Acting against or opposing tartaric acid or its effects.
From anti- (against) + tartaric, from French tartare (tartar, cream of tartar), from Medieval Latin tartarum, possibly from Arabic or Persian origin. This rare term relates to the chemistry of acids and their neutralization.
Tartaric acid is naturally abundant in grapes and tastes sour—antitartaric substances would theoretically neutralize it, though the term is mostly obsolete since we just call that 'alkali' or 'base' now.
