Where does “dill” come from?

I appreciate the detailed instructions, but I notice there's a mismatch in your request: you've asked me to write an origin summary for "dill" (the herb), but the etymological chain you've provided traces "dull" (the adjective meaning not sharp or boring). Could you clarify which word you'd like me to write about? If it's "dill," I'll need the correct etymological chain. If it's "dull," I can write the summary using the chain you provided.

dill (English): Anethum graveolens (the type species of the genus Anethum), a herb, the seeds of which are moderately warming, pungent, and aromatic, formerly used as a soothing medicine for children; also known as dillseed
