5 herbs·from Shanghan Lun (Treatise on Cold Damage)
In the《Shanghan Lun》tradition, this formula is associated with a "running-piglet" (奔豚) pattern: after fire-needling to induce sweat, the needle sites take cold and rise red, and a surge of qi is felt rushing up from the lower abdomen toward the heart. A historical indication, not a modern diagnostic or treatment recommendation.
