Insect-Ant-Collateral-Unblocking Method for Treating Microvascular Angina
Microvascular angina(MVA)belongs to the category of"chest obstruction"and"heart pain"in TCM,with the affected area being the heart's collateral vessels.The collateral vessels facilitate the circulation of qi and blood,harmonize the defense and nutrient qi,and maintain internal and external harmony within the body.When pathogenic qi invades the small collateral vessels,it gradually leads to stagnation.If the body's healthy qi is insufficient,pathogenic qi becomes excessive,generating phlegm and stasis that transform into toxins,disrupting the functions of the zang-fu organs and causing abnormal circulation of qi and bloodfailure to expel physiological and pathological by-products,which exacerbates the pathogenic qi,damaging the body and forming toxins.The treatment principle should focus on promoting blood circulation to remove stasis,eliminating phlegm and promoting urination,detoxifying,and unblocking the col-laterals.Insect-based medicines,which are considered products of blood and flesh with potent properties,are known for their strong dis-persing and penetrating nature and are commonly used for treating conditions where prolonged illness enters the collateral vessels or when meridians are obstructed.Blood stasis and phlegm are important pathological factors in the development of chest obstruction,and insect-based medicines,due to their wriggling characteristics,can scrape away phlegm and stasis,removing the old to make way for the new.Besides,qi-tonifying,yin-nourishing,and healthy qi-supporting Chinese medicines can enhance the effects.Pathological products such as phlegm and blood stasis adhere to the blood vessels over time,damaging the heart,so treatment should focus on dissolving phlegm and dispelling stasis.Insect-based medicines such as Wugong(Scolopendra)and Quanxie(Scorpio)have potent properties with significant effects in detoxifying and resolving masses.
