Imperata 10 by Seven Forests, also known as Mao Gen Zhi Xue Pian, clears heat.
Imperata 10 is designed to inhibit bleeding and is based on Ningxue Tang (Blood Calming Decoction), with agrimony, biota leaves, rehmannia, and imperata. From the traditional viewpoint, bleeding may occur when there is too much heat in the blood, causing the blood to flow "recklessly" and escape the vessels (treated by cooling herbs, such as raw rehmannia, scute and imperata). The blood cooling herbs are combined with hemostatics, such as lotus node, cephalanopolus, and biota leaf. Some herbs are said to have both properties: sophora flower and sanguisorba cool blood and are hemostatic.
