【主治】主妇人乳产 痛，七伤，带下，五漏，止痛，止汗，除恶肉，疗金疮。
【核】曰∶生平原川泽。三月宿根布地作苗，独茎直上，高三、四尺，对分出青色叶，
似榆叶稍狭，细而长，边有锯齿。七月开花如椹，根似柳，外黑内红。根可酿酒，道方以之
烧灰煮石。得发良。恶麦门冬，伏丹砂、雄、硫。
【 】曰∶地，坤道也，至柔而动也刚，煮石成糜，足征刚而动矣。榆从俞，俞者，空
中木，若舟楫之利，以济不通，故主脉道壅塞，致营血不能分流经隧，而为带下，五漏，乳

【核】曰∶生豫州山谷，及益州、汴洛，所在山谷亦有。植之庭除，令人不忿。嵇康《养
生论》云∶合欢蠲忿，萱草忘忧。古今注云∶欲蠲人忿，赠以青裳。青裳，合欢也，越人谓
之乌赖树，金光明经谓之尸利洒树，俗谓之萌葛树也。干似梧桐，枝甚柔弱。叶如皂角，细
而繁密，互相交结，每一风来，辄自相解，了不相牵。五月发花红白，上有丝茸。秋实作荚，
子极纤薄。收采皮叶，不拘时月。修治其皮，削去粗皮，缓火焙炒。
先人云∶阳动而开，阴静而合，此至和，此至安也。动而能静，开而必合，此方至和，
此方至安也。若动不能开，静不能合，与动不能静，开不能合，斯不和，斯不安矣。合欢昼
而阳舒，夜而阴合，静时交结，动不相牵，开合动静，咸得所欲，是得阴阳之正，既安且和，
人
【 】曰∶昼开夜合，以昼夜为呼吸者也。当安心肺之阳，肾肝之阴，并安中州，滋培
后天者欤。和心志欢乐无忧者，以脏安则神安，神安则志溢，志溢则无恐惧忧悲矣。俨似卫
气之出入，亦可安卫气之昼出于阳，夜入于阴。更安营气之周行经隧，镇定中州故也。息同
天地，故久服轻身明目，皆得所欲。
（呼出心与肺，吸入肾与肝。呼吸之间，脾受谷味，其脉在中。脾者，中州也。）
（惟脏安心和，故欢乐无忧。惟欢乐无忧，久之自身轻目明，而欲得矣。盖气郁闷则重
滞，乐则飞扬而轻也。肝屈抑则目昏，乐则开爽而明也。心愁虑，则不能如意，乐则从心所
欲，无弗得也。）

【气味】味辛、苦，性微寒，无毒。
【主治】主治妇女产后乳房疼痛，七伤，带下病，五漏，止痛，止汗，去除恶肉，治疗金疮（金属利器造成的创伤）。
【核】曰：地榆生长在平原川泽之地。三月时宿根在地面萌发新苗，独茎直立向上，高三四尺，对生分出青色叶片，形状像榆叶但稍狭，细长且边缘有锯齿。七月开花如桑葚，根部像柳树，外皮黑色内里红色。根可用来酿酒，道家方术用它烧成灰来煮石。与头发同用效果良好。忌麦门冬，畏丹砂、雄黄、硫磺。
【 】曰：地，代表坤道，极其柔顺但运动时却刚强，煮石成粥，足以证明其刚健而动的特性。榆字从俞，俞意为空中之木，如同舟楫之利，用以疏通不通之处，所以主治脉道壅塞，导致营血不能分流至经络隧道，从而产生带下、五漏、乳产疼痛、出汗等各种证候，就像借助木材（舟楫）的功效一样。
（不仅可作为舟楫，也可作为车乘，都是借助木材的功效。）

【气味】味甘，性平，无毒。
【主治】主治安养五脏，调和心志，使人欢乐无忧。长期服用可使身体轻健，明目，满足各种愿望。
【核】曰：合欢生长于豫州的山谷，以及益州、汴洛等地，所在山谷也有种植。种在庭院台阶旁，能让人不生忿怒。嵇康《养生论》说：“合欢消除忿怒，萱草忘记忧愁。”古今注说：“想要消除人的忿怒，赠送青裳。青裳就是合欢，越人称之为乌赖树，《金光明经》称之为尸利洒树，俗称为萌葛树。”树干像梧桐，枝条非常柔弱。叶子像皂角，细密繁茂，互相交结，每当风吹来时，枝叶便自行解开，互不牵连。五月开红白花，上面有丝状绒毛。秋天结果实为荚，种子极纤细薄。采收皮叶不拘时节。炮制其皮，削去粗皮，用慢火焙炒。
先人说：阳动而开，阴静而合，这是至极的和，至极的安。动而能静，开而必合，这才是真正的和，真正的安。如果动不能开，静不能合，或者动不能静，开不能合，这就是不和，不安了。合欢白天阳气舒展，夜晚阴气闭合，静止时枝叶交结，运动时互不牵连，开合动静，都能满足其需求，这是得到了阴阳的正道，既安宁又和谐，人……
【 】曰：白天开放晚上闭合，是以昼夜作为呼吸。应当安心肺之阳，肾肝之阴，并安养中州，滋培后天之本吧。使心志调和、欢乐无忧，是因为脏腑安宁则神志安宁，神志安宁则意志充盈，意志充盈就没有恐惧忧悲了。俨然像卫气的出入，也可以安定卫气昼出于阳、夜入于阴的规律。更安养营气在经络隧道中的周行，镇定中州的原因。气息同于天地，所以长期服用身体轻健、明目，都能得到所愿。
（呼出之气由心与肺主管，吸入之气由肾与肝主管。呼吸之间，脾受纳谷味，其脉在中。脾，是中州。）
（只有脏腑安宁、心和，所以欢乐无忧。只有欢乐无忧，久而久之自身轻健目明，欲望就能得到满足。因为气郁闷则重滞，快乐则飞扬而轻。肝气屈抑则目昏，快乐则开爽而明。心里愁虑，则不能如意，快乐则随心所欲，无不得到满足。）
(Shanghan Lun, Middle Category)
[Flavor and Nature] Pungent, bitter, slightly cold, non-toxic.
[Indications] Primarily treats breast pain in women after childbirth, seven injuries, leukorrhea, five types of leakage, stops pain, stops sweating, removes foul flesh, and treats metal wounds (traumas caused by metal weapons).
[Analysis] It is stated: Grows in plains and river marshes. In the third month, perennial roots sprout seedlings on the ground; a single stem grows straight upward, three to four chi high, with opposite pairs of green leaves that resemble elm leaves but are slightly narrower, slender and long, with serrated edges. Flowers bloom in the seventh month resembling mulberries; the root resembles willow, black on the outside and red inside. The root can be used to brew wine; Daoist formulas use it calcined to ash for boiling stones. It works well when combined with hair. It is incompatible with Ophiopogonis Radix (Maidong), and its effects are inhibited by Cinnabaris (Zhusha), Realgar (Xionghuang), and Sulfur (Liuhuang).
[Commentary] Earth represents the Kun principle; it is extremely soft yet moves with strength. Boiling stones into porridge demonstrates its hardness and movement. 'Yu' (elm) derives from 'Yu' (to convey/pass through), meaning wood hollowed out like a boat or raft, facilitating passage where there is blockage. Thus, it primarily treats obstruction of the vessel pathways, causing Ying blood unable to flow into the meridians and collaterals, resulting in conditions such as leukorrhea, five leakages, postpartum breast pain, and sweating, much like the utility of wooden boats.
(It serves not only as a boat but also as a carriage, both utilizing the utility of wood.)
(Shanghan Lun, Middle Category)
[Flavor and Nature] Sweet, neutral, non-toxic.
[Indications] Primarily nourishes and calms the five Zang organs, harmonizes the mind and spirit, making one joyful and free from worry. Long-term consumption lightens the body, brightens the eyes, and fulfills desires.
[Analysis] It is stated: Albizia julibrissin grows in the valleys of Yuzhou, as well as in Yizhou, Bian, and Luo regions, and is found in valleys wherever planted. Planting it in courtyards prevents resentment. Ji Kang's "Discourse on Nourishing Life" states: "Albizia eliminates resentment, daylily forgets sorrow." Ancient and Modern Notes state: "To eliminate resentment, gift Qing Shang. Qing Shang is Albizia; Yue people call it Wulai Tree; the Golden Light Sutra calls it Shili Sa Tree; commonly known as Mengge Tree." The trunk resembles Paulownia, branches very tender. Leaves resemble Sophora, fine and dense, interlocking; when wind blows, they separate naturally without tangling. Red and white flowers bloom in May, covered with silky fuzz. Pods form in autumn, seeds extremely thin and flat. Bark and leaves can be harvested at any time. For processing, scrape off the rough bark and slow-roast.
Ancestors said: Yang moves and opens; Yin is still and closes. This is ultimate harmony and peace. Movement leads to stillness; opening leads to closing. This is true harmony and peace. If movement cannot open, stillness cannot close, or movement cannot lead to stillness, opening cannot lead to closing, this is disharmony and unrest. Albizia expands Yang during the day and closes Yin at night; leaves interlock when still and do not tangle when moving. Opening, closing, movement, and stillness all fulfill their nature, achieving the correct balance of Yin and Yang, bringing both peace and harmony to humans...
[Commentary] Opening by day and closing by night uses day and night as respiration. It should calm the Yang of Heart and Lung, the Yin of Kidney and Liver, and soothe the Central Region, nourishing the Post-Heaven foundation. Harmonizing the mind to bring joy and freedom from worry occurs because when Zang organs are calm, Shen (Spirit) is calm; when Shen is calm, Yi (Will) overflows; when Yi overflows, there is no fear or sorrow. It resembles the circulation of Wei Qi, stabilizing Wei Qi's exit to Yang during the day and entry to Yin at night. It further calms the circulation of Ying Qi through the meridians and stabilizes the Central Region. Respiration aligns with Heaven and Earth; thus, long-term consumption lightens the body, brightens the eyes, and fulfills desires.
(Exhalation is governed by Heart and Lung; inhalation by Kidney and Liver. Between breaths, Spleen receives grain essence, its pulse located centrally. Spleen is the Central Region.)
(Only when Zang organs are calm and Heart is harmonious is there joy and freedom from worry. Only with joy and freedom from worry does the body become light and eyes clear over time, fulfilling desires. Depressed Qi causes heaviness; joy makes it light and soaring. Suppressed Liver Qi causes dim vision; joy clears and brightens it. Worried Heart cannot achieve wishes; joy allows following one's heart's desire, achieving everything.)
