In 1821, the french chemist jean louis lassaigne found it in the fluid of the allantois; he called it “l’acide allantoique”. In 1837, the german chemists friedrich wöhler and justus liebig manufactured it from uric acid and renamed it “allantoïn”.

However, ongoing research studies recommend that there might exist a histological wound recovery profile induced by allantoin in rats that causes the amelioration and fastening of the reestablishment of normal skin. This facilitation of injury healing is supported by observations that injuries caused to rat subjects to which topical allantoin preparations were applied histologically demonstrated increased vasodilation, existence of inflammatory exudates, variety of inflammatory cells, angiogenesis, fibroblast proliferation, and increased collagen deposition when compared to rat subjects with injuries that did not receive any allantoin administration.


In studies on human topics, a healing of 19% and 34% of allantoin in the urine was observed however only in 2 people and just after the administration of huge doses of allantoin. After intravenous administration, healing in the urine was almost quantitative with dosages of 75 to 600 mgm in the human design. After 240 mgm, excretion continued for 72 hours in human subjects and the results were comparable in regards to subcutaneous injection. [4]
