《本经》主崩中漏下，破子脏中血，症瘕结气，寒热腹痛，无子，阴痿不起，补不足。
发明 阳起石乃云母之根，右肾命门药，下焦虚寒者宜之。黑锡丹用此，正以补命
门阳
气不足也。《本经》治崩中漏下，阳衰不能统摄阴血也。又言破子脏中血，症瘕结气。是
指阴邪畜积而言。用阳起石之咸温，散其所结，则子脏安和，孕自成矣。阴虚火旺者忌用，

《本经》名玄石，俗名吸铁石
辛咸微寒，无毒。入药 过，醋淬七次，研细
，水飞用。
《本经》主周痹风湿，肢节中痛，不可持物，洗洗酸消，除大热烦满及耳聋。
发明 磁石为铁之母，肾与命门药也，惟其磁，故能引铁。《千金》磁朱丸治阴虚龙火

。《济生方》治肾虚耳聋，以磁石豆大一块，同 穿山甲末，绵裹塞耳中，口含生铁一块，
觉耳中如风雨声即通。
《神农本草经》中称之为白石。
味道咸，性温，无毒。颜色洁白，揉搓时像棉絮一样柔软且不脆裂的才是真品，质地坚硬易碎的则是伪品。使用时，需用烧酒淬炼七次，捣碎成细末，再经过水飞法处理后备用。
《神农本草经》记载其主治崩漏（非经期大量出血或淋漓不尽），破除子宫内的瘀血，消散症瘕（腹内结块）和郁结之气，治疗因寒热引起的腹痛，治疗不孕症，治疗阳痿不起，以及补益身体不足。
【发明】阳起石是云母的根部，属于右肾命门（人体生命活动的原动力所在）的药物，适用于下焦虚寒的患者。黑锡丹中使用此药，正是为了补益命门阳气不足。《神农本草经》治疗崩漏，是因为阳气衰弱不能统摄阴血所致。又提到破除子宫内的瘀血、消散症瘕结气，这是指阴邪积聚而言。使用阳起石的咸温之性，可以散开所结聚的病邪，从而使子宫安宁调和，自然能够受孕。阴虚火旺者忌用，因为其药性专门助长阳气。
《神农本草经》中称之为玄石，俗称吸铁石。
味道辛、咸，性微寒，无毒。入药时需经过醋淬炼七次，研成细粉，再经过水飞法处理后备用。
《神农本草经》记载其主治周身痹症及风湿病，肢体关节疼痛，无法持物，身体感觉寒冷且酸痛消减，消除大热、烦闷以及耳聋。
【发明】磁石是铁的母体，属于肾脏与命门的药物，正因为其具有磁性，所以能吸引铁。《千金方》中的磁朱丸用于治疗阴虚导致的龙火上炎（肾阴不足导致虚火上冲），症状包括耳鸣嘈杂、肾虚导致的瞳神散大。这是因为磁石入肾，镇守并滋养真精，使神水不向外流失；朱砂入心，镇守并滋养心血，使邪火不向上侵犯耳目，从而都受到庇护。《神农本草经》主治周身痹症风湿、肢体关节疼痛、身体寒冷酸痛，是利用其辛味来通利痹阻并驱散病邪，利用其重坠之性来去除怯弱并镇固心神，这样阴邪就会退却顺从，肢体关节安宁调和，耳目精明，大热烦闷自然消除。《济生方》治疗肾虚耳聋，取如豆大的一块磁石，同穿山甲粉末一起，用绵布包裹塞入耳中，口中含一块生铁，感觉到耳中有如风雨声时，听力即可通畅。
*Ben Jing* (Shennong's Classic of Materia Medica) calls it Bai Shi (White Stone).
Salty and warm, non-toxic. The genuine product is white in color and feels soft like cotton when rubbed without being brittle; those that are hard and brittle are fake. For medicinal use, quench it seven times in distilled liquor, pound it into fine powder, and process it by water flotation (shui fei).
*Ben Jing* states it treats metrorrhagia and leukorrhea with bleeding (beng zhong lou xia), breaks up blood stasis in the uterus, dissipates masses (zheng jia) and qi stagnation, treats abdominal pain due to alternating cold and heat, infertility, impotence, and tonifies deficiencies.
[Invention] Yang Qi Shi (Calcium Silicate Mineral) is the root of Muscovite (Yun Mu). It is a herb for the Right Kidney and Ming Men (Gate of Vitality) and is suitable for patients with deficiency-cold in the lower jiao. It is used in Hei Xi Dan (Black Tin Pill) precisely to tonify insufficient yang qi of the Ming Men. *Ben Jing* treats metrorrhagia because yang qi is deficient and unable to control yin blood. It also mentions breaking up blood stasis in the uterus and dissipating masses and qi stagnation, which refers to the accumulation of yin pathogens. Using the salty and warm nature of Yang Qi Shi can disperse the accumulated pathogen, thereby calming and harmonizing the uterus, allowing conception to occur naturally. It is contraindicated in cases of yin deficiency with hyperactive fire because its nature specifically assists yang.
*Ben Jing* calls it Xuan Shi (Black Stone), commonly known as Magnetite (Xi Tie Shi).
Pungent and salty, slightly cold, non-toxic. For medicinal use, quench it seven times in vinegar, grind it into fine powder, and process it by water flotation.
*Ben Jing* states it treats generalized bi syndrome (zhou bi) and wind-dampness, pain in the limbs and joints, inability to hold objects, a sensation of cold and soreness/weakness, removes severe heat, fullness, and deafness.
[Invention] Ci Shi (Magnetite) is the mother of iron and is a herb for the Kidney and Ming Men. Because of its magnetism, it can attract iron. Ci Zhu Wan (Magnetite and Cinnabar Pill) from *Qian Jin Fang* treats upward flaming of dragon fire due to yin deficiency, characterized by roaring tinnitus and dilated pupils due to kidney deficiency. This is because Ci Shi enters the kidney, stabilizes and nourishes true essence, preventing the divine fluid from leaking outward. Zhu Sha (Cinnabar) enters the heart, stabilizes and nourishes heart blood, preventing evil fire from invading the ears and eyes, thus both benefiting from protection. *Ben Jing* treats generalized bi syndrome, wind-dampness, limb joint pain, and cold/sore sensations by utilizing its pungency to unblock bi and disperse pathogens, and its heaviness to remove timidity and stabilize the spirit. Consequently, yin pathogens retreat, limbs and joints become harmonious, ears and eyes become clear, and severe heat and fullness are naturally eliminated. *Ji Sheng Fang* treats kidney deficiency deafness by taking a bean-sized piece of Ci Shi, mixing it with powder of Pangolin Scales (Chuan Shan Jia), wrapping it in silk, inserting it into the ear, and holding a piece of raw iron in the mouth. When a sound like wind and rain is felt in the ear, hearing will be restored.
