Food stagnation that fails to digest requires purgation. The Cun (inch) position pulse is floating and large, while the Chi (cubit) position pulse is faint. (If a patient has retained food, how can it be distinguished? The Master said: The Cun position pulse is floating and large, but feels rough upon deep pressure; the Chi position pulse is also faint and rough. Purgation should be applied at this time, with Chengqi Tang as the primary formula.) Yangming syndrome with stagnant heat causing jaundice. (Zhang Zhongjing stated: When Yangming stagnant heat is trapped in the interior, the body will inevitably turn yellow. Yinchen Hao Tang is appropriate for treatment.) For delirium, Chaihu Tang is most suitable. (The *Jin Gui Yao Lue* states: If there is sweating accompanied by delirium, dry feces are present in the stomach; this is due to wind pathogen. Purging should only be performed after the disease has passed through its stages. Da Chengqi Tang or Da Chaihu Tang are appropriate.) For Jie Xiong (chest binding), Da Xianxiong Wan is indicated. For blood stasis, Didang Tang must not be delayed. (For Jie Xiong, Da Xianxiong Tang is used for purging; for blood stasis, Didang Wan is used for purging.) For hard stool, only Chengqi Tang should be used. For Pi Qi (fullness obstruction), Xiexin Tang should be used without hesitation. (For hard stool, Chengqi Tang is used for purging; for Pi Qi caused by deficiency, Xiexin Tang is used for regulation.) If the pulse indicates deficient Yang, purging will lead to fullness obstruction. (From here onwards, conditions where purging is contraindicated are discussed. The *Jin Gui Yao Lue* states: One with deficient Yang cannot be purged; doing so results in epigastric fullness and hardness.) If accompanied by a deficient and thin pulse, purging is even more difficult. (Zhang Zhongjing stated: A faint pulse prohibits emesis; a deficient and thin pulse prohibits purging.) For Jie Xiong with a floating and large pulse, purging leads to death. (The *Jin Gui Yao Lue* states: In Jie Xiong syndrome, if the pulse is floating and large, purging is contraindicated; doing so leads to death.) For Sini (cold extremities) syndrome, purging endangers life. (The *Jin Gui Yao Lue* states: Those with cold extremities cannot be purged; doing so leads to death, and the same applies to those with constitutional deficiency.) Chills indicate that exterior syndrome still exists. (The presence of chills indicates an exterior syndrome, which prohibits purging.) Vomiting still implies stomach Qi deficiency. (Zhang Zhongjing stated: Patients suffering from vomiting cannot be purged.) Failure to pass flatus必然 leads to loose stools. (Zhang Zhongjing stated: In Yangming syndrome, if there is no bowel movement for six or seven days, one may suspect dry feces. To determine this, Xiao Chengqi Tang may be given. If flatus passes in the abdomen, dry feces are present, and attack/purging is permissible. If flatus does not pass, the stool head may be hard, but the remainder will likely be loose; purging is contraindicated.) In Yangming syndrome with spontaneous sweating, purging is difficult to effect. (In Yangming syndrome with spontaneous sweating and free urination, this indicates depletion of body fluids internally. Although the stool is hard, it cannot be attacked/purged; Mi Jian Dao (honey suppository) is appropriate.) Throat blockage is especially contraindicated for purging. (The *Yu Han Jing* states: Throat blockage prohibits purging; doing so leads to upper deficiency and lower excess, with a desire to curl up when lying down and acute pain.) Fuyang floating and rapid pulse indicates spleen deficiency. (Zhang Zhongjing stated: The Fuyang pulse is floating and rapid. Floating injures the Stomach; rapidity disturbs the Spleen. This is not the original disease, but the result of the physician's erroneous purging.) If there is moving Qi on the left, right, upper, or lower, careful harmonization and treatment are required. (Zhang Zhongjing stated: Moving Qi on the right, purging depletes internal fluids, causing dry throat and nose, dizziness, and palpitations. Moving Qi on the left, purging causes abdominal fullness and急促 breathing. Moving Qi in the upper region, purging causes hot palms and irritability. Moving Qi in the lower region, purging causes abdominal fullness and sudden dizziness upon standing.)
