古代歌诀说：不用刀针切割，全凭此药方。
珍珠（一钱五分） 玛瑙（一钱五分） 琥珀（一钱五分） 珊瑚（一钱五分，以上四味药材，均需用豆腐煮过，再研磨） 硼砂（五分） 熊胆（用笋壳盛装，烘干至脆，研成粉末，五分） 龙脑（四分） 麝香（二分五厘） 瓜蒌皮（七分五厘） 朱砂（细研并用水飞法处理，七分五厘） 黄连末（去除须、芦头，研细，五分） 明乳香（在箬竹叶上炙烤至干，五分） 没药（在箬竹叶上炙烤至干，五分） 炉甘石（按照方法炮制为主，一两五钱）
以上诸药，分别研成细末，用细粉罗筛过，再按分量称定，混合在一起，研磨一万次，再用棉纸筛下，装入瓷罐中收藏备用。其疗效如神。
制备炉甘石的方法：选取上等炉甘石半斤，用一个银铺内的大紫土罐，将甘石放入罐内，外用紫土泥封口，选择一间洁净的房间，在地上安置三根大铁钉，将罐稳固地搁在上面，四周用栗炭覆盖，上下点火，从早到晚为度，研细，用粉罗筛下，用水飞法处理，仍等候药水来制约。再用：
鹅不食草 黄连 黄柏 黄芩 当归 生地 栀子 连翘 赤芍 薄荷 大黄 细辛
白芷 羌活 独活 甘草 胆草 红花 杏仁 白菊 防风 荆芥 蔓荆子 蕤仁（各一钱）
桃叶 桑叶 枇杷叶 槐叶 杏叶（各七片）
加入两大碗水，煎至一碗，去渣，加入金银箔各七张，再熬至一盅，用经过上述处理的炉甘石二两，放入洁净的铜器内，和匀，隔水蒸干，取出，再加入金银箔各七张，选择清爽的天气，露天放置一夜，晒一天，以吸收日月的精华，配合药物使用才有神效。鉴别甘石的标准是：形状像羊脑，白得像雪，松得像花，才是好的。如果沉重黑黯，就不堪使用，用了也没有功效，而且会有损害，务必谨慎。
另一个方子：用经过炮制的炉甘石二钱，朱砂、硼砂各五分，研细经常点眼，也有效。
Use clean boiling water, held in a clean tea cup. Use a clean piece of plain-colored silk cloth to wash the affected area while it is still hot. After washing, if the water becomes turbid, change the water and wash again. Continue until the water runs clear without any impurities. Repeat this process several times until healed. No medicinal herbs are added to the water; hence it is called "Natural Water" (Tianran Shui).
An ancient song states: "No need for knives or needles, rely entirely on this prescription."
Zhenzhu Pearl (1.5 qian) Manao Agate (1.5 qian) Hupo Amber (1.5 qian) Shanhu Coral (1.5 qian; the above four ingredients must be boiled with tofu, then ground) Pengsha Borax (0.5 qian) Xiongdan Bear Bile (held in bamboo sheath, dried until crisp, ground into powder, 0.5 qian) Longnao Dragon Brain [Borneolum Syntheticum] (0.4 qian) Shexiang Musk (0.25 qian) Gualoupi Trichosanthis Pericarpium (0.75 qian) Zhusha Cinnabaris (finely ground and processed by water levigation, 0.75 qian) Huanglian Rhizoma Coptidis (remove roots and rhizome nodes, grind finely, 0.5 qian) Ming Ruxiang Resina Draconis (roasted dry over bamboo leaves, 0.5 qian) Moyao Resina Commiphorae (roasted dry over bamboo leaves, 0.5 qian) Luganshi Calamina (processed according to method, 1.5 liang)
All the above medicines should be individually ground into fine powders, sifted through a fine mesh sieve, weighed accurately according to the dosage, mixed together, and pounded ten thousand times. Then, pass through cotton paper again, and store in porcelain jars for use. Its efficacy is miraculous.
Method for preparing Luganshi Calamina: Select half a jin of premium Calamina. Place it in a large purple clay pot used in silver workshops. Seal the mouth of the pot with purple clay mud. Choose a clean room, place three large iron nails on the ground, and stabilize the pot on them. Cover the surroundings with chestnut charcoal. Apply fire from top and bottom, continuing from morning to evening. Grind finely, sift through a powder sieve, and process by water levigation. Still wait for the herbal decoction to treat it. Then use:
Ebusicao Herba Centipedae (1 qian each) Huanglian Rhizoma Coptidis Huangbai Cortex Phellodendri Huangqin Radix Scutellariae Danggui Radix Angelicae Sinensis Shengdi Rehmanniae Radix Zizhi Fructus Gardeniae Lianqiao Forsythiae Fructus Chishao Radix Paeoniae Rubra Bohe Herba Menthae Dahuang Radix et Rhizoma Rhei Xixin Herba Asari Baizhi Radix Angelicae Dahua Qianghuo Rhizoma Notopterygii Duhuo Radix Angelicae Pubescentis Gancao Radix Glycyrrhizae Dancao Herba Scutellariae Barbata Honghua Flos Carthami Xingren Semen Armeniacae Baiju Flos Chrysanthemi Fangfeng Radix Saposhnikoviae Jingjie Herba Schizonepetae Manjingzi Fructus Viticis Ruiren Semen Prunellaee (1 qian each) Taoye Folium Persicae Sangye Folium Mori Pipaye Folium Eriobotryae Huaiye Folium Sophorae Xingye Folium Armeniacae (7 leaves each)
Add two large bowls of water, decoct until one bowl remains. Remove the dregs. Add seven sheets each of Jinbo Gold Foil and Yinbo Silver Foil. Decoct further until one cup remains. Take two liang of the prepared Luganshi Calamina, place it in a clean copper vessel, mix evenly, and steam-dry over a water bath. Remove it. Add seven more sheets each of gold and silver foil. On a clear day, expose it to the night dew overnight, and sun-dry it during the day to absorb the essence of the sun and moon. When combined with the medicine, it yields miraculous results. The criterion for identifying good Calamina is: shape like sheep brain, white as snow, loose as flowers. If it is heavy, dark, and dull, it is unsuitable for use; using it will be ineffective and potentially harmful. Be cautious.
Another prescription: Use two qian of prepared Luganshi Calamina, 0.5 qian each of Zhusha Cinnabaris and Pengsha Borax. Grind finely and apply frequently to the eyes. It is also effective.
