The diseases of men and women can be known through inquiry and obtained through pulse diagnosis. One can determine life and death, distinguish between difficult and easy cases, and assess the severity of the illness, all with a basis, thus avoiding major errors. However, for infants and children, although they suffer while being held in their parents' arms, they cannot speak; and when they learn to talk, they still cannot point out where it hurts. To diagnose their pulse, since their bones are short and small, and their qi and blood are not yet sufficient, how can the Cun (inch), Guan (bar), and Chi (cubit) positions be distinguished? How can the Floating (Fu), Middle (Zhong), and Deep (Chen) depths be determined? Although there is a theory of using one finger to roll and take two positions, one ultimately fails to grasp the correct pulse position. Moreover, since the pulse rate is rapid, how can it be fully examined? Generally, 8-9 beats per breath cycle is a normal pulse, 5-6 beats is a slow pulse, and 11-12 beats is a rapid pulse; these distinctions are merely vague and approximate. Therefore, the difficulty of treating pediatric diseases is often ten times that of adults, and extreme caution is required. Only the pulse at the Tiger's Mouth (Hu Kou) is somewhat verifiable. This pulse is located on the lateral side of the index finger. Each segment corresponds to a Guan (pass), and three segments constitute three Guans. For males, the left hand is observed; for females, the right hand. There is a vein resembling a thread tied within the flesh, which must be observed carefully: purple indicates Wind syndrome, red indicates Cold Damage (Shang Han), green/cyan indicates Fright syndrome, white indicates Gan accumulation (parasitic disease or malnutrition), yellow indicates Spleen distress, and cyan-black indicates Slow Convulsion syndrome. If the pulse pattern extends into the palm, it indicates Internal Torsion (Nei Diao). If the three Guans are connected and extend to the nail tip, it is a sign of Deep Cold. Only this aspect can be slightly understood. Nevertheless, when treating pediatric diseases, one should seek information from multiple sources. How can one rely solely on the Tiger's Mouth pulse method to diagnose all pediatric diseases? One must observe attentively before symptoms manifest, so as to prevent the disease in its early stages. For instance, continuous yawning in children indicates that the zang-fu organs are affected by pathogenic factors, marking the onset of illness. If the face is red, it indicates Wind-Heat, and Liver-draining formulas can be administered first. If the face is cyan, it indicates Fright-Wind, and formulas for calming fright can be used first. If the face is yellow, it indicates Spleen deficiency, and Spleen-tonifying formulas can be used first. Excessive sleepiness indicates internal heat, and heat-clearing formulas can be used first. Hot breath from the mouth indicates Wind-Cold attack, and wind-dispersing formulas can be used first. Treatment should always precede the full manifestation of symptoms based on the clinical presentation, rather than waiting for the disease to develop before administering medication. One must also know those incurable conditions. The following are ten incurable signs: 1. Red vessels on the eyelids, or bulging/sunken fontanelle. 2. Fish-mouth odor with coarse breathing, teeth grinding, or biting people. 3. Cold sweat like rain with persistent phlegm-heat. 4. Umbilical wind with mouth puckering, locked abdomen, or intestinal torsion. 5. Pathogenic wind attacking the jaw and chin, with swollen and hard lips and neck. 6. Black coloration on the nose. 7. Coughing, wheezing, accompanied by heart pain. 8. Edema of the four limbs. 9. High and protruding chest. 10. Five Softnesses (Wu Ruan) and Five Stiffnesses (Wu Ying). Upon seeing such signs, one should cease treatment. If one fails to do so promptly and continues to administer medicine, although the patient's death may not be directly attributed to me, I would have no excuse to offer to the family. Generally, pediatric diseases follow certain patterns. Most frequently, inability to get what one wants leads to anger and crying, hence Liver diseases are common. Lack of dietary moderation, craving food even after being full, leads to frequent Spleen diseases. Unsettled mind and spirit, easily startled by noise, lead to frequent Fright diseases. A nature fond of sucking milk, with stagnation of sweet foods leading to susceptibility to Wind-Heat, results in frequent Phlegm diseases. When treating pediatric illnesses, one should examine these common patterns, apply judgment, combine one's own understanding with the specific condition of the disease, and thereby minimize medication errors. Although these types are common, Liver and Spleen diseases are particularly prevalent. Profound understanding depends on the individual practitioner; the state of mental acuity and manual dexterity cannot be fully conveyed through words.
