玳瑁，又名玳瑁，属于龟类动物。它汲取了水中至阴之气，因此药性寒凉且无毒，能够解除各种热毒，其灵性极强。凡是遇到饮食中的蛊毒等情况，玳瑁的身体必定会自行摇动。然而必须使用活体才具有灵性，死去的则无效。被蛊毒所伤的人，可以刺取活玳瑁的血饮用，或者将活体研磨成浓汁服用，即可立即解毒。玳瑁主治心风惊痫（因心受风邪引起的惊厥癫痫）。它能解除烦热，通行气血，破除症结（腹内结块），消除痈肿，通利大小肠。这是因为它禀赋纯阴之性，气味极寒，所以能治疗上述疾病，对于解痘毒也有神效。凡是遇到流行性痘疹病症，在痘疮未发出时服用可使之内消，已发出时可使痘疮稀少。用法是用生玳瑁和生犀角各研磨成浓汁一合，混合均匀后温服半合，每日三次效果最佳。如果痘疮颜色黑陷，这是因为心热血凝所致。按照此方再加入少许猪心血、五匙紫草汁，混合均匀后温服。
珍珠是由太阴精气凝结而成，所以中秋没有月亮的时候蚌胎就不形成，因此其功效多作用于阴经。它的色泽光明，质地坚硬，大小不一，以新鲜完整未经钻孔缀饰的为上品。味道微咸，气性寒凉，无毒。归入手少阴心经和足厥阴肝经。心虚有热，会导致神气浮越；肝虚有热，会导致眼睛生翳障。珍珠能清除这两条经络的热邪，所以能镇心安神、明目。耳聋本属于肾虚有热，珍珠味甘性寒，所以主治此症。所谓“逆肺”，是指胪胀（皮肤肿胀）。胸腹气逆胀满，以及手足皮肤都发生肿胀。《内经》说：“各种湿邪导致的肿胀满闷都属于脾土。”各种腹部胀大，都属于热证。这是脾虚有热，兼有积滞所致。珍珠味甘，既能补益脾气（原文作益脾寒，疑为笔误或特定语境，此处依理译为补益脾气/健脾），又能除热软坚，还能磨积消滞，所以也主治此症。珍珠藏在沼泽中，河流山川自然显得妩媚动人，何况涂抹在脸上，难道不能让人面色润泽吗？至于疔毒痈肿，促进肌肉生长、愈合伤口，尤其达到奇效。但珍珠质地最坚硬，必须研磨得像飞面一样细，才可以食用，否则内服会损伤脏腑，外敷会使肌肉疼痛。蛤蚌没有阴阳雌雄之分，需要依靠雀鸟变化孵化，所以珍珠专一于阴精。
珍珠的功效是：镇安心神，清泻肝热，治疗手足皮肤肿胀，小儿风热惊痫，用绵布包裹塞入耳道治耳聋，敷面使皮肤润泽，坠痰止渴，去除眼翳明目，生肌收口。蚌即珠母，其肉的功能是醒酒，去热除烦。
Dai Mao (Trionyx sinensis shell), also known as Dai Mao, belongs to the turtle family. It absorbs the most Yin Qi of water, thus having a cold nature and being non-toxic, capable of resolving all kinds of heat toxins, with its nature being extremely spiritual. Whenever it encounters food-related Gu poison (parasitic poisoning), its body will inevitably shake spontaneously. However, only living specimens are effective; dead ones lose this efficacy. For those poisoned by Gu, blood from a live Dai Mao can be extracted and drunk, or a thick juice made from grinding a live specimen can be taken for immediate relief. Dai Mao treats Xin Feng Jing Xian (convulsions and epilepsy caused by wind affecting the Heart). It resolves irritability and heat, promotes the flow of Qi and Blood, breaks up accumulations (masses in the abdomen), dissipates carbuncles and swellings, and unblocks the large and small intestines. This is because its nature is purely Yin and its flavor and aroma are extremely cold, enabling it to treat such conditions. It is also highly effective in resolving pox toxins. In cases of epidemic pox diseases, taking this herb before the eruption helps resolve it internally, and after eruption reduces the number of lesions. The method involves grinding raw Dai Mao and raw Xi Jiao (Rhinoceros Horn) into thick juices, mixing them evenly, and taking half a he (a traditional unit of volume) warm, three times a day, which is optimal. If the pox lesions are black and sunken, it indicates Heat in the Heart and congealed Blood. To this formula, add a small amount of Zhu Xin Xue (Pig Heart Blood) and five spoons of Zi Cao Zhi (Gardenia Juice/Gromwell Juice), mix well, and take warm.
Zhen Zhu (Pearl) is formed from the essence of Tai Yin (Great Yin). Therefore, when there is no moon in mid-autumn, clams do not form pearls. Its functions mostly enter the Yin meridians. Its color is bright, its texture is hard, and its size varies. The best quality is fresh, complete, and unperforated. Its taste is slightly salty, its nature is cold, and it is non-toxic. It enters the Hand Shaoyin (Heart) and Foot Jueyin (Liver) meridians. When the Heart is deficient and has Heat, Shen Qi (Spiritual Energy) floats and escapes; when the Liver is deficient and has Heat, visual obstructions (cataracts/macular degeneration) form. By clearing Heat from these two meridians, it can calm the Heart and brighten the eyes. Deafness originally belongs to Kidney deficiency with Heat; since Pearl is sweet and cold, it treats this condition. "Reversing the Lung" refers to Lu Zhang (skin edema/swelling). There is rebellious Qi causing distension and fullness in the chest and abdomen, and swelling of the skin on the hands, feet, and body. The Classic states: "All dampness-induced swelling and fullness belong to Spleen Earth." All abdominal distensions and enlargements belong to Heat. This is caused by Spleen deficiency with Heat combined with stagnation. Pearl is sweet in taste; it can tonify the Spleen, clear Heat, soften hardness, grind away accumulations, and eliminate stagnation, thus also treating this condition. When Pearl resides in marshes, rivers and mountains naturally become charming; how much more so when applied to the face, making the complexion lustrous? Regarding Ding Du (carbuncles) and Yong Zhong (abscesses), promoting flesh growth and healing wounds achieves miraculous effects. However, Pearl is extremely hard and must be ground into a fine powder like flour to be edible; otherwise, internal use damages the Zang-Fu organs, and external application causes muscle pain. Clams have no Yin-Yang male-female distinction and require magpie transformation for hatching; thus, Pearl specializes in Yin Essence.
Pearl calms the Spirit, cools Liver Heat, treats skin swelling on hands and feet, pediatric Wind-Heat convulsions, is wrapped in cotton and inserted into the ear to treat deafness, applied to the face to make skin lustrous, descends Phlegm, stops thirst, removes visual obstructions, brightens the eyes, generates flesh, and closes wounds. Bang (Clam) is the mother of Pearl; its meat functions to sober up intoxication, remove Heat, and relieve irritability.
Main Indications (Integration of Pox and Rash): Pearl, finely ground into powder, treats pediatric convulsive heat, calms the Heart, and brightens the eyes. For Ding Du and Yong Du within pox lesions, it is mixed into topical medications for miraculous effects.
