Hunger without desire to eat, vomiting of roundworms (Ascaris lumbricoides), and cold extremities constitute the fundamental syndrome of the Jueyin channel. Hunger without ability to eat after purgation belongs to the Yangming disease. In Yangming disease, one may experience mental restlessness and oppression, extreme vexation in the epigastrium, and sweating on the head; this indicates heat in the stomach, for which Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction) should be used to induce emesis. In Jueyin disease, if the pulse is faint or not faint but tight, accompanied by increased vexation, this is not due to cold deficiency pathogens, but rather cold excess pathogens lodged in the chest; Gengdi San (Melon Seed Powder) should be used to induce emesis.
The Taiyin channel does not present with cold extremities, but rather naturally warm hands and feet. The Shaoyin channel presents with cold jue (cold extremities) but not heat jue. The Jueyin channel presents with both cold and heat jue. Cold jue involves only coldness without heat; heat jue originates from heat leading to cold extremities, and from cold extremities transforming into heat, with heat and jue reciprocally causing each other without cessation. One must distinguish the depth and nature of yin and yang, treating with Danggui Sini Tang (Angelica Sinensis and Cinnamon Twig Decoction), Chengqi Tang (Purgative Decoctions), etc., as appropriate.
Fullness in the lower abdomen with pain upon palpation. If the limbs are cold and urine is clear and white, this is cold binding in the Bladder; Danggui Sini Tang plus Wuzhuyu and Shengjiang (Evodia and Fresh Ginger) should be used. If the limbs are not cold and urination is free, this is blood accumulation in the Bladder; Taoren Chengqi Tang (Peach Kernel and Rhubarb Purgative Decoction) should be used. If urination is difficult, this is water accumulation in the Bladder; Wuling San (Five-Ingredient Powder with Poria) should be used. If both defecation and urination are obstructed, this is water-heat accumulation; Bazen San (Eight-Ingredient Powder) should be used.
Mental confusion results from extreme heat in the Stomach channel assaulting the Heart. Heat entering the yang aspect causes mania and mental confusion. For mania with exterior excess and no sweating, Sanhuang Shigao Tang (Three-Yellow and Gypsum Decoction) is indicated. For interior excess with constipation, the three Chengqi Tangs (Purgative Decoctions) are indicated. Without exterior or interior syndromes, but with extreme interior heat, Baihu Tang (White Tiger Decoction) is indicated. Sunyang blood accumulation causing mania presents with hardness and pain in the lower abdomen and free urination; if urination is difficult, it is water-heat accumulation, not blood accumulation. Yangming blood accumulation causing manic-like behavior presents with forgetfulness and black stools; if stools are not black, it is extreme heat, not blood accumulation. For mild blood accumulation syndromes, Taoren Chengqi Tang is used; for severe cases, Didang Tang (Definite Attack Decoction) is used, selecting according to severity. However, some cases of mania occur in individuals with excessive yang and deficient yin; at the time when sweat is about to emerge to resolve the disease, sudden mania may occur, followed by profuse sweating and recovery. This pattern must be recognized and requires no medication.
