医经中说：因受暑邪而汗出，心烦时会出现喘促和大声呼喊（大声也）。又说：阳气虚则体表寒冷，阴气虚则体内发热。这种证候多属于阴虚，由于肾水亏虚、心火亢盛，所以心烦（心神不安）必然伴有躁动（身体不安），在夏季暑热时节多见；此外，在呕吐腹泻之后出现心烦且口渴的情况也很常见。伤寒病后以及妇女产后，若出现心烦口渴、手足冰冷、脉象沉细者，这是内伤元气，邪气潜伏于至阴之脏，随体质转化所致。此时六脉沉迟，津液枯竭、舌面干燥，适宜使用干姜、附子类的方剂，以回复阴液、回阳救逆。如果营卫失调，导致亢奋烦躁再次发作，或者症状相似但脉象沉数有力，伴有口渴、大便秘结，这属实热证，适宜用承气汤攻下。若有表里俱实的实热烦渴，用人参白虎汤。若有伤寒后极度口渴，饮水即吐，烦躁欲死，用竹叶石膏汤（均见于《伤寒论》），去掉人参，加入知母。对于心烦口渴，可用辰砂六一散或灯心草汤服用；对于烦热、口渴，用五苓散（方剂见小便不通章节）；对于神志恍惚，用妙香散（方剂见癫痫章节）；对于失眠，用清心莲子饮（见淋证章节）。脉象大而缓者为吉兆，急数者为凶兆。

As stated in the medical classics: "Due to summerheat, sweating occurs; when vexation arises, there is panting and loud shouting (loud voice)." It also states: "Yang deficiency leads to external cold, Yin deficiency leads to internal heat." This syndrome mostly belongs to Yin deficiency, where water (Kidney Yin) is depleted and fire (Heart Fire) is flourishing. Consequently, vexation (mental uneasiness) must be accompanied by restlessness (physical agitation), which is common during the summer months. It also frequently occurs after vomiting and diarrhea, presenting with vexation and thirst. After contracting Cold Damage (Shanghan) or following childbirth in women, if vexation, thirst, cold extremities, and a deep pulse are present, this indicates injury to the primordial Qi, with pathogenic factors latent in the extreme Yin organs, transforming according to the constitution. With six pulses being deep and slow, dry fluids, and a dry tongue, it is appropriate to use formulas containing dried ginger (Ganjiang) and prepared aconite (Fuzi) to restore Yin and return Yang. If the disturbance of Ying and Wei mechanisms causes hyperactive vexation to recur, or if symptoms appear similar but the pulse is deep, rapid, and forceful, accompanied by thirst and constipation, this constitutes excess-heat, and Chengqi Decoction should be used to purge. For exterior and interior excess-heat with vexation and thirst, Renshen Baihu Tang (Ginseng White Tiger Decoction) is indicated. For severe thirst after Cold Damage, where drinking water induces vomiting, and extreme restlessness, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is used (both seen in Shanghan Lun); remove Ginseng and add Anemarrhena (Zhimu). For vexation and thirst, Chen Sha Liuyi San (Cinnabar Six-One Powder) or Dengxin Cao Tang (Juncus Decoction) may be taken; for vexatious heat and thirst, Wuling San (Five-Ingredient Powder with Poria) is used (formula see section on Dysuria); for mental confusion, Miaoxiang San (Wonderful Fragrance Powder) is used (formula see section on Epilepsy); for insomnia, Qingxin Lianzi Yin (Clear Heart Lotus Seed Decoction) is used (see section on Strangury). A large and slow pulse is auspicious; a rapid and tense pulse is ominous.
