Descriptions

Calcium oxalate is a chemical compound that forms needle-shaped crystals. Large quantities are found in the painfully poisonous plant dumb cane. It is also found in rhubarb leaves, various species of Oxalis , and agaves, and (in lower amounts) in spinach. Most kidney stones are caused by calcium oxalate. All Arums typically have unique flowers, consisting of a pike of reduced male or female organs, or both, surrounded by a showy petal-like leaf, a bract, which is often colorful. The toxic parts are the leaves. They contain calcium oxalate, a compound derived from oxalic acid, as well as enzymes which trigger the release of antibodies called histamines in the bloodstream of persons who ingest the leaves. Oxalates are needle-like crystals, which, when eaten, may pierce the mouth, throat and digestive tract as they pass through, causing, at the very least, intense discomfort. Nonsoluble calcium oxalate crystals are found in plant stems, roots, and leaves. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

Calcium oxalate (Ca[COO]2) crystals are the most frequently observed crystals in urine, and 75% of renal calculi have calcium oxalate as a component. Calcium oxalate crystals can form at any pH and have various microscopic morphologies. It is estimated that about half of the oxalate in urine comes from ascorbic acid (vitamin C), which is a precursor to oxalate. Calcium oxalate crystals are also associated with ethylene glycol ingestion, another oxalate precursor. Source: Regenstrief LOINC, Wikipedia: Calcium oxalate
