Pineapple stems that show anti-tumour activity

Scientists at the Queensland Institute of Medical Research (QIMR) have discovered two molecules from pineapple stems that show anti-tumour activity in laboratory studies. One molecule called CCS blocks a protein called Ras, which is defective in approximately 30% of all cancers. The other molecule called CCZ, stimulates the body's own immune system to target and kill cancer cells.
