Fever, aversion to cold, and stiffness of the head and neck; the waist and spine clearly present opisthotonos (backward arching of the body). Convulsions (spasmodic twitching of limbs) and trismus (lockjaw) resemble epilepsy. This is named Ji disease (a disease characterized by spasticity and rigidity of the neck and back), which is its normal presentation. (Zhang Zhongjing stated: In Ji disease, there is fever, aversion to cold, stiffness and urgency of the head and neck, aversion to cold, sometimes redness of the head and face, redness of the eye vessels, only the head shakes, sudden trismus, and opisthotonos; this is Ji disease.) First, wind-cold is contracted, then dampness; the pulse corresponds to deep, slow, wiry, and fine. (Zhang Zhongjing stated: In Taiyang disease with fever, if the pulse is deep and fine, it is named Ji. *Qianjin Fang* stated: In Taiyang wind-stroke, if re-exposed to wind-cold and dampness, it transforms into Ji disease. Zhang Zhongjing also stated: If Taiyang disease undergoes excessive sweating, Ji disease results. Sun Shang stated: Ji disease with fever and a deep, fine pulse is difficult to treat.) With sweating and no aversion to cold, it is called Rou Ji (Soft Spasm); without sweating and with aversion to cold, it is called Gang Ji (Hard Spasm). Without sweating, Gegen Tang is used; with sweating, Guizhi Tang is used; both types of Ji are suitable for Xuming Tang. (Without sweating, Gegen Tang; with sweating, Guizhi Tang, respectively inducing sweating and releasing the muscle layer. Ji has Gang Ji and Rou Ji. Gang Ji has no sweating, Rou Ji has sweating, naturally suitable for Xuming Tang. Zhang Zhongjing stated: In Taiyang disease with fever, without sweating, and contrary aversion to cold, it is named Gang Ji; with sweating and no aversion to cold, it is named Rou Ji.) Leg cramps and teeth-grinding are all due to Yang heat; Chengqi Tang is suitable for purging and is most effective. (All the above are Heat syndromes, and Chengqi Tang should be used.) These are also named Yang Ji and Yin Ji; names differ but reality is the same, do not forget. (Ji sounds like 'chi', Jing reads 'ju ying' reverse, names differ but reality is the same.)
(Food Stagnation, Deficiency Disturbance, Cold Phlegm, Hongxiangjiao [Beriberi])
Food stagnation causing deficiency disturbance combined with phlegm, plus Hongxiangjiao symptoms resembling Shanghan (Cold Damage). Although the four diseases' presentations are said to be different, fever and aversion to cold are the same. (These four syndromes are not Shanghan, yet fever and aversion to cold are identical; they must be distinguished by pulse and syndrome.) Cold phlegm at Zhongwan causes chest fullness and oppression; the pulse is floating, spontaneous sweating occurs, and the body is difficult to keep dry. (This is a Phlegm syndrome. With phlegm, there is chest oppression, spontaneous sweating, and a floating pulse.) Food stagnation causes inevitable headache; lack of body pain indicates the presence of stagnation. A tight and full Qi Kou pulse indicates food injury; mental restlessness, rapid pulse, vomiting, and acid regurgitation. (This is Food Stagnation. With food stagnation, the body does not hurt, only vomiting/nausea and acid regurgitation occur; the Qi Kou pulse is tight and full, while other pulses are rapid. Zhu Gong stated: A tight and full Qi Kou pulse indicates food injury.) The pulse of Deficiency Disturbance is not tight or solid; one only feels heat and restlessness in the body and mind. No body pain, no headache; only Zhuye Tang is suitable for peace. (Sun Shang stated: Deficiency Disturbance resembles Shanghan, but after two or three days of illness, the pulse is not floating, there is no aversion to cold, no body pain, only heat without restlessness. Sweating must not be induced, as it will cause critical damage. If the pulse is not tight/solid, pain is not severe, only heat or lack of restlessness, it is not an Interior Excess syndrome, so purging must not be used, as it will cause critical damage. Only Zhuye Tang can be administered.) There is also Hongxiangjiao disease, where stool is hard and walking is difficult. Both calves are swollen and full or withered and thin. Do not view Hongxiangjiao as the same category as Shanghan. (This discusses Hongxiangjiao. Patients with Hongxiangjiao have hard stools, swollen and painful feet/knees, and either swollen/full or withered/thin calves. During onset, there is also fever and aversion to cold, vomiting and nausea, resembling Shanghan manifestations.)
