its properties. This likely is a folk-etymology, but the word may be Illyrian nonetheless, because the suffix -an frequently occurs in Illyrian words.
