又名双珠草。生长在人家倒塌的墙壁和古老的石阶之间，叶片形状像小将军草但更小，谷雨节气后开出细碎的小花，枝桠间结出细小的果实，形状像肾脏。
又类似花椒的形状，青色且带有微毛，在立夏时节采集。《百草镜》记载：它蔓延生长，喜欢长在土墙头上，二、三、四月可以采集，五月就没有了。二月长出苗，是种小草。三、四月间在节和枝桠中结子，形状像外肾（睾丸），里面有两颗细小的核，性温，治疗疝气，药力下行至下部，以发大汗为妙。治疗腰痛。
疝气：《澹寮方》用新鲜的狗卵子草二两，捣烂取汁，用白酒调和服用，在饥饿时服药直至喝醉，盖上被子保暖睡觉，等待发出大汗，病自然痊愈。这种草性温，能通达下部，如果没有鲜草，必须在三、四月采摘晒干保存。如果使用干草，只适宜用一两，用白酒煎煮。加入紫背天葵五钱，同煎效果更好。庚戌年，我在临安馆舍居住，暑热过后荒废的园圃里多生此草，惊蛰后长苗，像小将军草但叶子较小，颜色也是淡绿色，春分后就开花，细碎，藕合色，节和枝桠处都有花，结出的果实像狗卵，饱满可观。这种草蔓生在地面上，千百穗并生于一根茎上，立夏后大多枯萎。我的室友许家的儿子年幼时患疝气，发作时就会昏厥，用这种草煎酒服用，后来永远不再发作。
又名洞里神仙，又名野延胡。江南人叫它飞来牡丹，到处都有，叶子像牡丹但较小，根长二三寸，春天开紫色小花成穗状，像柳穿鱼，果实结在枝节间，初生青色老熟变黄，落地后又生出小枝，果实像豆子大，其根下有结节状的颗粒，年代久远的如手指大，小的如豆子大。一种黄花的是蒿属植物，根上没有果实，采集时不可误用。
治疗跌打损伤引起的风气，消除痈肿、便毒、瘰疬、天蛇毒、鸦翅毒，捣烂外敷治疗火丹、痔肿、风痹、闪挫腰痛。
肿毒初起：《百草镜》取一粒金丹根上的果实一两，捣烂取汁，用陈年黄酒调和服用，同时治疗瘰疬初起。
Also known as Shuangzhu Cao (Double Pearl Grass). It grows among the ruined walls and ancient stone steps of households. Its leaves resemble those of Xiaojiangjun Cao (Little General Grass) but are smaller. After the Guyu solar term, it blooms with tiny, fragmented flowers, and small seeds resembling kidneys form between the branches.
It also resembles the shape of Sichuan pepper, is greenish in color with slight hairs, and is harvested at the beginning of Summer (Lixia). *Baicao Jing* records: It spreads and grows, preferring to grow on top of earthen walls; it can be collected in the second, third, and fourth lunar months, but is absent in the fifth month. Sprouts appear in the second lunar month; it is a small herb. In the third and fourth lunar months, seeds form in the nodes and branch axils, shaped like external genitalia (testes), containing two fine kernels inside. It has a warm nature, treats hernia, directs action to the lower body, and inducing profuse sweating is considered optimal. It treats lower back pain.
Hernia: The *Danliao Fang* prescription uses two liang of fresh Gouluanzi Cao (Dog Egg Grass), crushed to extract juice, mixed with white wine for oral administration. The patient should take the medicine until drunk while hungry, cover themselves with blankets to keep warm, sleep, and wait for profuse sweating to occur, after which the disease will heal spontaneously. This herb has a warm nature and can reach the lower body. If fresh herbs are unavailable, they must be harvested in the third or fourth lunar months, dried, and stored. If using dried herbs, only one liang is suitable, decocted in white wine. Adding five qian of Zibeitiankui (Ophiopogon japonicus var. planiscapus 'Nigrescens'), decocted together, yields even better results. In the Gengxu year, I was staying in Lin'an. After the heat, this herb grew abundantly in abandoned gardens. Sprouts emerged after the Awakening of Insects (Jingzhe), resembling Little General Grass but with smaller leaves and a lighter green color. Flowers bloomed after the Spring Equinox, tiny and fragmented, in lotus-root-pink color, appearing at nodes and branch axils. The seeds resembled dog eggs, plump and visually appealing. The herb creeps on the ground, with thousands of spikes growing from a single stem, mostly withering after Lixia. My roommate's son, Mr. Xu, suffered from hernia in his childhood; upon attack, he would faint. He took this herb decocted in wine, and subsequently never suffered another attack.
Also known as Dongli Shenxian (Immortal in the Cave), or Ye Yanyu (Wild Corydalis). People in Jiangnan call it Feilai Mudan (Flying Peony); it is found everywhere. The leaves resemble peony leaves but are smaller. The roots are two to three cun long. In spring, it blooms with small purple flowers in spikes, resembling Willow-Piercing-Fish. Seeds form between the branch nodes, turning from green when young to yellow when old. When falling to the ground, they sprout new small branches. The seeds are bean-sized. At the base of the root, there are nodular granules; in older plants, these are finger-sized, while in younger ones, they are bean-sized. A variety with yellow flowers belongs to the Artemisia genus and lacks seeds on the root; care must be taken not to mistake it during collection.
It treats wind-dampness caused by falls and bruises, dissipates carbuncles, sores, anal abscesses, scrofula, Tianshe Du (Snake Poison), Yachi Du (Crow Wing Poison). Crushed and applied externally, it treats Huodan (Erysipelas), hemorrhoid swelling, wind-bi (wind-rheumatism), and sprain-induced lower back pain.
Initial stage of toxic swelling: *Baicao Jing* prescribes taking one liang of the seeds from the root of Yili Jindan (One Pill Golden Elixir), crushing them to extract juice, and mixing with aged wine for oral administration. This also treats the initial stage of scrofula.
