（唐本草）
【气味】甘平，无毒。
【主治】主明目，止泪，疗泄精，去臭恶气，伤寒头痛，上气。
【核】曰∶薰香草，一名蕙，与莸反。南越人谓之燕草。宋开宝谓之零陵香。出零陵山
谷，湖、广诸州皆有，多生下湿地。入春宿根再发，叶如罗勒，又似麻叶，两两相对。七月
开花，八月收刈，可 可佩，可荐可熏。虽至枯槁，香犹芬馥。山海经云∶浮山有草，麻叶
而
方茎，赤华而黑实，气如蘼芜，可以已疠。尔雅翼云∶盖能去恶臭，令身香，故古之祓除，
以此草熏之，所以降神也。埤雅云∶凡气熏则惠和，曝则酷烈。故于文蕙草为惠，近世皆指
菅茅一干数花者为蕙，一干一花者为兰。即诗书家亦多引用，竟不知是为何草，徒尚其名而
迷其实，皆此类也。离骚辨证云∶古之兰蕙，花叶俱香，燥湿不变；今之兰蕙，花萼虽香，
干则腐臭，兰唐蕙圃，受诬久矣。
先人云∶赤华有通神之德。黑实具幽隐之情。肾药而得心用者也。乃能交精神。散寒风。

【 】曰∶天子鬯，诸侯薰。鬯用灌，薰以香自烧。故薰谐熏，熏者火烟上出也。顾藏
真之自下而上者，肝木春生之气耳。是主春气者病在头，不能积续以升，致上下失于敌应者
相宜。观鱼涉负水，则知下上之为义矣。

（《唐本草》记载）
【气味】味甘，性平，无毒。
【主治】主要治疗明目、止泪、疗治泄精、去除恶臭之气、伤寒引起的头痛以及气逆上冲。
【考证】曰：薰草是香草，又名蕙，与莸草相反。南越人称之为燕草。宋代开宝年间称为零陵香。出产于零陵的山谷中，湖南、湖北等州都有生长，多生于低湿之地。入春后宿根再次发芽，叶子像罗勒，又有点像麻叶，两两相对。七月开花，八月收割，可以佩戴，也可以铺垫或熏香。即使干枯了，香气依然芬芳浓郁。《山海经》说：浮山有一种草，叶子像麻，茎是方形的，开红花结黑籽，气味像蘼芜，可以用来治疗疠风。《尔雅翼》说：这种草能去除恶臭，使身体芳香，所以古代举行祓除仪式时，用这种草来熏蒸，以此降神。《埤雅》说：凡是气息熏蒸则温和仁爱，暴晒则酷烈猛烈。所以在文字构造上，“蕙”字通“惠”。近代人都指那种一茎多花的为蕙，一茎一花的为兰。即使是《诗经》《尚书》的研究者也多引用此名，竟然不知道它到底是什么草，只是崇尚其名而迷失了其实际形态，都是这类情况。《离骚辨证》说：古代的兰和蕙，花和叶都香，无论干燥还是潮湿都不改变；现在的兰和蕙，虽然花萼香，但干燥后就腐臭，兰花在唐代、蕙花在圃中，被诬陷已久。
先父说：红色的花具有通达神灵的美德。黑色的果实蕴含幽深隐秘的情感。这是肾药却具备心的功用，能够交合精神，散发寒风，通达……
【按语】曰：天子饮用鬯酒，诸侯使用薰草。鬯酒用于灌注，薰草通过燃烧散发香气。所以“薰”通“熏”，熏是指火烟向上冒出。顾藏真认为从下往上生的，是肝木春季生发的气机。既然是主管春气的病证表现在头部，不能积聚延续以升发，导致上下失去呼应，这就适宜采用这种方法。观察鱼涉水背负水，就知道上下之间的义理了。

[Flavor and Properties] Sweet, neutral, non-toxic.
[Indications] Primarily treats brightening the eyes, stopping tearing, curing seminal emission, removing foul odors, headache caused by cold damage (Shanghan), and rebellious qi ascending.
[Textual Research] It is stated: Xuncao is a fragrant herb, also known as Hui, which is opposite to You. People in Nan Yue call it Yanc grass. In the Kaibao era of Song Dynasty, it was called Linglingxiang. It grows in the valleys of Lingling, and is found in various prefectures of Hunan and Hubei, mostly in low-lying wetlands. After entering spring, the perennial roots sprout again; the leaves resemble Ocimum basilicum (Basil) or Cannabis sativa (Hemp leaf), growing pairwise. It flowers in July and is harvested in August; it can be worn as an ornament, used for bedding, or burned for fumigation. Even when dried and withered, its fragrance remains rich and lingering. *Classic of Mountains and Seas* states: On Fu Mountain, there is a herb with hemp-like leaves and square stems, bearing red flowers and black fruits; its scent resembles Miju, and it can cure leprosy (*Li*). *Erya Yi* states: This herb can remove foul odors and make the body fragrant; therefore, in ancient purification rituals, this herb was used for fumigation to invoke deities. *Pi Ya* states: When scented by smoke, the aura becomes gentle and benevolent; when exposed to sun, it becomes harsh and fierce. Thus, in character etymology, "Hui" (orchid/fragrant herb) shares the meaning with "Hui" (benevolence). In recent times, people generally refer to plants with multiple flowers on one stem as Hui, and those with a single flower per stem as Lan (Orchid). Even scholars of *Shijing* and *Shujing* often cite these names without knowing what specific herb they refer to, merely valuing the name while losing track of the reality, which is typical of such cases. *Lisao Bianzheng* states: In ancient times, Lan and Hui were fragrant in both flowers and leaves, unchanged by dryness or humidity; in modern times, although their calyces are fragrant, they become putrid when dried. Lan has been slandered since Tang Dynasty, and Hui in gardens has long been wronged.
My late father said: Red flowers possess the virtue of connecting with spirits. Black fruits embody the sentiment of hidden depths. This is a kidney herb that utilizes heart function, capable of harmonizing spirit and mind, dispersing cold wind, and achieving...
[Commentary] It is said: The Son of Heaven drinks Chang wine, while feudal lords use Xuncao. Chang wine is poured, whereas Xuncao is burned to emit fragrance. Therefore, "Xun" corresponds to "Xun" (fumigate/smoke), where Xun refers to fire smoke rising upward. Gu Zhenzhen considered that rising from below to above is the Qi of Liver Wood generating in Spring. Since diseases governed by Spring Qi manifest in the head, if the Qi cannot accumulate and ascend continuously, causing a lack of correspondence between upper and lower parts, this method is appropriate. Observing fish swimming through water carrying water helps understand the principle of upper and lower interactions.
(Mr. Wang Shaolong once said that the initial generation of Shaoyang Qi is like the initial emergence of incense smoke: light, void, floating, upright, and long. Therefore, in the first pentad of Start of Spring, it is named Fish...)
