【雌黄】
味辛、甘，性平，大寒，有毒。主治恶疮（严重的皮肤溃疡），头秃（头部脱发），痂疥（结痂的疥癣），杀灭毒虫虱子，治疗身体瘙痒，驱除邪气，解除各种毒素。腐蚀鼻腔中的息肉，治疗下部（生殖器或肛门区域）疮疡，消除面部白斑，消散皮肤上的死肌，以及因恍惚产生的邪气，杀灭蜂蛇毒。需经过炼制后使用。长期服用可轻身（使身体轻盈），延年益寿，使人头脑充实。产于武都山谷，与雄黄同山共生。其阴山若有金矿，金精之气熏蒸则生成雌黄，采集没有固定时间。现今出产于武都仇池的雌黄，被称为“武都仇池黄”，颜色略带赤色。出产于扶南林邑的被称为“昆仑黄”，颜色如金，但质地较脆，使用既稀少，又比昆仑黄便宜。《仙经》中没有单独服用的方法，只是将其与丹砂、雄黄共同飞炼成丹药。金精是雌黄，铜精是空青，而服用空青反而胜过雌黄，其中的道理难以明了。（出自《新修本草》四三页，《大观本草》卷四，《政和本草》一○三页）
【石钟乳】
味甘，性温，无毒。主治咳嗽气逆，明目，补益精髓，安定五脏，通利关节，通畅九窍。促进乳汁分泌，补气，补虚损，治疗脚部软弱疼痛发冷，下焦（肾与膀胱等部位）损伤衰竭，强壮阴气。长期服用可延年益寿，面色红润，延缓衰老，使人易于生育。不经过炼制直接服用，会导致淋证（小便频数短涩、滴沥刺痛）。又名公乳，又名芦石，又名夏石。产于少室山谷及泰山，采集没有固定时间。（以蛇床子为使药，畏牡丹、玄石、牡蒙，恶紫石英、[某]草。）
最早产自始兴，而江陵及东部名山的石洞中也有出产。只有中间通透、轻薄如鹅翎管，破碎后如指甲片，中间没有雁齿状纹理，且光泽明亮的才是上品。长的可达一二尺。颜色为黄色，用苦酒（醋）清洗刷拭后变白。《仙经》中较少使用它。而世俗医方中非常看重它，价格也很昂贵。（出自《新修本草》一五页，《大观本草》卷三，《政和本草》八三页）
[Cinnabar Yellow / Orpiment (Cis Huang)]
Pungent and sweet in flavor, neutral and extremely cold in nature, toxic. It treats malignant sores (severe skin ulcers), alopecia capitis (hair loss on the head), scabies with crusts (scabies with scabs), kills poisonous insects and lice, alleviates pruritus corporis (body itching), expels pathogenic factors, and resolves various toxins. It cauterizes nasal polyps, treats sores in the lower jiao (genital or anal region), disperses vitiligo on the face, dissipates dead muscle tissue on the skin, and eliminates pathogenic factors arising from mental confusion; it also neutralizes venom from bees and snakes. It must be refined before use. Long-term consumption lightens the body, prolongs life, and enriches the brain. It is produced in the valleys of Wudu, growing in the same mountains as Realgar (Xiong Huang). Where there are gold deposits in the shady mountains, the essence of gold fumes to generate Cis Huang; it can be harvested at any time. The Cis Huang currently produced in Qiuchi, Wudu, is called "Wudu Qiuchi Huang," which has a slightly reddish hue. The one produced in Linyi, Funan, is called "Kunlun Huang," which is golden in color but brittle; it is used sparingly and is cheaper than Kunlun Huang. The *Immortal Classics* do not prescribe single-herb consumption; it is only combined with Cinnabar (Dan Sha) and Realgar (Xiong Huang) for sublimation into elixirs. The essence of gold is Cis Huang, and the essence of copper is Azurite (Kong Qing); yet consuming Azurite is considered superior to Cis Huang, the rationale for which is difficult to comprehend. (From *Xinxiu Bencao*, p. 43; *Daguan Bencao*, Vol. 4; *Zhenghe Bencao*, p. 103)
[Stalactite / Spelaeothem (Shi Zhong Ru)]
Sweet in flavor, warm in nature, non-toxic. It treats cough with asthma (coughing and wheezing), brightens the eyes, benefits the essence, calms the five zang organs, unblocks the joints, and opens the nine orifices. It promotes lactation, tonifies qi, supplements deficiency and damage, treats weakness and cold pain in the legs, addresses exhaustion of the lower jiao (kidneys and bladder), and strengthens yin. Long-term consumption prolongs life and longevity, improves complexion, prevents aging, and facilitates fertility. If consumed unrefined, it causes lin syndrome (dysuria). It is also known as Gong Ru, Lu Shi, and Xia Shi. It grows in the valleys of Mount Shao and Mount Tai; it can be harvested at any time. (It uses Cnidium Fruit (She Chuang Zi) as an assistant herb; it is incompatible with Peony Root (Mu Dan Pi), Magnetite (Xuan Shi), and Ophiopogon Tuber (Mu Meng); it fears Amethyst (Zi Shi Ying) and [Certain] Grass.)
It first appeared in Shixing, but is also found in stone caves of famous mountains in Jiangling and the eastern regions. Only those that are hollow, thin as goose quills, break like fingernails, lack the texture of goose teeth in the center, and possess a bright luster are considered superior. Some long specimens reach one or two chi in length. They are yellow in color and turn white when washed with vinegar (Ku Jiu). The *Immortal Classics* rarely use it. However, it is highly valued in secular medical formulas and is very expensive. (From *Xinxiu Bencao*, p. 15; *Daguan Bencao*, Vol. 3; *Zhenghe Bencao*, p. 83)
