7 herbs·from Shanghan Lun (Treatise on Cold Damage)
In the《Shanghan Lun》tradition, this formula is described for a Taiyang pattern of eight or nine days with an intermittent-fever-like rhythm — fever and chills, the heat more than the cold, two or three bouts a day — a flushed complexion, and itching of the body for want of a light sweat. A historical indication, not a modern diagnostic or treatment recommendation.
