From Hoodia Gordonii to P57

CSIR isolated the hunger-suppressing chemical component in Hoodia Gordonii, now known as P57. Patented it, In 1997.

CSIR licensed the UK-based firm Phytopharm to further develop and commercialize P57.

It has been established that P57 works fooling the brain into thinking it is full, even when it is not, therefore curbing the appetite.

The following year, Phytopharm licensed drug giant Pfizer to develop and market P57.
