安五脏以益心脾。智足神充。功能夜合。味甘平而蠲忿怒。调营止痛。力主中和。（
合欢一名乌树。又名夜合。其树如枸橘形。叶如皂荚叶。至夜即合。用皮用花。各随所便。
皮可行皮。花能养血。甘平之性。入脾胃。长肌肉。续筋骨。补而不滞。益神智。蠲忿怒。
毕竟无甚治功。至于不寐一证。各有成病之由。不可因其有夜合之名而滥用之也。）
\r秦皮\pq72a1.bmp\r
味苦气寒。色青性涩。主少阳协热之痢疾。逐水行皮。洗厥阴湿火之阳邪。祛风明目
。（秦皮浸水色青。书纸不落。且不沾水。故入肝胆二经。以其性寒也。故专清肝胆之湿火
。其主治一切之病。皆由肝胆湿火所致。至能益精者。亦邪热去则精自益耳。）
\r西河柳\pq72a.bmp\r
性温。味属甘咸。透发痧疹。具宣表松肌之力。化毒功归脾胃。浴除风痒。有解酒
利便之功。（西河柳。此柳遇天之将雨。望之必有郁蒸之气以应之。味甘咸。微温。入脾胃
。行肌肉。通肢节。故能透发痧疹。蠲除风痒。皆在用之者取意耳。）
\r榆白皮\pq72.bmp\r
皮能入肺。性粘滑导滞通肠。榆令人瞑。味甘平和脾消水。（榆白皮性极粘滑。故
香作用之。胜于胶漆。其性甘平无毒。入脾胃。利二肠。滑胎导滞。无非皆取滑利之功。然
下降之物。不可因稽康有榆令人瞑一语而服之。其意不过欲令人之心神。如此物胶粘之状方
可耳。即观其合欢蠲忿。萱草忘忧。岂以二物服之。果能蠲忿忘忧乎。考榆白皮之性。甘平
无毒。毕竟非攻伐之品。故古人有榆羹榆面等服食诸法。可以充饥。可以辟谷。然其滑降之
性多。恐耗津液耳。）
安五脏以益心脾。智足神充。功能夜合。味甘平而蠲忿怒。调营止痛。力主中和。（
合欢又名乌树，又名为夜合。其树干形状如同枸橘，叶片类似皂荚叶，到了夜晚叶子就会闭合。使用树皮或花朵，均可根据方便选用。
树皮能作用于体表皮肤，花朵能够养血。其味甘、性平，归入脾胃经，能促进肌肉生长，接续筋骨，补益而不滋腻滞塞，有益于心神智慧，能消除愤怒情绪。
但毕竟没有特别显著的治疗功效。至于失眠这一病症，各有导致生病的原因，不能因为其有“夜合”的名字就滥用它。）
秦皮
味苦，气寒，色青，性涩。主治少阳经协同热邪所致的痢疾，逐水行于皮表；清洗厥阴经湿火之阳邪，祛风明目。
（秦皮浸泡水中颜色变青，书写纸张不脱落，且不沾水，所以进入肝胆二经。因其性寒，所以专门清除肝胆的湿火。其所主治的各种疾病，多由肝胆湿火引起。至于它能益精，也是因为邪热去除后精气自然恢复的缘故。）
西河柳
性温，味属甘咸。具有透发痧疹的作用，具备宣散表邪、松解肌腠的力量。化解毒功归于脾胃，洗浴可去除风痒，有解酒、利小便的功效。
（西河柳，这种柳树在天气将要下雨时，望去必有郁蒸之气与之相应。味甘、咸，微温，入脾胃经，运行于肌肉，通达肢节，所以能透发痧疹，消除风痒，这都是使用者取其意蕴罢了。）
榆白皮
树皮能入肺经，性质粘滑，能导滞通肠。榆树令人昏睡（注：此处指古人误解），味甘、平和脾消水。
（榆白皮性质极其粘滑，所以作为胶漆使用效果胜过真正的胶漆。其性甘平无毒，入脾胃经，利大小肠，滑胎导滞，无非都是取用其滑利之功。然而这是下降性质的药物，不可因为嵇康有“榆令人瞑”的一句话就服用它。他的本意不过是希望人的心神像这种物体胶粘的状态一样安宁而已。就像看合欢能消除愤怒，萱草能忘记忧愁，难道吃了这两种东西，真的就能消除愤怒、忘记忧愁吗？考证榆白皮的药性，甘平无毒，毕竟不是攻伐类的药材，所以古人有榆羹、榆面等服食方法，可以充饥，可以辟谷。但其滑降的性质较多，恐怕会耗伤津液。）
To calm the five Zang organs and benefit the Heart and Spleen. Wisdom is sufficient, spirit is abundant. Its function is to close at night. The taste is sweet and neutral, eliminating anger. Regulating Ying (nutritive Qi) and stopping pain. It strongly emphasizes harmony and neutrality. (
Hehuan (Albiziae Cortex/Flos), also known as Wushu (Black Tree), or Yehe (Night-Closing). Its trunk shape is like that of Citrus trifoliata (Wuchangju), leaves resemble those of Gleditsia sinensis (Zaojia), and they close at night. The bark or flowers can be used according to convenience.
The bark acts on the skin surface, while the flower nourishes Blood. With a sweet and neutral nature, it enters the Spleen and Stomach channels, promotes muscle growth, connects bones and tendons, tonifies without causing stagnation, benefits the spirit and wisdom, and eliminates anger.
However, it ultimately lacks significant therapeutic efficacy. Regarding insomnia, there are various causes for each case; one should not abuse its use merely because of its name "Night-Closing".)
Qinpi (Fraxini Cortex)
Taste bitter, qi cold, color green, nature astringent. It primarily treats dysentery associated with Shaoyang channel heat, expels water and acts on the skin surface; clears Yang pathogens of damp-heat in the Jueyin channel, dispels wind and brightens the eyes.
(Qinpi turns green when soaked in water, does not smear when writing on paper, and repels water; thus, it enters the Liver and Gallbladder channels. Due to its cold nature, it specifically clears damp-heat from the Liver and Gallbladder. The diseases it treats are mostly caused by Liver and Gallbladder damp-heat. As for its ability to benefit Essence, this is because Essence naturally recovers once the pathogenic heat is eliminated.)
Xihe Liu (Salix Tomentella / Willow Twig)
Nature warm, taste sweet and salty. It penetrates and erupts sand-rash (scarlatiniform eruptions), possessing the power to vent the exterior and loosen the muscle layer. Its detoxification function returns to the Spleen and Stomach; bathing removes wind-induced itching, and it has effects of resolving alcohol toxicity and promoting urination.
(Xihe Liu: When rain is imminent, this willow appears to have a muggy vapor corresponding to it. Taste sweet and salty, slightly warm, entering the Spleen and Stomach channels, moving through muscles, and unblocking limbs and joints. Thus, it can erupt rashes and remove wind-itch. These effects depend on the user's interpretation of its properties.)
Yubai Pi (Ulmus Radicis Cortex)
The bark enters the Lung channel; its nature is sticky and slippery, guiding stagnation and unblocking the intestines. Elm makes people sleep (misinterpretation), taste sweet and neutral, harmonizes the Spleen and reduces water retention.
(Yubai Pi is extremely sticky and slippery, so its adhesive use surpasses actual glue or lacquer. Its nature is sweet, neutral, and non-toxic, entering the Spleen and Stomach channels, benefiting the large and small intestines, facilitating childbirth by guiding stagnation, all relying on its slippery and draining action. However, since it is a downward-draining substance, one should not consume it based on Ji Kang's statement "Elm makes people sleep." His intent was merely to suggest that the human mind should be as stable and cohesive as this sticky substance. Just as Hehuan eliminates anger and Xuancao forgets sorrow, does consuming these substances truly eliminate anger and forget sorrow? Examining the nature of Yubai Pi, it is sweet, neutral, and non-toxic, and is certainly not an attacking or purgative herb. Therefore, ancients had methods of consuming elm soup or elm flour to satisfy hunger or practice grain avoidance. However, due to its strong slippery and descending nature, it may potentially deplete body fluids.)
