(Wu Kun's *Yi Fang Kao*) Treats all types of consumptive diseases (Lao Zhai) and stagnation, provided they have not been complicated by improper medication.

Danggui (Angelica sinensis), Ruxiang (Boswellia carterii, de-oiled), Moyao (Commiphora myrrha, de-oiled), Renshen (Panax ginseng) (each 1 qian), Machong (Blatta orientalis), Shizhi (Hirudo nipponica) (each 14 pieces), Dahuang (Rhei Radix et Rhizoma) (4 qian). Grind into fine powder, mix with refined honey to make pills the size of tung tree seeds. Take 100 pills each time. Administer at the hour of Wugeng (approx. 3-5 AM) using Bailao water (i.e., Ganlan water, prepared by stirring vigorously with a ladle one hundred times). Continue until foul matter is evacuated. Follow with a white rice porridge diet for ten days. (Another version includes Taoren 14 pieces.)

Song of Bailao Wan: Dahuang, Danggui, Renshen, Taoren, Ruxiang, Moyao; Machong and Shizhi disperse dry blood accumulation. For Lao Zhai and stagnation, take this formula; if not yet damaged by prior treatment, follow this path.

(Note: Bailao Wan was transmitted by Dr. Chen from Xuzhou, originating from Zhang Zhongjing's prescriptions, treating various consumptive diseases with stagnation that have not been mishandled. Upon careful examination, this formula merely tonifies both Qi and Blood, harmonizes Ying and Wei, and expels stasis; it bears no relation to the principle of "soothing the middle and tonifying deficiency." It is inferior to the Chongwan formula in *Jin Gui Yao Lue*. However, the use of Bailao water avoids aiding kidney pathogens, allowing the medicine to remain in the Middle Jiao (Spleen and Stomach), guiding out stasis from the collateral vessels of the Spleen and Stomach, thereby facilitating digestion and ensuring smooth circulation of Ying and Wei. This is also an excellent treatment for Dry Blood Lao.)

Treats Da Chang Yong (Intestinal Abscess). The symptoms include swelling and distension in the lower abdomen, pain upon pressure resembling Lin syndrome (dysuria), but urination remains normal, accompanied by fever, aversion to cold, and sweating. If the pulse is slow and tight, pus has not yet formed; purgation may be used, and blood may appear in the stool. If the pulse is surging and rapid, pus has already formed; purgation is contraindicated.

Dahuang (4 liang), Mudanpi (Moutan Cortex) (1 liang), Taoren (Persicae Semen) (50 pieces), Tian Guazi (Benincasa hispida seed) (0.5 sheng), Mangxiao (Natrii Sulfas) (3 he). Boil in 6 sheng of water until reduced to 1 sheng.

Song of Dahuang Mudan Tang: Dahuang Mudan Tang is a purgative formula; combined with Taoren, Guazi, and Mangxiao. Lower abdominal swelling and hardness cause pain on pressure; pain resembles Lin syndrome (due to heat pouring down from the Large Intestine). Urination is normal (the disease is not in the Small Intestine water passages, hence urination is normal). Skin is rough like fish scales (due to obstruction of Ying and Blood); right leg is flexed (at the onset of Large Intestine abscess, the right leg flexes and does not extend, whereas Small Intestine abscess causes left leg flexion; this distinguishes them). This formula can eliminate Large Intestine abscess. A deep and tight pulse indicates unformed pus; a surging and rapid pulse indicates abundant pus. When pus is unformed, purgation should be employed; when pus is formed, Painong San (Paired Orange Decoction class, see separate section) should be invited. (Large Intestine abscess arises in individuals who habitually consume rich wine and roasted meats, leading to damp-heat stagnation. Lung Qi fails to diffuse, descending to the head of the Large Intestine, causing Qi and Blood congestion. Since the pathology is below, it is treated by draining; thus, heavy doses of Dahuang and Mangxiao are used to open the intestinal knot, Taoren and Mudanpi to move failing blood, and Guazi to clear the Lung and moisten the intestines, as the Lung and Large Intestine are exterior-interior pairs. The prescription notes "blood will appear," referring to un-pusified blood being evacuated. If pus has formed and flesh is ruined, then...)
