your brain's overcautious bouncer, throwing out anything it suspects might be poison.
means The queasy, unsettled feeling in your stomach that signals you might be about to vomit.
from From Greek nausia, meaning seasickness — built on naus, "ship" (the same root that sails into "nautical" and "navy"). The Greeks knew the lurching deck of a boat as the original stomach-turner, so the word literally means "boat-sickness." It rolled through Latin as nausea before docking in English.
