oxalic acid

 [ok-sal´ik]
a poisonous dicarboxylic acid found in various fruits and vegetables, and formed in the metabolism of ascorbic acid and ethylene glycol. While it is not usually a problem with normal diets, it is seen in high concentrations in certain ornamental plants (such as Diffenbachia), as well as in some bleaches and antirust products. Persons or animals that chew on the plants or otherwise consume the chemical can be poisoned. Oxalic acid is highly toxic and if ingested vomiting should not be induced. If the person is at home, a poison control center and emergency services should be contacted immediately. The acid can be neutralized by administration of calcium by either the oral or the intravenous route. High urinary oxalate concentrations may cause deposition of kidney stones and other urinary calculi.

ox·al·ic ac·id

(ok-sal'ik as'id),
An acid found in many plants and vegetables, particularly in buckwheat (family Polygoniaceae) and Oxalis (family Oxalidaceae); used as a hemostatic in veterinary medicine, but toxic in elevated levels when ingested by humans; also used in the removal of ink and other stains, and as a general reducing agent; salts of oxalic acid are found in renal calculi; accumulates in cases of primary hyperoxaluria.

oxalic acid

/ox·al·ic ac·id/ (ok-sal´ik) a dicarboxylic acid occurring in various fruits and vegetables and as a metabolic product of glyoxylic or ascorbic acid; it is not metabolized but is excreted in the urine. Excess may lead to formation of calcium oxalate calculi in the kidney.

oxalic acid (H2C2O4)

[oksal′ik]
a member of a family of dibasic acids found in many common plants, such as buckwheat, wood sorrel, and rhubarb. It is an important reagent and is used in bleaching and drying. Poisonous if ingested, oxalic acid is used in veterinary medicine as a hemostatic. In dietary intake of foods containing oxalic acid, the substance binds with calcium and is sometimes found in renal calculi and the urine of patients with hyperoxaluria. Also called ethanedioic acid.

oxalic acid

a poisonous, dibasic acid found in various fruits and vegetables, and formed in the metabolism of ascorbic acid. In plants the acid is present in the form of oxalate.
The commercial acid is highly toxic and if ingested should be neutralized by the administration of lime water (calcium hydroxide solution) or other convenient source of calcium, which reacts with the acid to form insoluble calcium oxalate.
