Sweating during sleep (Dao Han) belongs to Blood Deficiency and Yin Deficiency. In children, it does not require treatment; fresh ginger is contraindicated. Li Dongyuan has a prescription, using Danggui Liu Huang Tang (Cinnamon Twig and Six Yellow Decoction), which is very effective.
However, the medicinal nature is cold; for those with deficiency constitution, only Huangqi Liuyi Tang (Astragalus Six-to-One Decoction) should be used. Sweating during sleep accompanied by fever is due to Yin Deficiency; use Siwu Tang (Four Substances Decoction) plus Huangbai (Phellodendron Bark); if Qi Deficiency is also present, add Renshen (Ginseng), Huangqi (Astragalus Root), and Baizhu (Atractylodes Macrocephala Rhizome).
Dai Yun said: Sweating during sleep refers to sweating while sleeping; without sleep, there is no sweating. When in deep sleep, sweat flows quietly; upon waking, it stops. It is not like spontaneous sweating (Zi Han) that occurs naturally. For miscellaneous diseases involving sweating during sleep, the cause is attributed to Yang Deficiency, which differs from sweating during sleep in Shanghan (Cold Damage); it is also caused by Heart Deficiency. One should astringe Heart Qi and nourish Kidney Water, so that Yin and Yang harmonize, and Fire and Water ascend and descend normally, whereupon the sweating will cease on its own.
Attached Formulas
Danggui Liu Huang Tang (Cinnamon Twig and Six Yellow Decoction) A miraculous agent for treating sweating during sleep.
Danggui (Angelica Sinensis Radix), Sheng Dihuang (Rehmanniae Radix Praeparata cum Melle - Raw Rehmannia), Shu Dihuang (Rehmanniae Radix Praeparata), Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Huangbai (Phellodendri Cortex), Huangqi (Astragali Radix - doubled dosage).
Take five qian of the above, decoct in water and take orally. Alternatively, add Gancao (Glycyrrhizae Radix et Rhizoma), Mahuanggen (Ephedrae Herba - root part), and Chao Zhizi (Gardeniae Fructus Praeparatus), removing Danggui.
Huangqi Liuyi Tang (Astragalus Six-to-One Decoction)
Huangqi (Astragali Radix) (six liang), Gancao (Glycyrrhizae Radix et Rhizoma) (one liang).
The above are each honey-fried more than ten times to remove fire toxicity. Take one liang per dose, decoct in water.
Another Prescription
Baizhu (Atractylodis Macrocephalae Rhizoma) four liang, divided into four parts. One part is stir-fried together with Huangqi (Astragali Radix), one part with Shihu (Dendrobii Caulis), one part with Mumli (Ostreae Concha), and one part with Mai Fu (Triticum Vulgare Bran).
Each is lightly stir-fried until yellow, then the other ingredients are removed, leaving only Baizhu (Atractylodis Macrocephalae Rhizoma) to be ground into fine powder. Take three qian per dose, mixed with millet soup. Consuming the entire four liang yields excellent results.
Zhengqi Tang (Righteous Qi Decoction) Treats sweating during sleep.
Huangbai (Phellodendri Cortex) (fried), Zhimu (Anemarrhenae Rhizoma) (fried, each one and a half qian), Gancao (Glycyrrhizae Radix et Rhizoma) (honey-fried, five fen).
Prepare as one dose, decoct in water. Take hot before meals.
Maijian San (Wheat Decoction Powder) Treats disharmony of Ying and Wei (Nutritive and Defensive levels), frequent sweating during sleep at night, vexation and pain in the four limbs, and emaciation of muscles.
Zhimu (Anemarrhenae Rhizoma), Shigao (Gypsum Fibrosum), Gancao (Glycyrrhizae Radix et Rhizoma) (honey-fried), Huashi (Talcum), Digupi (Lycii Cortex), Chishao (Paeoniae Radix Rubra), Tingli (Descurainiae Semen seu Lepidii Semen), Xingren (Armeniacae Semen Amarum) (fried, skin and tip removed), Renshen (Ginseng Radix), Baifuling (Poria), Mahuanggen (Ephedrae Herba - root part).
Grind all into powder. Take one qian per dose, mixed with floating wheat soup.
Another Prescription Treats cases where there is no sweating elsewhere on the body, but only sweating in a patch over the heart region. Excessive thinking leads to more sweating; the pathology lies in the misuse of the Heart. One should nourish Heart Blood, decoct Aiye (Artemisiae Argyi Folium), and mix with one qian of Fuling (Poria) powder to take orally. This is called "Heart Sweating" (Xin Han). Additionally, take the second leaf of Qing Sang (Morus Alba) tree, bake dry, grind into powder, and take with rice drink on an empty stomach; this is most effective for stopping sweating during sleep.
