味苦，性温、微寒，有大毒。主治心痛，寒热结气，积聚伏梁（腹内结块），损伤筋脉导致的痿软拘挛或弛缓，通利水道，去除阴部潮湿，治疗风眩（因风邪引起的眩晕）。产于汉中山谷及冤句。二月、八月采集，阴干。（蜀漆为其辅药，畏莽草。）
陶隐居说：附近道路也有出产。形状像半夏，但都比较大。四周有子芽像老虎的脚掌。现在使用多将其破开，分为三、四片而已。方剂中也不常正用此药。《唐本草》注解说：这种药是由跋宿根长成的。它的苗一茎，茎头一叶，枝丫分叉于茎旁。根大的如拳头，小的如鸡蛋，整体都像扁柿子，四周有圆形的牙状突起，看起来像虎掌，所以有此名。其由跋是新根，比半夏大两、三倍，只是四周没有子牙罢了。陶隐居说虎掌像半夏，就是指由跋，把由跋当作半夏，解释由跋的苗，完全是在说鸢尾。南方人至今仍然用由跋当作半夏。臣禹锡等人谨按《蜀本图经》说：它的茎端有八、九片叶子，花生在茎之间。根周围有芽，然而像兽掌一样。吴氏说：虎掌，神农、雷公认为味苦，无毒。歧伯、桐君认为味辛，有毒。立秋、九月采集。《药性论》说：虎掌，使药，味甘。不入汤剂服用，治疗风眩目转，主治疝瘕肠痛，主治伤寒时疾，强阴。
《图经》说：虎掌，产于汉中山谷及冤句，现在河北州郡也有。初生的根像豆子大，逐渐长大像半夏而扁平，多年生的，其根圆且一寸大，大的如鸡蛋。周围生圆形芽二、三枚，或五、六枚。三月、四月生苗，高一尺多。独茎上有叶如爪，五、六出分布，尖而圆。一窝生七、八茎，时常出一茎作穗，直上如鼠尾。中间生一叶如匙，包裹茎作房，旁开一口，上下尖。中有花，微青褐色。结实如麻子大，熟即白色，自然脱落铺在地上，一子生一窝。九月苗残取根，将水放入容器中，浸泡五、七日，水冷后更换。每天换三、四遍，洗去涎液，晒干使用。或者再火炮。现在冀州人在菜园中种植它，也呼为天南星。江州有一种草，叶大如掌，面青背紫，四周有芽像虎掌，生三、五叶为一株，冬季常青。治心痛寒热积气，不结花实，与此同名，故附见之。
Arum Tenuifolium (Huzhang)
Bitter in taste, warm and slightly cold in nature, possessing great toxicity. It primarily treats heart pain, stagnation of qi with cold and heat, accumulations and fuliang masses (subcutaneous lumps in the abdomen), tendons damaged leading to flaccidity, spasms, or laxity, promotes urination, eliminates dampness in the genital area, and treats wind-induced vertigo. It grows in the valleys of Hanzhong and Yuanju. Harvested in February and August, dried in the shade. (Shuqi [Stem of *Tripterygium wilfordii*] acts as its assistant; it is incompatible with Mangcao [Root bark of *Daphne genkwa*].)
Tao Hongjing stated: It is also found near the roads. Its shape resembles Banxia (*Pinelliae Rhizoma*), but is generally larger. It has small tubers on all sides resembling a tiger's paw. Currently, it is often broken into three or four pieces for use. It is not commonly used as a principal herb in prescriptions. The annotation in *Tang Bencao* states: This drug grows from the perennial root of Youba (*Iris tectorum*). Its seedling has one stem with one leaf at the tip, branching off the stem. The roots are large like a fist or small like a chicken egg, generally resembling flat persimmons, with round tooth-like projections on all sides, looking like a tiger's paw, hence the name. The "Youba" refers to the new root, which is two to three times larger than Banxia, but lacks the peripheral tooth-like projections. Tao claimed that Huzhang resembles Banxia, referring to Youba, mistaking Youba for Banxia and describing the seedling of Iris. Southerners still use Youba (*Iris tectorum*) as a substitute for Banxia today. Ministers Yuxi and others carefully noted according to *Shuben Tujing*: There are eight or nine leaves at the tip of the stem, with flowers growing between the stems. Buds surround the root, resembling an animal's paw. Wu stated: For Huzhang, Shennong and Leigong considered it bitter and non-toxic. Qibo and Tongjun considered it acrid and toxic. Harvested at Lqiu (Start of Autumn) and in September. *Yaoxing Lun* states: Huzhang, when used as an assistant herb, is sweet in taste. It should not be taken in decoctions; it treats wind-induced vertigo and spinning eyes, primarily manages hernia and abdominal masses with intestinal pain, treats shanghan and seasonal epidemics, and strengthens the yin.
*Tujing* states: Huzhang grows in the valleys of Hanzhong and Yuanju, and is now also found in prefectures and commanderies of Hebei. Newly grown roots are bean-sized, gradually enlarging to resemble flattened Banxia. Perennial roots become round, about one cun in diameter, with large ones reaching the size of a chicken egg. Two to three, or five to six, round buds grow around the circumference. Seedlings emerge in March and April, growing over one chi high. A single stem bears leaves like claws, distributed in fives or sixes, pointed and round. One cluster produces seven or eight stems, occasionally sending up one stem forming a spike, straight upward like a rat's tail. A spoon-shaped leaf grows in the middle, enclosing the stem like a chamber, opening to one side, pointed at both ends. Flowers inside are slightly greenish-brown. Fruits are sesame-seed sized, turning white when ripe, falling naturally to the ground; each seed generates a new cluster. In September, after the seedlings wither, roots are harvested. They are soaked in water in a vessel for five to seven days, changing the water when it cools. Changed three or four times daily, washed to remove saliva-like mucus, then sun-dried. Alternatively, stir-fried with fire. People in Jizhou now cultivate it in vegetable gardens, also calling it Tiannanxing (*Arisaema erubescens*). In Jiangzhou, there is a grass with leaves palm-sized, green on top and purple underneath, with peripheral buds resembling a tiger's paw. Three to five leaves form one plant, remaining evergreen in winter. It treats heart pain, cold-heat accumulated qi, does not produce flowers or fruits, shares the same name, thus included here for reference.
