Therefore, Chinese medicines for regulating blood conditions are considered to be effective, including Chinese medicines that can cool blood, nourish blood and promote blood circulation. Cooling-blood Chinese medicines are divided into those that can cool blood to be antipyretic and those that can cool blood to stop bleeding.
