Crocodillin: The Powerful Healing Peptide from Crocodiles

Proteins consist of smaller units called peptides. The protein peptide crocodillin occurs in the blood of Crocodylus porosus, a crocodile native to Australia, Indonesia, and the Philippines. Crocodillin possesses powerful antimicrobial properties.

Effect on Crocodiles

• Crocodiles often suffer serious wounds, especially in fights with their fellow crocodiles. But in spite of the septic conditions of the water in which they live, their wounds heal quickly. Crocodillin brings about their rapid recovery, according to Dr. Adam Britton.

Antimicrobial Effects

• In 1998 Dr. Gill Diamond isolated crocodillin from crocodile blood. He found it killed many bacteria, even resistant strains of Staphylococcus aureus, according to Dr. Adam Britton.

No Cure Yet

• Dr. Britton and others have been trying to develop an effective medical preparation of crocodillin that is safe for human use, but so far their efforts have not been successful, according to "National Geographic News." Some crocodile protein peptide products are currently on the market, but their medical value is questionable, according to Dr. Ray Sahelian, M.D.
