7 herbs·from Shanghan Lun (Treatise on Cold Damage)
In the《Shanghan Lun》tradition, this formula is described for a Taiyang-stage pattern of fever with aversion to cold — the heat more than the cold — and a faint, weak pulse, a state the text marks as lacking yang, in which strong sweating is cautioned against. A historical indication, not a modern diagnostic or treatment recommendation.
