退肺胃之火邪。清暑除烦能止渴。解阳明之郁热。祛温逐疫可消斑。性属甘寒。质颇
重镇。（石膏大寒质重。味甘之物。直清肺胃。相传解肌之说。皆因表有风寒。里有郁热。
故正气被郁。不得透达于表。郁热解则表里通矣。大青龙之制。亦犹是耳。岂质重性寒味甘
之品而能发汗者哉。）

甘淡性寒。清热有功于肺胃。分消质滑。导邪直降于州都。除湿热之稽留。宣表里而
无滞。（滑石其性寒。其体滑。其质重。沉降下行。祛湿热。从小肠膀胱而出。有谓其燥者。
亦湿去则燥之故。非滑石之性燥也。或谓其能解肌者。亦里通而表解之意欤。）

石膏：能清除肺和胃的火热邪气。清解暑热、消除烦闷并能止渴。解除阳明经的郁结之热，祛除温病疫毒，可消除斑疹。药性属于甘寒，质地相当沉重具有镇降作用。（石膏大寒且质地重，味甘的药物，直接清泄肺胃之火。相传的“解肌”说法，都是因为体表有风寒，体内有郁热，导致正气被郁闭，不能透达于体表。当体内的郁热解除后，表里之气便通畅了。大青龙汤的组方原理也是基于此。难道质地重、性寒、味甘的药物能够发汗吗？）
滑石：味甘淡，性寒，对清泄肺胃的热邪有功。因其质地滑利，能分消湿热，引导邪气直接下降至膀胱（州都）。除湿热的滞留，宣通表里而无阻滞。（滑石性质寒凉，体质滑利，质地沉重，沉降下行。祛除湿热，从小肠和膀胱排出。有人说它燥湿，也是因为湿气去除后显得干燥的缘故，并非滑石本性燥烈。有人说它能解肌，大概也是指里气通畅则表证自解的意思吧。）
赤石脂：固摄大肠，治疗久痢导致的便血（肠红），治疗崩漏和带下淋漓不尽。味甘酸，温补肾肾，滋养心气，调和营血并收敛血液。外涂可治疗癞风引起的皮肤溃烂，敷贴可促进肌肉生长。（赤石脂这种石头性质最粘腻且有油脂感，用来固护根本非常良好。它的味甘酸，质地沉重镇降。凡是用药治病，都应该观察其形态色泽，揣度其性味，审察其寒温属性，自然能达到得心应手的妙境，不必拘泥于本草的各种说法。总之，它的治疗作用主要入心、肾、大肠及血分，功效不外乎固涩和重镇，足以概括其特点。）
炉甘石：得金银矿的气化而结成，能进入阳明经专门燥湿。用三黄煎水来冶炼，善于治疗眼疾并可平抑肝阳。止血生肌，味甘温，无毒。（炉甘石出产于金银矿中，是金银的苗裔。舔舐时也会粘舌，因为它得到了金银之气，所以能平肝，治疗一切眼疾。用三黄煎水冶炼使用，长于外用治疗，没有内服的方法罢了。）
Shigao (Gypsum Fibrosum): Clears fire-evil from the Lung and Stomach. Clears summerheat, relieves irritability, and can quench thirst. Resolves stagnant heat in the Yangming channel; dispels warm pathogens and epidemics, and can eliminate macules. Its nature is sweet and cold; its substance is quite heavy and sedating. (Gypsum is greatly cold and heavy in substance, with a sweet taste, directly clearing the Lung and Stomach. The passed-down theory of "releasing the muscle layer" arises because when exterior wind-cold coexists with interior stagnant heat, the healthy Qi is constrained and cannot penetrate to the exterior. Once the interior stagnant heat is resolved, the interior and exterior become unobstructed. The formulation principle of Da Qing Long Tang is also based on this. How could a substance that is heavy, cold in nature, and sweet in taste induce sweating?)
Huashi (Talcum): Sweet and bland in taste, cold in nature; it benefits the Lung and Stomach by clearing heat. Due to its slippery quality, it separates and eliminates dampness, guiding evil downwards directly to the Bladder (Zhou Du). It removes lingering damp-heat and unblocks the interior and exterior without stagnation. (Talcum is cold in nature, slippery in texture, and heavy in substance, descending and sinking. It expels damp-heat via the Small Intestine and Bladder. Some say it dries dampness, but this is merely the result after dampness is removed, not an inherent drying property of Talcum. Others suggest it releases the muscle layer, likely meaning that when the interior is unobstructed, the exterior condition resolves.)
Chishizhi (Halloysitum Rubrum): Secures the Large Intestine; treats chronic dysentery with intestinal bleeding (red blood in stool); treats metrorrhagia and leukorrhea dripping continuously. Sweet and sour in taste, warms the Kidney, nourishes Heart Qi, harmonizes Ying (Nutritive) Blood, and astringes blood. Applied externally, it treats ulceration caused by Leprosy-like skin diseases; applied as a dressing, it promotes tissue regeneration. (This stone of Halloysitum Rubrum is extremely sticky and oily, making it excellent for securing the foundation. Its taste is sweet and sour, and its substance is heavy and sedating. In treating diseases with herbs, one should observe form and color, assess nature and flavor, and examine cold or warmth properties, thereby achieving mastery without being bound by various theories in Materia Medica. In short, its therapeutic action enters the Heart, Kidney, Large Intestine, and Blood aspect; its efficacy lies primarily in astringency and heavy sedation, which suffices to summarize it.)
Luganshi (Calamina): Formed by obtaining the Qi of gold and silver ores; enters the Yangming channel specifically to dry dampness. Smelted using decoction of San Huang (Three Yellows); excels in treating eye diseases and pacifying Liver Yang. Stops bleeding and generates flesh; sweet and warm in nature, non-toxic. (Calamina originates from gold and silver mines; it is the sprout of gold and silver. It sticks to the tongue when licked. Because it obtains the Qi of gold and silver, it can pacify the Liver and treat all eye diseases. Used after smelting with San Huang decoction, it is superior for external treatment, with no recorded method for internal use.)
