（收录于《神农本草经》中品）
【释名】合昏（出自《新修本草》）、夜合（出自《日华子本草》），是一种树。
苏颂说：崔豹在《古今注》中说：“想要消除人的愤怒，就赠送青裳。青裳，就是合欢。种植在庭院台阶旁，能使人不再生气发怒。”所以嵇康在《养生论》中说：“合欢能消除愤怒，萱草能忘却忧愁。”
孟诜说：它的叶子到了傍晚就会闭合，所以叫作合昏。
李时珍说：据王璆在《百一选方》中记载：夜合俗名叫萌葛，越地人叫它乌赖，还有人叫它尸利洒树。
【集解】《神农本草经》说：合欢生长在豫州河内的山谷中。树木形状像狗骨树。
陶弘景说：世俗之人很少认识它，大概是因为它没有治疗疾病的功效吧。
甄权说：这种树的叶子像皂荚和槐树，非常细小。五月开花，花色红白相间，上面有丝状绒毛。秋天结出豆荚状的果实，种子极薄且细。各地山谷都有生长，现在东都西京的宅第山池间也有种植的，名叫合昏。
苏颂说：现在汴梁、洛阳一带都有，人们多将其种植在庭院台阶旁。树干像梧桐，枝条非常柔弱。叶子像皂角，极其细碎而繁密，互相交错连接。每当风吹来，枝叶便自然分开，互不牵连粘连。采集树皮和叶片使用，不拘泥于月份。
寇宗奭说：合欢花，颜色就像现在的晕染线，上半部分白色，下半部分肉红色，散开下垂如丝线，是花卉中的奇异品种。其绿叶到夜晚就会闭合。嫩叶时炸熟用水淘洗，也可以食用。
木皮（去除粗皮后炒制使用）
【气味】味甘，性平，无毒。
【主治】安定五脏，调和心志，使人欢乐无忧。长期服用，身体轻盈，视力明亮，能满足愿望（出自《神农本草经》）。煎制成膏，可消散痈肿，接续筋骨（出自《大明本草》）。杀虫。捣成粉末，与锅底墨混合，用生油调匀，涂抹蜘蛛咬伤造成的疮口（出自《大明本草》）。治疗跌打损伤疼痛，将花研成粉末，用酒送服二钱匕（出自寇宗奭）。
【发明】朱震亨说：合欢属土，补阴的功效非常迅速。促进肌肉生长，接续筋骨，从这一点就可以看出来了。如果与白蜡一同入药制成膏剂，效果神奇，为什么外科医生不曾录用它呢？
【附方】旧方两首，新方三首。
肺痈咳吐浊痰，心胸部位肌肤甲错：取夜合皮一大掌大小，加水三升，煮至剩下一半，分两次服用。（出自韦宙《独行方》）。
跌打损伤骨折：夜合树皮（即合欢皮，去除粗皮，炒至黑色）四两，芥菜子（炒制）一两，研成粉末。每次服用二钱，睡前用温酒送服，并将药渣敷在患处，接骨效果极佳。（出自王璆《百一选方》）。头发脱落不生：合欢木灰二合，墙衣五合，铁精一合，水萍末二合，研磨均匀，用生油调涂，每晚一次。（出自《普济方》）。小儿撮口风：用夜合花枝浓煮汁液，擦拭口腔，并清洗患处。（出自《子母秘录》）。
槐枝、桑枝、石榴枝各五两（均鲜切）。糯米五升，黑豆五升，羌活二两，防风二两，共七斤半。先用水五斗煎煮这五种树枝，取汁二斗五升，浸泡米和豆蒸熟，加入酒曲以及防风、羌活，按照通常酿酒的方法，密封发酵三七二十一天，压榨取汁。每次饮用五合，不要喝醉导致呕吐，常令体内有酒气即可。（出自《奇效良方》）
(Recorded in the Middle Category of *Shennong Bencao Jing*)
**[Names]** Hehun (as cited in *Xinxiu Bencao*), Yehe (as cited in *Rihua Zibencao*). It is a tree.
Su Song states: Cui Bao, in *Gujin Zhu*, said, "To dispel one's anger, present Qingchang. Qingchang refers to Albizia julibrissin. Planting it in the courtyard or on the steps makes people free from resentment." Thus, Ji Kang stated in *Yangsheng Lun*: "Albizia julibrissin dispels anger; Daylily (*Hemerocallis citrina*) forgets sorrow."
Meng Shen states: Its leaves close at dusk, hence the name Hehun.
Li Shizhen states: According to Wang Qiu in *Baiyi Xuanfang*: Yehe is commonly known as Mengge; people in Yue call it Wulai; others call it Shilishu.
**[Collection and Explanation]** *Shennong Bencao Jing* states: Albizia julibrissin grows in the valleys of Heyu, Yuzhou. The tree resembles *Celtis sinensis* (Dogbone tree).
Tao Hongjing states: It is rarely recognized by common people, likely because it lacks medicinal efficacy for treating diseases.
Zhen Quan states: The leaves resemble those of *Gleditsia sinensis* (Chinese Honeylocust) and *Styphnolobium japonicum* (Japanese Pagoda Tree), being extremely fine. Flowers bloom in May, appearing red and white, with silky pubescence on top. In autumn, it produces pod-like fruits with very thin and fine seeds. It grows in valleys everywhere; currently, it is also planted in the residences and gardens of the Eastern and Western Capitals, named Hehun.
Su Song states: It is now found in Bianliang and Luoyang areas, where households often plant it in courtyards. The trunk resembles *Firmiana simplex* (Chinese Parasol Tree), and the branches are very tender. The leaves resemble *Gleditsia sinensis*, being extremely fine, dense, and interwoven. Whenever the wind blows, the leaves naturally separate without clinging to each other. The bark and leaves are harvested for use, regardless of the month.
Kou Zongshi states: The flowers of Albizia julibrissin are colored like modern dyed threads, white on the upper half and flesh-red on the lower half, hanging loosely like silk, making them a unique variety among flowers. Its green leaves close at night. When tender, they can be blanched, washed with water, and eaten.
**Wood Bark** (Remove the rough outer bark and stir-fry before use)
**[Flavor and Toxicity]** Sweet, neutral, non-toxic.
**[Indications]** Calms the Five Zang organs, harmonizes the Heart spirit, and brings joy and freedom from worry. Long-term consumption lightens the body and improves vision, fulfilling desires (*Shennong Bencao Jing*). Prepared as an ointment/paste, it dissipates carbuncles and swelling, and knits bones and tendons (*Daming Bencao*). Kills parasites. Ground into powder, mixed with soot from the bottom of a cauldron, and blended with raw oil, it is applied to spider bites (*Daming Bencao*). For traumatic injuries and bone fractures causing pain, grind the flowers into powder and take two qianbi with wine (Kou Zongshi).
**[Elucidation]** Zhu Zhenheng states: Albizia julibrissin belongs to Earth and has a very rapid effect in tonifying Yin. Its ability to promote muscle growth and knit bones and tendons is evident. If used together with beeswax in an ointment, the effect is miraculous. Why have surgeons not adopted it?
**[Attached Prescriptions]** Two old prescriptions, three new ones.
For lung abscess with expectoration of turbid sputum and xerosis cutis (fish-scale skin) over the chest and heart region: Take a palm-sized piece of Yehe bark, add three sheng of water, boil until half remains, and divide into two doses (*Du Xing Fang* by Wei Zhou).
For traumatic injuries and bone fractures: Four liang of Yehe tree bark (i.e., Cortex Albiziae, remove rough bark, stir-fry until black), one liang of mustard seed (stir-fried). Grind into powder. Take two qian per dose with warm wine before bed, and apply the dregs to the affected area. This is excellent for knitting bones (*Baiyi Xuanfang* by Wang Qiu).
For hair loss and failure of regrowth: Two he of Albizia julibrissin wood ash, five he of wall moss (Qiangyi), one he of iron essence (Tiejing), two he of duckweed powder (Shuipingmo). Grind uniformly, blend with raw oil, and apply. Once every night (*Puji Fang*).
For infant lockjaw (Xiao'er Cuokou): Boil the branches and twigs of Albizia julibrissin flowers into a concentrated decoction. Wipe the mouth with it and wash the area (*Zimu Milu*).
Five liang each of *Sabina chinensis* branch, *Morus alba* branch, and *Punica granatum* branch (all fresh and chopped). Five sheng of glutinous rice, five sheng of black soybean, two liang of *Notopterygium incisum* root (Qianghuo), two liang of *Saposhnikovia divaricata* root (Fangfeng), totaling seven jin and half a liang. First, decoct the five types of branches in five dou of water to obtain two dou and five sheng of liquid. Soak the rice and beans, steam until cooked. Add yeast, along with Fangfeng and Qianghuo, following the standard method for brewing wine. Seal and ferment for twenty-one days (three sevens). Press to extract the juice. Drink five he per dose. Do not drink to excess to the point of vomiting; maintain a slight alcoholic sensation (*Qixiao Liangfang*).
