【鳖甲】
气性平。味咸。无毒。主治心腹部的症积和瘕聚。消除坚硬的积聚以及寒热症状。去除痞块、息肉、阴部蚀烂、痔核及恶肉。（用醋炙制）
鳖甲气性平，禀受自然界秋季收敛的金气，归入手太阴肺经。味咸且无毒，获得大地北方水的味道，归入足少阴肾经。
气味都主沉降，属于阴。心腹部是厥阴肝经循行的部位。积聚而有形体可查证的称为“症”，假借外物而成的称为“瘕”。坚硬的积聚导致寒热发作，是因为厥阴肝气凝聚，亢盛到了极点。鳖甲气性平入肺，肺气平和可以制约肝木；味咸可以软化坚硬之物，所以能主治这些病症。痞证是肝气阻滞所致，咸平之性能制约肝气并软化坚硬，所以也能主治。息肉、阴部蚀烂、痔疮及恶肉，一种生于鼻部，鼻是肺的窍道；一种生于大小便处，二便是肾的窍道。鳖甲入肺肾二经以软化坚硬，所以能消除一切恶肉。
配方：
鳖甲同牛膝、当归、陈皮、首乌、知母、麦冬配伍，治疗久疟。同知母、石膏、麦冬、贝母、竹叶配伍，治疗温疟。同青蒿、麦冬、五味子、生地、枸杞子、牛膝配伍，治疗骨蒸劳热。

龟甲气性平，禀受自然界秋季收敛的金气，归入手太阴肺经。味甘，获得大地中正的土味，归入足太阴脾经。它是北方的神物，介虫之长，性质复归有毒，禀受阴寒之性，归入足少阴肾经。其气味降多于升，属于阴。脾统摄血液，若脾血不能统摄，则出现漏下赤白的症状。龟甲主治此症，是因为味甘能补益脾气。疟疾发展到出现症积瘕聚，说明湿热邪气已经牢固结聚在阴分。龟甲阴寒可以清热，气性平可以利湿，所以能主治此症。火邪结于大肠，则生五种痔疮；湿浊下行灌注，则患阴部蚀烂。肺与大肠相表里，肾主阴户，龟甲性寒可去热，气平可消湿，所以能主治此症。脾主四肢，湿气胜则四肢沉重虚弱，龟甲味甘能补益脾气，性平能祛除湿邪，湿气行散，四肢就能强健。肾主骨，小儿肾虚，则囟门骨骼不合，龟甲主治此症，是因为能补肾阴。长期服用能益肾，肾是胃的关口，关口通利，能去除脾湿，所以身体轻健且不感饥饿。

[Chelonae Carapax et Plastrum]
Qi is neutral. Flavor is salty. Non-toxic. Primarily treats abdominal masses and growths (Zheng and Jia), hard accumulations with alternating chills and fever, removes痞 (obstructions), polyps, genital ulcers, hemorrhoidal nodes, and malignant flesh. (Processed with vinegar).
Chelonae Carapax et Plastrum has a neutral Qi, inheriting the metal energy of autumnal gathering from heaven, entering the Hand Taiyin Lung Meridian. Its salty flavor and non-toxic nature derive from the water essence of the north on earth, entering the Foot Shaoyin Kidney Meridian.
Both Qi and flavor descend, belonging to Yin. The abdomen and chest are the pathways of the Foot Jueyin Liver Meridian. Accumulations that have form and can be palpated are called Zheng (masses); those formed by external factors are called Jia (growths). Hard accumulations causing chills and fever result from the stagnation and excessive hyperactivity of Jueyin Liver Qi. Chelonae Carapax et Plastrum enters the Lung via its neutral Qi; Lung Qi in balance can control Liver Wood. Its salty flavor softens hardness, thus treating these conditions. Pi (obstruction) is caused by stagnant Liver Qi; the salty and neutral properties control Liver Qi and soften hardness, hence it also treats this. Polyps, genital ulcers, hemorrhoids, and malignant flesh arise either in the nose (the orifice of the Lung) or in the bowels and urethra (the orifices of the Kidney). Entering the Lung and Kidney meridians to soften hardness, it eliminates all malignant flesh.
Prescriptions:

Combined with Anemarrhenae Rhizoma (Zhimu), Gypsum Fibrosum (Shigao), Ophiopogonis Radix (Maidong), Fritillariae Cirrhosae Bulbus (Beimu), and Bambusae Folium (Zhuye) treats warm malaria. Combined with Artemisiae Annuae Herba (Qinghao), Ophiopogonis Radix (Maidong), Schisandrae Fructus (Wuweizi), Rehmanniae Radix (Shengdi), Lycii Fructus (Gouqi), and Achyranthis Bidentatae Radix (Niuxi) treats bone-steaming consumption.
[Cryptotestudinis Carapax et Plastrum]
Qi is neutral. Flavor is sweet. Toxic. Primarily treats leukorrhea with blood (Lou Xia Chi Bai), breaks up masses and growths, treats malaria, five types of hemorrhoids, genital ulcers, damp-bi syndrome, heaviness and weakness of the four limbs, and unclosed fontanelles in children. Long-term use makes the body light and reduces hunger.
Cryptotestudinis Carapax et Plastrum has a neutral Qi, inheriting the metal energy of autumnal gathering from heaven, entering the Hand Taiyin Lung Meridian. Its sweet flavor derives from the central earth essence on earth, entering the Foot Taiyin Spleen Meridian. It is the deity of the North, the leader of shelled creatures, possessing a complex toxicity and inheriting Yin-cold nature, entering the Foot Shaoyin Kidney Meridian. Its Qi and flavor descend more than they ascend, belonging to Yin. The Spleen governs blood; if Spleen blood fails to govern, leukorrhea with blood occurs. Cryptotestudinis Carapax et Plastrum treats this because its sweet flavor tonifies the Spleen. When malaria progresses to form masses and growths, damp-heat pathogens have firmly consolidated in the Yin aspect. Cryptotestudinis Carapax et Plastrum clears heat via its Yin-cold nature and promotes diuresis via its neutral Qi, thus treating this condition. Fire consolidating in the Large Intestine generates five types of hemorrhoids; turbid dampness pouring downward causes genital ulcers. The Lung connects with the Large Intestine, and the Kidney governs the yin organs. Its cold nature removes heat, and its neutral Qi dissipates dampness, thus treating these conditions. The Spleen governs the four limbs; excess dampness causes heaviness and weakness. Cryptotestudinis Carapax et Plastrum tonifies the Spleen via its sweet flavor and dispels dampness via its neutral nature; when dampness moves, the four limbs become strong. The Kidney governs bones; Kidney deficiency in children leads to unclosed fontanelles. Cryptotestudinis Carapax et Plastrum treats this by tonifying Kidney Yin. Long-term use benefits the Kidney. The Kidney is the gate of the Stomach; when the gate is open, it removes Spleen dampness, resulting in a light body and reduced hunger.
Prescriptions:
Cryptotestudinis Carapax et Plastrum combined with Rehmanniae Radix Preparata (Shudi), Phellodendri Cortex (Huangbai), Anemarrhenae Rhizoma (Zhimu), and Porcine Spinal Cord (Zhujingui) made into pills, named Buyin Wan (Tonify Yin Pill), treats Yin deficiency with flourishing ministerial fire. Combined with Fa Hui (burned hair/scalp ash), Chuanxiong Rhizoma (Chuanxiong), and Angelicae Sinensis Radix (Guishen) treats difficult labor and unclosed pubic symphysis in short-statured women.
