味苦、甘，气平、大寒。气薄味浓，沉也，阴也，阳中之阴。无毒。山谷俱有，夏
秋采根。蒸烂去皮去心，曝干旋咀旋用。（咀久易生霉垢，则黑黯不明亮也。）畏曾青，忌鲤
鱼。倘误食中毒，取浮萍解之。使宜贝母地黄，经人手肺足肾。疗风淫湿痹，补虚损劳伤。
杀三虫，去伏尸且强骨髓；润五脏，悦颜色尤养肌肤。解渴除烦，消痰住嗽。保肺气不被热
扰，通肾气能除热淋。止血溢妄行，润粪燥闭结。同参耆煎服，定虚喘促神方；和姜蜜熬膏
，（天门冬自然汁三碗，蜜一碗，姜汁半碗，共和匀熬膏。）破顽痰癖劫剂。单用研末调酒，
久久益气延年。肺痿肺痈，亦堪调治。盖因苦泄滞血，甘助元气，寒去肺热，此三者天门冬
之功焉。虚热人加用正宜，虚寒者切禁莫服，因专泄不能专收故尔。

味甘、微苦，气平，微寒。降也，阳中微阴。无毒。阔 平堤，土肥则产。叶类莎
草长秀，根如麦颗连珠，故因名麦门冬也。畏苦参、青 、木耳，恶苦 、苦瓠、款冬。去
心用不令人烦，择肥大方获效速。地黄车前为使，入手太阴少阴。治肺伏火邪，及肺痿脓吐
腥臭；补心劳伤损，并心血错经妄行。益精强阴，驱烦解渴。心腹结气能散，肠胃伤饱可消
。美颜色，悦肌肤，止呕吐，愈痿蹙。（音促。）去心下支满，退虚热客邪。经枯乳汁不行，
堪资作引；肺燥咳声连发，须使为君。加五味、人参三者同煎，名生脉散。子专补元气，与
地黄、阿胶、麻仁共用，能润经益血，复脉通心。按∶《本经》多治脾胃脏腑，后用者专疗
心肺两经。久服轻身，不饥不老。
（谟）按∶天、麦门冬并入手太阴经，而能驱烦解渴，止咳消痰。功用似同，实亦有偏
胜也。
麦门冬兼行手少阴心，每每清心降火，使肺不犯于贼邪，故止咳立效；天门冬复走足少阴肾
，屡屡滋肾助元，令肺得全其母气，故消痰殊功。盖痰系津液凝成，肾司津液者也，燥盛则
凝，润多则化。天门冬润剂，且复走肾经。津液纵凝，亦能化解。麦门冬虽药剂滋润则一，
奈经络兼行相殊。故上而止咳，不胜于麦门冬；下而消痰，必让于天门冬尔。先哲亦曰∶痰
之标在脾，痰之本在肾。又曰∶半夏惟能治痰之标，不能治痰之本。以是观之，则天门冬
惟能治痰之本，不能治痰之标。匪但与麦门冬殊，亦与半夏异也。

Bitter, sweet, neutral in nature, extremely cold. Thin qi and strong flavor, sinking, yin, yin within yang. Non-toxic. Grows in valleys, roots harvested in summer and autumn. (Steamed until soft, peeled, core removed, dried in sun, then chopped for immediate use. (If left chopped for too long, mold may grow, turning it dark and dull.) ) Feared by Zengqing, avoid carp. If poisoned by accidental ingestion, use Spirodela (Floating Duckweed) to detoxify. Compatible with Fubei (Fritillaria Bulb) and Dihuang (Rehmannia Root), enters Hand Taiyin Lung Meridian and Foot Shaoyin Kidney Meridian. Treats wind-damp bi syndrome, tonifies deficiency and damage from overwork. Kills three parasites, removes latent corpses, strengthens bone marrow; moistens five zang organs, beautifies complexion, nourishes skin. Relieves thirst, eliminates irritability, resolves phlegm, stops cough. Protects lung qi from heat disturbance, unblocks kidney qi to eliminate hot strangury. Stops bleeding due to reckless flow, moistens intestines to relieve dry constipation. Decocted with Renshen (Ginseng Root) and Qishi (Astragalus Root), it is a divine formula for stabilizing deficiency asthma; boiled with ginger and honey into paste, (Three bowls of natural juice of Tianmendong, one bowl of honey, half bowl of ginger juice, mixed evenly and boiled into paste.) it is a drastic agent for breaking stubborn phlegm and masses. Taken alone as powder mixed with wine, taken over time, it benefits qi and prolongs life. Also suitable for treating lung abscess and lung萎 (lung atrophy). This is because bitterness drains stagnant blood, sweetness supports original qi, and cold clears lung heat; these three are the merits of Tianmendong. Suitable for those with deficiency-heat, strictly contraindicated for those with deficiency-cold, because it only drains and does not consolidate.

Sweet, slightly bitter, neutral in nature, slightly cold. Descending, slight yin within yang. Non-toxic. Grows on wide, flat embankments where soil is fertile. Leaves resemble sedge, long and elegant; roots like wheat grains linked in pearls, hence named Maidong (Wheat's Door Winter). Feared by Kushen (Sophora Root), Qingmu (Cinnabar?), and wood ear mushroom; detested by Kuxin (Stemona Root), Kuhu (Bitter Melon), and Kuandonghua (Adenophora Flower). Removing the core prevents irritability; selecting plump roots ensures rapid efficacy. Compatible with Dihuang (Rehmannia Root) and Cheqiancao (Plantago Seed/Herb), enters Hand Taiyin and Hand Shaoyin meridians. Treats latent fire pathogen in lungs, and lung abscess with purulent, foul-smelling sputum; tonifies heart deficiency and damage, and regulates erratic heart blood flow. Benefits essence, strengthens yin, dispels irritability, relieves thirst. Dissolves qi stagnation in chest and abdomen, resolves fullness from overeating. Beautifies complexion, nourishes skin, stops vomiting, cures weakness and shortness of breath. (Pronounced cu.) Removes subcostal fullness, dissipates deficiency heat and external pathogens. When meridions are dry and lactation fails, it serves as a guiding drug; when lung dryness causes continuous coughing, it should be used as the sovereign drug. Decocted together with Wuweizi (Schisandra Fruit) and Renshen (Ginseng Root), it is called Shengmai San (Generate Pulse Powder). The seeds specifically tonify original qi; when used together with Dihuang (Rehmannia Root), Ejiao (Donkey-hide Gelatin), and Humaoren (Hemp Seed), they moisten meridians, benefit blood, restore pulse, and unblock the heart. Note: Benjing primarily treats spleen and stomach organs, while later practitioners focus on lung and heart meridians. Long-term use lightens the body, prevents hunger, and delays aging.
(Mo) Note: Both Tianmendong and Maidong enter Hand Taiyin meridian, dispel irritability, relieve thirst, stop cough, and resolve phlegm. Their functions seem similar, but actually have different emphases.
Maidong also traverses Hand Shaoyin Heart meridian, often clearing heart fire and descending flames, preventing the lung from being attacked by evil pathogens, thus stopping cough immediately; Tianmendong also traverses Foot Shaoyin Kidney meridian, frequently nourishing kidney and assisting yuan qi, allowing the lung to receive its mother qi, thus resolving phlegm remarkably. Phlegm is formed by congealed fluids, and the kidney governs fluids; when dryness prevails, fluids congeal; when moisture abounds, fluids transform. Tianmendong is a moistening agent that also traverses the kidney meridian. Even if fluids congeal, it can resolve them. Although both Maidong and Tianmendong are moistening agents, their meridian pathways differ. Therefore, for upper cough, it cannot surpass Maidong; for lower phlegm resolution, it must yield to Tianmendong. Ancient sages also said: The branch of phlegm lies in the spleen, the root of phlegm lies in the kidney. Also said: Banxia (Pinellia Tuber) can only treat the branch of phlegm, not the root. From this perspective, Tianmendong can only treat the root of phlegm, not the branch. Not only is it different from Maidong, but also distinct from Banxia.
