居瘴地者，虽曰节慎起居，而防病之药不可不为之备，如人参、附子、干姜、当归、熟
地、紫金锭、苏合丸、不换金正气散之类，皆不可须臾离也。从宦兹土，则政事多繁，上下
交际，为商往来，则经营贸易，其势不容于自逸，稍觉不快，即宜如法服药以解之。微邪易
伏，固不致病也，惟其不能防微，则势必至于渐盛。故曰∶不治已病治未病，此之谓也。
两关脉洪大者，热瘴。脉数甚者，为热瘴。脉弦而紧者，为瘴疟。脉浮而紧者，宜解表
。脉浮缓者为伤风，其病轻。脉洪数而按之不实者，为阳浮阴闭。脉沉微而弱者，为虚寒。
凡瘴病，不发三日后，方可洗手。七日后可洗面。半月后可梳头。一两月后，谨戒房事
，能戒百日，尤好。又瘴不发后，须吃素粥三日，经五日后，方可以猪脾煮羹，吃软饭。十
日后略可吃酒，少用肉羹。但不可食诸般骨汁。若犯之则再发，凡牛羊猪犬鸡鹅诸骨汁，须
并忌一月，或两月犹佳。凡犯而再发，必多困笃。

居住在瘴气之地的人，虽然说要谨慎地调节起居生活，但预防疾病的药物不可不提前准备，比如人参、附子、干姜、当归、熟地黄、紫金锭、苏合丸、不换金正气散这类药物，都是片刻不能离开的。如果在当地做官，政务通常繁忙；与商人往来经商，需要经营贸易，这种形势不允许自己安逸，稍微感到身体不适，就应当依法服用药物来解除病邪。轻微的邪气容易潜伏，本来不会致病，但如果不能防微杜渐，病情势必会逐渐加重。所以说：“不治已经发生的疾病，而治尚未发生的疾病”，说的就是这个道理。
两手关部脉象洪大的，是热瘴。脉象数急严重的，也是热瘴。脉象弦而紧的，是瘴疟。脉象浮而紧的，适宜用解表法治疗。脉象浮而缓的是伤风，病情较轻。脉象洪大且数，但重按不实的是阳浮阴闭。脉象沉微而弱的是虚寒证。
凡是患瘴病，在症状未发作三天后，才可以洗手。七天后可以洗脸。半个月后可以梳头。一到两个月后，要谨慎戒除房事，如果能戒除一百天，尤其好。另外，瘴病症状停止发作后，必须吃素粥三天，经过五天后，才可以用猪脾煮羹汤，吃软饭。十日后可以稍微喝点酒，少量食用肉羹。但是不能吃各种骨头熬制的汁液。如果违反禁忌导致复发，凡牛羊猪狗鸡鹅等各种骨头汁，都必须忌口一个月，或者两个月更好。凡是触犯禁忌再次复发的，病情一定会更加困顿危重。

Those residing in miasma-prone areas, although advised to be cautious with their daily routines, must not fail to prepare preventive medicines. Such as *Renshen* (Ginseng Radix), *Fuzi* (Aconiti Lateralis Radix Praeparata), *Ganjiang* (Zingiberis Rhizoma), *Danggui* (Angelicae Sinensis Radix), *Shudi* (Rehmanniae Radix Preparata), *Zijin Ding* (Purple Gold Ingot), *Suhe Wan* (Styrax Pill), and *Buhuanjin Zhengqi San* (Non-Exchanging Metal Qi-Regulating Powder), among others, are indispensable at all times. For those serving as officials in this region, administrative duties are often heavy; for merchants traveling there for trade, business operations do not allow for leisure. If one feels slightly unwell, one should immediately take medicine according to proper methods to resolve the pathogen. Mild pathogens are easily suppressed and may not cause disease; however, if one fails to prevent them from developing, the condition will inevitably worsen gradually. Thus it is said: "Treat the disease before it arises," which refers to this principle.
If the pulse at both Guan positions (middle position on the radial artery) is surging and large, it indicates Heat Miasma. If the pulse is rapid and severe, it also indicates Heat Miasma. If the pulse is wiry and tight, it indicates Miasma Malaria. If the pulse is floating and tight, exterior-resolving treatment is appropriate. If the pulse is floating and moderate, it indicates Wind Injury, which is a mild condition. If the pulse is surging, rapid, but empty upon deep pressure, it indicates Yang Floating and Yin Obstruction. If the pulse is deep, minute, and weak, it indicates Deficiency-Cold.
For any miasma illness, after symptoms have not manifested for three days, one may wash hands. After seven days, one may wash the face. After half a month, one may comb hair. After one to two months, sexual activity must be strictly abstained from; abstinence for one hundred days is particularly beneficial. Furthermore, after the cessation of miasma symptoms, one must consume vegetarian porridge for three days. After five days, one may eat soft rice with soup made from pig spleen. After ten days, one may drink a little wine and consume small amounts of meat broth. However, one must avoid consuming juices extracted from various bones. Violating this will cause recurrence. Juices from cattle, sheep, pigs, dogs, chickens, and geese bones must be avoided for one month, or preferably two months. Any recurrence due to violation will likely result in a more critical and debilitating condition.
