*Guanghai Caomu Zhi* (Record of Plants and Trees in the Guangxi Region) records: The leaves resemble those of *Ilex chinensis* (Dongqing). *Yue Zhi* (Records of Guangdong) states that Feng Yao is produced at Qixing Rock in Zhaoqing, growing in clusters within rock crevices. Its leaves are round and dense; when chewed with wine, it treats wind diseases (diseases caused by wind pathogens). It is known as one name "Feng Cao" (Wind Grass) and another "Feng Cai" (Wind Vegetable). The proverb says, "For wind disease, one must use Wind Vegetable," referring to this plant. Note: According to *Funing Fu Zhi* (Gazetteer of Funing Prefecture), Feng Teng Cao (Wind Vine Grass) is also called Shan Gao Yao (Mountain Plaster Medicine), treating wind syndromes and sores; it might be this same plant.

(It treats) Taiyang headache (headache due to pathogenic invasion of the Foot-Taiyang Bladder channel), blurred vision, and dizziness.

This is Zhang Er Cao (Deer-Ear Grass), with an aroma surpassing that of *Asari Radix et Rhizoma* (Xixin).
It treats deficiency yellowing resulting from overexertion (from Wang's Formula).

Produced in Yunnan, where many ethnic minorities sell it. Ordinary people whose emotions and desires are blocked and constrained often face death. By decocting and ingesting a single stem of this herb, one feels instantly enlightened upon entering the mouth, as if waking from a dream, severing attachments and eliminating love, unaware of why this occurs. Note: Duan Chengshi’s *Zazu* records that Zuoxing Cao (Left-Walking Grass) renders people emotionless, and Funyang offered it as tribute; it may belong to this category. There is also Heqing Cao (Harmony-Qing Grass), which has the opposite effect, demonstrating that the Creator’s generation of all things necessarily involves complementary opposites.

Already experiencing lovesickness, it severs romantic attachments, proving efficacious as if by divine power.

This is Heqing Cao. *Liuya Waibian* (External Compilation of Liuya) records: Beyond the Lancang River outside Yongchang Prefecture, there is a Hehe Cao (Union Grass) with white roots shaped like copulating man and woman. Locals, upon seeing it, dig around it enclosing it with rice grains to retrieve it; otherwise, it vanishes. Couples with discordant relationships take it to restore harmony. However, when transported on riverboats, it causes sinking and prevents crossing. Wise individuals tie it with a long line, place it on the shore, board the boat holding the line, and after crossing, pull it across. Thus, near the border regions of Yunnan Province, it is occasionally available. Those who have taken it report: A man viewing a woman considers even an ugly woman like Momo inferior to Xi Shi or Wang Qiang; a woman viewing a man considers even an ugly man like Pan An, and an old man like a vigorous youth.
It treats mutual aversion between husband and wife, administered as a decoction in wine.

*Yaoxing Kao* (Examination of Drug Properties) states: Both varieties grow in saline soils of Zhili. Locals harvest them, burn them to ash, leach the ash with water, and boil down the liquid to obtain salt. Their leaves resemble mugwort, being round and elongated. In autumn, stems and leaves turn red; salt obtained by burning and boiling is superior to that boiled from seawater.
Taste: Salty. Nature: Cool. Actions: Clears heat and resolves accumulation.
