浪华菱屋素闲，六十多岁，身体消瘦且无法进食。起初是因为饮食积滞致病，各位医生用香砂六君子汤、七味白术散治疗，都没有效果。北山友松给他用了异效散加汉当归（当归），两三帖药就好了。又有金田铺某位女子不想吃谷物，只吃其他东西，各种治疗都无效。于是给她用四物汤，加入人参、白术、橘皮，病就好了。门人问其中的缘故，他说：“脾胃血液虚弱就会干枯燥涩，导致不能进食。”汉当归味甘，能够补益脾中的血，所以它是促进进食的药剂。《内经》说：“手得到血就能抓握，脚得到血就能行走，肝得到血就能视物”，据此推断，原文中“肝得血而能视”之下应当补充“胃得到血就能进食”这一句。
瘫痪多年的人，一旦突然手足活动，眼睛明亮有神，这是病情急剧变化的征兆。
久病以及极度虚弱的人，如果尺部肌肉脱陷，以及手指头不能迅速弯曲的，大多属于难治之症。（片仓鹤陵说：凡是病人肌肉枯瘦，手腕后方肌肉脱陷且形状扁平，医生握住其中指和无名指试图让它们合拢的，无论患什么病都是死兆。即使饮食如常，这也是游魂假借呼吸罢了。劳瘵（肺结核）这类病，经过几个月后必然会出现这种征候。只有伤寒、痢疾、香港脚（脚气病）之后出现这种征候的，往往能痊愈，大概是因为本源未绝。）
《脉要》的宗旨在于《颐生微论》，不可另求他法，只有本草书中揭示脉理的地方也可以一并阅读。
对于痢疾、呕吐、呃逆等药物无法入口的患者，单用黄连一味药小剂量服用，待药食都能服下后见到蛔虫证候，因此前方配合大七气汤给予患者，这种方法本于薛氏治疗太宜人的医案。
友松所著的《医方口诀集》，是编纂言论和方剂考证的首部著作。读后深知其学术渊博，运用自如。唯独到了《北山医案》，只是模仿古人，拘泥于法度，终究缺乏高逸的气韵。学习者读它可以，不读也可以。
Ryōya Sokan from Naniwa was over sixty years old, emaciated and unable to eat. Initially, his condition resulted from food stagnation (Shangshi). Various physicians treated him with Xiangsha Liujunzi Tang (Aromatic Sandalwood Six Gentlemen Decoction) and Qiwei Baizhu San (Seven-Ingredient Atractylodes Macrocephala Powder), but to no avail. Yumatsu administered Yixiao San (Heterogeneous Efficacy Powder) combined with Danggui (Angelica sinensis), and he recovered after two or three doses.
Another case involved a woman from the Kimuta shop who refused grain food, consuming only other substances. All treatments failed. Yumatsu prescribed Siwu Tang (Four Substances Decoction) supplemented with Renshen (Ginseng), Baizhu (Atractylodes macrocephala), and Jupi (Tangerine Peel), resulting in her recovery. When disciples asked for the rationale, he explained: "When the blood of the Spleen and Stomach is deficient, dryness and lack of moisture prevent eating." Danggui has a sweet flavor and can tonify the blood within the Spleen; thus, it serves as an agent to promote appetite. The Classic states: "The hands grasp when they receive blood; the feet walk when they receive blood; the eyes see when the Liver receives blood." Based on this, one may infer that the text should originally have included the phrase "the Stomach eats when it receives blood" following "the eyes see when the Liver receives blood."
Daqi Qi Tang (Great Seven-Qi Decoction) is used to treat persistent coughing in women; its underlying principle is worth pondering.
In cases of paralysis lasting for years, if the patient suddenly exhibits movement of the limbs and bright, clear eyes, it indicates an acute change in the condition (a critical sign).
For patients with chronic illness or extreme deficiency, if the flesh at the Chi pulse position (wrist area corresponding to Kidney/Yin) is sunken, and the fingertips cannot flex rapidly, the prognosis is generally poor. (Kuranaka Kaku-ryō stated: "Whenever a patient presents with emaciated muscles, sunken flesh behind the wrist with a flat appearance, and inability to approximate the middle and ring fingers when grasped by the physician, regardless of the disease, it is a death omen. Even if dietary intake remains normal, this is merely the breath of a wandering soul. In cases of Laozai (consumption/tuberculosis), this sign inevitably appears after several months. However, in cases following Shanghan (Cold Damage), Liji (Dysentery), or Hongxiangjiao (Beriberi/Edema), recovery is often possible, likely because the root vitality remains.")
The *Mai Yao* (Essentials of Pulse Diagnosis) aims to elucidate the principles of preserving life found in *Yisheng Weilun*; no other approach is necessary. One may also read sections on pulse diagnosis within Materia Medica texts.
For dysentery, vomiting, or hiccups where medicines cannot be retained, administering a small dose of single-ingredient Huanglian (Coptis chinensis) allows both medicine and food to be taken. If signs of roundworms (Hui Zheng) appear thereafter, combining the previous formula with Daqi Qi Tang is effective. This method originates from Drue's treatment of Lady Taiyi.
Yumatsu’s *Yifang Koujue Ji* (Collection of Mnemonics for Medical Formulas) is a pioneering work compiling theories and formula analyses. Reading it reveals profound academic wealth and effortless mastery. However, regarding his *Beishan Yi An* (Medical Cases of Beishan), it merely imitates ancients and rigidly adheres to rules, ultimately lacking elevated and unrestrained spirit. It is acceptable for learners to read it, but omission is also permissible.
