Anti-Cancer Properties Found in Jamaican Purple Yams
The UWI, Mona Campus officials said Dr. Dennis Bailey from the Biotechnology Centre made the discovery while conducting doctoral studies.
The study reportedly involved focus on indigenous varieties of yams cultivated in Jamaica, known as the Dioscorea alata, cultivar St. Vincent dark night, and moonshine yams.
Bailey told a UWI publication that purple yams contain potent phytochemicals that slow down the growth of cancer cells.
He says assessment of these tubers has revealed several properties that prevent the proliferation of cancer cells.
Bailey started his research on purple yams in 2002.
His test for the anti-cancer benefits involved experiments on rats.
Bailey says about 90 percent of the rats used as control died within 10 days of the experiment as their cancers kept spreading, while those fed with the anti-cancer yam extract survived.
