The shape resembles *Tu'ercao* (Lagotis glauca), growing flat against the ground with leaves. The upper surface is pale green, and the lower surface is slightly white, with visible veins. The margins are fringed with yellow hairs, appearing velvety and golden in color. When first sprouting, it is most abundant on mountains.

It has a sweet and bland taste and treats hemoptysis caused by deficiency consumption (Xu Lao).

Wang Lianshi's *Herbal Formulas*: It is also known as *Chuandiling*, used to treat bruises and traumatic injuries.

It climbs and grows in fields and among mountain rocks. The leaves resemble those of *Sanjiaofeng*, smooth and glossy with a bluish-yellow hue. The root is named *Jinxian Diao Xiama*, also called *Dujio Chan Chu* or *Jinxian Chonglou*. It is used in *Zhunsheng Dou Du Fang*, but it is not the *Caoheche* or *Zaoxiu* mentioned in *Bencao Gangmu*. *Danfang Bencao* records: *Jinlingcao*, also known as *Gua Jin Teng* or *Jinxian Diao Xiama*. Its fruit resembles a bell; when the stem is broken, the exuded juice looks like milk. This natural juice is used to fix realgar and process sulfur; its frost-like residue can be used to refine arsenolite and process mercury. *Baicao Jing* records: *Jinxian Diao Hamo* grows in mountain soil. The stems are red and slender, the roots are large, and the leaves resemble those of *Jinsuo Shi*. It flowers during the Mangzhong solar term, resembling *Gujinghua*. The roots are harvested for medicinal use.

Note: *Fangji* (Stephaniae Tetrandrae Rhizoma) is similar to this plant, but the root shape does not resemble a toad, the stem is not very purple, the leaves are not very round but have pointed lobes, and the spider-web-like patterns on the leaves are indistinct. These features serve as distinctions. *Caobao* records: *Jinxian Chonglou* grows at the foot of shady mountains. The root has tubercles and resembles a toad. It does not penetrate deep into the soil and is easy to dig up. Its nature is cool, and it is an emetic. Sprouts appear around the Xiaoman solar term, spreading with purple stems. The leaves do not grow opposite each other, resembling *Huanglong Teng* but softer, with very distinct spider-web patterns on the leaves. If the leaves are not round but slightly pointed, the patterns are indistinct, the stem is not very purple, and the shape does not resemble a toad, it is *Fangji*, not *Chonglou*. Wang Lianshi's *Herbal Formulas* record: Those with red lines are *Jinxian Diao Xiama*, while those with green stems are *Han Fangji*. Wang Shengyu states: The root of *Chonglou* resembles a three-legged toad, with additional root knots resembling toads branching off. In old plants, digging up one specimen may reveal dozens of roots beneath, with toad-shaped roots hanging horizontally; these possess the greatest potency. Zhao Gongzai says: Fresh *Jinxian Diao Xiama* has greater potency than dried specimens. Since it causes inevitable vomiting due to its toxicity, people often fear and avoid using it. However, after vomiting, the illness disappears as if lost, and the toxin is internally resolved. For carbuncles on the back where toxic heat attacks the heart, this herb is essential. However, for minor toxins, it must absolutely not be used because its potency is too strong for mild conditions. Mismatched potency leads to adverse effects from excessiveness.

Its nature is neutral, and its taste is bitter. It reduces abscesses, dispels wind, and resolves toxicity. *Baicao Jing* records: The root is cool in nature, helps expel pus from sores, disperses swelling and toxicity, and treats scrofula. It is a sacred medicine for external diseases. *Caiyao Zhi* records: It treats appendicitis (Chang Yong), dispels wind, and defeats toxicity. *Ge Zu Fang* records: It induces vomiting of phlegm and saliva, preferably combined with *Gua Di* (Melon Stalk). *Bianque Xin Shu* records: *Jinxian Chonglou*, commonly known as *Jinxian Diao Xiama*. After harvesting, remove the outer black skin, crush with a stone mortar (avoiding iron tools), dry, and powder. Store in a small porcelain bottle. For any condition requiring the expulsion of phlegm and saliva, combining it with *Gua Di* is best. For wind-phlegm binding in the chest, take 1 qian mixed with Yin-Yang water. For cold damage progressing to malaria, take 1 qian with plain water on an empty stomach just before an attack. For dysentery with inability to eat (Jinkou Li), take 1 qian with cold water. Avoid iron tools.

For falls and trauma: Zhang Family's transmitted formula: Crush the root to extract juice, mix with wine for oral administration, and apply the dregs externally.

The leaves are named *Tiangaoyao*: Applied to swollen, toxic, and ulcerated areas, it draws out toxins and promotes wound closure. Cooked and applied to toxic swellings, it draws out toxic fluids. Taken orally after decoction in wine, it treats heart pain. Ground in water and applied topically, it treats hemorrhoids. Decocted into a plaster, it treats various diseases. Wang Lianshi's *Herbal Formulas* record: *Tiangaoyao* treats hard carbuncles, malignant toxins, and flowing deposits. Combined with *Dushu* and raw wine, crushed and taken orally, it has significant detoxifying effects, though ingestion may cause vomiting and diarrhea.
