5 herbs·from Shanghan Lun (Treatise on Cold Damage)

In the Shanghan Lun (《傷寒論》, Treatise on Cold Damage) tradition, this formula is described for the Taiyang wind-attack presentation: a pulse floating at the surface yet weak in the depth, spontaneous fever and spontaneous sweating, shivering aversion to cold, aversion to wind, a mild creeping fever, stuffy noisy breathing, and dry retching. A historical indication, not a modern diagnostic or treatment recommendation.
