Pomegranate - cancer cell killer

Here is an article on one of my childhood favorite fruit. Did not says the extract from the juice or the seed kills cancer cell. My guess is from the seed. so bite the seed and swallow like watermelon/ grapes seeds which are good for you

A new study by University of Wisconsin Medical School researchers states that pomegranate juice may fight against prostate cancer, which is the most common invasive cancer. Previous studies have shown that pomegranate is rich in anti-oxidant and anti-inflammatory activity and is effective against tumors in mouse skin. In fact, pomegranate juice has higher anti-oxidant activity than do red wine and green tea, both of which appear promising as anti-cancer agents. The UW research team aimed to find out if the extract from pomegranates would not only kill existing cancer, but help prevent cancer from starting or progressing. Using human prostate cancer cells, the team first evaluated the fruit extract's effect, at various doses, on those cells cultured in laboratory dishes. They found a 'dose-dependent' effect - in other words, the higher the dose of pomegranate extract the cells received, the more cells died. The research team then progressed to tests in mice that had been injected with prostate cancer cells from humans and developed malignancies. The 24 mice were randomly divided into three groups. The control group received normal drinking water, while the animals in the second and third groups had their drinking water supplemented with .1 percent and .2 percent pomegranate extract respectively. The doses for the mice were chosen to parallel how much pomegranate juice a typical healthy human might be willing to eat or drink daily. The mice receiving the higher concentration of pomegranate extract showed significant slowing of their cancer progression and a decrease in the levels of prostate-specific antigen (PSA), a marker used to indicate the presence of prostate cancer in humans. The animals that received only water had tumors that grew much faster than those in the animals treated with pomegranate extract. "Our study, while early, adds to growing evidence that pomegranates contain very powerful agents against cancer, particularly prostate cancer. There is good reason now to test this fruit in humans - both for cancer prevention and for treatment," said lead researcher Dr Hasan Mukhtar.
