Treatment for back carbuncles that healed after a year but recurred. This is due to severe wind pathogens or stagnant qi internally causing blockage of the meridians. From summer onwards, the pathogen attacks outward on the back. If left untreated for a long time, accumulation turns into pus and blood, forming an internal leaking sore. Formula:
