《内经》有谓汗之则疮已者,谓温胜皮肤为疥癣者也。治当饮以凉肌、和血、散湿热怫郁在皮肤之药;
外以杀虫、润燥、解痰涎凝结腠理之药敷之。仲景谓∶疮不可汗,汗之则作 。此热郁肌肉,血腐为疮,
宜解郁热也。或饮食之积所致,皆不宜汗,热有浅深故也。疡即头疮,乃火热上炎,当治火于上,内使
之降,外令其散,亦敷以杀虫,退热之剂。世方皆得以治,不足深论。
酒热所致乎?曰∶不然。不饮者,亦病此。盖鼻者肺窍,而足阳明侠鼻上至目内 ,其位居面
之中,属土,为呼吸气息出入之门户,气血之精明者,皆上注于面,入于其窍。故胃中湿热与中焦热
所化之血,上输于肺,随呼吸之息,熏蒸鼻端,凝结皮肤,遂成红赤、甚则盈面,不独在鼻也。予尝
以凌霄花为末,和密陀僧,唾调敷,甚妙。
安神之外,犹可论否?曰∶方论虽言怵惕思虑所伤,忧欲过损,惊恐伤心,心伤则健忘也。予尝
思之,人生气禀不同,得气之清,则心之知觉者灵;得气之浊,则心之知觉者昏。心之灵者,无有限量,
虽千百世已往之事,一过目则终身记之而不忘;心之昏者,虽无所伤,而目前事亦不能记矣。刘河间谓
水清明,火昏浊。故上善若水,下愚若火,此禀质使然。设禀清浊混者,则不能耐事烦扰,烦扰则失其
灵而健忘。盖
血与气,人之神也。经曰∶静则神藏,躁则消亡。静乃水之体,躁乃火之用,故性静则心存于中,动
则心忘于外,动不已则忘不已,忘不已则存于中者几希,故语后便忘,不俟终日。所以老人多忘,盖由
役役扰扰纷纭交错,气血之阴于斯将竭,求其清明有所守。而不为事物所乱者,百无一人焉!由是言之,
药固有安心养血之功,不若平心易气,养其在己而已。设使因痰健忘,乃一时之病,亦非独痰也。凡心
有所寄与诸火热伤乱,其心皆健忘也。《灵枢》谓盛恐伤志,志喜忘。《内经》谓血并于下,气并于上,
乱而喜忘。可不各从所由以治之哉?
The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states that "sweating will cure sores," referring to scabies and tinea caused by the predominance of warm-heat pathogens affecting the skin. Treatment should involve internal administration of herbs that cool the skin, harmonize the blood, and dissipate damp-heat stagnation in the skin; externally, herbs that kill parasites, moisten dryness, and resolve phlegm-saliva condensation in the couli (interstices) should be applied as a poultice. Zhang Zhongjing stated: "Sores must not be treated with sweating; if sweating is used, it will induce convulsions." This is because heat is stagnant in the muscles, causing blood corruption and sore formation, which requires resolving the stagnant heat. Alternatively, it may be caused by food accumulation; in all these cases, sweating is contraindicated due to the varying depth of heat.
Head sores refer to sores on the head, caused by fire-heat flaming upward. Treatment should focus on clearing fire from the upper body, causing it to descend internally and disperse externally, while also applying external agents that kill parasites and reduce heat. Common prescriptions in the world can treat this condition, so there is no need for deep discussion.
Is alcoholic rhinophyma (red nose) caused by excessive alcohol consumption? The answer is: No. Those who do not drink also suffer from this disease. The nose is the orifice of the Lung Meridian of Hand-Taiyin (Lung). The Foot-Yangming Stomach Meridian runs alongside the nose up to the inner canthus of the eye. Its location is in the center of the face, belonging to Earth, serving as the gateway for the entry and exit of breath. The essence of Qi and Blood ascends to the face and enters its orifices. Therefore, damp-heat in the Stomach and blood transformed by heat in the Middle Jiao ascend to the Lung, and through respiration, steam the nasal tip, condensing in the skin, resulting in redness, which may even cover the entire face, not just the nose. I once used powder of Lonicera Japonica Flos (Lingxiao Hua) mixed with Lithargyri Pulvis (Mituo Seng), adjusted with saliva for topical application, which was very effective.
Apart from calming the Spirit, is there anything else to discuss? The answer is: Although medical texts state that fright, fear, and overthinking damage the Heart-Spirit, and that excessive worry and desire deplete the Heart, leading to forgetfulness when the Heart is injured, I have pondered this. People are born with different constitutions. Those who receive clear Qi have sharp mental perception; those who receive turbid Qi have dull mental perception. A sharp mind has no limits; even events from thousands of years ago, once seen, are remembered for life without forgetting. A dull mind, even without injury, cannot remember current events. Liu Wansu said water is clear and bright, while fire is dim and turbid. Thus, the wise are like water, and the foolish are like fire; this is determined by innate constitution. If one's constitution is a mix of clear and turbid, they cannot endure mental disturbance; disturbance causes the loss of mental clarity, leading to forgetfulness.
Blood and Qi constitute the substance of the human Shen (Spirit). The Classics state: "Stillness allows the Shen to reside within; agitation causes the Shen to perish." Stillness is the nature of Water; agitation is the function of Fire. Therefore, a calm nature keeps the Heart-Spirit within, while an agitated nature causes the Heart-Spirit to wander outward. Continuous agitation leads to continuous forgetting; persistent forgetting depletes the Shen stored within. Hence, one forgets immediately after speaking, unable to last until the end of the day. The elderly often suffer from forgetfulness because their days are filled with busy distractions and chaotic interactions. Their Yin Essence of Qi and Blood is nearly exhausted, making it rare for them to maintain clarity and remain undisturbed by external affairs. From this perspective, although medicines have the merit of calming the Heart and nourishing Blood, they are inferior to calming the mind and regulating Qi, and cultivating one's own nature. If forgetfulness is caused by Phlegm, it is a temporary condition, but not solely due to Phlegm. Any situation where the Heart is attached to something or disturbed by various Heat pathogens results in forgetfulness. The *Lingshu* states that excessive anger injures Zhi (Will), and injury to Zhi leads to forgetfulness. The *Neijing* states that when Blood congregates below and Qi congregates above, confusion arises, leading to a tendency to forget. Should we not treat each case according to its specific cause?
