Blood Stasis or Xue Yu (Xu = Blood; Yu = Stasis) is an important pathology of many disease processes in TCVM. Simply put, it means the flow of Blood is slowed down and brought to a static state. Normally, Blood is stored in the Liver and propelled by the Heart Qi to flow through the body. If Blood circulation is Stagnant or slowed down by certain factors, it will lead to retention of Blood in any part of the body or overflow of blood out of the vessels, resulting in Blood Stasis. Blood Stasis frequently occurs in long-term chronic illnesses. Blood Stasis, due to various etiologies may be the root of many age-related disharmonies. It can also be commonly observed after surgery or external traumatic injuries. Liver (in TCVM) is the most frequently affected organ by Blood Stasis. Other affected organs are the Heart, Lung, Stomach, and Intestines.
