7 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 a case where, after a Taiyang illness has run its course and been wrongly purged, a Chaihu (Shaoyang) presentation still persists: incessant retching, a tense bound sensation below the heart, and a smouldering, mild vexation. A historical indication, not a modern diagnostic or treatment recommendation.
