Green tea affects clotting. You should avoid any substance which increases the chance for bleeding prior to and after surgery. This includes garlic, onions, ginger, alcohol, high Vit. E brown seaweed, citrus fruits. Increased blood around breast implants has a higher chance for capsule contracture.
Green tea as everybody has written increase the time it take one to clot. It seems to work by making your platelets less sticky. We make platelets everyday. When we take aspirin, green tea and other things the platelets are affected for their entire life span (approximately ten days). So we try to get patients to stop these meds and herbs for ten days pre-op and at least ten days post-op.Check with your plastic surgeon for their advice. Good LuckStephen M.
