Many will tell you that green tea is good for your health, but researchers at Singapore's A*STAR might just make it a literal life-saver. They've developed nanoscale drug delivery "missiles" that use a key ingredient from green tea, epigallocatechin gallate (EGCG), to kill cancer tumors more effectively. Compounds based on EGCG both shield the drug carriers from your immune system and provide some therapy of their own; in other words, these hunters are more likely to reach tumors and do a better job of healing your body when they arrive. They're also less prone to accumulating in organs where they aren't wanted, so there are fewer chances of nasty side effects. It's not certain when these tea-based transporters will be available to your doctor, but A*STAR's team is determined to make them a practical reality before long. via Engadget.
