Both the generic name Lamium and the specific epithet galeobdolon were used by Pliny the Elder in the first century AD.[43] The name galeobdolon has several possible origins.[44] It may come from the Latin words galeo meaning “to cover with a helmet” and dolon meaning “a fly’s sting”, or it may come from the Greek words γαλέη (galéē) “weasel; marten; polecat”, and βδόλος (bdólos) “foetid smell”, an allusion to the smell of the leaves. The latter interpretation is likely the source of the old common name ‘yellow weasel-snout’.[45]
The Latin name is fun though.
