Plural of enema; medical procedures where liquid is introduced into the colon to cleanse the bowels or deliver medicine.
From Greek 'enema' meaning 'an injection,' from 'enemein' (to inject), from 'en-' (in) plus 'hienai' (to send). The plural keeps the Greek '-s' ending.
Enemas have been used for thousands of years—ancient Egyptians were obsessed with them, and the procedure's popularity in medicine shows how humans have always been convinced that cleaning the gut cures everything.
