Any chronic abscess that fails to heal for a long time is caused by cold pathogenic factors invading the meridians, leading to blood coagulation and stasis with obstructed circulation. The accumulation and knotting of these pathological products form an abscess. After the onset of the abscess, if the heat-toxin is not fully cleared and is subsequently attacked by wind-cold, the cold combats with the swelling, causing stagnation and knotting that cannot dissipate. Consequently, it persists without healing. If it remains unhealed for a long time, it may transform into a fistula (lou).
For treating chronic abscesses that fail to heal, characterized by the retention and accumulation of wind-toxic qi, pain in the sinews and bones, prolonged discharge of pus, and failure of the wound to generate flesh, the Wuxiang Liaoqiao San (Five-Aromatic Schisandra and Forsythia Powder) formula is suitable.
