味辛、温、微温，有毒。主杀蛊毒鬼疰精物，辟恶气不祥，逐邪，解百毒。疗咳嗽喉结，
风邪烦惑，失魄妄见，去
目中肤翳，杀大毒，不入汤。一名爵犀，一名马目毒公，一名九臼，

一名九臼。生山谷，八月采，
阴干。又似钩吻。今马目毒公如黄精，根臼处似马眼而柔润；鬼臼似射干、术辈，有两种∶
出钱塘、近道者，味甘，上
有丛毛，最胜；出会稽、吴兴者，乃大，味苦，无丛毛，不如，略乃相似而乖异毒公。今方

【鬼臼】
味道辛，性温及微温，有毒。主要功效是杀灭蛊毒、鬼疰（一种由邪气引起的慢性消耗性疾病）及精怪之物，驱除恶气和不祥之气，驱逐邪气，解除各种毒素。治疗咳嗽、喉部结块，风邪引起的烦闷困惑，神志失常、幻觉妄见，去除眼中翳膜，杀死大毒，但不宜入汤剂服用。又名爵犀，又名马目毒公，又名九臼，又名天臼，又名解毒。产于九真山谷及宛朐。二月和八月采集根部。畏忌垣衣（墙上的苔藓或地衣）。
【毒公】
鬼臼形状像射干，白色且味甘，性温，有毒。治疗风邪、鬼疰、蛊毒。九臼相连、有毛的为优良品，又名九臼。产于山谷，八月采集，阴干。又类似钩吻。现在的马目毒公形状像黄精，根部和臼状处像马眼一样柔润；鬼臼形状像射干、白术之类，有两种：出产于钱塘、靠近道路的那些，味甘，上面有丛生的毛，品质最好；出产于会稽、吴兴的那些，体积较大，味苦，没有丛生的毛，品质较差，虽然略微相似但毒性不同。现在方家多用鬼臼，少用毒公。
〔谨案〕这种药生长在深山岩石的背阴处。叶子像蓖麻、重楼之类。生出一根茎，茎端长一片叶，也有分两歧的。每年长一根茎，茎枯萎后形成一个臼。假如生长了二十年，就有二十个臼，哪里只有九个臼呢？根的肉质、外皮和须根都像射干。现在民间使用的都是射干，以及江南另外送来的某种东西，都不是真的。现在荆州当阳县、硖州远安县、襄州荆山县的山中都有这种药，极难得到。
【芦根】
味道甘，性寒。主要功效是治疗消渴（糖尿病症状），清除客热（外感余热），止住小便频数。应当挖掘甘甜辛辣味的芦根，那些露出地面的以及漂浮在水中的，都不堪使用。
〔谨案〕这种草，其根治疗呕吐逆气、不能进食，胃中热，对于伤寒患者尤为适宜。它的花名叫蓬葈，用水煮汁服用，主治霍乱，效果很好，使用有验证。

[Dougong]
Guibai resembles Shenggan (Belamcanda chinensis), is white, has a sweet taste, is warm, and toxic. It treats wind-pathogens, guizhu, and gu poison. Those with nine connected corms and having hairs are of good quality, also known as Jiujiu. Grows in valleys, harvested in August, dried in shade. It also resembles Gouwen (Gelsemium elegans).
Current Maimu Dougong resembles Huangjing (Polygonatum sibiricum); its root and corm resemble a horse's eye and are soft and moist. Guibai resembles Shenggan and Baizhu (Atractylodes macrocephala). There are two types:
1. Those from Qiantang and near roads have a sweet taste, possess clustered hairs on top, and are of the highest quality.
2. Those from Kuaiji and Wuxing are larger, bitter in taste, lack clustered hairs, and are inferior. Although slightly similar, their toxicity differs.
Currently, practitioners mostly use Guibai and rarely use Dougong.
[Commentary]
This medicine grows in the shade of deep mountain rocks. The leaves resemble those of Ricinus communis (Castor bean) and Chonglou (Paris polyphylla). It produces a single stem, with one leaf at the tip, sometimes bifurcated. Each year, one stem grows; when the stem withers, it forms one corm. If it grows for twenty years, there will be twenty corms, not merely nine. The root flesh, skin, and fibrous roots resemble Shenggan. Currently, what is commonly used is Shenggan, or another item sent from Jiangnan, neither of which is authentic. Currently, this herb exists in the mountains of Dangyang County in Jingzhou, Yuan'an County in Xia Prefecture, and Jingshan County in Xiangzhou, but it is extremely difficult to obtain.
[Lugen]
Taste: Sweet. Nature: Cold.
Main actions: Primarily treats Xiaoke (消渴, diabetes mellitus/wasting-thirst syndrome), clears residual heat (客热), and stops frequent urination (小便利).
Selection criteria: Dig up those with sweet and pungent tastes. Those exposed to air or floating on water are unsuitable for use.
[Commentary]
The root of this herb treats vomiting and inability to eat, heat in the stomach, and is particularly beneficial for patients with Shanghan (Cold Damage). Its flower, named Pengxi (蓬葈), when boiled in water and the juice taken, primarily treats Huoluan (霍乱, cholera-like syndrome) with great efficacy, as verified by use.
