• Though Gua lou is sweet and cold, it is used for chest Bi due to Qi stagnation and blood stasis and/or chest Yang deficiency. Though Gua lou is sweet, it does not supplement, nor produce Qi stagnation. Though it is cold, it does not cause obstruction. In cases of chest Yang deficiency or stagnation, Gua lou is combined with herbs that balance its cold nature, such as Xie bai, Bai jiu, Gui zhi, and Tan xiang.

– 1. Constipation due to fluid dryness of the large intestine and/or Qi stagnation.

Chest Bi with oppression of the chest and epigastrium, cough, profuse phlegm, piercing pain in the chest radiating toward the back, and shortness of breath due to accumulation of turbid phlegm blocking the Qi and Yang of the chest.

(Gua Lou Xie Bai Bai Jiu Tang) For these indications, the combination can be favorably reinforced by adding Dan shen, San qi, Tan xiang, and Gui zhi. The Gua lou should be stir-fried until scorched.
