Meconic acid, also known as acidum meconicum and poppy acid, is a chemical substance found in certain plants of the Papaveraceae family (poppy) such as Papaver somniferum (opium poppy) and Papaver bracteatum.
Oriental poppies are closely related to the Great scarlet poppy Papaver bracteatum, which can be grown for the commercial extraction of thebaine, a main source for the legal synthesis of opiates.
