凡用膏子，不拘官料草药，必要洗净切细，或煎汁，或捣汁，皆要澄滤浊脚为是。取上面清者，入罐煎熬，
十去七分，将三分存下，方入薄瓷器内，隔水炖浓，下芦荟末收干。要老要嫩，但凭所宜。然焦则无力，嫩
则难收。
珍珠、琥珀、玛瑙、珊瑚，皆所难研者，古人有用火 者，虽易碎，去其真性，又近于燥，不可用。水磨者，
荡去细尘，亏者太过，又不可。不如用布数层包定，铁锤打碎，放开，拣细者入抒钵内，轻轻慢研细筛，真性不
失，亏者不多也。
务将合药料，预先研细，称定包好，煎定膏子，各用器盛定，无一不备。方将各末子称准，并立一处，重筛
去粗末，次将熟蜜入器内，次称膏子入膏蜜化匀，次入细药搅匀得所，方下黄丹、麝香，收定，连器下窖出火毒，
然后入瓷罐收用，愈久愈佳。若骤用，则火猛耳。
治眼之法，用药最难，大热则发，大寒则凝，所以冰片禁用，黄连少用。外点之药，须以消熔敛光为主，
内服之药，须以发散破气为先。初发者降火消风，久病者荡翳发光。若骤补骤泻者，皆能损目，毋欲速，毋放肆，
慎之。
目疾眼药，每每不得速应，故服药者鲜矣。古云∶锅中点水，不如灶底抽薪，点药服药，此为内应外合之意
也。服于食前固不可，服于食后，皆是运动之际，药行四散，亦不得取效。惟于临卧之时，卧而服之，两眼皆合，
精神潜伏，药性上升，必走空窍，故于两目皆应。
凡是制作膏剂，不论使用的是官方配方的草药还是民间草药，都必须将其洗净并切碎。无论是煎煮取汁还是捣碎取汁，都要经过澄清过滤，去除底部的沉淀杂质，只取上层的清液。将清液放入罐中煎熬，蒸发掉十分之三的水分，剩下十分之七的药液，然后倒入薄壁瓷器内，隔水炖煮至浓稠，最后加入芦荟末收干成膏。膏剂的稠度要老一些还是嫩一些，完全根据实际需要而定。但是熬得太焦则药效无力，太嫩则难以成型收膏。
珍珠、琥珀、玛瑙、珊瑚这些药材都很难研磨。古人有用火煅烧的方法，虽然容易打碎，但会破坏其真性，而且性质偏燥，不可使用。用水磨法，虽然能荡去细尘，但损耗太过严重，也不可行。不如用几层布包好，用铁锤敲碎，展开后挑选细小的部分放入研钵中，轻轻缓慢地研磨并过细筛，这样既不失其真性，损耗也不多。
务必将配合使用的药料预先研细，称好重量并包好。煎制好的膏剂，分别用容器盛放，准备齐全。然后将各种粉末药物准确称量，放在一起，再次重筛以去除粗颗粒。接着将熟蜂蜜放入容器中，再将膏剂称量加入，与蜂蜜化匀混合，随后加入细药粉搅拌均匀，最后加入黄丹和麝香，收膏定型。连同容器一起埋入窖中去除“火毒”，然后装入瓷罐收藏备用，存放时间越久越好。如果急于使用，药性猛烈，对眼睛不利。
治疗眼病的方法，用药最为难处。大热性的药会导致病情发散，大寒性的药会导致气血凝滞，所以冰片禁用，黄连少量使用。外用的点眼药，必须以消熔收敛光气为主；内服的汤药，必须以发散破气为先导。初发病症的要降火祛风，久病的要清除翳膜、明亮视力。如果突然进补或突然泻下，都会损伤眼睛，不要追求速度，不要放纵用药，务必谨慎。
治疗眼疾的眼药，往往不能迅速见效，所以服药的人很少。古语说：“往锅里滴水，不如从灶底抽走柴火。”点眼药和服药，这是内外相应、表里合治的意思。在吃饭前服药固然不行，在饭后服药，此时人体处于运动消化之际，药力四散，也不能取得疗效。只有在临睡前，躺着服药，双眼闭合，精神潜伏内敛，药性上升，必然走向空窍，所以对两眼都能产生疗效。
Whenever preparing a plaster (Gao), regardless of whether official or herbal ingredients are used, they must be washed and finely chopped. Whether decocted for juice or pounded for juice, the liquid must be clarified and filtered to remove sediment, retaining only the clear supernatant. This clear liquid is placed in a jar and boiled down until three-tenths have evaporated, leaving seven-tenths. It is then transferred to a thin porcelain vessel, stewed over water until concentrated, and finally mixed with Aloe powder (Luhui) to dry into a paste. The consistency—whether thicker or thinner—should be adjusted according to necessity. However, if burnt, it loses efficacy; if too soft, it cannot be consolidated.
Pearl (Zhenzhu), Amber (Hupo), Agate (Manao), and Coral (Shanhu) are difficult to grind. Ancients sometimes used fire calcination, which facilitates crushing but destroys their true nature and makes them overly drying, rendering them unusable. Water-grinding removes fine dust but causes excessive loss. A better method is to wrap the material in several layers of cloth, crush it with an iron hammer, spread it out, select the fine particles, place them in a mortar, and gently grind slowly before sieving finely. This preserves their true nature with minimal loss.
All medicinal ingredients intended for the formula should be pre-ground fine, weighed, and packaged. The prepared plasters should be stored in separate vessels, fully prepared. Then, weigh each powdered ingredient accurately and gather them together. Sift them again to remove coarse particles. Next, place cooked honey (Shu Mi) into a vessel, add the weighed plaster, and melt/mix them evenly. Add the fine medicinal powders and stir until well combined. Finally, add Lead Tetroxide (Huandan) and Musk (Shexiang), consolidate the plaster, and bury the vessel in a cellar to eliminate "fire toxicity." Then transfer to a porcelain jar for storage; the longer it ages, the better. Immediate use results in a harsh medicinal effect.
The treatment of eye diseases is the most difficult aspect of medication application. Excessively hot herbs cause dispersion of pathology, while excessively cold herbs cause coagulation/stagnation. Therefore, Borneol (Bingpian) is contraindicated, and Coptis Rhizome (Huanglian) is used sparingly. External eye drops should primarily focus on melting and收敛 (astringing/consolidating) light energy. Internal decoctions should prioritize dispersing and breaking up Qi stagnation. For initial onset, reduce Fire and dispel Wind; for chronic conditions, clear nebulae (Yi) and brighten vision. Sudden tonification or sudden purgation both damage the eyes. Do not seek haste, do not act recklessly; exercise caution.
Eye medications often fail to produce rapid results, so few patients take internal medicine. An ancient saying states: "Dropping water into a pot is inferior to removing firewood from the stove bottom." Applying eye drops and taking oral medicine represents the principle of internal-external correspondence and synergy. Taking medicine before meals is ineffective. Taking it after meals is also suboptimal because during digestion/movement, the medicinal action scatters, failing to achieve therapeutic effects. Only when taken just before sleep, lying down with eyes closed, allowing spirit to settle inward, does the medicinal property rise and navigate through the orifices, thereby effectively treating both eyes.
