In the medical field, pediatric treatment is the most difficult. The intestines and stomach are fragile and prone to injury from milk and food; the bones and tendons are tender and easily affected by wind and cold. Prone to deficiency or excess, changes occur as quickly as flipping a hand; whether tonifying or purging, flexibility is crucial, like turning a pill. Salty flavors often deplete Kidney Qi, while excessive sour flavors support Liver Qi. Bitter flavors enter the Heart but their cold nature damages the Stomach; pungent flavors travel to the Lung but their dryness and heat damage Yuan Qi. To seek a balanced approach, nothing surpasses flat-natured sweet herbs. If the condition requires sudden dizziness (mingxuan) from potent drugs, do not fear their toxicity; if adopting temporary symptomatic treatment, only seek efficacy. Stop medication once it hits the disease, prioritizing the rescue of the root. Misprescribing decoctions immediately leads to damage and disability. This is the oath of superior physicians to save lives, and the verification of good doctors through practice!

It has been heard that methods are not fixed, but depend on symptoms; if one is not a physician from three generations, do not administer decoctions or pills. Patients should carefully select skilled practitioners, and physicians must strive for cure. View illness as if it were one's own, and do not be greedy for profit. First observe the influence of climate (Yunqi), skillfully aligning with Yangming mechanisms; then observe complexion and physique, clearly understanding favorable and unfavorable trends. In spring and summer, when Yang is abundant, bitter-cold herbs can be used, depending on the patient's robustness; in autumn and winter, when Yin is abundant, pungent-warm herbs can be considered, based on the patient's fatigue and gan syndrome. If warming is needed but cold is used, or if dispersal is needed but warmth is applied, the Seven Spirits will scatter, and the Five Zang organs will collapse. Although paying attention to pulse and prescription studies, what benefit does it bring to the world? Instead causing premature death, this incurs heavenly retribution. Therefore, for congenital diseases, urgent detoxification is required; for food stagnation, eliminating gan syndrome is beneficial. Treatment divides into two methods, achieving perfect efficacy. For infants still unsettled in swaddling clothes, regulate the mother; for toddlers walking unsteadily, consolidate their Yuan Qi.

Alas, the harmonious center of the intestines and stomach cannot withstand medicinal attacks; subtle is the weak and immature Qi and Blood, which develop gradually. Treatment is not out of desperation, but because diseases strike suddenly. Like protecting a candle in the wind, the heart remains vigilant; like cherishing a pearl in the palm, the intention is sincere. Physicians can supplement the Lord of Life, without disgracing family traditions.

For instance, when illness arises, heat emerges; when heat rises, fright occurs. Some treat heat with heat, others attack heat with cold. If heat is in the exterior, Chai Ge Jie Ji Tang (Bupleurum and Pueraria Muscle-Releasing Decoction) can be drunk; if heat is in the interior, Qin Lian Xiao Du Tang (Scutellaria and Coptis Detoxifying Decoction) should be boiled urgently. For accumulated heat, Ji Sheng Wan (Ji Sheng Pill) is unparalleled; for deficient heat, Tiao Yuan Tang (Regulating Yuan Decoction) is excellent. The key lies in recognizing pulses and colors, not recklessly administering decoctions or pills, lest leaving lifelong chronic diseases or shortening the infant's lifespan. Mild conditions becoming severe, the merit does not offset the harm. Merely entrusting fate to destiny, without carefully studying classics. The previous cart overturned, yet the tracks remain the same. Souls wander in the suburbs, cries reach the rivers. Knowing this cause, whose fault is it? Alas! Building bridges for ants, freeing sparrows from cages. How much more so for spirits among all things, not worth less than a worm, if not cautious and meticulous, they are lightly sacrificed. Extending compassionate conscience, as if seeing someone fall into a well; examining sages' teachings, as if fearing failure to save them. Living in ease implies danger, knowing falls teaches caution. Symptoms emerge in hundreds of ways, treatments avoid bias. Harmonize and transform creation, preserve true Yuan. Good offense is inferior to good defense, urgency is preferable to slowness. Planting apricots to form a forest, following Dong Feng of old; planting oranges naming a well, seeing Su Dan of today.

Why does prolonged diarrhea become dysentery, prolonged stagnation become gan syndrome, prolonged malaria produce masses, prolonged fright turn into abscesses? Before lingering sets in, attack should be swift; once severe illness appears, treatment should be gentle. Intestines and stomach blocked, urgently purge; Qi and Blood deficient and emaciated, urgently tonify to stabilize. External toxins attacked urgently, preventing entry into the abdomen; exterior pathogens resolved urgently, preventing further transmission. Others are regulated slowly, fearing rapid changes; once medicine is swallowed, prevent overdose; if treatment hits the disease, do not exaggerate ability. The wise often worry about one mistake, the dead cannot be restored. Better to be cautious before error than regret after misjudgment. To seek fish and rabbits, hold onto the trap and basket. If treating diseases with multiple methods, repeat these words thrice!
