Interesting topic! I am a writer and the Thesaurus, whether book form or online, is my best friend. How about Apothecary - It just came to me as a word to look up:
"Main Entry: apothecary [uh-poth-uh-ker-ee]
Part of Speech: noun
Synonyms: dispenser, druggist, gallipot
Notes: in the US, one says druggist , but chemist in the UK; pharmacist is a formal term in both countries and apothecary is the old-fashioned term."
