Application of kumata kenin in preparation of abnormal vascular proliferation inhibition medicines

The invention discloses an application of kumata kenin in preparing abnormal vascular proliferation inhibition medicines. According to the application, kumata kenin serves as an abnormal vascular proliferation inhibitor, and can be used for treating diseases such as cancers, rheumatic arthritis, diabetic blindness and systemic lupus erythematosus which are caused by internal abnormal vascular proliferation. Experiments prove that the kumata kenin has an obvious inhibition function on the abnormal vascular proliferation. Consequently, the kumata kenin can be used for preparing the abnormal vascular proliferation inhibition medicines.
