(Nichao Yuanfang stated: The Liver stores blood, and the fluid of the Heart is sweat. This means that when both the Heart and Liver are injured by pathogenic factors, blood emerges from the skin pores; this condition is named Ji Nu (Cutaneous Purpura).)
Huangjianzhong Tang (Yellow Middle-Building Decoction) treats sweating of blood that stains clothes, severe cases resembling dyeing on raw cloth. This is caused by excessive joy injuring the Heart; joy causes Qi to dissipate, and blood follows the movement of Qi.
It is suitable for those with weak constitutions. (Formula see Section on Deficiency and Damage.)
Miaoxiang San (Wonderful Fragrance Powder) treats sweating of blood. (Formula see above.) Another method uses burnt fetal hair ash applied externally to stop bleeding.
(Refer to this in conjunction with the section on Blood Lin Syndrome. It is caused by injury due to sexual excess, leading to Yin deficiency with hyperactive fire, causing Ying Blood to move recklessly; this condition is named Jing Nu (Shin Purpura). Painful urination is Blood Lin Syndrome; painless urination is Ni Xue (Blood in Urine). Those fond of sexual activity often have a deficiency pattern.)
Fahui San (Hair Ash Powder) treats hematuria in men, urinary retention due to bladder displacement (Zhuan Pao) in women, and Blood Lin Syndrome. (Formula see Section on Lin Syndrome.)
Jiu Zheng Huanglian Wan (Wine-Steamed Coptis Pill) treats hematuria. (Formula see under the section on Vomiting Blood.)
Another prescription treats blood appearing after urination. Burn dried persimmon until carbonized but retaining its nature, grind into powder, and take with rice water.
Another prescription uses juice of fresh Rehmanniae Radix (Sheng Dihuang), mixed with a small amount of ginger juice, and taken orally.
Another prescription uses juice of Dilucao (Plantago asiatica L. or similar herb), extracted by crushing, and taken orally.
Chensha Wuling San (Cinnabar Five-Ingredient Powder with Poria) is taken mixed with decoction of Jiedixin (Centella asiatica / Herb of Centella). (Formula see Section on Cold Damage.)
Zhu Danxi said: This pattern belongs to Heat. Use stir-fried Gardeniae Fructus (Shanzhi) decocted in water and taken orally. Alternatively, use Xiao Su (likely referring to a specific preparation or herb contextually linked to clearing heat/resolving phlegm, though WHO standard may vary, here kept as Xiao Su) and Hupo (Amber); these greatly treat Lower Jiao Blood Lin Syndrome.
Siwu Tang (Four Substances Decoction) combined with Niuxi (Achyranthis Bidentatae Radix), Shengdihuang (Rehmanniae Radix Recens), Xiao Su, Huashi (Talcum), Tongcao (Tetrapanacis Medulla), Puhuang (Typhae Pollen), Danyezhu Ye (Bambusae Folium), Ou Jie (Nelumbinis Node), Chuan Gui (Angelicae Sinensis Radix), Chao Zhizi (Stir-fried Gardeniae Fructus), and Zhi Gancao (Prepared Licorice Root) is decocted and taken orally.
Wuling San (Five-Ingredient Powder with Poria) combined with Siwu Tang (Four Substances Decoction) is decocted and taken orally. Alternatively, taken mixed with rice water. Mixing with Brown Ash or Hair Ash is particularly excellent. For pain in the urethra, use Gancao Shao (Licorice Root Tip), and add slightly Diyü (Sanguisorbae Radix), Chenpi (Citri Reticulatae Pericarpium), Baizhi (Angelicae Dahuricae Radix), and Brown Ash to the blood-stopping herbs.
For purpuric pain, use Chao Puhuang (Stir-fried Typhae Pollen), Pogostemonis Herba (Poguozhi), and Gu Duanshi (Ancient Smelted Lime) ground into powder and taken orally. Or use Puhuang alone, mixed with Scallion Juice, or add Wen Ge Mo Hui (Clam Shell Ash) to the decoction. Generally, hematuria indicates Qi stagnation in the Small Intestine and Bladder. Cheqianzi (Plantaginis Semen) ground into powder, taken with decoction of Cheqiancao (Plantaginis Herba) two qian is effective.
For those with Yin deficiency due to excessive sexual activity, use Lurong Wan (Deer Antler Pill) and Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia). (Both see Section on Deficiency and Damage.)
Zhusha Miaoxiang San (Cinnabar Wonderful Fragrance Powder) and Yuxie Gao (Jade Dust Ointment/Paste) are important medicines.
Yuxie Gao (Jade Dust Paste) treats persistent hematuria. Long-standing cases belong to deficiency; this medicine is suitable.
Renshen (Ginseng Radix) and Huangqi (Astragali Radix) (equal parts, ground into powder). Cut large radish into slices about one finger thick, four to five slices. Soak briefly in honey, dip again in honey, bake dry, then grind into powder. Total approximately two liang. Take together with Ginseng and Astragalus powder using salt water.
Siwu Xuanming Yin (Four Substances Xuanming Drink) treats persistent hematuria, requiring one to two bowls at a time.
Decoct Siwu Tang (Four Substances Decoction) with Cheqianzi (Plantaginis Semen) and Mutong (Akebiae Caulis). Mix in Xuanmingfen (Mirabilite) two to three qian. Take on an empty stomach; one dose stops it. Afterwards, regulate with Bazhen Tang (Eight-Treasure Decoction).
Another prescription treats persistent hematuria. Decoct Bazhen Tang (Eight-Treasure Decoction), add Xuanmingfen (Mirabilite), and mix with two cups of pickled radish juice. Take before meals to stop bleeding.
Pediatric Hematuria: Use Gancao Fen (Licorice Powder) and Shengma (Cimicifugae Rhizoma) decocted to mix with Zhensha (Cinnabar) and Yi Yuan San (Benefit Origin Powder); extremely effective.
Small Intestine Bleeding Section: Use Danggui (Angelicae Sinensis Radix) and Baizhi (Angelicae Dahuricae Radix) ground into powder (two qian), taken with decoction of Danshidouchi (Fermented Soybean).
