Opposing or counteracting acrid qualities; serving to reduce sharpness, bitterness, or harshness of taste or sensation.
From anti- (meaning 'against') plus acrid (from Latin acer, meaning 'sharp' or 'sour'), creating an adjective that means 'against acridness.'
This nearly obsolete medical term was used historically to describe substances that would soothe harsh, burning sensations in the mouth or throat—a precursor to our modern understanding of how protective compounds work!
