Allantoin, also known as 5-ureidohydantoin or glyoxyldiureide, is a chemical compound naturally present in animal organs and plant leaves, and in bacteria as well. Allantoin can be extracted from natural sources and chemically synthesized.  At present, natural allantoin is mostly extracted from the comfrey plant, and the synthetic allantoin is mostly obtained from glyoxylic acid and urea.
