[Cang'er (Xanthium Fruit)]
Pungent, neutral. Primarily treats gu poison (parasitic disease). Also treats malignant sores caused by various poisons from snakes, vegetables, and meat. Grows in mountain valleys.
Indigo fades and does not remain constant; green is pushed to treat skin affections. Burned marks turn green after rain. Light remains after the rain. Insect stench and filth, ulcerous toxic dirt are cleared of all filth. There is healing without fault.
*History of the Northern Dynasties* records: "Green comes from indigo, indigo yields to green." The teacher has no fixed form, residing in understanding the classics. Famous doctors say: one name is Tuiqing (Pushing Green). *Analects* states: "Complaints of skin affections do not take effect."
Monk Huichong's poem: "Spring enters burned marks turning them green." Tang Qiu's poem: "Green after rain in Wushan." *Records of Wei* records: Sima Lang clears away filth. *Book of Tang* records: Will the common people of the world perhaps recover?

[Ganjiang (Dried Ginger Rhizome)]
Pungent, warm. Primarily treats chest fullness, cough, and rebellious qi rushing upward. Warms the middle jiao, stops bleeding, induces sweating, expels wind-damp bi- obstruction, and treats diarrhea with loose stools. Raw use is especially effective. Long-term consumption removes bad breath and clarifies the mind-spirit. Grows in river valleys.
Musk-like odors are swept away thoroughly; flavors are harmonious and adjusted. Tender tips shine brightly in the sun; old ginger stands proud like frost, pungent. Pungency compares to Guizhi (Cinnamon Twig); moisture-resisting power divides with Jiaozhi (Zanthoxylum Fruit). Offering sweetness is not the intention; snowing slander elevates the spirit.
Zhang Heng's fu: "Su Zi Jiang, sweeping away musky odors." *Lüshi Chunqiu*: "The most harmonious flavors are Yangpu's ginger." Liu Zi's poem: "Shining in the sun like emptiness."

Mei Yaochen's poem: "Offering pungency, not sweetness; this meaning should be sought independently." Zhu Xi's poem: "Ginger is said to harm the heart; who can clear this slander? Let us discuss its ability to remove filth; see the mind-spirit clearing at dawn."

[Cang'er (also known as Huxi, Di Kui)]
Sweet, warm. Primarily treats cold-pain in the head-wind, wind-damp bi- obstruction throughout the body, spasmodic pain in the four limbs, malignant flesh and dead muscle. Long-term consumption tonifies qi, makes ears and eyes bright, strengthens will, and lightens the body. One name is Huxi; another is Di Kui. Grows in river valleys.
Eating for longevity through ears; seeking its humble quality. Vines extend and hang down; clusters form densely. Thinly gathered in small baskets, separated filling rooms. Putting down chopsticks forgets hunger; vaguely resembling slave oranges.
*Shiji Nianbiao*: "This is no different from eating with ears." *Jinshu* records: "Seeking the beauty of marriage matchmakers, discussing the humble quality of sand and gravel."
