Discourse states: The *Neijing* (Inner Canon) mentions that the true qi of the zang organs connects to the Heart, and the qi of the blood vessels flows accordingly. It also states that the Liver stores blood, and when a person lies down, blood returns to the Liver. Generally, although blood is stored in the Liver, it is propelled by the Heart. If both the Liver and Heart are injured by pathogenic factors, blood will exit along with sweat from the body surface.

To treat blood sweating caused by injury to the Liver and Heart by pathogens, use Renshen Tang (Ginseng Decoction).
Renshen (Ginseng Radix et Rhizoma), Guizhi (Cinnamon Twig, removed coarse bark), Gancao (Licorice Root, roasted and chopped), Baishao (White Peony Root), Chishao (Red Peony Root) (each 1 liang), Huangqin (Scutellaria Root, removed black heart), Xiong (Ligusticum Rhizome), Danggui (Angelica Sinensis Root).
The above nine ingredients are coarsely pounded and sifted. Each dose consists of 7 qianbi, boiled in one dan of water until reduced to 0.7 dan. Strain and take warm, at any time.

To treat blood sweating exiting from the skin and interstices, use Shenbai San (Divine White Powder).
Renzhongbai (Calcinata Aluminis).
One ingredient, quantity unspecified. Scrape onto a new tile and dry over fire, then grind into an extremely fine powder. Each dose is 2 qianbi, mixed with a small amount of Shexiang (Musk) and taken with warm wine.

To treat blood sweating, use Rusheng San (Like-Sage Powder).
Yuliren (Prunus Armeniaca Seed, removed peel and tip).
One ingredient, ground finely. Each dose is 1 qianbi, taken with juice from Goose Pear (Pyrus ussuriensis Maxim.).

To treat blood sweating and continuous nosebleed, use Chuibi San (Blowing Nose Powder).
Renzhongbai (Calcinata Aluminis).
One ingredient, baked on a tile until dry, ground into a fine powder. Apply a small amount into the nose each time; recovery is immediate.

To treat hematemesis or blood sweating and hematuria, use Zhuru Tang (Bamboo Shavings Decoction).
Dan Zhuru (Bamboo Shavings), Renshen (Ginseng Radix et Rhizoma), Shaoyao (Peony Root), Jiegeng (Platycodon Root, chopped and stir-fried), Sheng Gan Dihuang (Rehmanniae Radix Preparata, dried and roasted), Danggui (Angelica Sinensis Root, sliced and roasted), Gancao (Licorice Root, roasted and chopped), Guizhi (Cinnamon Twig, removed coarse bark), Xiong (Ligusticum Rhizome) (each 1 liang).
The above nine ingredients are coarsely pounded and sifted. Each dose is 5 qianbi, boiled in 1.5 dan of water until reduced to 1 dan. Strain and take warm, at any time.

Discourse states: The *Neijing* says that if Spleen heat transfers to the Liver, it results in palpitations and nosebleeds. This is because the Spleen belongs to Earth and the Liver to Wood; Earth naturally fears Wood. Now, if Spleen heat transfers to the Liver, Earth qi becomes excessive, and heat attacks Wood. The Liver stores blood, and its spirit is Hun (Ethereal Soul). When deficient heat prevails, it causes palpitations and nosebleeds. Those occurring from Spring to Summer are called Taiyang nosebleeds; those from Autumn to Winter are called Yangming nosebleeds. Chao Yuanfang stated that a faint and cunkou pulse indicates nosebleed; a faint cunkou pulse with aversion to cold indicates nosebleed; a faint cunkou pulse, choppy chi pulse, fever, and weak pulse indicate blood deficiency and必然 lead to Jue (cold extremities). The patient may have slight vomiting. Jue should involve dizziness; if there is no dizziness but instead headache, the pain indicates excess. Lower deficiency and upper excess inevitably lead to nosebleeds. All such cases relate to these pulses. Sun Simiao said that a white nasal tip indicates loss of blood; if slightly red out of season, death ensues. Patients with pale complexions all suffer from blood loss. In epidemic diseases, nosebleeds should not be forcibly stopped. If bleeding exceeds one or two sheng, causing concern for excessive loss, Longgu (Fossilized Bones) powder can be blown into the nose. All such cases relate to these signs. As for bleeding from all nine orifices, it is called Da Nu (Major Nosebleed). If Gallbladder heat transfers to the Brain, excessive heat causes overflow of Yang collaterals. Overflow of Yang collaterals leads to Nu blood and blood sweating, collectively termed Nu. Treatments vary according to specific formulas and discourses.
