[Guizhi Tang (Cinnamon Twig Decoction)] Treats Taiyang Wind Strike (Taiyang Zhongfeng), characterized by floating Yang pulse, weak Yin pulse, fever, sweating, aversion to cold, nasal congestion with roaring sound (Biming), and dry retching. (Modern "common cold" is referred to as "Wind Strike" in ancient texts).

Herbs: Guizhi (Cinnamomi Ramulus, bark removed, do not roast over fire), Shaoyao (Paeoniae Radix Alba, each 1.5 liang), Gancao (Glycyrrhizae Radix et Rhizoma, 1 liang, honey-fried).

Preparation and Administration: Crush the herbs into coarse pieces. Take 5 qian, add 1.5 sheng of water, 3 slices of Shengjiang (Zingiberis Rhizoma Recens), and 1 Zao (Jujubae Fructus). Simmer together until reduced to 0.8 sheng, strain, and take warm. If the disease occurs in the second or third month and is a Warm Disease (Wenbing), Yangdan Tang is appropriate.

[Mahuang Tang (Ephedra Decoction)] Treats Taiyang Disease presenting with headache, fever, body ache, aversion to wind, absence of sweating, and wheezing.

Herbs: Mahuang (Ephedrae Herba, nodes removed, soaked in boiling water, yellow juice discarded, dried, 1.5 liang), Xingren (Armeniacae Semen Amarum, 35 seeds, skin and tips removed), Guizhi (Cinnamomi Ramulus, bark removed, do not roast over fire, 1 liang), Gancao (Glycyrrhizae Radix et Rhizoma, half liang, honey-fried).

Preparation and Administration: Crush the herbs into coarse pieces. Take 5 qian per dose. Add 1.5 sheng of water, simmer until reduced to 0.8 sheng, strain, and take warm. Cover with blankets to induce slight sweating. There is no need to drink hot congee to assist the medicinal effect.

Modifications: For Shanghan (Cold Damage) and Heat Diseases, the nature of the medicine should be cool, not overly warming. After the Summer Solstice, when using Mahuang Tang, one must add Zhimu (Anemarrhenae Rhizoma, half liang), Shigao (Gypsum Fibrosum, 1 liang), and Huangqin (Scutellariae Radix, 1 fen).

Formula Theory: There is no treatise more definitive than Zhang Zhongjing’s discussion on treating Shanghan. The first is Guizhi Tang, the second is Mahuang Tang, and the third is Daqinglong Tang. Guizhi Tang treats Wind Strike; Mahuang Tang treats Cold Damage; Daqinglong Tang treats... [Text fragment/corruption here]. If the syndrome involves Ying (Nutritive Qi) circulating within the vessels and Wei (Defensive Qi) circulating outside... Zhang Zhongjing uses Guizhi as a herb to disperse from the muscle layer. Therefore, regarding the Guizhi Tang syndrome, Zhang Zhongjing states: "It is better if there is a slight, continuous sweat covering the whole body; it should not be profuse like flowing water." One knows that for Wind Strike with sweating, one must not induce heavy sweating; excessive sweating will disturb Ying Blood, because Ying Qi circulates within the vessels. Cold pathogens reside within the vessels... thus leading to fever without sweating, dry teeth, and inner vexation. This is a disorder of Ying and Wei. Generally, both these medicines are diaphoretic agents. How to verify this? In Zhang Zhongjing's *Gui Zhi Chapter 19*... it is because Wei Qi does not harmonize with Ying Qi. Since Ying circulates within the vessels, *Chapter 47* states: "Fever and sweating is named Wind Strike." In Wind Strike with sweating, Ying is harmonious but Wei is disharmonious. Also in *Volume 1*... Wind injures Wei, Cold injures Ying. If both Ying and Wei are diseased, causing bone and joint soreness, sweating should be induced. Thus, it is known that in Shanghan with a floating and tight pulse, both Ying and Wei are diseased; therefore, Guizhi is used concurrently in Mahuang Tang. This is Zhang Zhongjing’s intent. As for Daqinglong Tang, although it treats Wind Strike presenting with Cold pulses, or Cold Damage presenting with Wind pulses, Zhang Zhongjing says: "Those with sweating and aversion to wind must not take it; taking it may lead to cold limbs (Jue Ni) and symptoms of muscle twitching (Jin Ti Rou Yun)." Therefore, the indication for Daqinglong Tang is particularly difficult to apply correctly; it can only be used when the form and syndrome match precisely. Hence, in the case treated by Doctor Wang Shi, only Guizhi Mahuang Ge Ban Tang (Half-Guizhi Half-Mahuang Decoction) was used, demonstrating careful deliberation.
