According to Traditional Chinese Medicine (TCM), chronic idiopathic thrombocytopenic purpura is caused by dysfunction of the organs such as the heart, spleen, liver, and kidneys. This leads to blood heat causing reckless circulation of blood, or yin deficiency with internal heat, or spleen and kidney qi deficiency, etc. For patients whose platelet count is above 30,000 to 40,000 and who do not have significant bleeding, pure traditional Chinese medicine can be used for adjustment and treatment. The characteristics of this approach are minimal side effects and fewer relapses.
