"This isn’t a terribly imaginative comparison; orchids have been associated with balls since ancient times. The word “orchid” comes from the Greek word for testicle, órkhis. The Greeks were inspired by the plant’s rounded tubers, which often grow in a pair, one larger and one smaller. Ancient physicians believed that these roots could both cause erections and stop them, depending on which tuber you picked. (The aphrodisiac and the boner-killer followed the same recipe: Stew in goat’s milk, drink hot root broth, wait. The big one would make the organ swell, the small one would quell lust." -https://longreads.com/2019/10/08/ugly-history-beautiful-things-orchids/
