伏龙肝：
由火与土之气化合而成，味甘、辛兼带咸味，药性温，无毒。古代方剂治疗癫狂、睡眠中受惊梦魇、卒中及邪气侵袭等病症，是因为认为灶中有神明可以驱除幽暗阴邪。主治妇女崩漏和吐血，是因为失血过多会导致中气受损，甘味能补益中气，温性能调和血脉。消除痈肿毒瓦斯，是因为辛味能发散，咸味能软化坚结。促进分娩排出胎盘，以及治疗小儿夜啼，是取其为具有神明的土壤，容易祛除阴滞之邪，且质地沉重具有下坠镇摄的作用。
铛墨即百草霜，是锅膛中间的烟灰，燃烧杂草者称为百草霜。其甘性更为优良，《神农本草经》未记载其气味。观察其主要功效，与伏龙肝相似。凡是血液遇到黑色药物就会停止出血，虫毒恶气遇到辛温药物就会消散，所以《神农本草经》记载其主治虫毒、中恶、吐血、血晕。用酒、水或醋研磨后温热服用。也可外涂金疮（金属利器造成的伤口），有生肌止血的功效。
伏龙肝，即灶台中间对着锅底中心的黄土，取存放十年以上、颜色褐色的为佳，可用醋调匀或捣蒜成泥外敷，用于消除壅滞的痈肿毒瓦斯。加水制成敷剂频繁更换，可辟除时疫、安胎，治疗中风不语、心烦、崩漏吐血、咳逆、祛湿消肿。尿血、遗精、肠风便血、反胃、鼻衄、带下、催生下胞、小儿夜啼等症，均将其研成极细粉末，调水服用。百草霜，是治疗血证的重要药剂，因为黑色能克制红色（血）。主治虫毒、中恶、血晕、吐血、血痢、大便色赤；外涂金疮，生肌止血，但面部疮疡不要涂抹，否则入肉如印记般难以去除。
主治（痘疹合参）：消除痘痈肿，兼止吐泻。百草霜仅在痘疹中出现赤痢时，也用于丸散剂中。
青礞石：
禀受石头中刚猛的性质，味辛、咸，药性平，无毒。体重而性质沉降，辛味主散结，咸味主软坚，重质主堕下，所以《神农本草经》所主治的各种症状都是一贯相通的。
青礞石，用于治疗妇人多年积食停滞，攻刺心腹疼痛，小儿热结，顽痰引起的惊痫，喘急需堕痰下行，消食化积，因此入“滚痰丸”，作为平肝破滞、治疗惊热痰壅的神效药剂。痰见到青礞石，就会化为水液。但是脾虚气弱者忌用。
Fulonggan (Cookstove Earth):
Formed by the Qi of Fire and Earth, it tastes sweet, pungent, and slightly salty. Its nature is warm, and it is non-toxic. Ancient formulas treat conditions such as mania, sleep terrors, stroke, and evil qi invasion because it is believed that the stove contains divine spirits capable of dispelling dark yin pathogens. It primarily treats metrorrhagia (uterine bleeding) and hematemesis (vomiting blood) because excessive blood loss inevitably damages Middle Qi; the sweet flavor tonifies the Middle, and the warm nature harmonizes the blood vessels. It resolves carbuncles, swellings, and toxic vapors due to the dispersing action of the pungent flavor and the softening action of the salty flavor. It induces labor and expels the placenta, and treats night crying in infants, taking advantage of its nature as earth with spiritual properties that easily dispel yin-stagnant pathogens, while its heavy nature provides a downward-purging and calming effect.
Dangmo (Pot Ink) is Baicaoshuang (Hundred-Grass Frost), which is the soot from the middle of the pot. Soot from burned weeds is named Baicaoshuang. Its sweet nature is even more efficacious, though *Shennong Bencao Jing* does not record its flavor or nature. Observing its primary indications, it is similar to Fulonggan. Generally, blood stops upon encountering black substances, and insect toxins or evil qi disperse when encountering pungent and warm substances. Therefore, *Shennong Bencao Jing* states it treats insect toxins, sudden evil qi attack, hematemesis, and blood syncope. It is ground finely with wine, water, or vinegar and taken warm. It can also be applied externally to metal wounds (Jinchuang) to generate flesh and stop bleeding.
Fulonggan refers to the yellow earth at the center of the stove bottom facing the pot. The best quality is aged for ten years or more and has a brown color. It can be mixed with vinegar or mashed garlic for external application to resolve stagnant carbuncles, swellings, and toxic vapors. Mixed with water for frequent dressing changes, it can ward off seasonal epidemics, calm the fetus, treat aphasia due to wind-stroke, restlessness, metrorrhagia, hematemesis, cough with reverse flow, dampness removal, and swelling reduction. For hematuria, spermatorrhea, intestinal wind (blood in stool), regurgitation, epistaxis, leukorrhea, inducing labor, expelling the placenta, and infant night crying, it should be ground into an extremely fine powder and taken mixed with water.
Baicaoshuang is a crucial agent for treating blood disorders because black overcomes red (blood). It treats insect toxins, sudden evil qi attack, blood syncope, hematemesis, bloody dysentery, and red stools. Externally applied to metal wounds, it generates flesh and stops bleeding. However, it should not be applied to facial sores, as it leaves a mark like a seal if it enters the skin.
Main Indications (Integration with Smallpox/Rashes): Resolves smallpox carbuncles and swellings, and simultaneously stops vomiting and diarrhea. Baicaoshuang is used in pills and powders specifically when bloody dysentery occurs during smallpox/rash eruptions.
Qingmengshi (Green Migong Stone):
It possesses the fierce nature inherent in stones. It tastes pungent and salty, its nature is neutral, and it is non-toxic. It is heavy and descending. The pungent flavor disperses nodules, the salty flavor softens hardness, and the heavy weight promotes downward expulsion. Thus, all symptoms treated according to *Shennong Bencao Jing* are consistent with these properties.
Qingmengshi treats chronic food stagnation in women causing stabbing pain in the heart and abdomen, heat accumulation in children, stubborn phlegm causing epilepsy and fright, wheezing requiring phlegm expulsion, and food digestion. Therefore, it is included in Gun Tan Wan (Rolling Phlegm Pill) as a divine agent for soothing the Liver, breaking stagnation, and treating fright-heat and phlegm obstruction. When phlegm encounters Qingmengshi, it transforms into water. However, it is contraindicated for those with Spleen deficiency and weak Qi.
