Blood stasis caused by anger is mostly due to internal injuries of emotions and feelings, depression and stagnation of qi (obstruction of qi’s movement). In Chinese medicine theory, stasis of blood is a pathological product of stagnation of blood in the body, and the normal operation of blood depends on the promotion of qi; if qi is not running smoothly and cannot move blood, then blood stops and stasis occurs. Therefore, anger can lead to blood stasis in the body. When the patient is angry, qi stagnation causes the blood in the body to run poorly, then the power to push the blood will gradually weaken, and when the blood mobility becomes poor, it will cause blood stasis in the body. Usually this condition is called qi stagnation and blood stasis (stagnation of blood due to the lack of smooth flow of qi). Therefore, patients are advised to pay attention to keeping a good mood and a calm mind in their daily life, and not to get angry easily. Seek medical advice promptly if the body does not adapt.
