Diabetic retinopathy is a capillary lesion of the retina, which may have insufficient blood supply. Thrombolysis can be used for retinal vein obstruction in the evidence of blood stasis and deficiency of qi and yin (both qi and yin are deficient), and needs to be used under the guidance of a doctor. Diabetic retinopathy is caused by long-term poor control of blood sugar in diabetic patients, which leads to systemic vasculopathy, thus leading to lesions of capillary endothelial cells, insufficient blood supply to the retina and neovascularization of the capillaries leading to vision loss. The ingredients of Thrombotoxin are Panax ginseng, Astragalus, Salvia miltiorrhiza and Xuan Shen. Its effect is to activate blood circulation and remove blood stasis (to promote blood circulation and eliminate blood stasis in the body), to benefit qi and nourish yin (to replenish qi and nourish yin), and it can be used for retinal vein occlusion of the retinal venous obstruction of the evidence of blood stasis and qi/yin deficiency (deficiency in qi and yin) and stable exertional angina pectoris, with contraindication for pregnant women and allergy sufferers, and it needs to be used under the guidance of a physician. Diabetic retinopathy requires medication and treatment under the guidance of a doctor, patients should not take medication without authorization.
