Results General fatigue, weariness and no desire to speak, quadriplegia, megrim, acroanesthesia and so on, which reflect the main symptoms of MS, with occurrence frequency of above 60 percent. Five basic symptoms:Syndrome of haemostasis blocking collaterals (18.0%), dark purple tongue is the most important factor;Syndrome of dampness-heat blocking collaterals (17.2%), yellow greasy furred tongue is the important factor;Syndrome of yin-asthenia and obstruction of collateral (14.8%), rapid and thining pulse is the important factor;Syndrome of endogenous wind of liver and obstruction of collateral due to wind-phlegm (14.1%), physical convulsion is the important factor;Syndrome of asthenia of both qi and blood, and channel qi unfavorable (35.9%), feeble pulse is the important factor. Conclusion The location of MS is channels and collaterals.
