Shark liver oil

Sharks typically targeted for their liver oil include the school and gulper shark, and the basking shark (pictured).[1] All three of these species are either endangered[2][3] or critically endangered[4] due to overfishing according to the IUCN, although a legal targeted fishery for basking sharks no longer exists.[2]

Shark liver oil is an oil obtained from the livers of sharks. It has been used for centuries as a folk remedy to promote the healing of wounds and as a remedy for respiratory tract and digestive system problems.[5][6] It is still promoted as a dietary supplement, and additional claims have been made that it can treat other maladies such as cancer, HIV, radiation sickness, swine flu, and the common cold.[5][7] To date, none of these claims has been medically validated and shark liver oil (alone) is not a medication prescribed or utilized by American physicians.[7] However, it is a component of some moisturizing skin lotions[6] and hemorrhoid medications.[8][9]
