Signs and symptoms are aversion to cold, general fever, headache, absence of sweating, chest and epigastric fullness and distress, lack of appetite, a thin and white tongue coating and a superficial pulse. |
【Pathogenesis】 |
Wind-cold pathogens exist all year round. This formula is indicated for a mild pattern of externally contracted wind-cold at the superficial level with internal qi constraint. The symptoms such as aversion to cold, fever, headache, absence of sweating, a thin and white tongue coating and a superficial pulse are typical manifestations of an exterior pattern. Lack of appetite, distress and fullness in the chest and abdomen reveal qi constraint. The proper treatment is to release the exterior and rectify qi. Because the impact of the external pathogens is mild, it is “appropriate [to apply] light, relaxing and soothing [medicinals] , not ones with drastic effect”《Treatise on Medical Formulas》Volume One, Yi Fang Lun. |
