Study on the Application of Collateral Disease Differentiation and Treatment in Acute Conditions Based on the Theory of"Both Meridians and Collaterals Governing Blood"
Meridians and collaterals are not only the sites where qi and blood are regulated,transformed,and distributed for nourish-ment,but also the channels through which information is transmitted and pathogens enter or exit.The general sequence of pathogenic transmission after invasion into the human body is from the skin and hair to yang collaterals,meridians,six fu organs,five zang organs,until yin collaterals.Collateral diseases can be caused not only by chronic illnesses but also by acute conditions.Acute collateral disea-ses are characterized by a rapid onset,severe conditions,and both exterior and interior of the body being affected by pathogens.When yang collaterals are affected,wind pathogen predominates,leading to disharmony of qi and blood and collateral stasis.As stated,"To treat wind,first treat blood,for when blood flows,the wind dissipates,"the treatment should focus on expelling pathogens and unblock-ing the collaterals.Expelling pathogens often involves using wind-dispelling drugs,while unblocking collaterals follows Ye Tianshi's method of pungent-moistening to smooth the collaterals.When pathogens enter yin collaterals,they often damage the zang organs,form-ing blood stasis,fluid retention,or necrotic tissue,which further obstructs the qi movement of the organs and affects their functions.In such cases,the primary treatment principles are to expel pathogens,detoxify,and unblock the collaterals,using salty and cold drugs that enter the blood collaterals to clear blockages and restore the flow of qi and blood,thereby achieving the goal of eliminating pathogens.For acute cerebral infarction with obstruction of the brain collaterals,treatment should focus on calming the liver,extinguish wind,dissol-ving stasis,and unblocking the collaterals,so Modified Gastrodia and Uncaria Decoction combined with Peach Kernel and Carthamus Four Substances Decoction can be used.For chest pain due to stasis in the heart collaterals,the treatment should focus on tonifying qi,nourishing yin,invigorating blood,and unblocking the collaterals,so Modified Blood Mansion Stasis-Expelling Decoction combined with Celestial Emperor Heart-Supplementing Elixir can be used.For epidemic diseases with obstruction in the lung collaterals,the treatment should focus on resolving dampness,detoxifying,expelling pathogens,and unblocking the collaterals,so Modified Lung-Clearing Toxin-Resolving Decoction can be used.
