1. Dr Lawrence Williams, adjunct professor in the College of Health Sciences at the University of Technology, says he and his business partner have obtained a United States patent for an anti-cancer formulation based on the guinea hen weed.
    The Jamaican scientist says he now expects to make headway on a buyout offer that he has spoken of for at least three years, but is yet to finalise with business partner PG Pharma LLC, based in Michigan, United States.
    The patent is the end stage of 28 years of research into the indigenous guinea hen weed plant of Jamaica, scientifically known as petiveria alliacea. It is shared with co-researcher Dr H. George Levy, who owns PG Pharma.
