《千金方》言∶凡方中用鸡子者，皆取先破者用之，它皆无力。又言∶凡天下
极冷，无过藻菜，但有患热肿毒丹等，取渠中藻菜，细切熟捣，敷丹上，浓三分，
干即易之。予谓不可以此涂，若毒在表，犹可措手，若抑之，则外不得泄，势必入
里，必先服托里药，方可施此。

《千金方》说：凡是方剂中使用鸡蛋的，都要选取先破开的鸡蛋使用，其他的都没有效力。又说：天下极冷的东西，没有超过藻菜的，如果有患热肿、毒丹等病症，取渠道中的藻菜，细细切碎煮熟后捣烂，敷在丹毒上，厚度约为三分，干了就更换。我认为不能这样涂抹，如果毒邪在体表，还可以处理；如果强行压制，则毒邪外不得宣泄，势必内陷入里，必须先服用托里透脓的药物，才可以施用这种方法。
Crush *Portulaca oleracea* (Purslane) with a mortar and pestle, drink the juice, and apply the dregs to the affected area. Additionally, apply raw sesame oil to the lesion. Alternatively, apply thickly boiled soybean juice to the area.
The *Yingru Fang* (Infant and Toddler Formulas) prescribes an untreatable formula for Dan entering the abdomen and spreading down to the scrotum:
*Ephedrae Herba* (Mahuang, 麻黄) (stir-fried), *Cimicifugae Rhizoma* (Shengma, 升麻) (each 3 fen), *Natrii Sulfas* (Xiaoshi, 硝石) (4 fen).
Grind the above into powder. Administer one fangcun bi (a measure of volume) with well water, three times daily. Another version adds *Rhei Radix et Rhizoma* (Dahuang, 大黄) by half a fen.
The *Liu Family Secret* provides a formula for Zoumatai (Running Horse Fetus) presenting as redness and swelling; if the pathogen enters the heart and abdomen, it is incurable:
Fresh *Sophorae Tonkinensis Folium* (Huaiye, 槐叶) (one handful), fresh *Trichosanthis Fructus* (Gualou, 栝蒌) (peeled, pounded together with Huaiye), powder of *Phaseoli Semen Rubrum* (Chidou, 赤豆) and *Vigna radiata* (Baidou, 白豆) (each 3 fen).
Mix evenly and apply to the affected area; the effect is miraculous.
Pound bamboo to extract juice, using one sheng (approx. 200ml) as a single dose; only one or two doses are needed for efficacy.
Pound Chinese chives (*Allium tuberosum*), add some salt and sesame oil, rub with hands until warm, and wipe over the Dan lesion; it heals immediately.
Treats all types of Dan liu (Dan tumors).
Grind *Natrii Sulfas* (Tuxiao, 土硝) into powder, mix with ginger juice and vinegar, and apply; apply three to four times daily. (Tuxiao refers to the earthen burrow of dung beetles or the nest of white grubs.) Five *Ricini Semen* (Bimazi, 蓖麻子), remove shells and grind finely, add one qian of *Triticum aestivum* flour (Baifan, 白面), mix with water, and apply lightly; this is very effective. Crush *Sagittaria sagittifolia* leaves and stems with cold water, sweep onto the area with a chicken feather brush; the swelling subsides immediately.

Boil *Alumen* (Baifan, 白矾) powder in water and apply. Mix *Carthami Flos* (Honglanhua, 红蓝花) with vinegar and apply. Boil *Angelicae Dahuricae Radix et Folium* (Baizhi, 白芷) roots and leaves and apply. Pound carp until mushy and apply. Mix *Zinci Melle* (Fengmi, 蜂蜜) with dried *Zingiberis Rhizoma* (Jiang, 干姜) powder and apply. Mix *Pheretima* (Dilong, 地龙) feces with water and apply. Pound *Cannabis Fructus* (Damaizi, 大麻子) juice and apply. Apply water used by lime-burners to wash their vats. Mix soil from leek beds with water and apply. Mix *Ulmus pumila* root bark (Yugenbaipi, 榆根白皮) with egg white and apply. Apply non-water-contacted *Ovis Aries Adip* (Yangzhi, 羊脂) after roasting, and cover with white powder. Grind *Coriandri Fructus* (Huisui, 胡荽) juice and apply. Grind *Terminalia chebula* (Hezi, 诃子) with vinegar and apply. Pound *Phytolaccae Radix* (Guimu, 鬼目) juice and apply. Pound *Perilla Fructus* (Renzi, 荏子) juice and apply. Grind fermented bean paste, take the juice, and apply. Grind *Rehmanniae Radix* (Dihuang, 地黄) juice and apply. Grind bean leaf juice and apply. Grind *Sargassum* (Haizao, 海藻) juice and apply. Mix *Sojae Semen Praeparatum* (Chimo, 豆豉) powder with oil and apply. Mix *Indigo Naturalis* (Qingdai, 青黛) with water and apply. Grind *Pheretima* (Dilong, 地龙) with water and apply. Boil *Oryza sativa* (Sumi, 粟米) and apply. Boil *Acanthopanacis Cortex* (Shinan, 石楠) with wine and apply. Mix *Gallus gallus domesticus* feces with water and apply. Pound *Platanus orientalis* bark and apply. Apply bitter juice. (Administer internally as well.) Pound garlic and apply. (Especially excellent for treating Wuse Dan / Five-Color Dan.)
The *Qianjin Fang* states: Whenever eggs are used in formulas, use those that have broken first; others lack potency. It also states: Among all things in the world, algae are the coldest. For conditions involving heat swelling, toxic Dan, etc., take channel algae, chop finely, cook, pound thoroughly, and apply to the Dan lesion to a thickness of about three fen; replace when dry. I believe this method should not be used for external application. If the pathogen is on the surface, it can still be managed; if suppressed forcibly, the pathogen cannot vent outward and will inevitably enter the interior. One must first administer formulas to support the interior and expel toxins before applying this method.
