凡煎药必须择亲信诚谨老实之人，洗净新药罐，用新汲甜水为上，慢火煎熬，纱
绢滤渣，取清汁服之。不可近灯火之下吃药，过口之物，酸味过口，则药味甘甜，甜
物过口，则药味转苦。又不宜服冷药，脾喜热，冷则不能营运。患在上，不厌频而
少，少服则滋荣于上；患在下，不厌顿而多，多服则峻补于下。病在头面、颈项、臂
膊者，先食而后药；病在胸膈、心下、肚
腹、膀膝者，先药而后食；病在四肢者，阳中之阳，须服药于旦；病在骨髓，阴中之
阴，须服药于夜。
凡病时，忌怒，忌疑虑，忌身体不洁人来看，忌鱼、羊、鹅肉、烧酒、面食、生
冷瓜果、腌腊等物，疮口敛百日后，不作渴者，方可入房。
凡一切痈疽疮肿毒证，将欲好之时，如往有丧人家吊孝，并拜望等项，其疮肿即
复发，切忌，切忌。
凡痈疽大证，虽有姬外家，不得艳装相见，每见痈疽溃后，大肉已生，姬外家往来，
虽无交接之事，而欲念一动，精已离宫，每致虚陷喘急而亡者数人。病者当惜生命，不
可不为拒绝也。
凡视疮疡，秽气甚臭，闻之则恶心难忍，毒深者，最能染人。须先用绵纸塞鼻
孔，食姜、蒜、烧酒、充饱之物，以敌秽气，切不可空心视之。吃蒜、酒后，不可
口对疮上，恐秽气触疮上，令患者作痛。
煎药必须选择亲近、诚信、谨慎且老实的人来操作，洗净新的药罐，以新汲取的甘甜泉水为最佳，用慢火煎熬，用纱绢过滤掉药渣，取清澈的药汁服用。服药时不可靠近灯火之下，吃过酸味食物后再服药，则药味会变得甘甜；吃过甜物后再服药，则药味会转为苦涩。也不宜服用冷药，因为脾脏喜欢温热，寒冷则不能正常运化水谷精微。病变部位在上焦（如头面胸膈），不厌其烦地少量多次服用，少量服用能使滋养之气上行；病变部位在下焦（如腹部四肢），不厌恶顿服且剂量较大，大量服用能峻补下焦。病位在头面、颈项、胳膊的，先吃饭后服药；病位在胸膈、心下、肚腹、膝盖的，先服药后吃饭；病在四肢的，属于阳中之阳，必须在早晨服药；病在骨髓的，属于阴中之阴，必须在夜间服药。
患病期间，忌发怒，忌疑虑，忌身体不洁的人来看望，忌吃鱼、羊肉、鹅肉、烧酒、面食、生冷瓜果、腌腊制品等食物。疮口愈合一百天后，如果不感到口渴，才可以进行房事。
凡是各种痈疽疮肿毒证，在即将痊愈的时候，如果去丧家吊唁或拜望等，疮肿就会立即复发，千万切忌，千万切忌。
凡是严重的痈疽大证，即使有姬妾外室，也不得盛装相见。常见痈疽溃烂后，虽然大肉已生（伤口开始长肉），但姬妾外室往来接触，虽然没有发生性行为，但只要欲念一动，精气就已经离宫耗散，往往导致患者因虚陷喘急而死亡的人数不少。病人应当爱惜生命，不可不加以拒绝。
凡是诊视疮疡，秽气非常臭，闻之让人恶心难忍，毒邪深重的，最能传染给人。必须先用绵纸塞住鼻孔，吃姜、蒜、烧酒以及吃饱食物，以抵御秽气，切不可空腹诊视。吃了蒜、酒后，不可对着疮口呼气，恐怕秽气触碰到疮口，令患者感到疼痛。
Decoction of herbs must be prepared by a trusted, honest, cautious, and reliable person. The new herbal pot should be washed clean, and the best water to use is fresh, sweet well water. It should be simmered slowly over low heat, filtered through gauze or silk to remove dregs, and the clear decoction taken. One should not take medicine under the light of a lamp. If sour food has been consumed before taking medicine, the taste of the medicine will become sweet; if sweet food has been consumed, the taste of the medicine will turn bitter. Cold medicine should also be avoided, as the Spleen (Zang organ) prefers warmth; coldness impairs its transportive and transformative functions. For diseases located in the upper part of the body, frequent but small doses are preferred; small doses nourish and ascend to the upper jiao. For diseases located in the lower part of the body, large single doses are acceptable; large doses strongly tonify the lower jiao. For diseases in the head, face, neck, and arms, eat first and then take medicine; for diseases in the chest, diaphragm, epigastrium, abdomen, and knees, take medicine first and then eat. For diseases in the four limbs, which belong to "Yang within Yang," medicine should be taken in the morning; for diseases in the bone marrow, which belong to "Yin within Yin," medicine should be taken at night.
During illness, one must avoid anger, worry, and visits from people with unclean bodies. Dietary taboos include fish, mutton, goose meat, distilled liquor, wheat flour products, raw and cold fruits and vegetables, and cured meats. After a sore has healed for 100 days and the patient does not feel thirsty, sexual intercourse may resume.
For all types of carbuncles, ulcers, sores, and toxic swellings, when they are about to heal, visiting mourning households or paying respects can cause immediate recurrence of the swelling. This must be strictly avoided.
In severe cases of carbuncles and ulcers, even concubines or female guests should not meet the patient dressed attractively. It is often seen that after a carbuncle ulcerates and flesh begins to regenerate, interactions with concubines or female guests, even without sexual contact, can trigger lustful thoughts. Once desire arises, essence (Jing) leaves its palace, often leading to death due to deficiency collapse and panting. Patients must cherish their lives and firmly refuse such interactions.
When examining sores and ulcers, the foul odor is strong and nauseating; deep toxicity can easily infect others. One should first plug the nostrils with cotton paper, consume ginger, garlic, distilled liquor, and fill the stomach with food to counteract the foul air. One must never examine sores on an empty stomach. After eating garlic or drinking liquor, one must not breathe directly onto the sore, lest the foul air touch the wound and cause pain to the patient.
