Abstract： This paper introduces the experience of chief physician LIN Daoqiang in the syndrome differentiation and treatment of numbness and impediment. LIN believes that the pathogenesis of numbness and impediment lies in qi- blood deficiency and dystrophy of limbs, meridian and collateral, and skins, or the obstruction of meridian and collateral caused by external pathogens(wind， cold， dampness， heat) and pathological products of phlegm and stasis， resulting in stagnant movement of qi and blood as well as dystrophy of limbs，meridian and collateral，and skins. The disease can be classified into four syndrome types， namely qi- blood deficiency and blood stasis obstructing the collateral， liver- kidney depletion and blood stasis obstructing the collateral，cold-dampness-blood stasis and impediment obstructing meridian and collateral，as well as retained dampness- heat and impediment obstructing meridian and collateral. And the treatment can be carried out based on the syndrome differentiation. The treatment of deficiency syndrome is mainly to tonify qi and blood，or to nourish the liver and the kidney；that of the excess syndrome should focus on resolving stasis and diffusing impediment，warming the collateral and dissipating cold，as well as clearing heat and draining dampness；deficiency- excess complex should be treated by supplementing deficiency and purging excess. Therefore，physicians should pay attention to the protection of the spleen and stomach，proper treatment based on the understanding of the cause of disease，the treatment of warming yang and activating blood， and the proper use of meridian entry medicine， couplet medicinals， insect medicine and rattan medicine.
