[Danxi] Wind-margin eye disease involves the eye system, caused by accumulated heat in the upper jiao (upper burner), resulting from diet combined with anger. Stubborn phlegm causes obstruction, turbid qi fails to descend, and clear qi fails to ascend; thus, fire becomes more blazing while water descends further.
After accumulation over a long period, the eyelids swell due to pus exudation, and fine worm-like filaments appear within the eye. Consequently, it persists for years without healing and is characterized by frequent itching. Use Zijin Ointment (Purple Gold Ointment). Wipe away the grease with the foot of a silver hairpin before applying drops. If itching is indeed present, one must remove the parasites to eliminate the root cause. This is because Zijin Ointment merely dispels dampness, wind, and cools the blood. If the condition stems from the aforementioned phlegm formed by diet and anger, one must additionally use Fangfeng Tongsheng San (Wind-Protecting Universal Release Powder) with Xie (Mangxiao/Rhizoma Natri Sulfatis) and Huang (Dahuang/Radix et Rhizoma Rhei) removed, ground into fine powder, mixed evenly with wine, dried, and taken according to the method. Avoid all rich flavors and strong spices, which completes the essence of these methods. (The specific formula for Zijin is unknown; it refers to Huanjing Zijin Dan (Purple Gold Pill for Restoring Vision) in the Eye Section of Lan Shi Mi Zang.)
Fangfeng Tongsheng San (Formula see Epilepsy section)
[World Doctors] Luguanshi San (Calamine Powder) treats Lan Feng Yan (Rotting Wind Eye).
Take an unspecified amount of Luguanshi (Calaminae Lithofossilia). First, soak it seven times in Tongbian (Child's Urine). Next, soak it seven times in thick decoction of Huanglian (Coptidis Rhizoma). Then, soak it seven times in thick decoction of tea from before Guyu (Grain Rain solar term). Combine the residues of these three juices once, then calcine three times. Place it on the ground overnight to eliminate fire energy. Grind finely, add Bingpian (Borneolum Syntheticum) and Shexiang (Moschus), and apply to the eyes with miraculous effect. When calcining Luguanshi, use large pieces of high-quality Zixiaotan (Purple Sky Charcoal), carve a hole in it, and place the Luguanshi inside.
[Danxi] To treat Wind-margin Rotting Eye, soak Er Cansha (Two-stage Silkworm Feces) in Xiangyou (Sesame Oil) for over a month. Filter through multiple layers of silk gauze and apply drops. The longer the duration, the better the effect.
[World Doctors] Zijin Gao (Purple Gold Ointment)
Use Guodan (Lithargyri) processed by water flying. Use more honey and less water. Boil using moderate and gentle heat. Store in a vessel and apply drops.
[Baoming Ji] To treat Yan Chi Xia (Red Blindness of the Eye), wash Qingni Qu (Green Mud Maggots) clean, dry them, and grind into powder. Lie supine with eyes closed. Apply one qian of the medicine onto the eye. After a moment when the medicine spreads, wait briefly and remove the medicine. Red blindness will naturally disappear.
[Dongyuan] Long-standing red and rotting orbits, commonly called Chi Xia (Red Blindness), can be instantly cured by pricking the outer canthus of the eye with a Sanleng needle (Three-edged Needle) to drain damp-heat.
