不灰木
性大寒。主治热痱疮，与枣叶、锻石混合制成粉末，外敷于患处。产于上党地区。形状像腐烂的木头，焚烧时不会燃烧，属于石类矿物。（今附）
《图经本草》记载：不灰木产于上党，如今泽州、潞州的山中都有出产，大概属于石类矿物。它的颜色青白，质地像腐烂的木头，焚烧时不燃烧，因此得名。有人说它是滑石的根部，凡是有滑石的地方都有出产，也叫做无灰木。采集没有固定时间。如今处州山中出产一种松石，外形像松树干但实质是石头，有人说松树久埋化为石头，人们多用来装饰山亭，并雕琢成枕头。虽然不入药，但与不灰木相似，所以附记于此。
陈藏器说：烧制时要先将其劈破，用牛乳煮过后再烧，用黄牛粪作为燃料烧成灰。中和二年，在李宗处见到此法流传。《丹房镜源》记载：不灰木可用于煮汞。
蓬砂
味苦、辛，性暖，无毒。能消痰止咳，破除症结，治疗喉痹。也可用于焊接金银。又名硼砂。（新补 见《日华子本草》）
《图经本草》内容已在“砂”条下详述。
《衍义》说：蓬砂含服化津，可治疗喉中肿痛，膈上的痰热，初起时及时治疗，不会发展成喉痹，也能缓慢见效。产自南番（南方海外地区）的，颜色深褐，味道平和，药效迅速。产自西戎（西方少数民族地区）的，颜色白，味道焦涩，药效缓慢，也不适合用于焊接。
铅霜
性冷，无毒。能消痰，止惊悸，解酒毒，治疗胸膈烦闷，中风痰实，止渴。（新补 见《日华子本草》）
《图经本草》内容已在“铅”条下详述。
《简要济众方》：治疗处女月经淋漓涩滞，心烦恍惚。将铅白霜细研为散剂，每次服用一钱，用温地黄汁一合调服。
用生干地黄煎汤调服也可以。《十全博救方》：治疗鼻衄（鼻出血）的方子：将铅白霜研为末，取井水调服一字量。
《衍义》说：铅霜，《图经本草》已记载其制作方法，用于治疗上膈热涎阻塞。涂抹木瓜可去除其酸味，这是金克木的原理。
Buhui Wood (Buhui Mu)
Nature: Greatly Cold. Indications: Mainly treats heat-related prickly heat sores (Re Fei Chuang). Preparation: Mixed with jujube leaves and calcined stone powder, applied externally to the body. Origin: Produced in Shangdang. Description: Resembles rotten wood; does not burn when fired; belongs to the category of stones. (Added later)
*Tu Jing Ben Cao* states: Buhui Wood is produced in Shangdang; currently found in the mountains of Ze and Lu prefectures. It generally belongs to the stone category. Its color is greenish-white like rotten wood, and it does not burn when fired, hence its name. Some say it is the root of Talcum (Huashi); it is found wherever Talcum is found, also called Wuhui Wood. There is no specific time for harvesting. Currently, a type of "Pine Stone" (Songshi) is produced in the mountains of Chuzhou. It resembles pine trunks but is solid stone; some claim old pines transform into stone over time. People often use it to decorate mountain pavilions and carve them into pillows. Although not used in medicine, it is similar to Buhui Wood, so it is appended here.
Chen Cangqi says: To process it, chop it open, boil in cow's milk, then fire it again, using yellow cow dung as fuel to turn it into ash. In the second year of Zhonghe era, this method was seen circulating at Li Zong's place. *Dan Fang Jing Yuan* records: Buhui Wood is used to process mercury.
Pengsha (Peng Sha)
Flavor: Bitter, Pungent. Nature: Warm. Toxicity: Non-toxic. Actions: Resolves phlegm, stops coughing, breaks up masses/knots, treats throat obstruction (Hou Bi). Usage: Also used for soldering gold and silver. Alternative Name: Borax (Pengsha). (Newly supplemented, see *Ri Hua Zi Ben Cao*)
*TU Jing Ben Cao* content is detailed under the entry for "Sha" (Sand/Mineral).
*Yan Yi* states: Pengsha, when held in the mouth to dissolve and swallow the saliva, treats swelling and pain in the throat, and phlegm-heat above the diaphragm. If treated early upon initial sensation, it will not develop into Hou Bi, or can achieve effect gradually. Those from Nanfan (Southern foreign regions) are dark brown in color, have a mild flavor, and act quickly. Those from Xirong (Western barbarian regions) are white in color, have a scorched/bitter taste, act slowly, and are unsuitable for soldering.
Qianshuang (Qian Shuang)
Nature: Cold. Toxicity: Non-toxic. Actions: Resolves phlegm, stops palpitations/fright, resolves alcohol toxicity, treats chest/diaphragm oppression/stuffiness, wind-stroke with phlegm-solidity, stops thirst. (Newly supplemented, see *Ri Hua Zi Ben Cao*)
*TU Jing Ben Cao* content is detailed under the entry for "Qian" (Lead).
*Jian Yao Ji Zhong Fang*: Treats virgins with scanty, obstructed menstruation, mental restlessness, and confusion. Grind Qian Bai Shuang (Lead Frost) finely into a powder. Take one qian per dose, mixed with one he of warm Rehmannia juice.
Mixing with decoction of dried fresh Rehmannia is also acceptable. *Shi Quan Bo Jiu Fang*: Prescription for epistaxis (nosebleed): Grind Qian Bai Shuang into powder, mix with a yi measure of fresh well water.
*Yan Yi* states: Regarding Qianshuang, *Tu Jing* has already recorded its preparation method. It treats upper diaphragm heat-phlegm obstruction. Applying it to papaya removes its sour taste; this is due to Metal overcoming Wood.
