（《拾遗》）
【释名】雷楔。
时珍曰∶旧作针及屑，误矣。
【集解】藏器曰∶此物伺候震处，掘地三尺得之。其形非一，有似斧刀者，锉刀者，有
安二孔者。一云出雷州，并河东山泽间，因雷震后得者。多似斧色，青黑斑纹，至硬如玉。
或言是人间石造，纳与天曹，不知事实。
时珍曰∶按∶《雷书》云∶雷斧如斧，铜铁为之。雷 似 ，乃石也，紫黑色。雷锤重
数斤，雷钻长尺余，皆如钢铁，雷神以劈物击物者。雷环如玉环，乃雷神所 遗落者。雷珠
乃神龙所含遗下者，夜光满室。又《博物志》云∶人间往往见细石形如小斧，名霹雳斧，一
名霹雳楔。《玄中记》云∶玉门之西有一国，山上立庙，国人年年出钻，以给雷用。此谬言
也。雷虽阴阳二气激薄有声，实有神物司之，故亦随万物启蛰，斧、钻、 、锤皆实物也
。若曰在天成象，在地成形，如星陨为石。则雨金石、雨粟麦、雨毛血及诸异物者，亦在地
成形者乎？必太虚中有神物使然也。陈时苏绍雷锤重九斤。宋时沈括于震木之下得雷楔，似
斧而无孔。鬼神之道幽微，诚不可究极。
【气味】无毒。
【主治】大惊失心，恍惚不识人，并石淋，磨汁服，亦煮服。作枕，除魔梦不祥（藏器）。
刮末服，主瘵疾，杀劳虫，下蛊毒，止泄泻。置箱 间，不生蛀虫。诸雷物佩之，安神定志，
治惊邪之疾（时珍。出《雷书》）。

【释名】雷楔。
李时珍说：旧本写作“针”和“屑”，是错误的。
【集解】藏器说：这种物品在雷电发生处守候，挖掘地下三尺即可得到。它的形状不一，有的像斧头、刀，有的像锉刀，有的安有两个孔。一种说法是出产于雷州，以及河东的山泽之间，是在雷击之后得到的。大多颜色像斧头，呈青黑色斑纹，质地坚硬如玉石。有人说这是人间制造的石头，献给天曹（天庭），不知事实如何。
李时珍说：查考《雷书》记载：雷斧像斧头，由铜铁制成。雷钻似凿子，是石头做的，紫黑色。雷锤重几斤，雷钻长一尺多，都像钢铁一样，是雷神用来劈打物体的工具。雷环像玉环，是雷神遗失落下的。雷珠是神龙口中含住后遗留下的，夜间光芒充满房间。又据《博物志》记载：人间常常见到细小的石头形状像小斧头，名叫霹雳斧，又名霹雳楔。《玄中记》记载：玉门以西有一个国家，山上建有庙宇，国人每年外出开采钻具，以供雷神使用。这是荒谬的言论。雷虽然是阴阳二气激荡摩擦发出的声音，实际上有神灵主宰它，所以也随着万物苏醒（惊蛰时节）而变化，斧、钻、凿、锤都是实物。如果说在天形成景象，在地形成形状，比如流星坠落变成石头。那么下雨时落下金石、粟麦、毛发血液以及各种异物，也是在地形成形状的吗？必定是太虚（天空/宇宙）中有神灵使它们这样。陈朝时苏绍的雷锤重九斤。宋朝时沈括在震倒的树木下得到雷楔，像斧头但没有孔。鬼神之道幽深微妙，确实无法穷尽探究。
【气味】无毒。
【主治】受大惊导致的心神失守，精神恍惚不认识人，以及石淋（泌尿系结石），磨成汁服用，也可以煮服。做成枕头，可以消除魔梦和不祥之兆（藏器）。刮成粉末服用，主治痨病（肺结核等慢性消耗性疾病），杀灭劳虫（寄生虫），排出蛊毒，止住泄泻。放在箱子柜间，不生蛀虫。佩戴各种雷物，可以安神定志，治疗惊邪类疾病（李时珍。出自《雷书》）。
(From *Bencao Shiyi* [Supplement to Materia Medica])
[Names] Lei Xi (Thunder Wedge).
Li Shizhen stated: The old texts wrote it as "Zhen" [Needle] and "Xie" [Dregs], which was incorrect.
[Collection and Explanation] Zang Qi said: This object is sought after where lightning strikes; digging three chi underground will reveal it. Its shape varies; some resemble axes or knives, others resemble files, and some have two holes installed. One account states it originates from Leizhou and the mountainous and marshy areas of Hedong, obtained after a thunderstorm. It mostly resembles an axe in color, with dark green and black mottling, and is hard as jade. Some say it is stone manufactured by humans and offered to the Heavenly Court (Tian Cao), but the facts are unknown.
Li Shizhen stated: According to *Lei Shu* [Book of Thunder]: The Lei Fu [Thunder Axe] resembles an axe and is made of copper or iron. The Lei Zuan [Thunder Drill] resembles a chisel and is made of stone, purple-black in color. The Lei Chui [Thunder Hammer] weighs several jin, and the Lei Zuan is over one chi long; both are like steel, used by the Thunder God to split or strike objects. The Lei Huan [Thunder Ring] resembles a jade ring and was dropped by the Thunder God. The Lei Zhu [Thunder Pearl] was spat out by divine dragons and left behind, emitting light that fills the room at night. Furthermore, *Bowuzhi* [Inquiries into Various Things] records that small stones resembling small axes are often seen in the human world, named Pili Fu [Thunderbolt Axe], also known as Pili Xi [Thunderbolt Wedge]. *Xuanzhongji* [Record of the Mysterious Middle] claims there is a country west of Yumen Pass with a temple on a mountain, where people annually mine drills for the use of the Thunder God. This is absurd talk. Although thunder is the sound generated by the friction and collision of Yin and Yang energies, it is actually governed by divine entities. Therefore, it coincides with the awakening of all things during Jingzhe [Awakening of Insects solar term]; the axes, drills, chisels, and hammers are all physical objects. If one argues that phenomena form in heaven and shapes form on earth, such as meteorites falling as stones, then do metallic stones, millet, wheat, hair, blood, and other strange items falling during rain also form shapes on earth? It must be that divine entities in the Great Void [Tai Xu] cause this. During the Chen dynasty, Su Dao's Lei Chui weighed nine jin. During the Song dynasty, Shen Kuo found a Lei Xi under a tree struck by lightning, resembling an axe but without a hole. The way of ghosts and gods is profound and subtle, truly unfathomable.
[Flavor and Toxicity] Non-toxic.
[Therapeutic Actions] Treats sudden fright causing loss of heart-mind control, mental confusion where one does not recognize people, and Shi Lin [Stone Strangury / Urinary Calculus]. Grind into juice and ingest, or boil and drink. Make into a pillow to eliminate demonic dreams and inauspicious omens (Zang Qi). Scrape into powder and ingest to treat Zhai Ji [Consumption Disease / Tuberculosis], kill Lao Chong [Labor Worms / Parasites], expel Gu Du [Gu Poison], and stop diarrhea. Place between chests or cabinets to prevent insect infestation. Wearing various Lei Wu [Thunder Objects] calms the spirit and stabilizes the will, treating diseases caused by fright and evil influences (Li Shizhen. From *Lei Shu*).
