“…In modern medical research, the pathogenesis of cerebral ischemia includes energy metabolism disorders, platelet aggregation, vasoconstriction and microcirculation disorders, excitatory amino acid toxicity and so on, and the drugs clinically used for the preventing and treating cerebral ischemia are mainly antiplatelet drugs aspirin, ticlopidine and other drugs. Most cerebral ischemia patients need a long time of medication, but the side effect from long-term medication, drug prices, limitations of treatment course will affect the treatment of the disease (Atta et al, 2017, Halim et al, 2017). Chinese medicine believes that the occurrence of ischemic stroke relates with the Qi stagnation, Qi deficiency, phlegm turbidity, blood stasis, Yin deficiency, heat or Fire and other factors, so, clinically, some therapeutic principles like “tonifying Qi and reinforcing deficiency”, “activating blood and resolving stasis”, “clearing heat and expelling toxin” and others are adopted to prevent cerebral ischemic diseases.…”
