Cinnamon Twig (Liangzhi Shiqi Zhu, peeled) Paeonia Root (Liangliu Zhu) Licorice Root (Liangliang Er Zhu, roasted) Apricot Seed (Shi Liu Mei, skin and tip removed) Ephedra Stem (Shiliu Zhu, nodes removed) Fresh Ginger (Liangliu Zhu) Jujube (Wu Mei, split) The above seven ingredients are decocted with five sheng of water. First, boil Ephedra Stem for one or two boils, remove the foam on the surface, then add the remaining herbs. Decoct until two sheng of liquid remain, strain, and take one sheng warm, twice a day. Another version states: Two sheng of Guizhi Tang (Cinnamon Twig Decoction) and one sheng of Mahuang Tang (Ephedra Decoction) are mixed to make three sheng, taken in two doses. Now combined into one formula, the regimen is as described previously.

After taking Guizhi Tang (Cinnamon Twig Decoction), if there is profuse sweating and a flooding pulse, although sweat is produced, the pathogenic factor is not yet exhausted. Administer Guizhi Tang (Cinnamon Twig Decoction) according to the previous method. This refers to the situation where the pathogen remains, and treatment should proceed according to this method again.

If the symptoms resemble malaria, occurring twice a day, resolution will occur through sweating; Gui Zhi Er Ma Huang Yi Tang (Two Parts Cinnamon Twig and One Part Ephedra Decoction) is indicated. This shares a similar intent with Guizhi Mahuang Banji Tang (Half-Part Cinnamon Twig and Half-Part Ephedra Decoction), but because it follows profuse sweating, the dosage of Cinnamon Twig is slightly heavier, while that of Ephedra Stem is slightly lighter.

This formula consists of Guizhi Tang (Cinnamon Twig Decoction) plus Ephedra Stem and Gypsum.
Cinnamon Twig (peeled) Paeonia Root Licorice Root (roasted) Ephedra Stem (nodes removed, each eighteen zhu) Jujube (four pieces, split) Fresh Ginger (Liangliang Er Zhu, sliced) Gypsum (Ershi Si Zhu, crushed and wrapped in cotton) The above seven ingredients are decocted with five sheng of water. Boil Ephedra Stem for one or two boils, remove the foam, add the other herbs, and decoct until two sheng remain. Strain and take one sheng warm.
Appendix: Yuespi Fang (Yuebi Decoction): Ephedra Stem six liang, Licorice Root two liang, Gypsum half jin, Fresh Ginger three liang, Jujube fifteen pieces.

In Taiyang Disease (Disease of the Taiyang Channel), characterized by fever and aversion to cold, with more heat than cold and a faint pulse, this indicates Wu Yang (Absence of Yang). Sweating should not be induced further. This "Wu Yang" differs from Wang Yang (Yang Collapse) and also from general Yang Xu (Yang Deficiency) mentioned elsewhere. It implies that the patient's constitution was never robust, and the pathogenic factor is mild, resulting in alternating chills and fever with a faint pulse. If sweating were induced, it would likely lead to symptoms such as crossing hands over the heart and palpitations below the umbilicus. Therefore, this decoction clears and disperses the Ying and Wei (Nutritive and Defensive levels), allowing resolution through slight perspiration. Moreover, since heat predominates over cold and the heat resides in the Qi Fen (Qi Level), Gypsum is particularly suitable. Such is the prudence of ancient sages in prescribing herbs.

Regarding the above three formulas, the terms "one," "two," and "half-part" do not align precisely when calculating dosages based on the prescriptions. The reason for this discrepancy is unknown. Some suggest that the base formulas are decocted separately and mixed in ratios of one part or two parts before administration, which is another valid method. However, given that specific weights are noted for each herb within the formula, the rationale remains unclear. This point is preserved for further study.
