治风愈疮，或即此欤。
治太阳头疼，目昏眩。

《桂海草木志》记载：叶子像冬青。《粤志》记载：肇庆七星岩出产风药，丛生在石缝中，它的叶子圆而浓密，和酒一起嚼食，可以治疗风疾。一种叫风草，一种叫风菜。谚语说：“风病须用风菜”，指的就是这种植物。按：《福宁府志》记载：风藤草又名山膏药，能治疗风症和疮疡，或许就是这种植物吧。
（该药）治疗太阳头疼（足太阳膀胱经受邪引起的头痛），眼睛昏花眩晕。
这就是獐耳草，香气胜过细辛。
治疗因过度劳累导致的虚弱发黄。（出自汪氏方剂）
产于云南，少数民族地区有很多人售卖它。普通人如果被情欲禁锢闭塞，往往会导致死亡。得到这种草的一茎煎服后，入口即豁然开朗，如同从梦中醒来，断绝缘分、消除爱恋，自己也不知道为什么会这样。按：段成式《杂俎》记载左行草能使人没有感情，范阳用它进贡，或许就是这一类。又有合情草，与它作用相反，可知造物主生成万物，必然有相对待的道理如此。
已经相思，断绝情爱，灵验如神。
这就是合情草。《柳崖外编》记载：永昌府澜沧江以外，有一种和合草，根洁白，结成男女交媾的形状，当地人见到它，用稻米在周围围起来挖掘，才能得到，否则它就会遁去。有夫妇关系不和谐的，服用它就能欢好。然而装在江船上，就会沉溺无法渡河。聪明人用长线系住放在岸边，拿着线登上船，渡河完毕后，然后再拉过来。所以云南省边境一带，时常有这种草。听说服用的人说：男人看女人，即使是丑妇嫫母，也不如西施、王嫱；女人看男人，即使是丑陋的也像潘安，即使是年老也像健壮男子。
治疗夫妇互相憎恶的疾病，煎酒后服用。
《药性考》记载：这两种都产于北直隶的咸地，当地人割取它们，烧成灰后用汤水淋滤，煎熬得到盐，它们的叶子像蒿草一样圆长。到了秋天，茎叶都变红，烧成灰煎盐，胜过用海水煮制的。
味道咸，性质凉，能清热消积。
*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.
