（收录于《神农本草经》下品）
【释名】鬼桃（出自《本经》）、羊肠（同义）、细子（具体含义不详）。
【集解】《名医别录》记载：羊桃生长在山林、河谷及田野之中。二月采收，阴干备用。
陶弘景说：山野中多有生长。它非常像家桃，但又不是山桃。花朵颜色很红。果实细小且味道苦涩，不能食用。《诗经》中说：“低湿之地有苌楚”，指的就是这种植物。现在方药中不再使用。
苏保升说：生长在平原沼泽中，到处都有。茎叶细长而柔弱，不能长成树木。叶子和花都像桃树，果实细小像枣核，现在人叫它细子，它的根像牡丹。郭璞说：羊桃，叶子像桃叶，花是白色的，果实像小麦，形状也类似桃子。陆玑在《毛诗草木鸟兽虫鱼疏》中说：叶子长而狭窄，花呈紫红色。枝条茎干柔弱，超过一尺就会缠绕在草上蔓延。现在人们用它做汲水用的绳索，因为它重且容易下沉，不如杨柳好。靠近根部，用刀削去外皮，放在热灰中脱皮，可以用来包裹笔管。
李时珍说：羊桃，茎粗如手指，像树但柔弱如藤蔓，春天长出嫩条，质地柔软。叶子大如手掌，上面绿色下面白色，有毛，形状像苎麻但更圆润。其枝条浸水后有黏滑的汁液。
【主治】治疗热病，身体突然发红，清除小儿内热，消除风水积聚引起的病症，治疗恶疮（出自《本经》）。去除五脏积水、大腹水肿，通利小便，益气，可用作洗浴汤剂（出自《别录》）。煮成汁液，洗涤风痒及各种疮肿，效果极佳（出自孟诜）。
根：浸泡酒中服用，治疗风热导致的身体消瘦虚弱（出自陈藏器）。
【附方】旧方一个，新方三个。
伤寒变证，四肢烦痛，食欲不振，嗜睡：用羊桃十斤捣烂，浸入三斗热汤中，在正午时分，坐入其中浸泡一顿饭的时间。不超过三次即可痊愈。（出自《千金方》）
伤寒毒邪攻冲，手足肿痛：用羊桃煮汁，加入少量盐豉浸泡患处。（出自《肘后备急方》）
水气鼓胀，大小便涩滞：用羊桃根、桑白皮、木通、大戟（炒制）各半斤（切碎）。用水一斗，煮取五升，熬制成稀糖状。每次空腹用茶送服一匙。待二便利通后，喝粥来补养身体。（出自《圣惠方》）
蜘蛛咬伤中毒：将羊桃叶捣烂敷在患处，立即痊愈。（出自《备急方》）
(Recorded in the Lower Grade of *Shennong Bencao Jing*)
**Names:** Gui Tao (Ghost Peach, from *Benjing*), Yang Chang (Sheep Intestine, same meaning), Xi Zi (Fine Seed, details unclear).
**Collection and Explanation:** *Bielu* states: Yang Tao grows in mountains, forests, river valleys, and fields. It is harvested in the second lunar month and dried in the shade.
Tao Hongjing says: It is abundant in wild mountains and hills. It closely resembles the domestic peach (*Prunus persica*) but is distinct from the mountain peach. Its flowers are very red. The fruit is small, fine, and bitter, making it inedible. The *Classic of Poetry* states: "In the lowlands there is Chang Chu," referring to this plant. It is no longer used in medical prescriptions.
Su Baosheng says: It grows in plains and marshes and is found everywhere. The stems are long and weak, unable to grow into trees. The leaves and flowers resemble those of the peach tree; the fruits are small like jujube pits. People now call it Xi Zi. Its root resembles that of the peony (*Paeonia lactiflora*). Guo Pu said: Yang Tao has leaves resembling peach leaves, white flowers, and fruits like wheat grains, also similar in shape to peaches. Lu Ji in his *Commentary on the Classic of Poetry* stated: The leaves are long and narrow, with purple-red flowers. The branches and stems are weak, extending over a foot and creeping along grass. People now use it for making ropes for drawing water because it is heavy and sinks easily, which is inferior to willow. Near the base, one can cut off the bark with a knife and place it in hot ashes to remove it; it can then be used to wrap pen tubes.
Li Shizhen says: Yang Tao has stems as thick as a finger, resembling a tree but weak and vine-like. In spring, tender shoots grow soft. The leaves are palm-sized, green on top and white underneath, hairy, and shaped like ramie (*Boehmeria nivea*) but rounder. When its stems are soaked in water, they produce a slimy substance.
**Stems and Roots**
**Nature and Flavor:** Bitter, Cold, Toxic.
Chen Cangqi says: Sweet, Non-toxic.
**Indications:** Treats heat conditions, sudden reddening of the body, clears internal heat in children, resolves accumulation due to Wind-Water, and treats malignant sores (*Benjing*). Removes five types of water retention in the five Zang organs, abdominal distension, promotes urination, tonifies Qi, and can be used as a bathing decoction (*Bielu*). Boiled into juice, it washes away wind-induced itching and various swelling sores with extreme efficacy (Meng Shen).
Roots: Soaked in wine and taken orally to treat emaciation and weakness caused by Wind-Heat (Chen Cangqi).
**Attached Prescriptions:** One old prescription, three new ones.
For Typhoid fever transforming into complications, with vexing pain in the four limbs, anorexia, and excessive sleepiness: Take ten jin of Yang Tao, pound it until熟 (cooked/softened), soak it in three dou of hot water. At noon, sit in the solution for the duration of cooking a meal. It will heal within no more than three treatments (*Qianjin Fang*).
For typhoid toxin attacking, causing swelling and pain in hands and feet: Boil Yang Tao to make juice, add a little salt and fermented soybeans, and soak the affected area (*Zhouhou Fang*).
For edema with drum-like abdominal distension and difficulty in urination and defecation: Use half a jin each of Yang Tao roots, Mulberry Root Bark (*Morus alba* root bark), Akebia Stem (*Akebiae Caulis*), and Spurge Root (*Euphorbiae Radix*, stir-fried) [chopped]. Add ten dou of water, boil down to five sheng, and simmer until it resembles thin syrup. Take one spoonful on an empty stomach with tea. Once urination and defecation become smooth, nourish the body with porridge (*Shenghui Fang*).
For spider bite toxicity: Pound fresh Yang Tao leaves and apply them externally to the site; healing occurs immediately (*Beiji Fang*).
