(Burn to remove the bad odor, eliminate epidemic diseases. According to the "Story of Emperor Wu of Han," when the Queen Mother of the West descended, Emperor Wu burned the powder of *Douxuxiang* (兜木香). *Douxuxiang* was a tribute presented by the Douqu Kingdom; it is as large as a soybean. When applied to palace gates, its fragrance could be smelled for a hundred *li*. During a severe epidemic in the Guanzhong region, where corpses were piled upon one another, burning this incense stopped the plague. The "Inner Biography" states that the dead revived. This is a spiritual incense, not produced in China; marking its efficacy, it is regarded as the chief among herbs.)

Pungent in flavor, neutral in nature, non-toxic. It primarily resolves various drug poisonings. In Lingnan and between Mozhou and Wuzhou, if poisoned by toxic plants, both this herb and *Qianjinteng* (千金藤) can detoxify it. It also treats gu poison, stream poison, malignant thorns, injuries from tigers, wild wolves, and venomous snakes or insects, as well as epidemic malaria, miasma-induced alternating chills and fever, cough with profuse phlegm, feishi (flying corpse disease), throat obstruction, abscesses and swelling, pediatric chills and fever, erysipelas, sudden evil qi invasion, zhuwu (possession-like ailments), and bloody dysentery. All should be taken as a decoction. Its efficacy is comparable to rhinoceros horn, hence the name "Caoxi" (Grass Rhinoceros), being most proficient in detoxification. It grows in Quzhou, Wuzhou, Hongzhou, and Raozhou. The plant is two to three chi tall, with a single stem; the root resembles *Xixin* (Asarum), and powdered administration is more effective. Those growing in water are named "Muxi" (Wood Rhinoceros). Sea Medicine records state: According to the "Guangzhou Records," it grows in Lingnan and the sea. It has a single stem and opposite leaves, resembling *Dengtaicao* (Lampstand Grass) or *Xixin*. Neutral in nature, non-toxic. It resolves all types of toxic vapors, injuries from tigers and wild wolves, and stream poisons or wild gu. It is best burned, powdered, and ingested; those near death who take it may survive.

(Sweet in flavor, cold in nature, non-toxic. Long-term consumption prevents hunger, harmonizes the middle jiao, and promotes urination and bowel movements. It grows by the water, with leaves resembling duckweed. The "Erya" states: "Wei" refers to drooping. The "Sanqin Ji" states: Boyi and Shuqi ate it for three years without changing their complexion. King Wu admonished them, and they died refusing to eat it. The "Guangzhi" states: Wei leaves resemble duckweed, are edible, and benefit people. Sea Medicine records state: According to the "Guangzhou Records," it grows in seas, ponds, and marshes. The commentary on the "Erya" notes: "Wei" is an aquatic vegetable. It promotes water passage, reduces edema, and moistens the large intestine.)

The head resembles a marble, the tail like a bird's tail; the two halves open and close and shake automatically upon seeing people, hence the name "Wufeng Duyao Cao" (Windless Swaying Grass).
