【石蚕】
药性无毒。主治金创出血，促进肌肉生长，破除石淋（泌尿系结石），消散血结。研磨后服用，可排出碎石。产于海岸岩石旁，形状像蚕，实质是石头。（今附）
臣禹锡等人考证《药诀》记载：石蚕，味苦，性热，有毒。
主治小儿惊风，化痰涎，可与各种药物配合制成丸剂服用。应用瓷器储存，不可接触金银器具，即使密封严密，金石之气仍能渗透。道家多使用，世俗医方中也不甚常用。（新定）
《图经本草》在钟乳石条目下已有详细图文记载。
【石脑油】
《衍义》说：真正的石脑油难以收集，容易渗漏腐蚀器物。现在入药最少，烧炼时或许需要。仍常用有油脂的器皿（去声，指盛油的容器）来储存。另外研磨生砒霜，加入石脑油再次研磨成膏状，放入坩埚内，用干净的瓦片盖好，放在火上，等到锅子红透、油尽为止，取出。再研磨，再加入油，再上火，总共如此操作两次，砒霜的药性就被伏制住了。
【白瓷瓦/定州瓦】
性平，无毒。主治妇女白带过多及白崩，止呕吐，破血，止血。用水研磨后涂抹疮疡，可消除瘢痕。定州出产的质量最好，其余都不如它。（唐本先附）
经验后方：治疗鼻衄（鼻出血）久治不愈。取定州白瓷，细捣研为粉末，每次取一耳勺大小的量，纳入鼻中，立即止血。梅师方：治疗人面部突然患上赤黑丹毒，状如疥疮，若不急治，全身都会死亡。如果是白丹：取白瓷瓦末，与猪胆汁调和后涂抹。
【乌古瓦】
性寒，无毒。用水煮或浸泡取汁饮用，可止消渴（糖尿病症状）。取屋顶上年深日久者质量最好。（唐本先附）
臣禹锡等人考证《药性论》记载：乌古瓦，也可以单用。煎汤服用，能解除人体中的大热。日华子说：性冷，并止小便，煎汁服用。
陈藏器：主治汤火烫伤，应当取土底深处、既古老又湿润的三角瓦片。灸治牙痛法：找三个姓不同的童子，等到星星刚出来时，指着第一颗星星，在下面架起三角瓦用火灸之。
[Shican (Stone Silkworm)]
The medicinal property is non-toxic. It primarily treats traumatic injuries with bleeding, promotes muscle regeneration, breaks down lithiasis (urinary calculi), and dissipates blood stasis. When ground and ingested, it facilitates the expulsion of stone fragments. It grows beside rocks on the coast, resembling a silkworm in shape, but its substance is stone. (Added currently)
Minister Yuxi et al. verified according to *Yao Jue*: Shican has a bitter taste, is hot in nature, and is toxic.
It treats infantile convulsions, resolves phlegm-fluid retention, and can be combined with various herbs to make pills for oral administration. It should be stored in porcelain vessels; contact with gold or silver utensils must be avoided, as the metallic qi can permeate even tightly sealed containers. It is frequently used by Daoists, though not commonly required in secular medical prescriptions. (Newly defined)
Illustrations and descriptions are provided under the entry for *Zhongru Shi* (Gypsum Fibrosum) in *Tujing Bencao*.
[Shinao You (Petroleum/Naphtha)]
*Yanyi* states: Genuine Shinao You is difficult to collect and tends to seep into and corrode vessels. Its use in medicine is now minimal, though it may be needed in calcination processes. It is still commonly stored in oil-containing vessels (qu sheng, referring to vessels holding oil). Additionally, raw arsenic trioxide (Pishuang) is ground, mixed with Shinao You, and re-ground into a paste. This mixture is placed in a crucible, covered with clean tile shards, and heated over fire until the vessel glows red and the oil is exhausted. The residue is removed. The process of grinding and adding oil followed by heating is repeated twice in total, thereby stabilizing (Fu) the properties of the arsenic trioxide.
[Bai Ci Wa / Dingzhou Tile]
Nature is neutral, toxicity is none. It treats leukorrhea and white flooding in women, stops vomiting, breaks blood stasis, and stops bleeding. When ground with water and applied topically to sores, it eliminates scars. Those from Dingzhou are of superior quality; others are inferior. (Previously added in *Tang Bencao*)
Empirical Later Formulas: For treating persistent epistaxis (nosebleed). Take white porcelain from Dingzhou, finely grind into powder. Each time, take an amount equivalent to one ear-spoonful, insufflate into the nose, and bleeding stops immediately. Mei Shi Fang: For treating sudden onset of erysipelas-like red-black dermatosis on the face and body, resembling scabies. If not treated urgently, it becomes fatal throughout the body. For white dermatosis: Take powder from white porcelain tiles, mix with pig bile, and apply topically.
[Wugu Wa (Old Roof Tiles)]
Nature is cold, toxicity is none. Boiling in water or soaking to extract juice and drinking it stops polydipsia (excessive thirst). Tiles that have been on roofs for many years are of best quality. (Previously added in *Tang Bencao*)
Minister Yuxi et al. verified according to *Yao Xing Lun*: Wugu Wa can also be used alone. Decocted in water and taken orally, it resolves severe internal heat. Rihua Zi states: It is cold in nature, stops frequent urination, and when decocted into juice and taken orally...
Chen Cangqi: Treats scalds and burns. One should select deep-soil, ancient, and moist triangular tiles. Method for moxibustion for toothache: Find three boys surnamed differently. Wait until the first star appears in the sky, point to this first star, and perform moxibustion using a triangular tile placed beneath the fire.
