Dry blood refers to blood that is stagnant and dried. Stagnation generates heat, which internally damages the Liver and Lung, causing fever and coughing that worsen day by day; if untreated, it develops into consumptive disease (Xulao). This corresponds to what is stated in *Jinkui Yaolue*: "The meridians, collaterals, Ying, and Wei Qi are damaged; there is dry blood within, the skin is rough like fish scales or armor plates, and the area around both eyes is dark."

Wang Nianxi stated: Fever arising from deficiency-consumption is invariably caused by blood stasis, and blood stasis invariably arises from internal injury. Any slight disharmony in one's daily routine or diet can cause injury. The accumulated stagnant blood is firmly fixed and difficult to dislodge; new blood cannot circulate throughout the body. As the accumulation increases day by day, how can the person retain vitality? Zhang Zhongjing employed extraordinary methods: using moistening agents to soften the dry blood, and using creeping creatures that feed on blood to move the dead blood. Once the dead blood is removed, the root of the disease is eradicated, allowing for subsequent tonification and nourishment. Chen Dafu's Bailao Wan can be used in conjunction with this formula.

Yu Jiayan stated: This is an excellent treatment for the dry-blood consumption commonly known in secular practice. When blood is knotted internally, the pulses in the hands and feet will necessarily be discordant; this formula is appropriate. However, it must be taken concurrently with a major tonic such as Qiongyu Gao (Jade Dew Paste). Note: "Discordant" means not harmonious. This is due to the obstruction of the vessels caused by blood knotting.

Chen Dafu Bailao Wan (Master Chen's Hundred Consumptions Pill)
Indications: Suitable for all types of consumptive diseases with stagnation, and for conditions deteriorated due to improper medication.
Ingredients: Jinwen Dahuang (Rhei Radix et Rhizoma, peeled and core removed, 4 qian), Ruxiang (Boswelliae Resina), Moyao (Commiphorae Resina), Danggui (Angelicae Sinensis Radix, each 1 qian), Renshen (Ginseng Radix, 2 qian), Taoren (Persicae Semen, peeled and germ removed, ground separately into a paste), Mengchong (Asii Mantis Ootheca), Shuizhi (Hirudo, each 14 pieces, stir-fried).
Preparation and Administration: Grind the above ingredients into an extremely fine powder. Mix with refined honey to form pills the size of tung tree seeds. Prepare enough for a single dose, approximately 100 pills. Administer at the fifth watch (early morning) with Bailao Water, until foul matter is expelled. Follow with white porridge.
Note: The text states "prepare as one dose"; here, "dose" should be interpreted as "quantity/formulation." Quantity refers to dosage. The size and number of pills are determined according to the severity of the illness. The phrase "until foul matter is expelled" indicates that the entire amount is not necessarily consumed in one sitting.
