Treats Taiyang disease (Taiyang syndrome) and warm diseases where sweating should have been induced but was not, leading to the internal accumulation of blood stasis; as well as cases where epistaxis (nosebleed) or hematemesis (vomiting blood) is incomplete, with residual blood remaining stagnant, causing a sallow complexion and black stools.

Xijiao (Rhinoceros Horn, 1 liang) Shengdihuang (Rehmanniae Radix Recens, 8 liang) Shaoyao (Paeoniae Radix Alba, 3 liang) Mudanpi (Moutan Cortex, 2 liang)

Grind the above ingredients into a coarse powder. Take 4 qian per dose, add 1.5 sheng of water, decoct until reduced to 0.7 sheng, then strain. For patients exhibiting mania (kuang), add Dahuang (Rhei Radix et Rhizoma, 2 liang) and Huangqin (Scutellariae Radix, 3 liang). If the patient's pulse is initially large but subsequently slow, the abdomen feels full though it is not distended, and the patient complains of fullness, this indicates an absence of heat; follow the original prescription without additions.

When a patient sweats profusely, staining clothes with bright red sweat, it is termed "sweating blood" (hanxue). This is generally caused by excessive joy injuring the Heart (Xin); joy causes qi to dissipate, and blood follows the qi in its movement. Women during the postpartum confinement period often present with this syndrome.

Treats postpartum women who, due to excessive joy, sweat profusely staining clothes red; as well as gao lin (cloudy urine resembling grease) and hematuria (blood in urine).

Caobai (Herba Siegesbeckiae, amount unspecified)

Crush and extract the juice, obtaining 2 sheng. Mix with 2 he of vinegar. Drink one cup on an empty stomach; or decoct thickly and drink. This method also treats dribbling hematuria.

When a patient passes blood from the rectum, the blood may be clear or turbid, fresh red or black, appearing before defecation, after defecation, or mixed with feces. This is caused by external or internal pathogenic factors injuring the body, causing blood to stagnate in the Stomach (Wei) and descend with the qi, representing a type of reckless bleeding; hence it is called "hematochezia" (bianxue).

Treats hematochezia where defecation precedes bleeding, termed "remote blood" (yuanxue). Also treats hematemesis and epistaxis.

Fulonggan (Draconis Os, 0.5 jin) Gancao (Glycyrrhizae Radix et Rhizoma, processed) Baizhu (Atractylodis Macrocephalae Rhizoma) Ejiao (Colla Corii Asini) Shengdihuang (Rehmanniae Radix, dried; *Qianjin Fang* suggests Ganjiang/Zingiberis Rhizoma) Huangqin (Scutellariae Radix) (each 3 liang)

Grind the above ingredients into a coarse powder. Take 5 qian per dose, add 1 sheng of water, decoct until reduced to 0.7 sheng, then strain. Take warm on an empty stomach. Another method includes adding 3 liang of Paofuzi (Aconiti Lateralis Radix Praeparata, processed).

Treats hematochezia where bleeding precedes defecation, termed "proximal blood" (jin xue).

Chixiaodou (Phaseoli Semen Rubrum, 5 liang, soaked until sprouted then dried; another method involves roasting until split) Danggui (Angelicae Sinensis Radix, 1 liang)

Grind the above ingredients into a fine powder. Administer one fangcunbi (a measure equivalent to a square inch spoonful) with jiangshui (fermented grain water), three to four times daily.

When wind pathogens remain in the skin and interstices (couli), invading the intestines and stomach due to deficiency, the wind agitates the blood, resulting in the passage of clear blood or blood stasis, with uncontrolled diarrhea, termed "wind li" (fengli). Ancient formulas classified this as gu li (gu dysentery), which is incorrect.
