Yi Qi Xian
Yi Qi Xian Uses, Dosage, Side Effects, Food Interaction and all others data.
Yi Qi Xian increases cerebral metabolism; it increases glucose and O2 consumption; improves cerebral hypoxia tolerance; shifts glucose metabolism to the energetically more favourable aerobic pathway, but it increases the anaerobic pathway as well; it elevates the ATP concentration and the ATP/AMP ratio in the brain, and elevates the cerebral norepinephrine, dopamine and serotonin levels.
Yi Qi Xian considerably improves cerebral microcirculation by inhibiting platelet aggregation, reducing the pathologically increased blood viscosity, and increases erythrocyte deformability. It also promotes O2 transport into the tissues by reducing the O2 affinity of erythrocytes.
It selectively and intensely increases cerebral blood flow and the share of the brain in cardiac output, it reduces cerebral vascular resistance without affecting systemic circulation (blood pressure, heart rate, cardiac output, total peripheral resistance). It does not elicit steal phenomenon; on the contrary, it primarily improves the blood supply of the injured and ischaemic area while it remains unchanged in the intact areas (inverse steal effect). It further increases blood flow which is already increased as a result of hypoxia.
