篮，言其小而篮不能盛，漏出篮下也。专治冷漏恶疮。
一名毒公
辛热，大毒。即乌头之野生者。或生用，或炮用，各随本方。有两岐相合如乌之喙者，
名乌喙。

侧子
味辛，性热，有大毒。
发明：侧子是散生在乌头、附子植株旁边的块根，其形态位置不固定，药气轻清上扬，因此适宜发散四肢经络的风邪，通达皮毛，是治疗风病的药物。唐代元希声治疗瘫痪症，使用了侧子汤，记载于《外台秘要》中。另外，附子初生时细小未长成者，称为“漏篮”，意思是它太小了，篮子都盛不住，从篮底漏出来。专门用于治疗冷性漏疮和恶疮。
草乌头
又名毒公。
味辛，性热，有大毒。即野生状态的乌头。可以生用，也可以炮制后使用，具体根据原方要求而定。其中有两个分枝合生在一起，形状像乌鸦嘴的，称为“乌喙”。
《神农本草经》主治中风引起的恶风、身体战栗出汗，去除寒湿痹痛、咳嗽气逆上冲，破除积聚导致的寒热症状。其汁液煎煮浓缩后，称为“射罔”，可用于毒杀禽兽。
发明：草乌头和射罔是毒性极大的药物，不像川乌头和附子那样相对温和。如果不是顽固急重的风疾，不可轻易使用。此药只能搜剔风邪、胜除湿气、开通顽痰、治疗顽固疮疡，属于以毒攻毒的方法。《神农本草经》说它能治恶风、战栗汗出，但只能祛除恶风，而不能回阳散寒，由此可知。过去有人患风癣服用草乌头和木鳖子的药量过多，刚进入腹部就导致麻痹死亡，无法救治。乌头、附子这五种药物的主治功效是有区别的：附子大补元阳，虽然主要作用于下焦，但能通达周身内外；天雄峻补元气不亚于附子，但没有顷刻间回阳救逆的功效；川乌专门搜剔风湿引起的痛痹，却缺少温通经脉的力量；侧子善于通行四肢末端，不入脏腑；草乌药性悍烈，仅适合外用。这是乌头类药材同类而性质不同的地方。至于乌喙，禀受之气不纯正，服用时应远离它。
射罔
味苦，性温，有大毒。
如果误中射罔之毒，可以用甘草、蓝汁（板蓝根或蓼蓝汁）、小豆叶、浮萍、冷水、荠菜中的任意一种单味药来解毒。
发明：乌喙和射罔是毒性极强的药物。虽然有治疗尸疰（慢性消耗性疾病）、坚硬疮毒肿及蛇咬伤的作用，但必须先取药涂抹在疮口四周，逐渐向中心靠近，让药力慢慢渗透至病骨。只有当疮口有热脓和黄水水肿时，才可以涂抹。如果没有脓水，或者是新鲜出血伤口、新近破损的皮肤，就绝对不可涂抹，否则会立即致人死亡。
Cizi (Lateral Root of Aconitum)
Pungent, hot, highly toxic.
Invention: Cizi is the lateral root growing beside the main roots of Wutou (Aconiti Radix) and Fuzi (Aconiti Lateralis Radix Praeparata). Its position is irregular, and its qi is light and ascending. Therefore, it is suitable for dispersing wind in the four limbs and reaching the skin and hair, serving as a medicine for treating wind disorders. In the Tang Dynasty, Yuan Xisheng treated paralysis with Cizi Tang, recorded in *Waitai Miyao* (Essential Prescriptions Worth a Thousand Gold for Emergencies). Additionally, young, small, and undeveloped Fuzi are called "Louban" (Leaking Basket), meaning they are so small that they cannot be held in a basket and leak out from underneath. It is specifically used to treat cold-type draining ulcers and malignant sores.
Caowutou (Wild Aconite)
Also known as Dougong.
Pungent, hot, highly toxic. It refers to wild-growing Wutou (Aconiti Radix). It may be used raw or processed, depending on the specific prescription. Those with two branches fused together, resembling a crow's beak, are named Wu Hui (Crow's Beak).
*Shennong Bencao Jing* (Divine Farmer's Materia Medica) states it treats wind-stroke with aversion to wind, shivering sweating, removes cold-damp bi-syndrome, cough with rebellious qi, and breaks up accumulations causing cold-heat symptoms. Its juice, when boiled down, is called She Wang (She Wang Poison), which can kill birds and beasts.
Invention: Caowutou and She Wang are substances of extreme toxicity, unlike Chuan Wutou (Sichuan Aconite) and Fuzi. They should not be lightly administered unless for stubborn and acute wind diseases. This drug can only search out wind, overcome dampness, open up stubborn phlegm, and treat stubborn sores, acting by using toxicity to combat toxicity. Although *Shennong Bencao Jing* mentions treating aversion to wind and shivering sweat, it indicates that it can only dispel aversion to wind but cannot restore yang and dissipate cold. In the past, patients suffering from wind-xanthoma took excessive amounts of Caowutou and Mubiezi (Strychnos Nux-vomica Seed); upon entering the stomach, they became paralyzed and died without rescue. The therapeutic indications for the five types of Wutou and Fuzi are distinct: Fuzi greatly strengthens primal yang; although it primarily acts on the lower jiao, it reaches everywhere inside and outside the body. Tianxiong (Aconiti Radix) provides severe tonification comparable to Fuzi but lacks the instantaneous effect of restoring yang. Chuanwu (Chuan Wutou) specializes in searching out wind-damp painful bi-syndrome but lacks the power to warm meridians. Cizi excels at circulating in the four extremities and does not enter the zang-fu organs. Caowutou is fierce and potent, suitable only for external treatment. These are examples of similar origins but different natures within the Wutou family. As for Wu Hui, its acquired qi is impure; one should avoid consuming it.
She Wang (Poisonous Juice of Aconite)
Bitter, warm, highly toxic.
If poisoned by She Wang, any single herb among Gancao (Licorice Root), Lan Zhi (Isatis Leaf Juice), Xiaodou Ye (Adzuki Bean Leaves), Fuping (Duckweed), Leng Shui (Cold Water), or Jicai (Shepherd's Purse) can be used alone to counteract the poison.
Invention: Wu Hui and She Wang are drugs of extreme toxicity. Although they have uses for treating Shizhu (chronic wasting disease), hard sores, swelling, and snake bites, one must first apply the medicine to the periphery of the wound, gradually moving closer to the center, allowing the medicinal force to slowly penetrate to the bone. It may only be applied if there is hot pus and yellow edematous fluid in the sore. If there is no pus/fluid, or if there is fresh bleeding or new traumatic wounds, it must absolutely not be applied, as it will immediately cause death.
