风化硝一两，红粉五钱，冰片八分。在初秋时节选取大苦瓜，挖去瓤和籽，将元明粉填入其中，悬挂在西北风处，到了冬天自然会有霜析出，这就是风化硝。红粉的制法：挑选荸荠，削去粗皮，洗净后捣碎至极细，用新棉布过滤去除渣滓，澄清粉末并晒干，浸泡在胭脂花的天然汁液中，再次晒干，注意不要见火。或者也可以用赤小豆或白果取粉，浸泡在金花胭脂水中也很好。
上方（指上述配方）用于预防疾病，治疗病后眼睛昏花微红、时常发作的痒痛。因为胭脂的性能是行血，配合红粉、冰片则能拔毒去秽，必须加倍使用风化硝的原因，是因为它咸寒微苦，用来治疗上述病症，就像霜露降下之后，世间还有不清肃的吗？因此依据其德行和色泽来命名此方。
挑选像镜子一样光亮的大朱砂，白矾用水泡过后飞制，炉甘石挑选洁白干净、质地轻浮、放在水上不沉的，捣碎装入罐中，经过熟飞处理，再用黄连一钱，煎煮浓汁滤清，浸泡石头并晒干，各取五钱。月石挑选明亮洁净如石榴子般的，轻粉选取光明大片状的，各三钱。这些药材必须各自准备齐全，临用时才加入。否则颜色鲜红会突然变黑。元明粉、牛黄、明雄黄各二钱，珍珠、石蟹或者紫色的石燕也可以，都要经过飞制。血竭选用上好的麒麟竭，透甲红色的，研磨得极细如灰尘，没有白点才能使用。人乳粉、银箔、熊胆、麝香、乳香、没药，这九味药各一钱，冰片必须是明亮且烧不着的，用量为一钱五分，金箔二百张。金银箔和人乳粉一起研磨容易粉碎。
上方是点眼药的通用方剂。解析其含义：甘石连制（炉甘石与黄连汁制），性凉平，能收敛湿气，配合珍珠、轻粉、石蟹、雄黄则能灵洁去垢腻；朱砂经白矾飞制，味酸能镇邪，配合牛黄、月石、元明粉、熊胆则苦寒而泻火热；金银辟除恶气，人乳滋润燥热，再加上有活血作用的乳香、没药、血竭，以及散气的冰片、麝香，各种疾病都能消除。称为“芙蓉镜”，大概是兼取其质地与色泽而得名。如果没有珍珠，细碾飞制的海螺壳、石决明也可以替代。
One tael of Xiao Ming Fan (Natrii Sulfas Exsiccatus, 风化硝), five qian of Hong Fen (Red Powder, 红粉), and eight fen of Bing Pian (Borneolum Syntheticum, 冰片). In early autumn, select large bitter melons, hollow out the pulp and seeds, fill them with Yuan Ming Fen (Mirabilite, 元明粉), and hang them in a place exposed to the northwest wind. By winter, frost will naturally precipitate; this is Xiao Ming Fan. To prepare Hong Fen: select water chestnuts, peel off the coarse skin, wash them clean, pound them until extremely fine, filter through new cotton cloth to remove dregs, clarify the powder and dry it in the sun, soak it in the natural juice of Carthamus tinctorius flowers (Zhi Zi Hua, 胭脂花), and dry again, avoiding fire. Alternatively, one may use powder from Adzuki beans (Chi Xiao Dou, 赤小豆) or Ginkgo nuts (Bai Guo, 白果), soaked in Jin Hua Yan Dan water (Golden Flower Carmine Water, 金花胭丹水), which is also excellent.
The above formula is used for preventing disease, treating blurred vision with slight redness after illness, and intermittent itching and pain. Since Zhi Zi Hua has the property of promoting blood circulation, when assisted by Hong Fen and Bing Pian, it extracts toxins and removes filth. The reason for doubling the amount of Xiao Ming Fan is that its salty, cold, and slightly bitter nature treats the aforementioned symptoms, akin to how the world becomes clear and serene after frost and dew fall. Hence, the formula is named based on its virtue and color.
Select large Cinnabar (Zhu Sha, 朱砂) as bright as a mirror. Bai Fan (Alumen, 白矾) should be washed by floating in water. Lu Gan Shi (Calamina, 炉甘石) should be selected for being white, clean, light, and floating on water. Crush it, place it in a jar, and process it by "shu fei" (calcination with liquid medium). Then, decoct Huang Lian (Rhizoma Coptidis, 黄连) one qian in strong liquid, filter clearly, soak the stones, and dry them. Use five qian each. Select Yue Shi (Talcum, 月石) that is bright and clean like pomegranate seeds. Select Qing Fen (Calomel, 轻粉) in large, bright pieces. Use three qian each. These ingredients must be prepared separately and added only at the time of use; otherwise, the fresh red color will suddenly turn black. Use two qian each of Yuan Ming Fen, Niu Huang (Calculus Bovis, 牛黄), and Ming Xiong Huang (Realgar, 明雄黄). Zhen Zhu (Margarita, 珍珠), Shi Xie (Shrimp Shell Stone, 石蟹), or purple Shi Yan (Swallow Stone, 石燕) may also be used; all must be processed by "fei". Xue Jie (Dragon's Blood, 血竭) should be high-quality Qilin Jie, transparent red allowing light to pass through, ground extremely fine like dust without white spots before use. Use one qian each of Ren Ru Fen (Human Milk Powder, 人乳粉), Yin Bo (Folium Aurii et Argenti, 银箔), Xiong Dan (Ursi Bile, 熊胆), She Xiang (Moschus, 麝香), Ru Xiang (Olibanum, 乳香), and Mo Yao (Myrrha, 没药). Bing Pian must be bright and non-flammable, using one qian five fen. Use two hundred sheets of Jin Bo (Folium Aurii, 金箔). Grinding Yin Jin Bo (Silver and Gold Foil, 金银箔) together with Ren Ru Fen makes them easier to crush.
The above formula is a general preparation for eye drops. Analyzing its principles: Lu Gan Shi processed with Huang Lian is cool and neutral, astringing dampness; assisted by Zhen Zhu, Qing Fen, Shi Xie, and Xiong Huang, it cleanses spiritually and removes greasy dirt. Zhu Sha processed with Bai Fan is sour and suppresses evil pathogens; assisted by Niu Huang, Yue Shi, Yuan Ming Fen, and Xiong Dan, it is bitter and cold, draining fire and heat. Yin Jin repels malignancy, Ren Ru moistens dryness, along with Ru Xiang, Mo Yao, and Xue Jie which promote blood circulation, and Bing Pian (Borneolum, 片脑) and She Qi (Moschus, 麝脐) which dissipate qi. Thus, various diseases are eliminated. It is called "Fu Rong Jing" (Hibiscus Mirror, 芙蓉镜), likely named for both its texture and color. If Zhen Zhu is unavailable, finely ground and processed Hai Luo Ke (Concha Meretricis, 海螺壳) or Shi Jue Ming (Concha Haliotidis, 石决明) may serve as substitutes.
