夫人既以五谷养其生，而亦药石伐其病。苟无药石，则寒暑劳苦之太过，喜怒饥饱之无节，
时令不常，卫生无术，身贫而莫求医药，虽富者或无良剂，或客游半道，卧病而无所治疗，如是
而夹者亦多矣。且好仁之士，有济物之心，或蓄一验方，或有一奇药，计力多寡，精加修制，广

春甫曰∶圣人治未病不治已病，非谓已病而不治，亦非谓已病而不能治也。盖谓治未病，在
谨厥始防厥微以治之，则成功多而受害少也。惟治于始微之际，则不至于已着而后治之，亦自无
已病而后治也。今人治已病不治未病，盖谓病形未着，不加慎防，直待病势已着，而后求医以治
之，则其微之不谨，以至于着，斯可见矣。
圣人起居动履，罔不摄养有方。间有几微隐晦之疾，必加意以防之，用药以治之。圣人之治
未病不治已病有如此。《论语》曰∶子之所慎，齐、战、疾。释云∶齐，所以交神明，诚至而神
格，疾为身之生死所关，战为国家存亡所系。然此三慎诚为最大，而疾与乎其中，得非以身为至
重耶？康子具药，则曰∶未达，不尝。可见圣人慎疾慎医之心至且尽矣。
世之人非惟不知治未病，及至已病，尚不知谨，始初微略，恣意无忌，酿成大患，方急而求
医，曾不加择，惟以其风闻，或凭其吹荐，委之狂愚，卒以自坏。皆其平日慢不究心于医，至于
仓卒，不暇择请。殊不知医药人人所必用，虽圣人有所不免。顾在平昔讲求，稔知其为明医，偶
有微疾，则速求之以药，治如反掌。譬能曲突徙薪，岂有焦头烂额之诮？丹溪论之，固亦详矣。
甫之肤见，尤有未悉之意焉。续貂之讶，诚所不免。有志养生者，扩而充之，亦未必无小补云。
人既然依靠五谷来滋养生命，同时也依靠药物来祛除疾病。如果没有药物，那么寒暑劳累之苦过度，喜怒饥饱没有节制，时令变化无常，缺乏养生之术，身体贫困无法寻求医药，即使富有的人也可能没有好的药方，或者客居他乡半路患病而无处治疗，像这样导致死亡的人也很多了。况且那些崇尚仁德的人士，怀有救助万物之心，有的珍藏一个有效的药方，或拥有一种奇特的药材，根据力量大小，精心加以炮制加工，广泛地施予恩惠，使那些长期顽固的疾病、痛苦万状、情况危急恶劣的病症，通过一种药物就能痊愈，让呻吟之声变为和乐之气。虽然自身贫困力量微薄，难以亲自配制药物救济他人的人，如果能得到奇效的药方，随着所治疗的疾病，印刷千百本，张贴在墙壁道路之间，利益也是很大的。
春甫说：圣人治理未病而不治理已病，并不是说已经生病就不去治疗，也不是说已经生病就不能治疗。而是说治理未病，在于谨慎其开始，防止其微小之处从而进行治疗，这样成功多而受害少。只有在疾病处于初始微小的时候进行治疗，就不会发展到病情明显后才去治疗，自然也就没有等到已经生病后才去治疗的情况了。现在的人只治疗已病而不治理未病，大概是因为病形尚未显露，不加谨慎防范，一直等到病势已经明显，才去求医治疗，这种对微小之处的不谨慎，以至于发展到明显程度，就可以看出来了。
圣人的起居行动，无不摄生调养有方法。间或有极其细微隐蔽的疾病，必定加意去预防它，用药去治疗它。圣人治理未病而不治理已病就像这样。《论语》说：孔子所谨慎的事情，是斋戒、战争、疾病。解释说：斋戒，是用来与神明相交，诚意达到极致则神明降临，疾病关乎身体的生死，战争关乎国家的存亡。然而这三件事确实是最为重要的，而疾病也在其中，难道不是把身体看得最重吗？康子准备了药物，却说：“还没有弄清楚（药性），不敢尝试。”可见圣人谨慎对待疾病和医生的心意到了极点且完备了。
世上的人不仅不知道治理未病，等到已经生病，尚且不知道谨慎，起初轻微疏忽，肆意无忌，酿成大祸，才急忙求医，竟然不加选择，只凭道听途说，或者凭借别人的吹捧推荐，委托给狂妄愚昧的人，最终导致自我败坏。这都是因为他们平日怠慢，不在医学上用心研究，到了仓促之间，来不及选择聘请。殊不知医药是人人必须使用的，即使是圣人也不能避免。关键在于平时讲求，熟知他是名医，偶然有了小病，就迅速求取他的药物，治疗起来易如反掌。假如能像曲突徙薪那样提前预防，怎么会有焦头烂额的讥笑呢？丹溪对此论述得很详细了。
我肤浅的见解，尤其还有未能详尽的意思。被嘲笑续貂（比喻好坏混杂），实在不能避免。有志于养生的人，扩充并充实这些内容，也未必没有小小的补益。
Since humans rely on the five grains to nourish their lives, they also rely on medicinal herbs and stones to eliminate diseases. If there were no medicines, then excessive cold, heat, labor, and hardship, along with unregulated anger, joy, hunger, and fullness, unpredictable seasonal changes, and a lack of health preservation techniques, would lead to situations where the poor cannot seek medical care, and even the wealthy might lack good prescriptions, or fall ill while traveling far from home without treatment. In such cases, many people would perish. Moreover, those who advocate benevolence possess a heart to aid all things; some may hoard a proven prescription or possess a unique herb. Depending on their capacity, they carefully process and prepare these remedies, widely distributing them to benefit others, so that chronic stubborn diseases, agonizing conditions, and critical states can be cured by a single medicine, turning groans into harmony. Even for those who are poor and weak, unable to personally compound and distribute medicines, if they can obtain effective prescriptions, print thousands of copies according to the diseases treated, and paste them on walls and roadsides, the benefit will be extensive.
Chunfu said: The sages treat disease before it arises rather than after it has arisen. This does not mean that existing diseases are left untreated, nor does it mean that existing diseases cannot be treated. It means that treating disease before it arises involves being cautious at the beginning and preventing it when it is minute, thereby achieving success with minimal harm. By treating it at the initial, minute stage, one avoids waiting until the disease is manifest to treat it, thus naturally avoiding the need to treat only after the disease has fully developed. Nowadays, people treat only existing diseases and do not prevent future ones. This is because when the signs of disease have not yet manifested, they fail to exercise caution, waiting until the disease trend is obvious before seeking medical treatment. This shows how negligence at the minute stage leads to manifestation.
The sages' daily activities and movements were always guided by proper health preservation methods. When there were even slightly subtle or hidden ailments, they paid special attention to preventing them and used medicine to treat them. This is how the sages treated disease before it arose rather than after. The *Analects* states: "What Confucius was careful about were fasting, war, and illness." The explanation says: Fasting is used to communicate with spirits; when sincerity reaches its peak, spirits descend. Illness concerns life and death of the body, while war concerns the survival or destruction of the state. These three areas of caution are indeed the greatest, and illness is among them. Does this not indicate that the body is regarded as extremely precious? When Duke Kang prepared medicine, he said, "I do not yet understand it, so I dare not taste it." This shows that the sages' caution regarding illness and physicians was utmost and complete.
People in the world not only fail to know how to treat disease before it arises, but even when already ill, they remain careless. Initially slight negligence, indulging without restraint, brews major disasters. Only then do they hastily seek doctors, without any selection, relying merely on hearsay or recommendations, entrusting their health to reckless and ignorant individuals, ultimately leading to self-destruction. This is because they neglect medicine in their daily lives and fail to study it seriously, leaving them no time to choose wisely in emergencies. They do not realize that medicine is essential for everyone, including sages. The key lies in studying it beforehand and becoming familiar with qualified physicians. If minor illnesses occur, one should quickly seek their medication, making treatment as easy as turning over a hand. If one could act like bending the chimney and moving the firewood (taking preventive measures), how could one suffer the ridicule of having scorched heads and broken limbs (dealing with consequences)? Danxi discussed this in detail.
My superficial views certainly contain omissions. The criticism of adding dog's tails to a fine fur coat (inferior additions) is unavoidable. Those interested in health preservation may expand upon and enrich these ideas, which may provide some small benefit.
