Cucurbitin is an amino acid and a carboxypyrrolidine that can eliminate parasitic worms.[1] It is found in Cucurbita seeds.[2][3] In 1992, a patent was filed to use the (-)-enantiomer in cosmetics and pharmaceuticals.[4] Cucurbitin is found in uncooked pumpkin seeds.[5]
Cucurbitin is an inhibitor of histidine decarboxylase, which is associated with inhibition of the biosynthesis of histamine responsible, among other things, for the formation of the inflammatory response.[6] It is used in cosmetics for dry and sensitive skin and for the treatment of schistosomiasis. Cucurbitin causes degenerative changes in the reproductive organs of parasitic flatworms called flukes.[7][8]
