《医说》记载：白石人董守约，深受香港脚（足部湿毒肿痛之病）攻注之苦，有人告诉他用槌子敲击数只螺蛳，将肉敷在大腿上部，便感觉冷气下行至足部而痊愈。这是因为螺蛳的性能能够泌别清浊，所以能治疗香港脚的湿热证。
顾安中，是广德人，长期患有香港脚，筋脉拘急、腿部肿胀，行走困难，于是前往湖州搭乘船只。船舱里先有一袋物品，因为腿部疼痛，他便把腿搁在这袋子上，微微觉得不痛了，而且筋脉舒缓不再拘急。于是他问船夫：袋子里装的是什么？船夫回答：是木瓜。
自序说：眼睛，是五官之一。如果不明亮就无法明察事理，所以眼睛很重要。治疗眼病有专门的科室，也是因为它的重要性。现在考证并列出名方十五首，供人们斟酌其适宜性而使用，这也是恢复视力的一种帮助。
荆芥 蔓荆子 菊花 白芷 麻黄（去节） 桃仁（去皮尖） 红花（酒炒） 防风 川芎（各五分） 当归（酒洗） 草决明 石决明 白芍药（酒炒） 甘草（各一钱）
眼部疼痛、红肿者，此方主治。
疼痛，是因为邪气实盛。发红，是因为风热损伤血分。肿胀，是因为风热侵袭所致。这个方剂中，荆芥、菊花、蔓荆子、白芷、麻黄、防风，可以疏散风邪，也可以清除热邪，风热去除，那么红肿也就消除了。桃仁、红花、当归、芍药、草决明和石决明，可以消除瘀血，可以滋养血液，也可以调和肝脏，瘀血消除则不痛，养血调和肝脏则视力恢复。至于甘草，是用来调和诸药并调理目气的。
熟地黄（二两） 生地黄 山药 山茱萸 当归梢 五味子 牡丹皮 柴胡（各五钱） 泽泻 茯神（各二钱五分）
肾虚导致视力昏暗不明者，此方主治。
精产生气，气产生神，所以肾精一旦虚弱，则阳光（指虚火）独亢。阳光独亢，则壮火消耗正气，无法产生神气，令人视力昏暗不明。王冰说：“壮水之主，以制阳光。”所以使用生地黄、熟地黄、山茱萸、五味子、当归梢、泽泻、丹皮等气味浓厚的药物，来滋阴养肾，滋阴则肾火自然下降，养肾则精液自然生成。至于山药，是用来补益脾胃从而培补万物之母（脾为后天之本，气血生化之源）。
According to *Yi Shuo* (Medical Narratives): Dong Shouyue, a native of Baishi, suffered severely from Hongxiangjiao (a condition characterized by damp-heat toxicity in the lower limbs causing swelling and pain). Someone advised him to crush several snails (*Concha Meretrix*), apply the flesh to his upper thighs, after which he felt the cold qi descend to his feet and was relieved. This is because snails have the property of separating the clear from the turbid, thus they can treat the damp-heat syndrome of Hongxiangjiao.
Gu Anzhong, a native of Guangde, had long suffered from Hongxiangjiao, with tendon tightness and leg swelling, making walking impossible. He went to Huzhou and boarded a boat. There was a bag of items in the cabin; due to leg pain, he rested his leg on the bag and felt slight relief from pain, and his tendons relaxed without tightness. He asked the boatman: "What is in this bag?" The boatman replied: "Quince."
In his preface, he stated: The eyes are one of the five sense organs. Without clarity, one cannot perceive wisdom; thus, the eyes are of great importance. Ophthalmology exists as a specialized department precisely because of this importance. Herein, fifteen famous prescriptions are examined and listed. If people consider their suitability and use them appropriately, it will be a help in restoring vision.
Jingjie (Schizonepetae Herba), Mandingzi (Viticis Semen), Juhua (Chrysanthemi Flos), Baizhi (Angelicae Dahuricae Radix), Mahuang (Ephedrae Herba, nodes removed), Taoren (Persicae Semen, skin and tips removed), Honghua (Carthami Flos, wine-fried), Fangfeng (Saposhnikoviae Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma) (each 5 fen); Danggui (Angelicae Sinensis Radix, washed with wine), Caojueming (Cassiae Semen), Shijueming (Concha Argo), Shaoyao (Paeoniae Radix Alba, wine-fried), Gancao (Glycyrrhizae Radix et Rhizoma) (each 1 qian).
This prescription is indicated for eye pain, redness, and swelling.
Pain indicates excess pathogenic factors. Redness indicates wind-heat injuring the blood. Swelling indicates infiltration by wind-heat. In this formula, Jingjie, Juhua, Mandingzi, Baizhi, Mahuang, and Fangfeng can dispel wind and clear heat. Once wind-heat is eliminated, redness and swelling subside. Taoren, Honghua, Danggui, Shaoyao, Caojueming, and Shijueming can resolve stasis, nourish blood, and harmonize the Liver. When stasis resolves, pain ceases; when blood is nourished and the Liver is harmonized, vision is restored. Gancao serves to harmonize the various herbs and regulate the Qi of the eyes.
Shudihuang (Rehmanniae Radix Praeparata, 2 liang), Shengdihuang (Rehmanniae Radix), Shanyao (Dioscoreae Rhizoma), Shanzhuyu (Corni Fructus), Dangguishao (tip of Angelicae Sinensis Radix), Wuweizi (Schisandrae Fructus), Mudanpi (Moutan Cortex), Chaihu (Bupleuri Radix) (each 5 qian); Zexie (Alismatis Rhizoma), Fushen (Poria cum Radix Pini) (each 2.5 qian).
This prescription is indicated for dim vision due to Kidney deficiency.
Essence generates Qi, and Qi generates Shen (Spirit). Therefore, if Kidney essence is deficient, Yang fire (hyperactive fire) acts alone. When Yang fire acts alone, vigorous fire consumes Qi, failing to generate Shen, leading to dim vision. Wang Bing said: "Strengthen the master of Water to control Yang fire." Thus, Shengdihuang, Shudihuang, Shanzhuyu, Wuweizi, Dangguishao, Zexie, and Mudanpi, which are substances with strong flavors, are used to nourish Yin and tonify the Kidney. Nourishing Yin causes Kidney fire to descend naturally; tonifying the Kidney causes Essence to generate spontaneously. Shanyao is used to benefit the Spleen and cultivate the mother of all things (the Spleen being the source of postnatal Qi and Blood).
For those suffering from eye diseases after middle age, tonification is appropriate rather than purgation. This can be said to have opened the eyes of the world! Li Dongyuan's prescription approaches this principle closely.
