鼾眠者，眠里喉咽间有声也。人喉咙，气上下也，气血若调，虽寤寐不妨宣畅；气有不
和，则冲击喉咽而作声也。其有肥人眠作声者，但肥人气血沉浓，迫隘喉间，涩而不利，亦
人有体气不和，使精液杂秽，故令身体臭也。其汤熨针石，别有正方，补养宣导，今附
《养生方》云∶以手掩口鼻，临日微气，久许时，手中生液，速以手摩面目。常行之，
人腋下臭，如葱豉之气者，亦言诏狐狸之气者，故谓之狐臭。此皆血气不和，蕴积故气臭。
腋下常湿，仍臭生疮，谓之漏腋。此亦是气血不和，为风邪所搏，津液蕴瘀，故令湿臭
丹者，人身体忽然 赤，如丹涂之状，故谓之丹。或发手足，或发腹上，如手掌大，皆
风热恶毒所为。重者亦有疽之类，不急治，则痛不可堪，久乃坏烂，去脓血数升。若发于节
间，便断人四肢；毒入腹，则杀人。小儿得之最忌。
白丹者，初发痒痛，微虚肿，如吹，轸起不痛不赤面白色。由挟风冷，故使色白也。
黑丹者，初发亦痒痛，或 肿起，微黑色，由挟风冷，故色黑也。
赤丹者，初发轸起，大者如连钱，小者如麻豆，肉上栗如鸡冠肌理。由风毒之重，故使
赤也。亦名茱萸丹。
丹轸者，肉色不变，又不热，但起隐轸，相连而微痒，故谓之丹也。
室火丹，初发时必在腓肠，如指大，长三二寸，皮色赤而热是也。
打鼾睡眠，是指人在睡眠时咽喉部位发出声响。人的喉咙是气机上下通行的通道，如果气血调和，即使在清醒或睡眠状态下，气道也能保持通畅；若气机不和，气流冲击咽喉就会发出声音。那些肥胖的人睡觉时发出声响，是因为肥胖之人气血沉滞浓稠，压迫狭窄了喉间通道，导致气行涩滞而不顺畅。
有的人体质之气不和，致使精液混杂秽浊之物，因此身体散发臭味。对于这种情况，用汤药外敷、艾灸、针刺和砭石治疗，另有专门的方剂，此外还有补益调养和导引锻炼的方法，现在附录在《养生方》中：用手捂住口鼻，对着太阳微微呼吸，过一段时间后，手中会产生津液，迅速用手按摩面部。经常这样做，
腋下出汗有异味，像葱豉气味的人，也有人说像狐狸的气味，所以称为狐臭。这些都是因为气血不和，蕴积日久导致气味腥臭。
腋下经常潮湿，并且因臭味而生疮，称为漏腋。这也是因为气血不和，被风邪搏结，津液蕴结瘀滞，所以导致潮湿腥臭。
丹毒，是指人身体突然发红，像涂了丹砂一样，所以称为丹。有的发于手足，有的发于腹部，大小如手掌，都是由风热恶毒所致。严重的也有类似疽的病证，如果不及时救治，就会疼痛难忍，时间久了会溃烂流脓血数升。如果发于关节之间，就会切断人的四肢；毒气入腹，则会致死。小儿患此病最为忌讳。
白丹，初起时瘙痒疼痛，轻微虚肿，像吹胀一样，隆起但不痛不红，面色（皮损处）呈白色。这是因为夹杂风冷邪气，所以颜色发白。
黑丹，初起时也瘙痒疼痛，或者肿胀隆起，微带黑色，这是因为夹杂风冷邪气，所以颜色发黑。
赤丹，初起时红肿隆起，大的像连在一起的铜钱，小的像麻子豆子，皮肤上的颗粒像鸡冠的纹理。这是因为风毒较重，所以使皮肤发红。也称为茱萸丹。
丹疹，肤色不变，也不发热，只是皮下隆起隐现，相连成片且微痒，所以称为丹。
室火丹，初起时一定在小腿肚（腓肠肌），像手指粗细，长二三寸，皮色发红且发热。
Snoring sleep refers to the phenomenon where sounds are produced in the throat and pharynx during sleep. The human throat is the passage for the ascending and descending of Qi (vital energy). If Qi and Blood (Xue) are harmonious, the airway remains unobstructed whether awake or asleep; however, if Qi is disharmonious, its turbulent movement impacts the throat and pharynx, producing sound. In obese individuals who snore, it is because their Qi and Blood are stagnant and dense, compressing and narrowing the throat passage, causing sluggish and obstructed airflow.
Some individuals have a disharmony in their constitutional Qi, causing their essential fluids (Jin Ye) to become mixed with turbid substances, resulting in an offensive body odor. For this condition, treatments such as hot compresses (Tang), moxibustion (Wei), acupuncture (Zhen), and stone lancets (Shi) have specific prescriptions. Additionally, there are methods for tonifying, nourishing, and guiding exercises, which are now appended from the *Yangsheng Fang* (Prescriptions for Nourishing Life): Cover the mouth and nose with hands, breathe gently towards the sun for a period until fluid generates in the hands, then quickly use the hands to massage the face and head. Practicing this regularly...
Those whose armpits emit an odor resembling green onions and fermented soybeans, or some say resembling foxes, are termed "Fox Odor" (Huchou). This is all due to disharmony of Qi and Blood, leading to accumulation and stagnation that causes foul odors.
When the armpits are constantly damp and develop sores due to the odor, it is called "Leaking Armpit" (Louye). This is also caused by disharmony of Qi and Blood, where Wind Pathogens (Feng Xie) bind with the body's defenses, causing Jin Ye to accumulate and stagnate, resulting in dampness and foul odor.
Dan (Erysipelas/Dan toxin) refers to the sudden redness of the body, resembling the application of cinnabar, hence the name Dan. It may appear on the hands and feet, or on the abdomen, with lesions the size of a palm, all caused by toxic wind-heat. Severe cases may resemble Ju (carbuncles/abscesses); if not treated promptly, the pain becomes unbearable, and after a long time, the tissue may rot and discharge several sheng (a traditional unit of volume) of pus and blood. If it occurs at the joints, it can sever the limbs; if the toxin enters the abdomen, it can be fatal. It is most contraindicated for children to contract this disease.
White Dan initially presents with itching and pain, slight swelling, appearing distended like blown-up skin, raised but without severe pain or redness, and the lesion color is white. This is due to the involvement of wind-cold pathogens, which causes the white coloration.
Black Dan also initially presents with itching and pain, or swelling and elevation, with a slightly blackish hue. This is due to the involvement of wind-cold pathogens, which causes the black coloration.
Red Dan initially presents with erythema and elevation. Large lesions resemble connected coins, while small ones resemble hemp seeds or beans. The skin texture resembles chicken combs. This is caused by severe wind-toxin, resulting in redness. It is also known as Cornelian Cherry Dan (Zhuyu Dan).
Dan Zhen (Dan rash) presents with unchanged skin color and no heat sensation, but with subcutaneous elevations that are contiguous and mildly itchy, hence named Dan.
Shihuo Dan (Chamber Fire Dan) initially appears on the gastrocnemius muscle (calf), about the thickness of a finger and two to three cun in length, with red and hot skin.
