If the white sclera (Bai Zhu) has many red streaks, and there is excessive discharge, tearing, and a gritty sensation making it difficult to open the eyes, what is the cause? The answer is: After the onset of eye disease, one often suffers from wind-cold invasion, leading to stagnation of Qi and Blood, obstruction of the nine orifices, resulting in deficiency of Lung Qi and hyperactivity of Heart Fire. Consequently, Heart Blood harasses Lung Metal. It is appropriate to apply Zhenzhu Huye Gao (Pearl Tiger Liquid Ointment) to the eyes and take He Xue Bu Qi Yin (Blood-Nourishing and Qi-Supplementing Decoction).
He Xue Bu Qi Yin (Blood-Nourishing and Qi-Supplementing Decoction)
Fangfeng (Saposhnikoviae Radix, 1 qian), Huangqin (Scutellariae Radix, 1 qian), Manjingzi (Viticis Fructus, 1 qian), Baizhi (Angelicae Dahuricae Radix, 1 qian), Chaihu (Bupleuri Radix, 1 qian), Gancao (Glycyrrhizae Radix et Rhizoma, 5 fen), Danggui (Angelicae Sinensis Radix, 1.5 qian), Shengma (Cimicifugae Rhizoma, 6 fen).
Decoct in water and take orally.
If the eye discharge and tears resemble pus, with redness, swelling, and blurred vision, what is the reason? The answer is: Kidney deficiency and Heart deficiency, termed "Long Hu Jiao Kun" (Dragon and Tiger Interlocked in Distress). It is appropriate to take Kanli Wan (Kanli Pill) and Bushen Wan (Kidney-Supplementing Pill) (formula see Question 11), and apply Tuiyun San (Cloud-Pushing Powder) to the eyes (formula see Question 14).
Kanli Wan (Kanli Pill)
Baizhu (Atractylodis Macrocephalae Rhizoma, earth-fried), Xixin (Asari Radix et Rhizoma), Chuanxiong (Ligusticum Chuanxiong Rhizoma), Caojueming (Spermatum Cassiae, fried), Qianghuo (Notopterygii Rhizoma et Radix), Danggui (Angelicae Sinensis Radix), Wuwei Zi (Schisandrae Chinensis Fructus), Fangfeng (Saposhnikoviae Radix), Guangui (Cinnamomi Cortex), Juhua (Chrysanthemi Flos), Xuanshen (Scrophulariae Radix), Baifuling (Poria, white), Digupi (Lycii Cortex), Qingqiangzi (Semen Celosiae), Cheqianzi (Plantaginis Semen), Gancao (Glycyrrhizae Radix et Rhizoma), Renshen (Ginseng Radix et Rhizoma), Kushen (Sophorae Flavescentis Radix), Huangqin (Scutellariae Radix) (all in equal proportions).
Grind into powder, mix with refined honey to form pills. Take forty pills per dose, washed down with rice soup.
If the eyes shed cold tears upon exposure to wind, with excessive membranes (neomata), blurriness, and pain, what is the cause? The answer is: This is Liver Wood generating Heart Fire; the fire is hyperactive while Lung Metal is deficient, thus failing to control Liver Wood, termed "Dong Xi He Zhan" (East-West Battle). It is appropriate to apply Tuiyun San (Cloud-Pushing Powder) to the eyes (formula see Question 14), and take Xiegan San (Liver-Draining Powder) and Budan San (Gallbladder-Supplementing Powder) (formulas see Questions 3 and 4).
Renshen Tang (Ginseng Decoction) (Not found in standard methods for Renshen Tang, likely an omission; inferred that this etiology also suits taking this formula)

Decoct in water and take warm.
Why do both left and right eyes become mutually red? The answer is: This is caused by Blood pathogen attacking and rushing. Liver insufficiency leads to contention between wind and heat, with pathogens moving back and forth between left and right. The pulse shows either excess or deficiency, hence termed "mutual redness." It is appropriate to apply Chitou San (Red-Head Powder) externally, and take Canzhi Wan (Silkworm Paper Pill) and Shaoyao Tang (Peony Decoction).
Canzhi Wan (Silkworm Paper Pill)
Wancan'e (Bombyx Batryticatus), Chantui (Cicadae Periostracum), Juhua (Chrysanthemi Flos), Qianghuo (Notopterygii Rhizoma et Radix), Gujingcao (Euphrasiae Herba), Gancao (Glycyrrhizae Radix et Rhizoma) (all in equal proportions).
