Scabs are formed when chemical proteins react with special blood cells called platelets, which cause the blood to get sticky and clump together. Once you've clotted, lots of different chemicals and cells work together to dry out the clot and form a scab, keeping out germs while the cells underneath repair themselves. So, if you pick a scab you're messing with all your body's hard work!
