瘴气，惟东南之域乃有之。盖岭南地气卑湿，雾多风少，且以冬时常暖，则阴中之阳气
不固，夏时反凉，则阳中之阴邪易伤，故人有不知保重而纵欲多劳者，极易犯之，以致发热
头痛，呕吐腹胀等证。盖重者即伤寒，轻者即疟疾，第在岭南病此，则均谓之瘴耳。然阳气
外浮之乡，必内多真寒而外多假热；阴气不固之人，虽外有邪证而内必多虚，此则岭南瘴疫
之大概也。但予未经其地，此不过亿度之见耳。及阅诸家之论，最多得理，足征予言之不诬
也，谨详录在下，以资择用，庶临证者可无惑，而病此者得所赖矣。又细察诸论，亦已详悉
，第病其用补之法犹有未尽，若值内伤虚损之甚而病此将危或难愈者，必以前瘟疫门治法参
而用之，则庶乎有济。

瘴气，只有在东南地区才有。大概岭南地区地势低洼潮湿，雾气多而风少，并且冬天时常温暖，导致阴中之阳气不固；夏天反而凉爽，导致阳中之阴邪易伤人体。所以有人不知道保重身体而纵欲过度、劳累过多，极易感染此病，以致出现发热、头痛、呕吐、腹胀等症状。大概病情重的就是伤寒，轻的就是疟疾，只是在岭南地区患这些病，都称之为瘴气罢了。然而，在阳气外浮的地方，体内必然多有真寒而体表多有假热；阴气不固的人，虽然外表有邪气症状，但体内必然多虚，这就是岭南瘴疫的大致情况。但我未曾亲自去过那里，这不过是推测之见罢了。等到阅读各家论述，发现大多合乎情理，足以证明我的话没有虚假，谨详细记录在下文，以供选择使用，希望临证时医生可以没有疑惑，而患病者能得到依靠。又仔细考察各家论述，也已经非常详尽，只是担心他们使用的补益方法还有未尽之处，如果遇到内伤虚损严重且患此病即将危重或难以痊愈的情况，必须参考前文瘟疫门的治法结合使用，这样或许会有帮助。

Zhang qi (miasma) is found only in the southeastern regions. Generally, the Lingnan region has low-lying and damp terrain, with much fog and little wind. Moreover, it is often warm in winter, causing the yang qi within yin to be insecure; conversely, it is cool in summer, making the yin evil within yang prone to injuring the body. Therefore, those who do not take care of themselves and indulge in desires or excessive labor are extremely susceptible to contracting this disease, resulting in symptoms such as fever, headache, vomiting, and abdominal distension. Generally, severe cases constitute Shanghan (Cold Damage), while mild cases constitute Malaria. However, when these diseases occur in Lingnan, they are all referred to as Zhang. In regions where yang qi floats outward, there must be true cold internally and false heat externally; in individuals with insecure yin qi, although there are external pathogenic signs, there must be deficiency internally. This is the general situation regarding zhang epidemics in Lingnan. However, I have not personally visited that place, so this is merely an educated guess. Upon reviewing the discussions by various authors, I find them mostly reasonable, which confirms that my words are not false. I have carefully recorded them below for reference, hoping that clinicians will have no confusion and patients will have support. Furthermore, upon careful examination of these discussions, they are already quite detailed. However, I am concerned that their use of tonification methods is not exhaustive. If one encounters a case of severe internal injury and deficiency complicated by this disease, which is critical or difficult to cure, one must refer to and combine the treatment methods from the preceding Plague section. Only then might there be hope for benefit.
