Tons of different medical organizations have named themselves after Hygeia—everything from laboratories to insurance companies to disease awareness groups. (Still, Hygeia kind of misses the good old days when she was worshiped.)
10 Hygiea is the name of a big old asteroid that does its thing between Mars and Jupiter.
"Hygeia's Bowl" is a symbol used for pharmacies. You probably recognize it: it's a snake wrapped around a bowl. (Not super inviting, if you ask us.)
Back in the day, Hygeia and her dad, Asclepius, had some big deal temples in the Argos and Epidaurus. (Source.)
