Qingchuan Decoction,From *The Secret Formulas of the Blue Sack*, Volume 2.,When a person develops a phlegm mass in the nape of the neck that is as hard as stone, over time it transforms into scrofula, oozing pus and blood. Before one mass has dissipated, another grows; before one has been seen, another ulcerates—whether beneath the ear, in the clavicular fossa, or on the shoulder—moving in a wandering, chain-like pattern. Hence it is called “Rat Sore” or “Chain Sore.”

Benefits
When a person develops a phlegm mass in the nape of the neck that is as hard as stone, over time it transforms into scrofula, oozing pus and blood. Before one mass has dissipated, another grows; before one has been seen, another ulcerates—whether beneath the ear, in the clavicular fossa, or on the shoulder—moving in a wandering, chain-like pattern. Hence it is called “Rat Sore” or “Chain Sore.”
Instructions for Use
Decoct in water and take orally. After 6 doses, the phlegm mass will gradually dissipate; after another 10 doses, the scrofula will be completely resolved; and after one month of continued treatment, the patient will be fully cured. Following recovery, take several dozen doses of Liu Junzi Decoction as a follow-up measure to ensure the condition never recurs.
