Cinnamon Twig (Guizhi) three liang (peeled), White Peony Root (Shaoyao) three liang, Licorice Root (Gancao) two liang (roasted), Fresh Ginger (Shengjiang) three liang (sliced), Jujube (Dazao) twelve pieces (split).
The above five herbs are coarsely crushed. Boil with seven sheng of water over a gentle fire until three sheng remain. Strain the dregs. Take one sheng when the temperature is suitable.
Observe the patient for twenty-four hours after administration. If the symptoms persist after completing one dose, prepare and administer another dose. If sweating does not occur, administer the second or third dose. Avoid consuming cold, sticky, slippery, meat, noodles, five pungent spices, dairy products, and foul-smelling foods.

This is also a variation of Guizhi Tang, focusing on the Ying (Nutritive) level, a pure and unadulterated formula.
In reading the "Treatise on Cold Damage," conditions such as counter-flushing, worsening flushing, palpitations with irritability, all utilize Shaoyao Gancao Tang (White Peony and Licorice Decoction). The sour and sweet flavors transform into Yin to stop irritability. Observing the removal of Fresh Ginger and Jujube suggests avoiding Fresh Ginger's dispersal of the exterior and Jujube's cloying nature... [Text incomplete in source].
