The Tannic acid helps to form a blood clot by contracting blood vessels. Amr ^_^

Actually, blood clotting is the result of a "cascade" effect of different factors in the blood. Once activated they "domino" -- one activates the next in the chain -- until the blood clots. There are two pathways to blood clotting (coagulation) -- an intrinsic pathway and an extrinsic (external) pathway. Tannic acid acts to activate the extrinsic pathway and set the factor "cascade" in motion to clot the blood.
