NCIt definition : A white crystalline dicarboxylic acid found in many plants, particularly tamarinds
and grapes. Tartaric acid is used to generate carbon dioxide through interaction with
sodium bicarbonate following oral administration. Carbon dioxide extends the stomach
and provides a negative contrast medium during double contrast radiography. In high
doses, this agent acts as a muscle toxin by inhibiting the production of malic acid,
which could cause paralysis and maybe death.;
