为左顾。”此物本无目，如此，焉得更有顾盼也。

必须将牡蛎烧制成粉末使用，同时与麻黄根等量混合捣碎，研磨成极细的粉末。治疗盗汗和阴汗时，本方（指前文提到的方剂）主张使用生品，这是遵循了本方的原意。医经中原本没有这种说法，只是听从了陶隐居（陶弘景）的观点。《西阳杂俎》一书中已经指出：“牡蛎称为‘牡’，并不是因为它是雄性的。就像牡丹花，难道还有‘牝丹’（雌性牡丹）吗？现在的做法是配合地气，人面向午位（南方），让牡蛎的顶端朝向子位（北方），观察它的口部，如果口在左边，就称为‘左顾’。”但这东西本来就没有眼睛，这样怎么能说有顾盼（看）的动作呢？
自己采集的是真品，市场上出售的，恐怕不全是桑树上的。《蜀本·图经》中的浸泡方法，不如稍微蒸过后再使用为好。邻居有一个男子，每天小便几十次，尿液像浓米泔水一样，颜色也白，心神恍惚，身体消瘦憔悴，食欲减退，这是因房劳过度导致的。让他服用桑螵蛸散，还没服完一剂就好了。此方能安神魂，定心志，治疗健忘、小便频数，补益心气。配方为：桑螵蛸、远志、石菖蒲、龙骨、人参、茯神、当归、龟甲（醋炙），以上各一两，研为末。夜间睡觉前，用人参汤调服二钱。如果没有桑树上的桑螵蛸，就用其他的，但仍需加入炙过的桑白皮作为辅助，用量视情况而定。大概是因为桑白皮能利水，用意在于引导桑螵蛸进入肾经。使用桑螵蛸的意思就是这样，然而治疗男女虚损，益精，阳痿，梦遗滑精，遗尿，疝气瘕块，小便白浊，肾衰等症状，是不可缺少的。
陈藏器的说法是正确的，现在海中没有大雁，怎么会有吃蛤蜊粪便排出的情况呢？如果蛤壳里还有肉的时候，还可以食用。肉既然没有了，哪里还会有经过粪便过滤出这么多（指形状像粪便）的呢？必定是因为它们都没有棱角，所以才有了这种说法。殊不知这是因为风浪日夜冲刷淘汰，所以才会变成这样。治疗伤寒出汗不止，手脚抽搐，用海蛤、川乌头各一两，穿山甲二两，研为末，用酒糊制作成丸药，大小约一寸，捏扁，放在患处的脚心下，用葱白覆盖药物，用布带缠紧。在温暖的房间里用热水浸脚至膝盖以上，时间久了水温降低，再添加热水，等到全身出汗为止。一般每隔一二天浸脚一次，以见效为度。
Oyster shell (Muli, 牡蛎) must be calcined into powder. It is also mixed in equal parts with the root of Ephedra (Mahuanggen, 麻黄根), pounded and ground into an extremely fine powder. For spontaneous sweating (Zi Han, 自汗) and nocturnal sweating (Dao Han, 盗汗), as well as sweating in the genital area (Yin Han, 阴汗), this formula advocates using the raw form, adhering to the original intent of the formula. The medical classics do not originally mention this; it follows only the statement of Tao Hongjing (Tao Yinju, 陶隐居). *Xiyang Zazu* already stated: "The term 'male' (Mu, 牡) in Oyster shell does not refer to its masculinity. Just like Peony flower (Mudan, 牡丹), how could there be a 'female peony'? The current practice aligns with Earth energy: the person faces the Wu position (South), with the apex of the Oyster shell pointing to the Zi position (North). Observing its mouth, if the mouth is on the left, it is called 'Left-Gazing' (Zuogu, 左顾)." However, this creature naturally has no eyes; thus, how can it have gazing movements?
Those collected personally are authentic. Those sold in the market may not all be from mulberry trees. The soaking method described in *Shuben Tujing* is inferior to steaming them slightly before use. A neighbor suffered from urinary frequency, urinating dozens of times a day, with urine resembling thick rice wash water, white in color. He experienced mental confusion, emaciation, and loss of appetite, caused by sexual exhaustion. I prescribed Sangpiaoxiao San (Mulberry Mantis Egg Case Powder) for him, and he recovered before finishing one dose. This formula calms the spirit (An Shenhun, 安神魂), stabilizes willpower (Ding Xinzi, 定心志), treats forgetfulness (Jianwang, 健忘) and urinary frequency, and tonifies Heart Qi (Bu Xinqi, 补心气). Ingredients: Mulberry Mantis Egg Case (Sangpiaoxiao, 桑螵蛸), Polygala Root (Yuanzhi, 远志), Acorus Rhizome (Changpu, 菖蒲), Dragon Bone (Longgu, 龙骨), Ginseng (Renshen, 人参), Poria with Hostwood (Fushen, 茯神), Angelica Sinensis Root (Danggui, 当归), and Tortoise Shell (Guijia, 龟甲) stir-fried with vinegar. Each ingredient is used in 1 liang. Grind into powder. At night, take 2 qian with Ginseng decoction. If mulberry-based egg cases are unavailable, others may be used, but roasted Mulberry Root Bark (Sangbaipi, 桑白皮) should still be added as an adjunct, in appropriate proportions. The rationale is that Mulberry Root Bark promotes diuresis, intended to guide the Mantis Egg Case into the Kidney Meridian. Such is the intention behind using Sangpiaoxiao. Nevertheless, for treating deficiency syndromes in men and women, benefiting essence, impotence (Yinwei, 阴痿), seminal emission during dreams (Meng Shijing, 梦失精), enuresis (Yiniao, 遗溺), hernia masses (Shanjia, 疝瘕), turbid white urine (Xiaobai Zhuo, 小便白浊), and Kidney decline, it is indispensable.
Chen Cangqi's statement is correct. Since wild geese do not exist in the sea now, how could they excrete clam feces? Clams are edible only when flesh is present inside the shell. If the flesh is gone, how could there be so much material filtered through feces? This theory likely arose because these clams lack sharp edges. In fact, this is due to the daily washing and erosion by wind and waves. To treat cold damage (Shanghan, 伤寒) with profuse sweating and spasms of the limbs, use Sea Clam (Hai Ge, 海蛤) and Sichuan Aconite Root (Chuan Wutou, 川乌头), each 1 liang, and Pangolin Scales (Chuanshanjia, 穿山甲), 2 liang. Grind into powder, mix with wine paste to make pills about 1 cun in size, flatten them, and place under the sole of the affected foot. Cover the medicine with scallion whites and bind tightly with cloth. Soak the feet in hot water up to the knees in a warm room. As the water cools, add more hot water, until the whole body sweats. Soak feet once every one or two days, stopping when effective.
