When the Wei Qi (Defensive Qi) is awake, it circulates in the Yang aspects; when asleep, it circulates in the Yin aspects. Therefore, somnolence (excessive sleepiness) belongs to Shaoyin disease (disease of the Foot-Shaoyin Kidney channel). If a patient desires to sleep but presents no exterior or interior symptoms, with a harmonious body condition and a small pulse, this indicates that the pathogen is resolving. Wind-warmth syndrome also manifests as somnolence and excessive sleep, but differs by presenting with a floating pulse, fever, sweating, heaviness of the body, and snoring breath.
This belongs to heat pathogen. If there is excess heat, Chengqi Tang (Gut-Purging Decoction) is appropriate; if there is deficiency heat, nourishing Yin is appropriate.
Shao’s Commentary: Dry mouth and throat belong to heat pathogen. However, heat has excess and deficiency types, so treatment must be distinguished accordingly.
The Shaoyin meridian ascends through the liver and diaphragm, follows the throat, and connects to the root of the tongue. Therefore, sore throat is listed exclusively in the Shaoyin chapter. For sore throat due to Shaoyin disease: those belonging to heat patterns include Banxia San Ji Tang (Pinellia Powder and Decoction), Gancao Tang (Licorice Decoction), and Jiegeng Tang (Platycodon Decoction), which are used to disperse fire. Those belonging to cold patterns include Guizhi Ganjiang Tang (Cinnamon Twig and Dried Ginger Decoction), used for treating yang collapse due to excessive sweating; and Tongmai Sini Tang (Pulse-Reviving Four Reversals Decoction), used for treating yin excess repelling yang. (Refer to *Yixue Zhunsheng*)
Shao’s Commentary: Heat-type sore throat is caused by rising deficient fire. Cold-type sore throat involves two conditions: yang collapse and yin repelling yang.
*Yizong Jinjian* states that sore throat can be either cold or heat. Swelling and pain indicate heat pattern; Zhang Zhongjing treated these with Ganjie Tang (Licorice and Platycodon Decoction), Banxia San (Pinellia Powder), Kujiu Tang (Bitter Wine Decoction), and Zhufu Tang (Pig Skin Decoction). Pain without swelling indicates cold pattern, best treated with Sini Tang (Four Reversals Decoction) plus Jiegeng (Platycodon).
Shao’s Commentary: Sore throat occurs in both cold and heat patterns; swelling indicates heat, lack of swelling indicates cold. Treatment must be distinguished.
Vomiting distinguishes between cold and heat. Heat patterns present with a rapid pulse at the Cunkou (radial artery position), fever, irritability, thirst, desire to drink water, yet vomiting immediately after drinking; Wuling San (Five-Ingredient Powder with Poria) is appropriate. Vomiting immediately after eating suggests using Erchen Tang (Two-Aged Decoction) added with ginger juice and stir-fried Huanglian (Coptis Rhizome) to harmonize.
Shao’s Commentary: Vomiting occurs in both cold and heat patterns. This section discusses heat vomiting, further divided into Shuini (Water-Reversal) syndrome and Tanre Geju (Phlegm-Heat Repulsion) syndrome.
Cold patterns present with vomiting without thirst; Lizhong Tang (Middle-Warming Decoction) with Baizhu (Atractylodes Rhizome) removed and fresh ginger added is appropriate. (Refer to *Yixue Zhunsheng*)
Shao’s Commentary: This is the standard method for treating cold vomiting. Shelian (Stone Lotus Seed) and Dingxiang (Clove) may also be added.
*Yizong Jinjian* states: Lack of thirst, cold limbs, and vomiting indicate cold pattern, suitable for Lizhong Tang or Wuyu (Evodia) formulas. Thirst with immediate vomiting after eating indicates fire/heat; excess heat is treated with Huanglian Jiedu Tang (Coptis Detoxification Decoction), while deficiency heat is treated with Ganjiang Huangqin Huanglian Tang (Dried Ginger, Scutellaria, and Coptis Decoction). Thirst with desire to drink, vomiting after drinking, and recurring thirst indicates Shuini (Water-Reversal) syndrome, treated with Wuling San.
Shao’s Commentary: In vomiting, lack of thirst indicates cold, while thirst indicates heat. Heat patterns further distinguish between excess and deficiency.
