Deputy Marshal of the Southern Expedition, Da Teimur, was sixty-eight years old. In the autumn of the Wuwu year, during the southern expedition, I accompanied him. When passing ten li from Yangzhou, in the second month of winter (Zhongdong), he suffered from diarrhea with undigested food in the stool, cold pain in the umbilical and abdominal regions, and coldness in the feet. Scratching his feet with hands failed to elicit any sensation of pain or itch. Burning stones to warm them also failed to produce warmth. Upon diagnosis, his pulse was deep, fine, and faint. Reflecting on the etiology: due to advanced age and weak qi, entering enemy territory, heavy military duties, exposure to cold morning and evening, irregular diet, excessive consumption of milk and cheese, and dwelling in low-lying damp areas, yang qi failed to secure the exterior. Consequently, clear dampness invaded the deficiency, causing disease to arise from below, resulting in cold and reversal in the feet. The *Neijing* states: "Contracting cold leads to disease; mild cases manifest as cough, severe cases as diarrhea and pain." This is a disease caused by the combination of cold and dampness. The treatment principle should urgently dispel cold-damp pathogens and vigorously tonify yang. Only moxibustion can cure this condition. First, apply large moxa cones at Qihai (CV6) for one hundred burns to tonify lower jiao yang deficiency. Second, moxa Zusanli (ST36) bilaterally, thirty-seven burns each, to treat cold and reversal in the feet, and to guide yang qi downward. Third, moxa Sanyinjiao (SP6) bilaterally to dissipate cold-damp pathogens affecting the feet. Thus, the prescription was formulated as follows: For excess cold, treat with acrid-hot methods. For external dampness, level with bitter-hot methods. Use bitter flavors to disperse. Fuzi (Prepared Aconiti Lateralis Radix), extremely acrid and hot, assists yang and retreats yin, warms meridians and disperses cold, thus serving as the Sovereign herb. Ganjiang (Zingiberis Rhizoma) and Guigui (Cinnamomi Cortex), extremely hot, acrid, and sweet, also dispel cold and dampness. Baizhu (Atractylodis Macrocephalae Rhizoma) and Banxia (Pinelliae Rhizoma), bitter, acrid, and warm, dry spleen dampness, thus serving as Ministers. Renshen (Ginseng Radix), Caodoukou (Alpiniae Katsumadai Semen), and Zhigancao (Glycyrrhizae Radix et Rhizoma Preparata), sweet, acrid, and extremely warm, warm the middle and benefit qi. Shengjiang (Zingiberis Rhizoma Recens), extremely acrid and warm, disperses clear-damp pathogens. Congbai (Allii Fistulosi Bulbus), acrid and warm, unblocks upper jiao yang qi, thus serving as Assistants. It is stated: "Tonifying and treating the lower requires urgent preparation; urgency implies strong flavor and potency." Therefore, a large dose was prepared and administered. After several doses, diarrhea ceased, pain decreased, and feet gradually warmed. With dietary regulation, recovery occurred within ten days. The following autumn, passing through Xiangyang, continuous rain persisted for over ten days, and previous symptoms recurred. Moxibustion was repeated according to the previous method, adding Yangfu (GB38), thirty-seven burns per acupoint. The previous herbal medicine was administered again, resulting in excellent recovery after several doses.
