仲景治发汗吐下后，虚烦不得眠，若剧者，必反复颠倒，心中懊 ，栀子豉汤治之。
虚，故不用大黄，有寒毒故也。栀子虽寒无毒，治胃中热气，既亡血、亡津液，腑脏无润养
，内生虚热，非此物不可去，张仲景《伤寒论》已着。又治心经留热，小便赤涩，去皮山栀
子、火炮大黄、连翘、甘草炙，等分，末之，水煎三二钱匕，服之无不效。
二书所说甚详，今人又取尖长者入药，言其快锐速效，屡尝试之，果如其说。
其色如今之醮晕线，上半白，下半肉红，散垂如丝，为花之异。其绿叶至夜则合，
又谓之夜合花。陈藏器、日华子皆曰皮杀虫，又曰续筋骨。经中不言。
此秦地所生者，故言秦椒。大率椒株皆相似，秦椒但叶差大，椒粒亦大而纹低，不若
蜀椒皱纹高，为异也。然秦地亦有蜀种椒，如此区别。
所在山谷皆有之，然未尝于平陆地见也。叶绝少，其茎黄褐色，若柏皮，三面如锋刃
，人家多燔之遣祟。方家用之亦少。
今蔓延而生，谓之为草。又有木身，谓之为木。又须物而上。然干不逐冬毙，亦得木
之多也，故分入木部为至当。唐白乐天诗∶“有木名凌霄，擢秀非孤标。”由是益知非草也
。《本经》又云∶“茎叶味苦。”是与瞿麦别一种甚明。《唐本·注》云∶“且紫葳、瞿麦
皆《本经》所载，若用瞿麦根为紫葳，何得复用茎叶？”此说尽矣。然其花赭黄色，本条虽
不言其花，又却言茎叶味苦，则紫葳为花，故可知矣。
张仲景治疗经过发汗、催吐或泻下之后，出现虚烦不得安睡的症状，如果病情严重，必定会翻来覆去，心中烦闷懊恼，用栀子豉汤治疗。
因为属于虚证，所以不用大黄，是因为体内有寒毒的缘故。栀子虽然性寒但无毒，能治疗胃中的热气，既然已经失血、津液枯竭，脏腑失去滋润滋养，内生虚热，非此药不能去除，这一理论在张仲景的《伤寒论》中已有记载。另外还能治疗心经残留的热邪，导致小便颜色深红且排尿涩痛，取去皮的山栀子、火炮制的大黄、连翘、炙甘草，各等分，研成细末，每次用水煎服三二钱匕，服用后没有不生效的。
这两本书（指《伤寒论》及其他本草著作）所述非常详细，现在的人又选取尖端较长的栀子入药，说它药效迅猛锐利、见效快，多次尝试验证，果然像所说的那样。
栀子的颜色就像现在的祭祀晕圈线一样，上半部分白色，下半部分肉红色，散开下垂如同丝线，是花朵中的奇异品种。它的绿叶到了夜晚就会闭合，所以又被称为夜合花。陈藏器、日华子都说其皮能杀虫，又能接续筋骨。但在经典本草著作中没有提及这一点。
这是秦地所生长的花椒，所以说它是秦椒。大抵花椒植株都相似，秦椒只是叶子稍大一些，花椒颗粒也较大且表面皱纹较浅，不像蜀椒那样皱纹高耸，这就是它们的差异之处。然而秦地也有种植蜀种的椒，需要这样加以区分。
这种植物所在的山谷中都有生长，但是从未在平坦陆地上见过。叶子极少，茎秆呈黄褐色，像柏树皮一样，三面都像刀刃一样锋利，人们多焚烧它用来驱除邪祟。中医方剂中使用它也很少。
现在它蔓延生长，被称为草。又有木质化的主干，被称为木。而且必须依附其他物体向上攀爬。然而它的枝干不会随着冬天而枯死，也具有树木的特性，所以将其分类归入木部是最恰当的。唐代白居易的诗中说：“有一种树名叫凌霄，拔萃秀出并非孤高无依。”由此更加知道它不是草本植物。《神农本草经》又说：“茎叶味道苦。”这与瞿麦是两种不同的东西是非常明显的。《新修本草·注》中说：“况且紫葳、瞿麦都是《神农本草经》所载的药物，如果用瞿麦的根当作紫葳，为什么又要再用它的茎叶呢？”这个说法非常完备。然而紫葳的花是赭黄色的，本条虽然没直接说它的花，却又提到茎叶味苦，那么可以推断紫葳是以花入药的，因此可以知道了。
Zhang Zhongjing treated the condition of empty irritability and inability to sleep following sweating, vomiting, or purging. If severe, it would inevitably involve tossing and turning with a feeling of stifling restlessness in the heart, which was treated with Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction).
Because it is a deficiency pattern, Dahuang (Rhubarb) is not used, as there is cold toxicity present. Although Zhizi (Gardenia Fruit) is cold in nature but non-toxic, and treats heat qi in the stomach, since blood and body fluids have been depleted, leaving the viscera without nourishment and generating internal empty heat, only this herb can eliminate it. This has already been documented in Zhang Zhongjing's Shanghan Lun (Treatise on Cold Damage). It also treats residual heat in the Heart channel, causing dark red and difficult urination. One takes Zhizi (Gardenia Fruit) with skin removed, Dahuang (Rhubarb) processed by fire, Lianqiao (Forsythia Fruit), and Gancao (Licorice Root) roasted, all in equal parts, ground into powder. Take three or two qianbi (ancient measure) boiled in water; administration is invariably effective.
These two texts describe this in great detail. Nowadays, people select the longer, pointed Zhizi for medicinal use, claiming its effects are rapid and sharp. Repeated trials confirm this assertion.
Its color resembles the halo lines used in modern rituals: white on the upper half and flesh-red on the lower half, scattering and hanging down like silk threads, making it an unusual flower. Its green leaves close at night, so it is also called Yehe Hua (Night-Closing Flower). Chen Zangqi and Ri Huazi both stated that the bark kills parasites and heals bones and tendons. However, this is not mentioned in the classic materia medica.
This species grows in the Qin region, hence referred to as Qin Jiao (Qin Pepper). Generally, pepper plants are similar; Qin Jiao merely has slightly larger leaves, and its peppercorns are larger with shallower wrinkles, unlike Shu Jiao (Sichuan Pepper) which has high wrinkles. This is the difference. Nevertheless, the Qin region also cultivates Shu-type peppers, requiring such distinction.
It is found in valleys everywhere, yet never seen on flat land. Its leaves are extremely scarce. The stem is yellowish-brown, resembling cypress bark, with three edges like blades. People often burn it to dispel evil influences. It is rarely used in medical formulas.
Currently, it spreads and grows, being called a herb. Yet it has a woody trunk, being called a tree. Furthermore, it must climb upon other objects. However, its stems do not die off in winter, possessing many characteristics of trees; thus, classifying it under the Wood category is most appropriate. Bai Juyi of the Tang Dynasty wrote in his poem: "There is a tree named Lingxiao, rising elegantly, not standing alone." From this, it is further known that it is not a herb. Ben Jing (Shennong Ben Cao Jing) also states: "The stems and leaves taste bitter." This clearly distinguishes it from Qumai (Dianthus Herb). Tang Ben Zhu (Xinxiu Bencao Commentary) states: "Moreover, Ziwei and Qumai are both recorded in Ben Jing; if one were to use Qumai root as Ziwei, why would one then use the stems and leaves?" This argument is conclusive. However, Ziwei flowers are ochre-yellow. Although the main entry does not explicitly mention its flowers, it mentions the bitterness of stems and leaves, implying that Ziwei is utilized for its flowers, which allows us to conclude this.
