扁鹊曰∶人一息脉二至谓平脉，体形无苦。人一息脉三至谓病脉。一息四至谓痹者，脱脉气，其眼睛青者，死。人
一息脉五至以上，死，不可治也。都（一作声）息病，脉来动，取极五至，病有六、七至也。
扁鹊曰∶平和之气，不缓不急，不滑不涩，不存不亡，不短不长，不俯不仰，不从不横，此谓平脉，肾（一作紧）
受如此（一作刚），身无苦也。
扁鹊曰∶脉气弦急，病在肝。少食多厌，里急多言，头眩目痛，腹满，筋挛，癫疾上气，少腹积坚，时时唾血，咽
喉中干。相病之法，视色听声，观病之所在，候脉要诀岂不微乎？脉浮如数，无热者，风也。若浮如数，而有热者，气
也，脉洪大者，又两乳房动，脉复数，加有寒热，此伤寒病也。若羸长病，如脉浮溢寸口，复有微热，此疰气病也，如
复咳又多热，乍剧乍瘥，难治也。又疗无剧者，易瘥；不咳者，易治也。

Bian Que said: When a person's pulse beats twice per breath, it is called the normal pulse (Ping Mai), and the body suffers no pain. When the pulse beats three times per breath, it is called the disease pulse. When the pulse beats four times per breath in a Bi syndrome patient, this indicates exhaustion of pulse qi (Tuo Mai Qi); if the eyes are blue-green, death will ensue. If the pulse beats five times or more per breath, death occurs and it is incurable. In cases of vocal abnormalities where the pulse comes with agitation, taking an extreme rapid pulse reaching five beats per breath, the condition may worsen to six or seven beats per breath.
Bian Que said: The harmonious Qi is neither slow nor fast, neither slippery nor choppy, neither existing nor absent, neither short nor long, neither bowing nor rising, neither longitudinal nor transverse; this is called the normal pulse. If the Kidney (or Tense pulse) presents thus, the body suffers no pain.
Bian Que said: A string-tight and rapid pulse indicates disease in the Liver. Symptoms include reduced appetite and aversion to food, abdominal tension with excessive talking, dizziness and eye pain, abdominal fullness, tendon contraction, epilepsy with rebellious Qi, hard accumulations in the lower abdomen, frequent spitting of blood, and dryness in the throat. The method for diagnosing disease involves observing complexion, listening to voice, and viewing the location of the illness. Are not the essential principles of pulse diagnosis subtle? A floating pulse resembling a rapid one without fever indicates Wind pathogen. If the pulse is floating and rapid with fever, it indicates Qi stagnation. If the pulse is洪大 (Hong Da, large and forceful), accompanied by pulsation in both breasts, further rapidity, and alternating chills and fever, this is Shang Han Bing (Cold Damage Disease). In chronic wasting diseases, if the pulse floats and overflows at the Cun Kou (radial artery site) with slight fever, this is Zhu Qi Bing (Zhu Qi Disease, often referring to infectious or chronic consumptive conditions). If coughing and high fever are added, with symptoms fluctuating between severe and mild, it is difficult to treat. Conversely, treatment without severe symptoms leads to easy recovery; absence of cough makes it easier to cure.
When a patient's Five Zang organs have exhausted their essence, Shen Ming (Spirit-Mind) cannot reside within, and the voice is hoarse, death occurs.
When a patient grasps at clothing seams and speaks deliriously, it is incurable.
When a patient's Yin and Yang Qi are both exhausted, clutching at empty air and speaking deliriously, death occurs.

If a patient has a yellow face and blue-green eyes, they will certainly die in nine days; this is called Luan Jing (Disordered Meridians).

Even with heavenly rescue, life cannot be restored.
If a patient has a red face and white eyes, they will die in ten days. Worry, anger, and excessive thinking deplete Heart Qi internally; if the complexion appears falsely good, prepare coffins urgently.

Blue-green should resemble the luster of dark jade, not the dullness of indigo.
Red should resemble vermilion wrapped in silk, not the dullness of hematite.
White should resemble goose feathers, not the starkness of salt.
Black should resemble layered lacquer, not the dryness of charcoal.
Yellow should resemble realgar wrapped in gauze, not the dullness of yellow earth.
Regarding eye color: Red indicates Heart disease, White indicates Lung disease, Black indicates Kidney disease, Yellow indicates Spleen disease, and Blue-green indicates Liver disease. If yellow is indescribable, the disease is in the chest center.
In diagnosing eye diseases: Red veins moving from top to bottom indicate Tai Yang Bing (Tai Yang Disease); from bottom to top indicate Yang Ming Bing (Yang Ming Disease); from outside to inside indicate Shao Yang Bing (Shao Yang Disease). In diagnosing cold-heat Luoli (scrofula), if there are red veins in the eyes extending from top to bottom to the pupil, seeing one vein means death in one year; one and a half veins, death in one and a half years; two veins, death in two years; two and a half veins, death in two and a half years; three veins, death in three years.
In diagnosing toothache from dental caries, pressing the Yang Ming pulse: if there is an excess pulse, heat is localized—right side heat on the right, left side heat on the left, upper heat above, lower heat below.
In diagnosing blood-related pulses: many red indicates much heat; many blue-green indicates much pain; many black indicates chronic Bi syndrome. If red, black, and blue-green are all present, it indicates alternating chills and fever with body pain. Slight yellow complexion, yellow dental plaque, and yellow nails indicate Huang Dan Bing (Jaundice Disease). Resting quietly, avoiding yellow/red foods, with a small and choppy pulse indicates poor appetite.
