（雷丸出汉中、建平、宜都及房州、金州诸处，生竹林土中，乃竹之余气所结，故一名
竹苓
。上无苗蔓，大小如栗，状似猪苓而圆，皮黑而微赤，肉白甚坚实。）
雷丸是竹之余气，感雷震而生，竹茎叶青翠，具东方生发之义。震为雷，乃阳动于下，
雷丸
气味苦寒，禀冬令寒水之精，得东方震动之气，故杀阴类之三虫，而逐邪毒之气，得寒水之
精，故清胃中热。震为雷，为长男，故利丈夫，不利女子。
（按∶《别录》云∶雷丸久服令人阴痿，当是气味苦寒，久服则精寒故耳。男子多服阳
痿，
则女子久服子宫寒冷，不能受孕，其不利可知。《本经》乃两分之曰∶利丈夫，不利女子，
未审何义。马志云∶疏利男子元气，不疏利女子脏气。隐庵以震为雷，为长男为解，均未得
当，尚当另参。）

（代赭石《本经》名须丸，《别录》名血师，研之作朱色，可以点书，故俗名土朱，又

赭石，铁之精也，其色青赤，气味苦寒，禀水石之精，而得木火之化。主治鬼疰贼风蛊

故治贼风蛊毒也。杀精物恶鬼，所以治鬼疰也。腹中毒，所以治蛊毒也。邪气，所以治贼风
也。赭石，一名血师，能治冲任之血，故治女子赤沃漏下。
【雷丸】
气味苦寒，有小毒。主要功效是杀灭三虫（肠道寄生虫），驱除体内的毒瓦斯，清除胃中的热邪。对男子有利，但对女子不利。
（雷丸产于汉中、建平、宜都以及房州、金州等地，生长在竹林下的土壤中，是竹子剩余之气凝结而成，所以又名竹苓。上面没有苗蔓，大小像栗子，形状像猪苓但更圆，外皮黑色略带红色，肉质白色且非常坚实。）
雷丸是竹子的余气，感应雷电震动而生。竹子的茎叶青翠，具有东方生发之意。震卦代表雷，是阳气在下方发动。雷丸的气味苦寒，禀受了冬季寒水的精气，又获得了东方震动的气机，因此能杀灭属阴类的三虫，并驱逐邪毒之气；因为禀受了寒水的精气，所以能清解胃中的热邪。震卦代表雷，也代表长男，所以对男子有利，对女子不利。
（按语：《名医别录》说：长期服用雷丸会导致阳痿，这应该是由于气味苦寒，长期服用导致精气寒冷所致。男子多服会导致阳痿，那么女子长期服用则会导致子宫寒冷，无法受孕，其不利于女子的情况就显而易见了。《神农本草经》将其分为两点说：“利丈夫，不利女子”，不知是何含义。马志说：疏利男子的元气，不疏利女子的脏气。隐庵以震为雷、为长男来解释，都不得要领，还需要另行参考。）
【代赭石】
气味苦寒，无毒。主治鬼疰（一种慢性消耗性传染病）、贼风（不正之风）、蛊毒，能杀死精怪恶鬼，治疗腹中的中毒邪气，以及女子赤沃漏下（妇女白带过多或崩漏）。
（代赭石在《神农本草经》中名为须丸，《名医别录》中名为血师，研磨后呈朱红色，可以用来写字，所以俗称土朱，又名铁朱。管子说：山上有赭石，山下就有铁。《北山经》说：少阳之山中盛产优质的赭石。《西山经》说：石脆山的灌水发源于此，水中含有流赭，说的都是这种石头。《名医别录》说：代赭石产于齐国山谷，颜色赤红带青，像鸡冠一样有光泽，梁爪甲不渝者良（此处原文可能有误，通常指质地细腻坚硬，指甲划不留痕者为佳）。现在代州、河东、江东各地的山中都有出产，以西北方向出产的质量最好。）
赭石是铁的精华，颜色青赤，气味苦寒，禀受了水石的精气，同时获得了木火的化育。主治鬼疰、贼风、蛊毒，是因为其色赤属火，获得了少阳火热之气，所以鬼疰自然消除；石头性质沉重，青色属木，木获得了厥阴风木之气，所以能治疗贼风和蛊毒。杀死精物恶鬼，是用来治疗鬼疰的；治疗腹中毒，是用来治疗蛊毒的；治疗邪气，是用来治疗贼风的。赭石，又名血师，能够调理冲脉和任脉的血分，所以能治疗女子的赤沃漏下。
[Leiwan / Polyporus]
Taste and nature: Bitter, cold; slightly toxic.
Main actions: Kills the "three worms" (intestinal parasites), expels toxic vapors, clears heat in the stomach. Beneficial for men, but not beneficial for women.
(Note: Leiwan is produced in Hanzhong, Jianping, Yidu, Fangzhou, Jinzhou, and other places. It grows in the soil under bamboo forests and is formed from the residual qi of bamboo, hence also known as Zhuling (Bamboo Poria). It has no stems or vines above ground, is as large as a chestnut, resembles Zhu Ling (Alisma) but is rounder, has black skin with a slight reddish tint, and white flesh that is very solid.)
Leiwan is the residual qi of bamboo, generated by sensing thunder and lightning. The stems and leaves of bamboo are green and lush, embodying the generative meaning of the East. Zhen (Thunder) represents thunder, which is yang moving from below. Leiwan possesses bitter and cold properties, inheriting the essence of winter's cold water, and acquiring the qi of eastern vibration. Therefore, it kills the yin-type "three worms" and expels pathogenic toxic qi. Having inherited the essence of cold water, it clears heat in the stomach. Zhen represents thunder and also the eldest son; thus, it is beneficial for men but not for women.
(Commentary: *Bencao Jing Jizhu* states that long-term consumption of Leiwan causes impotence. This is likely because its bitter and cold nature, when consumed over a long period, leads to coldness in the essence. Excessive consumption by men causes impotence; therefore, long-term consumption by women would cause coldness in the uterus, leading to infertility, making its detrimental effect on women evident. *Shennong Bencao Jing* divides this into two points: "Beneficial for men, not beneficial for women," the rationale of which is unclear. Ma Zhi stated that it disperses the primordial qi of men but does not disperse the viscera qi of women. Yinan explained it using the concept of Zhen as thunder and eldest son, but these interpretations are inadequate and require further reference.)
[Dai Zhe Shi / Hematite]
Taste and nature: Bitter, cold; non-toxic.
Main actions: Treats Guizhu (a chronic wasting disease attributed to spirits), Zeifeng (evil winds), Guduh (gu poison); kills evil spirits and demons; treats toxic pathogenic qi in the abdomen; and treats Chiwu Louxia (leukorrhea or metrorrhagia in women).
(Note: Dai Zhe Shi was named Xuwan in *Shennong Bencao Jing* and Xueshi (Blood Master) in *Bencao Jing Jizhu*. When ground, it produces a vermilion color and can be used for writing, hence commonly known as Tuzhu (Earth Vermilion) or Tiezhu (Iron Vermilion). *Guanzi* says: Where there is hematite on the mountain, there is iron beneath. *Beishanjing* says: The mountains of Shaoyang produce fine hematite. *Xishanjing* says: The Guan River originates from Mount Cuishi, containing flowing hematite; all refer to this stone. *Bencao Jing Jizhu* states: Dai Zhe Shi grows in the valleys of Qi State, appearing red and cyan, glossy like a rooster's comb. Those that do not wear down when scratched by fingernails are considered good. Currently, it is found in mountains throughout Daizhou, Hedong, and Jiangdong, with those from the northwest being of superior quality.)
Zhe Shi (Hematite) is the essence of iron. Its color is cyan-red, and its taste and nature are bitter and cold. It inherits the essence of water and stone while undergoing the transformation of wood and fire. It treats Guizhu, Zeifeng, and Guduh because its red color belongs to Fire, acquiring the hot qi of Shaoyang, thereby causing Guizhu to dissipate. Stone nature is heavy and sedating; its cyan color belongs to Wood, acquiring the wind-wood qi of Jueyin, thus treating Zeifeng and Guduh. Killing evil spirits and demons serves to treat Guizhu. Treating abdominal toxicity serves to treat Guduh. Treating pathogenic qi serves to treat Zeifeng. Dai Zhe Shi, also known as Xueshi (Blood Master), can regulate the blood of the Chong and Ren meridians, thus treating Chiwu Louxia in women.
