Thrombocytopenic purpura includes two types., primary and secondary. Primary thrombocytopenic purpura is a hemorrhagic disease caused by decrease of platelets for unknown cause and is related with immunity, while secondary thrombocytopenic purpura usually follows other diseases. Clinically, the disease is characterized by petechiae and ecchymosis in skin and mucosa or hemorrhage in viscera, absolute decrease of the number of platelets, the normal or increased number of megalocaryocytes in bone marrow accompanied by disturbance of maturity. This disease can be divided into acute type and chronic type according to the clinical manifestations and courses. Acute type is commonly found in children and the incidence in males is similar to that in females, while chronic type is often seen in young women and the ratio of incidence between males and females is 1:3 - 4. The severity of hemorrhage varies with the platelet count. In serious cases, there may be intracranial hemorrhage which may cause death. According to the clinical manifestations, the disease is categorized in TCM as "xue zheng" (hemorrhagic syndrome), "fa ban" (purpura), "pu tao yi" (cyanosis), etc. Its cause lies in heat, toxic substance, blood stasis and deficiency. The major pathogenesis is that hyperactivity of heat and toxic substances or insufficiency of qi and yin forces the blood to move recklessly, resulting in blood extravasating from vessels.
