气味：苦，平，寒，有毒。主治：寒热往来、鼠瘰（颈部淋巴结结核）、恶疮、疽、痔、死肌（坏死的肌肉组织），能杀灭精怪邪鬼，驱除各种邪气和百虫毒，抵御兵器伤害，炼制后服用可轻身成仙。
（《名医别录》记载：雄黄产于武都山谷的煌山南面。武都是氏人和羌人的居住地，称为仇池，后来名为阶州，地处西戎边界。宕昌也产雄黄，但品质稍差。煌山位于凉州以西数千里处。近来使用的石门雄黄被称为新坑，是刚开始开采的优质石黄。阶州又出产一种水窟雄黄，生长在山岩中有水流的地方，颜色深红略带紫色，质地极轻虚，药效最为显著。抱朴子说：雄黄应当选用武都山中出产的纯净无杂质的，形状像丹砂一样，红得像鸡冠，光彩明亮的才能使用。有青黑色且坚硬的，名叫熏黄。有颜色形状像真品但气味臭的，名叫臭黄，这两种都不用于内服，只能用来治疗疮疥。金刚钻生长在雄黄矿中，孕妇佩戴雄黄，能使女子转为男子。）
雄黄色黄质坚，形状如丹砂，光泽闪烁，这是禀受了土和金的气化作用，属于疏散阴邪、解除毒素的药物。水毒上行，则导致身体寒热交替，以及颈部出现鼠瘰。雄黄禀受土气而克制水毒，所以能治疗此症。肝血壅滞，则产生恶疮并发展为疽和痔，雄黄禀受金气而平抑肝木，所以能治疗此症。死肌是指肌肤麻木不仁，精怪恶鬼属于阴类邪气，雄黄禀受火气而光明，所以能治疗死肌，杀灭精怪恶鬼。各种邪气和百虫之毒，遇到土气就能化解，雄黄色黄属土，所以能杀灭百虫毒。所谓“胜五兵”，就像硫黄能熔化金银铜铁锡一样。“五兵”指五金（金、银、铜、铁、锡），“胜五兵”意味着火气旺盛。经过炼制后服用，能将刚硬转化为柔和，金光内敛，所以能轻身成仙。
Taste and Nature: Bitter, neutral, cold, toxic. Indications: Alternating chills and fever (Hanre Wanglai), scrofula (Shuluo - tuberculous lymphadenitis of the neck), malignant sores, carbuncles, hemorrhoids, necrotic muscle tissue (Simi). It can kill spirits and evil ghosts, dispel various pathogenic factors and insect poisons, withstand weapons, and when refined and ingested, it can lighten the body and lead to immortality.
(The *Bielu* states: Realgar is produced in the valleys of Mount Huang in Wudu. Wudu was inhabited by the Di and Qiang tribes, known as Qiuchi, later named Jiazhou, bordering the Western Rong regions. Dangchang also produces realgar, but of slightly inferior quality. Mount Huang is located thousands of li west of Liangzhou. Recently, realgar from Shimen is called "New Pit," representing the newly exploited high-quality stone yellow. Jiazhou also produces a type of "water cave realgar," which grows in mountain rocks where water flows; its color is deep red with a slight purple tint, its texture is extremely light and porous, and its efficacy is supreme. *Baopuzi* states: Realgar should be obtained from pure, unadulterated sources in the mountains of Wudu, shaped like cinnabar, red as a rooster's comb, and shining brightly; only this kind is usable. Those that are dark green-black and hard are called Xunhuang (Smoked Yellow). Those that resemble the genuine product in color and shape but have an offensive odor are called Chouhuang (Stinking Yellow); neither is used for internal administration but only for treating sores and scabies. Diamond crystals grow within realgar deposits; if pregnant women wear realgar, it can transform females into males.)
Realgar has a yellow color and firm texture, resembling cinnabar, with a shimmering luster. It embodies the qi transformation of Earth and Metal, serving as a herb that disperses yin pathogens and resolves toxicity. When water toxicity ascends, it causes alternating chills and fever and cervical scrofula. Realgar, embodying Earth qi, overcomes water toxicity, thus treating these conditions. When liver blood becomes stagnant, it generates malignant sores leading to carbuncles and hemorrhoids. Realgar, embodying Metal qi, pacifies the Liver, thus treating these conditions. Necrotic muscle tissue refers to insensate skin and flesh. Spirits and evil ghosts belong to yin-type pathogens. Realgar, embodying Fire qi and possessing brightness, treats necrotic muscle tissue and kills spirits and evil ghosts. Various pathogenic factors and insect poisons are resolved upon encountering Earth qi. Since Realgar is yellow and belongs to Earth, it kills insect poisons. The phrase "withstands five weapons" is analogous to how Sulfur can melt gold, silver, copper, iron, and tin. "Five weapons" refers to the five metals (gold, silver, copper, iron, tin). "Withstanding five weapons" implies abundant Fire qi. After refining and ingestion, rigidity transforms into flexibility, and golden light is stored inwardly, thus lightening the body and achieving immortality.
