味甘，微寒，无毒。入心、肺二经。地黄、车前为使。
恶款冬花。忌鲫鱼。肥白者佳，去心用。
退肺中伏火，止渴益精，清心气惊烦，定血疗咳。燥咳痰稠宜用，咽干津少频尝。
麦门冬，禀秋金之微寒，得西方之正色，故清肺多功。心火焦烦，正如盛暑，秋气一至，

蒸若失矣。心主血，心既清宁，妄行者息。脾受湿热、则肌肉肿而肠胃满，热去即湿除，肿
满者自愈。金不燥，则不渴。金水生，则益精。
麦门冬与天门冬，功用相当，寒性稍减，虚寒泄泻，仍宜忌之。

能清除肺中潜伏之火，止渴并补益精气，清心安神以除惊悸烦闷，止血并治疗咳嗽。适用于燥咳且痰液粘稠者，咽干津液不足者可频繁服用。
麦门冬（Ophiopogonis Radix），禀受秋季金气的微寒之性，得西方正色，因此具有多重清肺功效。若心火炽盛导致焦躁烦闷，正如盛夏酷暑，一旦秋气到来，炎热蒸腾之感便消失殆尽。心主血脉，心火既清则心神安宁，血液妄行自止。脾脏受湿热困扰，则肌肉肿胀而肠胃胀满；热邪去除则湿气随之消除，肿胀胀满自然痊愈。肺金不燥，则无口渴之症。肺金与肾水相生，则能补益精气。
麦门冬与天门冬（Asparagi Radix）功效相当，但麦门冬的寒性稍弱，对于虚寒导致的泄泻，仍应禁忌使用。
又名臭橘、臭枳，味辛、苦，性温。
其气味能引导毒邪外出，其宣散之性能解除郁结。治疗咽喉怪症（喉痹生疮），治疗里急后重及下痢脓血。
夏子益在《奇病方》中说：“咽喉生疮，层层重叠如叠状。不疼痛，日久散发臭气，无法进食饮水，用臭橘叶煎汤，连续服用必定痊愈。”李时珍认为此叶“治疗喉痹肿痛，消肿导毒”。其果实也能治疗喉蛾（扁桃体炎）。
味甘、微酸，性平，无毒。归心、脾、胃、肾四经。
消除咽喉肿胀，通利关节。对于喉舌肿胀闭塞、水浆难入的情况，可消除流注（深部脓肿或结节），并能坚固筋骨。
此药以开芳香小白花的品种为佳，适用于喉蛾与关节肿痛同时发作的情况。
味苦，性平，无毒。归心包经和肝经。
活血行气以止痛，消肿散结以解毒。痈疽尚未化脓、脓液未成熟时，迅速破除瘀血，在病灶未稳固前先驱逐邪气。喉痈初起时，用它煎服，往往能使肿块消散，避免病情危重。外敷于疮疡肿毒处，能约束病势。
此药宜早用，能在气血刚刚凝结之际消除痈肿。其外消之力也很大。如意金黄散中就使用了此药。

When Metal (Lung) is not dry, there is no thirst. When Metal generates Water (Kidney), Essence is benefited.
