生长在阴山脚下，立夏时节发出嫩苗，叶子贴着地面生长，形状像兔子耳朵，叶片厚实，边缘有黄色的软刺，茎的背面也长满黄毛。到了寒露时节，从中心抽出花茎，高约五寸左右，上面有倒向下的软刺，这就是它的花。每一枝只开一朵花，所以叫“一枝箭”。入药使用时要用棉布包裹后煎煮，恐怕那些细毛会刺激肺部，导致人咳嗽。
《百草镜》记载：兔耳一枝箭的叶子像橄榄形，边缘有针刺，只有七八片叶子，贴着地面生长，八月抽茎，高度接近一尺，花像穗状且有带刺的苞片，茎和叶都有毛，七月采收。还有小鹿衔、银茶匙、忍冬草、月下红等别名。汪连仕说：兔耳箭刚长出的嫩苗，名叫金茶匙。它能进入血分，止住吐血，治疗肺痈。王安采的药方中说：叶子底部发红的，名叫金茶匙。
药性寒，味道苦，能行血凉血，归肺经，清泻肺火。治疗吐血、劳伤，调和血液效果最好。是治疗虚弱体质的要药。可用于治疗肺痈、肺痿、黄疸、心痛、跌打损伤、风气伤力、咳嗽咯血、肿毒、肠痈、缩脚痈等症。
治肠痈、肺痈、缩脚痈：《慈航活人书》记载：用白石楠叶嫩芽十二个，兔耳草二两，用好酒煎服，肺痈服两剂，肠痈、缩脚痈服一剂，即可痊愈。
治骨蒸劳怯（阴虚发热、身体消瘦）：吴普仁方记载：用兔耳一枝箭蒸鸡食用。
这种药生长在深山中，四五月间当地百姓采集得到，拿到市场上售卖。植株长二三寸，一根茎两个分枝，一个分枝一片叶，叶子像兔子耳朵，又像箭头，分枝细长尖锐，像新发出的竹笋，因此得名。
《百草镜》记载：独叶一枝枪生长在山原上，清明时节发苗，谷雨过后枯死，长二三寸，一叶一花，叶子像橄榄，花像锥钻。
味道甘甜淡平，功效与一枝箭相同。朱斋在《任城日记》中记载：各种毒虫咬伤，用独叶一枝枪草生嚼或捣碎外擦，即可痊愈。
Duye Yizhiqiang (Single-Leaf One-Stem Spear), also known as Jinbian Tu'er (Golden-edged Rabbit Ear) and Tu'er Suan (Rabbit Ear Sour).
It grows at the foot of Yin Mountain. Sprouts emerge during Lixia (Start of Summer). The leaves grow close to the ground, resembling rabbit ears; the foliage is thick, with yellow soft spines on the margins. The back of the stem is covered in yellow hairs. During Hanlu (Cold Dew), a central flower stalk emerges, approximately five cun high, bearing soft, downward-pointing spines, which constitute the flower. Each stalk bears only one flower, hence the name "Yizhi Jian" (One-Stem Arrow). For medicinal use, it should be wrapped in cotton before decoction to prevent the fine hairs from irritating the lungs and causing coughing.
*Bai Cao Jing* (Mirror of All Herbs) records: The leaves of Tu'er Yizhi Jian resemble olives, with spiny margins. There are only seven or eight leaves growing贴地 (close to the ground). The stem emerges in August, reaching nearly one chi in height. The flowers are spike-like with bristly bracts; stems and leaves are hairy. It is harvested in July. Other names include Xiaolu Xian (Little Deer Carrying), Yin Chashi (Silver Tea Spoon), Rendong Cao (Honeysuckle Herb), and Yuexia Hong (Red Under the Moon). Wang Lianshi stated: The initial sprouts of Tu'er Jian are called Jin Chashi (Golden Tea Spoon). It enters the blood level, stops hematemesis, and treats lung abscess. Wang Ancai's prescription notes: Those with red undersides of leaves are named Jin Chashi.
The nature is cold, and the taste is bitter. It promotes blood circulation and cools the blood, enters the Lung meridian, and clears Lung fire. It treats hematemesis and consumptive injury, being most effective in regulating blood. It is an essential herb for treating deficiency and weakness. It is indicated for lung abscess, lung萎 (lung flaccidity), jaundice, heart pain, traumatic injuries, wind-damage strain, cough with hemoptysis, swelling and toxins, intestinal abscess, and leg-curling abscess.
For treating intestinal abscess, lung abscess, and leg-curling abscess: *Cihang Huoren Shu* (Compassionate Book Saving Lives) states: Use twelve tender buds of Baishi Nan leaves and two liang of Tu'er Cao, decocted in good wine. Two doses cure lung abscess; one dose cures intestinal and leg-curling abscesses.
For treating bone-steaming consumption and debility: Wu Puren's formula states: Steam chicken with Duye Yizhi Jian and consume.
It grows in deep mountains. Local people harvest it between April and May and sell it in markets. The plant is two to three cun long, with one stem and two branches; each branch bears one leaf. The leaf resembles a rabbit ear or an arrowhead. The branch is slender and sharp, like a newly sprouted bamboo shoot, hence the name.
*Bai Cao Jing* records: Duye Yizhiqiang grows on mountain plains. Sprouts emerge during Qingming and wither after Guyu. It is two to three cun long, with one leaf and one flower per stalk. The leaf resembles an olive, and the flower resembles a cone drill.
The taste is sweet and bland. Its functions are identical to those of Yizhi Jian. Zhu Zhai, in *Rencheng Riji*, recorded: For bites from various venomous insects, apply fresh Duye Yizhiqiang grass externally by chewing or crushing it; healing occurs immediately.
