the.com/revulsion

means A strong feeling of disgust or repugnance, sharp enough that your whole body seems to recoil from it.

from From Latin revulsio, 'a pulling away,' built from re- ('back') plus vellere ('to pluck or tear'). It originally had a literal, almost medical sense of wrenching something away or diverting it forcibly — old physicians spoke of 'revulsion' when drawing blood or disease from one part of the body to another. Over time the pulling-away became internal and emotional: instead of yanking something out of the body, the word came to describe the body yanking itself away from something — the visceral recoil we now call disgust.
