One *dou* (approx. 10 liters) of silkworm feces (*Bombyx Batryticatus*, Can Sha) is burned to ash together with *Senecio scandens* herb (Qianli Guang). Five bowls of juice are extracted by pouring boiling child's urine over the ashes.
The previously reserved two *liang* of Calamina (Gan Shi) is placed in a copper pot and slowly boiled over mulberry wood fire until the liquid is completely evaporated. When it turns red, it cools down to form a fine powder. One *qian* and five *fen* of Cinnabar (Zhu Sha) is added for later use.
One *liang* of Wu Peng mixed with seven *fen* of Borneol (Bing Pian). One *liang* of Long Sha mixed with one *qian* of Borneol (Bing Pian). One *liang* of Hu Ye mixed with one *qian* and three *fen* of Borneol (Bing Pian).
Any symptoms of redness, swelling, pain, and itching are considered internal eye disorders (Nei Zheng). In severe cases, Hu Ye is the principal herb, used in a dosage of seven *fen*; Long Sha is the assistant herb, used in a dosage of three *fen*; Wu Peng is the adjunct herb, used in a dosage of two *fen*. In mild cases of internal eye disorders, Wu Peng is the principal herb, used in a dosage of five *fen*; Hu Ye is the assistant herb, used in a dosage of three *fen*; Long Sha is the adjunct herb, used in a dosage of two *fen*.
Any nebulae, pterygium-like growths (Yu Rou), and red-white corneal opacities (Yi Zhang) are considered external eye disorders (Wai Zhang). In severe cases, Long Sha is the principal herb, used in a dosage of seven *fen*; Hu Ye is the assistant herb, used in a dosage of three *fen*; Wu Peng is the adjunct herb, used in a dosage of two *fen*.
When applying eye drops, apply them to the outer canthus after meals, ensuring they do not touch the black pupil (cornea). Apply more than ten times daily. If there is a thin nebula on the cornea, use the following prescription:
Feng Lin Gao (Phoenix and Qilin Ointment) as the principal agent, one *qian*; Pearl (Zhen Zhu), three *fen*; Amber (Hu Po), two *fen*; Long Sha, two *fen*; Hu Ye, one *fen*; Gold leaf (Chi Jin), twenty sheets. Grind all into a fine powder and apply to the eyes; the opacity will recede.
Schizonepeta Herb (Jing Jie), Mint Herb (Bo He), Scrophularia Root (Xuan Shen), Saposhnikovia Root (Fang Feng), Angelica Dahurica Root (Bai Zhi), Prunus Armeniaca Seed (Rui Ren), White Peony Root (Bai Shao), Gardenia Fruit (Zhi Zi), Kudzu Root (Gan Ge), Forsythia Fruit (Lian Qiao), Chinese Angelica Root (Dang Gui), Scutellaria Root (Huang Qin), Bupleurum Root (Chai Hu), Cimicifuga Rhizome (Sheng Ma), Plantago Seed (Che Qian Zi), Rehmannia Root (Sheng Di), Equisetum Hiemale (Mu Zei), Asarum Root (Xi Xin), Goji Berry (Gou Qi), Mulberry Bark (Sang Bai Pi), Prunella Spike (Xia Ku Cao), Coptis Rhizome (Huang Lian), Chrysanthemum Flower (Ju Hua), Abalone Shell (Shi Jue Ming), Tribulus Fruit (Ji Li), Atractylodes Macrocephala Rhizome (Bai Zhu), Cyperus Rhizome (Xiang Fu), Phellodendron Bark (Huang Bo). These twenty-eight herbs are used in equal proportions.
This formula has the effect of dispelling wind, removing cloudiness from the eyes, reducing fire, and improving vision, with efficacy like a divine spirit.
Take one *qian* of each of the above herbs, decoct in water to make a concentrated liquid, and filter out the dregs. Add five *qian* of the previously prepared Long Sha and Hu Ye into a copper pot. Slowly pour in the herbal liquid until it is fully absorbed and the medicine is dry. This constitutes Feng Lin Gao. Add one *qian* of prepared Calamina (Gan Shi), one *qian* of White Civet Cat Feces (Bai Ding Xiang), and two *qian* of Centipedia Herb (E Bu Shi Cao). It removes opacities with miraculous effect.
