I found an interesting article that recommends ginger, curcumin and green tea for natural anti-cancer properties.
GreenMedInfo.Com has a wealth of information. I started off by viewing their video on the perils of vaccines and then came across the article about ginger
From the GreenMedInfo web site:
A study published in PLoS reveals a pungent component within ginger known as 6-shogaol is superior to conventional chemotherapy in targeting the root cause of breast cancer malignancy: namely, the breast cancer stem cells.
