轻者作两三次出，大小不等，头面稀少，胸前、眼中皆无，根窠红活，肥满光泽，形似水珠，不渴泻，不烦躁。
重者一齐出，密如蚕种，顶陷如茱萸样，或平头灰白色，渴泻烦躁，头温足冷，身热不除。治之如法，十全八九。
轻变重所犯者七∶不忌口味，不慎饮食，致伤脾胃。先曾泄泻里虚，毒瓦斯不能发出。冒风寒，所谓春夏之气为
顺，秋冬之气为逆，大忌感冒风寒损表。犯房室。饵凉药，宜用滋补血气壮脾之药，不宜清凉宣利之剂，里寒则毒
气不能攻出。秽气相触血气，闻香则顺，闻臭则逆，顺则易出易靥，逆则难愈。生人辄至，恐外人由生产房室，或
临丧而来，或带醉、或食腥气，因此秽恶之触，皆为害也。
重变轻所慎者五∶谨避风寒，及房内有风亦宜避之，惟夏不忌，如遇狂风辄寒，亦宜避之。常和暖，寒则添衣，
热则减去，务得中和，毋令太过不及。节饮食，忌柿、橘、西瓜、菱角、水蜜等冷物，恐内伤胃气；尤忌肥肉油
腻，恐泄泻；忌咸物，恐作渴；忌酒、葱、蒜、鱼、羊等腥物恐致疮痒。务使脾胃充实，其疮易出易靥也。大便稠，饮
食调和，不致泄泻。一日二日一次为调，日行二三次为利，三四日不行为秘。根据方调理，避风寒，节饮食，详证用药，
庶不致轻变为重矣。
Mild cases manifest as eruptions occurring in two or three batches, varying in size, sparse on the head and face, absent from the chest and eyes, with roots that are red, vibrant, plump, and glossy, resembling water droplets; accompanied by no thirst, no diarrhea, and no restlessness.
Severe cases manifest as simultaneous eruption, dense as silkworm eggs, with depressed apices resembling cornels (Cornus officinalis), or flat-topped and grayish-white; accompanied by thirst, diarrhea, restlessness, warmth of the head but coldness of the feet, and persistent body heat. If treated according to proper methods, eight or nine out of ten cases will be cured.
The seven errors causing a transition from mild to severe are: failing to observe dietary restrictions and being careless with food intake, thereby injuring the Spleen and Stomach; previous diarrhea leading to interior deficiency, preventing the pathogenic toxins from being expelled; exposure to wind and cold—whereas the Qi of spring and summer is favorable and that of autumn and winter is unfavorable, it is strictly taboo to catch a cold and damage the exterior; engaging in sexual intercourse; administering cooling medicines instead of those that tonify Blood and Qi and strengthen the Spleen; using cooling and purgative agents leads to interior cold, preventing toxic Qi from being attacked and expelled; contact with foul odors affects Blood and Qi—pleasant scents promote smooth progression, while foul odors hinder it; smooth progression facilitates eruption and crusting, while hindrance makes recovery difficult; allowing strangers to enter, fearing that outsiders coming from childbirth chambers or funeral sites, or those who are drunk or have consumed fishy/foul foods, bring harmful foul influences through contact.
The five precautions for transitioning from severe to mild are: carefully avoiding wind and cold; even drafts within the room should be avoided, except in summer, but if strong winds cause chilliness, avoidance is necessary; maintaining consistent warmth—adding clothes when cold, removing them when hot, striving for balance without excess or deficiency; regulating diet—avoiding cold items such as persimmons, oranges, watermelons, water caltrops, and honeyed sweets to prevent internal injury to Stomach Qi; especially avoiding fatty meats and greasy foods to prevent diarrhea; avoiding salty foods to prevent thirst; avoiding fishy substances such as alcohol, green onions, garlic, fish, and mutton to prevent pruritus of sores. It is essential to ensure the sufficiency of the Spleen and Stomach, so that sores erupt and crust easily. Thick stools indicate harmonious diet and no diarrhea. Once daily is considered regulated; two to three times daily is considered unobstructed; once every three to four days is considered constipation. By following the prescription, avoiding wind and cold, regulating diet, and prescribing medication based on detailed syndrome differentiation, one can hopefully prevent mild cases from becoming severe.
