辛温，有毒。
《本经》主疽疡疥瘙，热气恶疮，癞疾死肌，堕眉，杀痔虫，去黑子息肉。
发明 锻石禀壮火之余烈，故能辟除阴邪湿毒，观《本经》所主疽疡疥瘙，热气
恶疮，
癞疾死肌等，皆外治之用。去黑子者，火气未散，性能灼物，故能去黑子息肉及堕眉也。
《本经》虽不言有毒，而内服之方从无及此，其毒可知。寇氏治中风口 ，以锻石醋炒

，左涂右，右涂左，立便牵正。《千金》治身面疣，用苦酒浸锻石六七日，取汁，频频滴之
自落。又治溺死之人，用化过细灰裹下部，以渗其水即活。又治 疮不合，古冢中锻石浓敷
之。《集玄方》治面靥疣痣，碱水煮滚，化矿灰插糯米拌入灰中，经宿色变如晶，以针微拨

《神农本草经》主治痈疽、疥疮、瘙痒，热气引起的恶疮，癞疾导致的死肌（坏死的肌肉），眉毛脱落，杀灭痔疮虫，去除黑痣和息肉。
【发明】锻石禀受了猛烈火气的余威，所以能够驱除阴邪和湿毒。观察《本经》所主治的痈疽、疥疮、瘙痒，热气恶疮，癞疾死肌等病症，都是外用治疗的方法。去除黑痣的原因，是因为火气尚未消散，药性能够灼烧物体，所以能去除黑痣、息肉以及使眉毛脱落。《本经》虽然没说它有毒，但内服的方剂中从来没有用到过它，其毒性可想而知。寇氏用醋炒过的锻石调涂治疗中风口眼歪斜，左脸歪涂右边，右脸歪涂左边，立刻就能矫正。《千金方》治疗身上和脸上的疣，用苦酒（醋）浸泡锻石六七天，取汁液，频繁滴在患处，疣自然会脱落。又治疗溺水之人，用化成细灰的锻石包裹下部，以吸收水分，人就能救活。又治疗溃疡久不愈合，用古冢中的锻石浓敷患处。《集玄方》治疗面部的雀斑、疣和痣，用碱水煮开，将矿灰化入糯米并拌入灰中，过夜后颜色变得像水晶一样，用针轻轻拨动，点少许在上面，半天后流出汁液剔除药物，不能沾水，两天即可痊愈。《便简方》治疗腮部肿痛，用醋调和陈年的锻石外敷。《肘后备急方》治疗烫伤火烧，用陈年锻石调和油外敷。又治疗刀伤金创，用锻石包裹伤口，疼痛立即停止，出血即止，但不能沾水，沾水就会烂肉。
又名海浮石
咸平，无毒。需经过水飞法处理后使用。
【发明】海浮石是水沫凝结而成，色白体轻。所以能治疗上焦痰热，止咳，点眼去翳。敷治痘疮痈肿，功效最为迅速。又治疗各种淋证，消散积块，都是取其咸味能软坚散结的意思。消除瘿瘤、结核、疝气，然而只适合实证患者。虚证患者误服，病情恶化最快，因为它的药性专门克制肺胃之气。南海有浮于水的石头和沉于水的香，专门利用物性的相反，来治疗病气的阻逆。
Acrid, warm, toxic.
*Shennong Bencao Jing* (Divine Farmer's Materia Medica) indicates it treats carbuncles and sores (ju yang), scabies and itching (sao sao), hot-heat malignant sores (re qi e chuang), leprosy causing necrotic muscle (lai ji si ji), loss of eyebrows, killing hemorrhoid worms, removing black moles and polyps.
[Invention] Duan Shi (Calcined Stone) inherits the residual intensity of fierce fire, thus it can repel yin pathogenic factors and damp-toxins. Observing the indications in *Shennong Bencao Jing* such as carbuncles, scabies, itching, hot-heat malignant sores, and leprosy with necrotic muscle, these are all applications for external treatment. The reason for removing black moles is that the fire energy has not dissipated; its nature can cauterize objects, thus it can remove black moles, polyps, and induce eyebrow loss. Although *Shennong Bencao Jing* does not mention toxicity, there are no internal prescriptions using this herb, indicating its toxicity is considerable. Kou Shi treated facial paralysis (stroke-induced deviation of mouth and eye) by stir-frying Duan Shi with vinegar and applying the paste: applied to the unaffected side if the face deviated to the left, and vice versa, resulting in immediate correction. *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) treats warts on the body and face by soaking Duan Shi in bitter wine (vinegar) for six or seven days, taking the juice, and dripping it frequently onto the lesions until they fall off naturally. It also treats drowning victims by wrapping the lower body with finely powdered calcined ash to absorb moisture, reviving the patient. It treats non-healing ulcers by applying thick layers of Duan Shi from ancient tombs. *Jixuan Fang* treats facial freckles, warts, and nevi by boiling alkali water, dissolving mineral ash into glutinous rice mixed with the ash, leaving it overnight until the color becomes crystal-like, gently manipulating with a needle, applying a small amount, allowing fluid to exude after half a day, then removing the medication without letting it touch water, curing within two days. *Bianjian Fang* treats swollen and painful cheeks by mixing aged Duan Shi with vinegar for topical application. *Zhouhou Beiji Fang* (Emergency Prescriptions Kept Up One's Sleeve) treats burns and scalds by mixing old Duan Shi with oil for topical application. It also treats knife wounds and metal injuries by wrapping the wound with Duan Shi, immediately stopping pain and bleeding, but must not touch water, as contact causes flesh rot.
Also known as Hai Shi (Sea Floating Stone).
Salty, neutral, non-toxic. Use after being processed by water-grinding (shui fei).
[Invention] Hai Shi is formed from condensed sea foam, white in color and light in weight. Therefore, it treats phlegm-heat in the Upper Jiao (Upper Burner), stops cough, removes corneal opacities when applied to the eyes, and treats acne and carbuncles with rapid efficacy. It also treats various types of Lin syndrome (dysuria) and dissipates accumulations, utilizing the principle that saltiness can soften hardness. It eliminates goiter, tubercles, and hernias, but is only suitable for excess syndromes. If mistakenly administered to deficiency syndromes, deterioration occurs rapidly because its nature specifically depletes the Qi of the Lung and Stomach. In the South Sea, there are stones that float on water and aromatics that sink, specifically utilizing the opposition of material properties to treat the obstruction and reversal of pathological Qi.
