(Sweating excessively leads to the loss of Yang Qi, depletion of Body Fluids, and failure of the sinews and muscles to receive nourishment; thus, there is trembling of the sinews [Jin Ti] and twitching of the muscles [Rou Yu].)
The pulse is faint and weak, with sweating and aversion to wind. If Da Qing Long Tang (Major Green Dragon Decoction) is mistakenly administered, it will result in cold extremities [Jue Ni] and tremors of sinews with twitching of muscles [Jin Ti Rou Yu]. (Treat with Zhen Wu Tang [True Warrior Decoction]). In Taiyang disease [Taiyang Bing], if fever persists after sweating, accompanied by dizziness [Xuan Yun] and bodily tremulousness [Zhen Dong], (treat with Zhen Wu Tang [True Warrior Decoction] or Ren Shen Yang Rong Tang [Ginseng Nourishing Nutrient Decoction]). After vomiting or purging, if sweating is induced again, it causes empty irritability [Xu Fan], a faint pulse, epigastric fullness [Xin Pi], hypochondriac pain, rebellious Qi causing dizziness and vertigo [Xuan Mao], bodily tremulousness [Dong Ti], which over time may develop into flaccidity syndrome [Wei Zheng]. (Treat with Gui Zhi Ling Zhu Gan Cao Tang [Cinnamon Twig, Poria, Atractodes, and Licorice Decoction]).
Generally speaking, this type of syndrome arises from improper sweating in seven or eight out of ten cases. If not caused by sweating, but due to inherent Blood deficiency where pathogenic heat contends with Blood, this syndrome also appears. There are also cases where no sweating was induced, yet after seven or eight days, there is trembling of sinews without muscle twitching, tidal fever [Chao Re], constipation [Da Bian Bi], dysuria [Xiao Bian Se], and hardness and pain around the umbilicus; this is dry stool [Zao Shi]. It should be purged with Da Chai Hu Tang (Major Bupleurum Decoction). One is deficiency, the other is excess; the treatment methods are vastly different. Clinicians must examine carefully.
(Chou Chu [convulsions] refers to the urgency and contraction of sinews and vessels; Chi Zong [clonic spasms] refers to the relaxation and extension of sinews and vessels. Alternating extension and contraction cause traction and jerking of the hands and feet because Wind governs movement and shaking.)
After sweating or purging, convulsions appear after a long duration. (This is Wind generated by extreme deficiency; treat with modified Xiao Xu Ming Tang [Minor Continuation of Brightness Decoction]). Convulsions appearing not due to sweating or purging. (Treat with Qiang Huo, Fang Feng, Huang Qin, Huang Lian, Tian Ma combined with Si Wu Tang [Four Substances Decoction] etc.). Sweating followed by exposure to wind, with unsmooth flow of sweat, leading to jerking of hands and feet. (Treat with Niu Bang Gen San [Arctium Root Powder]). In Wind-Warmth disease [Feng Wen Bing], if forced by fire therapy, resulting in a slightly yellow complexion and convulsions, (treat with Wei Rui Tang [Polygonatum Decoction]).
The Liver is the organ of Wind and Wood, governing the sinews. When Wind and Fire contend, convulsions are common. One should soothe the Liver and descend Fire, assisted by harmonizing the Blood. If Phlegm is present, Er Chen Tang [Two Old Decoction] with Zhu Li [Bamboo Sap] is primary. If it belongs to deficiency, Bu Zhong Yi Qi Tang [Tonify the Middle and Augment the Qi Decoction] takes precedence. When applying Xiao Xu Ming Tang [Minor Continuation of Brightness Decoction], remove Ma Huang [Ephedrae Herba] if there is sweating, and remove Huang Qin [Scutellariae Radix] if there is no sweating; this is the standard method. If Dai Yan [fixed upward gaze] occurs, with sweat like pearls that coagulate and do not flow, this indicates the exhaustion of the Taiyang channel [Taiyang Jue Ye]. Furthermore, if the four limbs tremble continuously [HT HT - representing tremors], moving incessantly, resembling convulsions but lacking strength for strong jerking, this indicates the exhaustion of the Liver [Gan Jue Ye]. Excessive sweating and purging leading to these changes over a long period are mostly incurable.
