Scientists have confirmed more than 20 local plant species are effective against many of the top killer cancers today.
During a three-day annual scientific conference of Kenya Medical Research Institute (Kemri), more than 30 researchers left no doubt that the country has immense capacity to deal with cancer from its plant resources.
Most of the plants the scientists reported are widely used locally for medicinal purposes and many specifically for treating cancer.
“Over 60 per cent of currently used anti-cancer agents are derived from natural sources,” explained Sabina Wangui Wachira of Centre for Traditional Medicine and Drug Research at Kemri.
“Our work was to provide scientific evidence to support claims that some Kenya medicinal plants are active against cancer.”

Warburgia stuhlmannii – (stem bark extract) acted against colon cancer cells
A combination of Tamarindus indica (fruit) and Pennisetum glaucum (grain) was active against liver and prostate cancer cells
The plants Plumbago zeylanica, Myrsine africana, Maesa lanceolata, Rapanea melanphloes and Aloe saponaria showed strong action against lung, colon, breast and liver cancers when used either singly or in various combinations
