味咸，寒，有小毒。主五癃邪结气，破石淋，下血，利小便水道。一名蜥蜴，一名山龙
子，一名守宫，一名石蜴。
生平阳川谷，及荆山石间。五月取，着石上令干。
恶硫黄、斑蝥、芜荑。其类有四种∶一大形，纯黄色，为蛇医母，亦名蛇舅母，不入药；
次似蛇医，小形长尾，见
人不动，名龙子；次有小形而五色，尾青碧可爱，名断蜴，并不螫
人；一种喜缘篱壁，名 蜓，形小而黑，乃言螫人必死，而未常闻中人。案东方朔云∶若非
守宫，则蜥蜴是，如此 蜓名守宫矣。以朱饲之，满三斤，杀，干末以涂女子身，有交接事
便脱，不尔如赤志，故谓守
宫。今此一名守宫，犹如野葛、鬼臼之义也，殊难分别。
〔谨案〕
此言四种者∶蛇师，生山谷，头大尾短小，青黄或白斑者是； 蜓，似蛇师，不生山谷，
在人家屋壁间，荆楚及江淮人名 蜓，河济之间名守宫，亦名荣螈，又名蝎虎，以其常在屋
壁，故名守宫，亦名壁宫，
未必如术饲朱点妇人也，此皆假释尔。其名龙子及五色者，并名蜥蜴，以五色者为雄而良，
色不备者为雌，劣尔，形皆
细长，尾与身相类，似蛇，着四足，去足便直蛇形也。蛇医则不然。案《尔雅》亦互言之，
并非真说。又云朱饲满三斤，
殊为谬矣。
Salty in flavor, cold in nature, slightly toxic. Primarily treats five types of strangury (difficulty or inability to urinate) and stagnant evil qi, breaks down stone strangury (urinary calculi), directs blood downward, and promotes the free flow of urine through the urinary pathways. Also known as Xiyi (Lizard), Shanlongzi (Mountain Dragon Son), Shougon (Guardian Palace), and Shi Yi (Stone Lizard).
Grows in the valleys of Pingyang and among the rocks of Jing Mountain. Harvested in the fifth lunar month, dried on stones.
Adversely affected by Liu Huang (Realgar), Ban Mao (Mylabris), and Wu Ti (Hovenia dulcis seed). There are four varieties: one is large in size, purely yellow, called Sheyi Mu (Snake Doctor Mother), also named Shejiu Mu (Snake Uncle Mother), not used in medicine; the second resembles the Snake Doctor, small in size with a long tail, remains motionless when seeing people, called Longzi (Dragon Son); the third is small in size with five colors, has a lovely cyan-green tail, called Duanyi (Broken Lizard), neither bites humans; the fourth likes to climb fences and walls, called Ting, small in size and black, it is said that being bitten by it leads to death, yet no one has ever heard of someone being bitten by it. According to Dongfang Shuo: if it is not Shougon, then Xiyi is it; thus, this Ting can be called Shougon. Fed with Zhu Sha (Cinnabar) until it reaches three jin in weight, killed, ground into powder, and applied to a woman's body; if sexual intercourse occurs, the powder will detach, otherwise it remains like Chizhi (a red forehead mark), hence called Shougon. Currently, this name is also Shougon, similar to the meanings of Yege (Aconitum carmichaelii root) and Guijiu (Podophyllum peltatum rhizome), making them difficult to distinguish.
[Respectful Commentary]
The four varieties mentioned here: Sheshi grows in mountain valleys, has a large head and short tail, appearing greenish-yellow or with white spots; Ting resembles Sheshi but does not grow in mountain valleys, instead inhabiting house walls; people in Jingchu and Jianghuai regions call it Ting, while those between the Yellow River and Ji River call it Shougon, also named Rongyuan, or Xiehu (Scorpion Tiger), because it often stays on walls, hence called Shougon or Bigong (Wall Palace); it is unlikely that it involves feeding cinnabar to touch women as described, these are all false interpretations. Those named Longzi and having five colors are all called Xiyi; the five-colored ones are male and superior, while those with incomplete colors are female and inferior; their shapes are slender, tails resemble bodies, looking like snakes, possessing four feet, becoming straight snake-like when legs are removed. Sheyi is different. According to "Erya", they are used interchangeably, which is not truly accurate. Furthermore, claiming that feeding cinnabar until reaching three jin is highly absurd.
