（《本经》中品）
【释名】土瓜（《本经》）、钩KT （郭璞）、老鸦瓜（《图经》）、马 瓜（ ，音雹）、
赤雹子（《衍义》）、
颂曰∶《月令》∶四月王瓜生。即此也。均、房间人呼为老鸦瓜，亦曰菟瓜。按《尔雅》
云∶ ，菟瓜。郭璞注云∶似土瓜。而土瓜自谓之KT 姑，又名钩KT ，则菟瓜别是一物
也。
又曰∶芴，菲。亦谓之土瓜。别是一物，非此土瓜也。异类同名甚多，不可不辨。
时珍曰∶土瓜，其根作土气，其实似瓜也。或云根味如瓜，故名土瓜。王字不知何义？
瓜似雹子，熟则色赤，鸦喜食之，故俗名赤雹、老鸦瓜。一叶之下一须，故俚人呼为公公须。
与地黄苗名婆婆奶，可为属对。
【集解】《别录》曰∶生鲁地平泽田野，及人家垣墙间。三月采根，阴干。
弘景曰∶今土瓜生篱院间。子熟时赤如弹丸。其根不入大方，正单行小小尔。郑玄注《
月令》∶四月王瓜生，以为菝 ，殊谬矣。
恭曰∶四月生苗延蔓，叶似栝蒌叶，圆无叉缺，有毛刺。五月开黄花。花下结子如弹丸，
生青熟赤。根似葛，细而多糁，谓之土瓜根。北间者，其实累累相连，大如枣，皮黄肉白。
苗子相似，根状不同。若疗黄胆破血，南者大胜也。
宗 曰∶王瓜，其壳径寸，长二寸许，上微圆，下尖长，七、八月熟，红赤色。壳中子
如螳螂头者，今人又谓之赤雹子。其根即土瓜根也。于细根上又生淡黄根，三、五相连，如
大指许。根与子两用。
时珍曰∶王瓜三月生苗，其蔓多须，嫩时可茹。其叶圆如马蹄而有尖，面青背淡，涩而
不光。六、七月开，五出小黄花成簇。结子累累，熟时有红、黄二色，皮亦粗涩。
但如栝蒌根之小者，澄粉甚白腻，须深掘二、三尺乃得正根。江西人栽之沃土，取根作蔬食，
味如山药。

(Recorded in the Middle Category of *Shennong Bencao Jing*)
**Names:** Tugua (from *Shennong Bencao Jing*), Gou KT (annotated by Guo Pu), Laoya Gua (from *Tujing*), Ma Gua (pronounced Bao), Chibaozi (from *Yanyi*).
Su Song states: The *Liji · Yueling* records, "In the fourth month, Wanggua grows." This refers to this plant. People in Junzhou and Fangzhou call it Laoya Gua, also known as Tugua. According to *Erya*, " , which is Tugua." Guo Pu annotates, "Resembles Tugua." However, Tugua calls itself KTgu, also named Gou KT; thus, Tugua is a different entity.
It is further stated: Wu, Fei. Also called Tugua. This is another entity, not the local Tugua. There are many instances of different species sharing the same name, which must be distinguished carefully.
Li Shizhen says: Tugua, its root possesses the nature of earth, and its fruit resembles a melon. Some say the root tastes like a melon, hence the name Tugua. The meaning of the character "Wang" is unknown. The melon resembles hailstones; when ripe, its color turns red, and crows like to eat it, hence the common names Chibao and Laoya Gua. Under one leaf there is one tendril, so the folk call it Gonggongxu. This parallels the naming of Rehmanniae Radix Praeparata seedlings as Poponai, forming a couplet.
**Collection and Explanation:** *Mingyi Bielu* states: It grows in the flat marshy fields of Lu and between house walls. The roots are harvested in the third month and dried in the shade.
Tao Hongjing says: Currently, Tugua grows among fences and courtyards. When the fruits ripen, they are red like bullet-shaped seeds. Its roots are not used in major prescriptions, only singly in small doses. Zheng Xuan’s annotation of *Yueling*: "In the fourth month, Wanggua grows," identifying it as Smilax glabra, is significantly erroneous.
Su Gong says: In the fourth month, vines grow and spread; the leaves resemble those of Trichosanthes kirilowii, round without lobes or notches, with hairs and spines. In the fifth month, yellow flowers bloom. Below the flowers form fruits like bullet-shaped seeds, green when raw and red when ripe. The root resembles Puerariae Radix, thin and starchy, called Tugua Gen. Those from the north have fruits linked together, large as dates, with yellow skin and white flesh. The seedlings and fruits are similar, but the root structures differ. For treating jaundice and breaking blood stasis, the southern variety is superior.
Kou Zongshi says: Wanggua has a shell about one inch in diameter and two inches long, slightly round at the top and pointed at the bottom, ripening in the seventh and eighth months with a reddish color. The seeds inside resemble mantis heads, now called Chibaozi by people. Its root is indeed Tugua Gen. On the fine roots, pale yellow roots grow again, three to five connected, about the thickness of a thumb. Both root and fruit are used medicinally.
Li Shizhen says: Wanggua sprouts in the third month; its vines have many tendrils and can be eaten when tender. The leaves are round like horse hooves with pointed tips, green on the surface and pale underneath, astringent and not glossy. Flowers bloom in the sixth and seventh months, clusters of five-petaled small yellow flowers. Fruits hang in clusters, ripening in red and yellow colors, with rough and astringent skin.
However, resembling the smaller roots of Trichosanthes radices, the clarified starch is very white and fine. One must dig two or three chi deep to obtain the true root. People in Jiangxi cultivate it in fertile soil and use the root as a vegetable, tasting like Dioscoreae Rhizoma.
**Root**
**Flavor and Nature:** Bitter, cold, non-toxic. Li Quan says: Neutral.
Chen Cangqi says: Slightly toxic, can induce vomiting and purging. Its juice is used to refine Realgar and Mercury.

Treating epidemic febrile diseases, wine jaundice, severe heat with restlessness, chronic deficiency heat, discharging pus, resolving traumatic blood stasis, breaking masses and accumulations, inducing abortion (*Tang Bencao*). Mainly treating gu poison, pediatric flash accumulation, distension and phlegm-malaria. All involve crushing the roots and leaves for juice, taken in small amounts to induce vomiting or purging (Chen Cangqi). Promoting urination and defecation, treating dark complexion and facial sores (Li Shizhen).
