身无大热。痘脚稀疏。根窠红绽。不泻不渴。乳食不减。四肢温和。声音清亮。精神如
常。脉
象和缓。此属顺症。不须服药自愈。至若逆症。咳嗽声哑。饮食挫喉。一恶也。腹胀气促。
闷乱不宁。二恶也。渴泻不止。切牙寒战。三恶也。疮嫩易破。痒 不止。四恶
也。紫黑灰色。顶陷喘渴。五恶也。若按上法急为救疗。十中尚可全活八九。慎勿以其恶。
遂
弃而不治也。此外尚有轻变为重。所犯者七。一不忌口味生冷滑腻。致令脾胃受伤。二先曾
泄
泻。里虚不能托毒外出。三过服表药。或不避风寒。致损表气。四饵凉药。及妄用攻里之剂
。致令里气虚寒。毒瓦斯不能发出。五秽气所触。详见种痘说内。盖血气闻香则顺闻臭则逆。
顺
则易出易靥。逆则难愈。六生人辄至。及僧尼孝服。七犯房屋。又重变为轻。返凶为吉。所
慎者五。一谨避风寒。二身常和暖。寒则添衣。热则减去。务得中和。毋令太过不及。三节
饮食。大忌西瓜柿橘菱角水蜜等冷物。恐内伤胃气。及肥肉油腻。滑肠作泻。酸咸作渴。
酒
葱蒜鱼羊腥物作痒。务使脾胃充实。则痘疮易出易靥也。四大便稠。饮食调和。不致泄泻。
一日二日一次为调。日行二三次为利。宜急用甘温补脾药。若值灌浆之时。虽三四日不行。
不得误以为秘。五按法调理。补气血。顾脾胃。避风寒。节饮食。毋妄汗。毋妄下。斯皆可
以转重就轻。返逆为顺。庶几不致变轻为重矣。
身体没有明显的高热。痘疹的根部稀疏，痘基红润绽开，没有腹泻也没有口渴感，吃奶和进食量没有减少，四肢温暖，声音清脆响亮，精神状况如常，脉象平和缓畅。这属于顺症（病情发展顺利），不需要服药也能自愈。至于逆症（病情发展凶险），咳嗽且声音嘶哑，饮食吞咽困难受阻，这是第一种恶候。腹部胀满，气短急促，烦躁不安，这是第二种恶候。口渴且腹泻不止，咬牙寒战，这是第三种恶候。痘疮娇嫩容易破损，瘙痒不止，这是第四种恶候。痘色呈紫黑或灰色，痘顶凹陷，气喘且口渴，这是第五种恶候。如果按照上述方法紧急进行救治，十个人中还可以保全活八九个。千万不要因为病情凶险，就放弃治疗。此外还有由轻症变为重症的情况，所触犯的错误有七种：一是不忌口生冷、滑腻的食物，导致脾胃受伤；二是先前曾经腹泻，体内虚弱无法托举毒邪外出；三是过度服用解表药物，或者不避风寒，导致体表之气受损；四是服用寒凉药物，以及胡乱使用攻下里实的药剂，导致体内之气虚寒，毒邪不能发出；五是受到秽浊之气的触碰，详见《种痘说》篇。大概血气闻到香气则顺畅，闻到臭气则逆乱，顺畅则容易出痘和结痂，逆乱则难以痊愈；六是生人频繁到来，以及僧尼穿着孝服的人接触；七是触犯房屋禁忌。又有由重症转为轻症，返凶为吉的情况，需要谨慎注意的五点：一是谨防避开风寒，二是身体保持温和暖和，冷了就添加衣服，热了就减去衣服，务必达到中和的状态，不要令其太过或不及；三是节制饮食，大忌西瓜、柿子、橘子、菱角、水蜜等寒冷食物，恐怕内伤胃气，以及肥肉油腻食物，滑肠导致腹泻，酸咸食物导致口渴，酒、葱、蒜、鱼、羊等腥膻之物导致瘙痒，务必使脾胃充实，那么痘疮就容易发出和结痂；四是保持大便通畅，饮食调和，不导致腹泻，一天一次为调适，一天两三次为通利，适宜紧急使用甘温补脾的药物，如果正值灌浆时期，虽然三四天不大便，不得误认为是便秘；五是按照方法调理，补益气血，顾护脾胃，避开风寒，节制饮食，不要妄自发汗，不要妄自攻下，这样都可以使重症转为轻症，逆转逆症为顺症，或许就不会导致轻症变为重症了。
The body has no significant high fever. The base of the pox is sparse, the roots are red and blooming, there is no diarrhea or thirst, milk and food intake remain unchanged, the four limbs are warm, the voice is clear and bright, the spirit is normal, and the pulse is harmonious and moderate. This belongs to a favorable syndrome (smooth progression of disease), which will heal spontaneously without medication. As for unfavorable syndromes (dangerous progression of disease): coughing with hoarseness and difficulty in swallowing food and drink constitute the first evil sign; abdominal distension with shortness of breath, restlessness and agitation constitute the second evil sign; incessant thirst and diarrhea, teeth grinding and chills constitute the third evil sign; tender pox that easily rupture and unceasing itching constitute the fourth evil sign; purple, black, or gray coloration with sunken tops, panting and thirst constitute the fifth evil sign. If urgent treatment is administered according to the aforementioned methods, eight or nine out of ten patients can still be saved. Do not abandon treatment simply because the condition appears dire. Furthermore, there are seven errors that cause mild conditions to become severe: 1. Failure to avoid raw, cold, slippery, and greasy foods, causing injury to the Spleen and Stomach; 2. Previous diarrhea leading to interior deficiency, unable to push toxins outward; 3. Overuse of exterior-releasing medicines or failure to avoid wind and cold, damaging the exterior Qi; 4. Use of cooling medicines and reckless use of purgatives for interior excess, causing interior Qi deficiency and cold, preventing toxin expulsion; 5. Exposure to foul odors (see "Discussion on Smallpox Vaccination"). Generally, blood and Qi flow smoothly when exposed to fragrant scents but逆流 (reverse) when exposed to foul smells; smooth flow facilitates eruption and crusting, while reverse flow hinders healing; 6. Frequent visits by strangers, and contact with monks, nuns, or those wearing mourning clothes; 7. Violating house taboos. Conversely, severe conditions may turn mild, and misfortune into fortune, provided five precautions are observed: 1. Carefully avoid wind and cold; 2. Keep the body consistently warm; add clothing if cold, remove if hot, aiming for balance, avoiding excess or deficiency; 3. Regulate diet, strictly avoiding cold items like watermelon, persimmon, orange, water chestnut, and honey, which may injure Stomach Qi internally, as well as fatty/greasy foods that cause slippery intestines and diarrhea, sour/salty foods that induce thirst, and pungent/fishy foods like wine, green onion, garlic, fish, and mutton that cause itching; ensure the Spleen and Stomach are robust so pox erupt and crust easily; 4. Maintain regular bowel movements and balanced diet to prevent diarrhea; once daily is considered regulated, two to three times daily is considered free; if urgent need arises, use sweet-warm Spleen-tonifying herbs. During the pus-filling stage, even if there is no bowel movement for three to four days, do not mistakenly diagnose it as constipation; 5. Follow proper regulation: tonify Qi and Blood, protect the Spleen and Stomach, avoid wind and cold, regulate diet, do not induce sweating recklessly, do not purge recklessly. In this way, severe conditions can become mild, and unfavorable conditions favorable, hopefully preventing mild conditions from becoming severe.
