[Xue Ji] Tang Shi stated: Cold diarrhea is caused by deficiency-cold of the Spleen and Stomach, leading to the failure to digest water and grain, resulting in diarrhea. Qian Zhongyang stated: When infants cannot take milk, pass brown stools, and have cold limbs, it indicates a lack of Yang Qi; Yi Huang San (Spleen) should be used with modifications. If the stool is clear and white, and there is no thirst or irritability, it is cold accumulation diarrhea, for which Li Zhong Tang (Vomiting and Diarrhea) is the primary formula. If caused by inhaling wind-cold through the mouth and nose, or by consuming raw and cold foods that damage the Spleen and Stomach, one should first administer Li Zhong Tang, followed by Yi Gong San. If the Fire of the Gate of Vitality (Mingmen) is deficient and fails to warm and steam the Qi of the Middle Jiao, resulting in Spleen-Stomach deficiency-cold, use Yi Huang San and Ba Wei Wan (Kidney). For Spleen-Stomach weakness, use Wu Wei Yi Gong San (Vomiting and Diarrhea). For sinking of Spleen Qi, use Bu Zhong Yi Qi Tang (Deficiency Heat). For deficiency-cold of Spleen Qi, use Ren Shen Li Zhong Tang. For Cold Water insulting Earth, use Yi Huang San. For Liver Wood overacting on Spleen, use Si Jun Chai Hu San. If both hands and feet are cold, add Mu Xiang and Gan Jiang. Practitioners must examine carefully. The Bai Wen states: For cold accumulation diarrhea, Mei Shi Zi Wan is extremely effective; adding Ren Shen San (Vomiting) and Li Zhong Tang (Vomiting and Diarrhea) with modifications is also excellent; adding Rou Dou Kou can stop diarrhea; Lai Fu Dan (Major Summerheat) and Bu Huan Jin Zheng Qi San (Vomiting and Diarrhea) are all suitable; Guan Yin San (Vomiting and Diarrhea) and Yin Bai San, when modified, are mild and harmonious formulas.
