When pressed heavily, the pulse feels as if it is about to cease. It seems to be there and not there, extremely minute. The Minute pulse (Wei Mai) belongs to the category of Yin and Yang deficiency syndromes. (Because both Yin and Yang are deficient, the pulse presents a seemingly present yet absent appearance, hence named "Minute".) It is accompanied by aversion to cold, fever, and profuse sweating. (Yang deficiency generates cold; Yin deficiency generates heat. If Yang fails to secure the exterior and Yin fails to guard the interior, excessive sweating occurs.) A Minute pulse at the Cun position indicates epistaxis, palpitations, and wheezing. A Minute pulse at the Guan position indicates middle jiao coldness leading to stiffness and spasm. (Deficiency of Qi and Blood leads to middle jiao coldness; cold causes constriction in the epigastric region, resulting in tightness and lack of relaxation.) A Minute pulse at the Chi position indicates cold extremities (Jue Ni), signifying damage to Yuan Yang. (Yang fire originates from Yin essence; when Yin essence is deficient, Yang fire becomes weak. Weak Yang fire leads to cold hands and feet, forming Jue syndrome. When Yin and Yang fail to interact, Qi rushes upward, causing rebellion.) In women, it indicates depletion due to metrorrhagia and leukorrhea.
The pulse distinguished by heavy pressure is called Deep (Chen). It is only felt upon heavy pressing. Distinguished further from Deep is Hidden (Fu), which is only felt when pressing down to the bone. Regarding these two pulses...
Deep pulse (referred to as Stone pulse or Ying pulse in the *Nei Jing*.) Firm pulse (Lao Mai): The Firm pulse is a type of Deep pulse, characterized by being long, large, wiry, and forceful. It indicates Cold and Pain, sharing similarities with the Deep pulse; it is attached here for reference. Pulses felt only upon pressing are Deep. (The Deep pulse corresponds to Winter. Its appearance in Spring, Summer, or Autumn indicates disease. However, in Winter, if the Qi arrives deep and striking, it is a normal pulse. If it arrives hard like a bouncing stone, this is termed Excess (Tai Guo); if it departs rapidly, this is termed Deficiency (Bu Ji), both indicating disease.) Deep pulse at the Cun position indicates chest and hypochondriac pain, caused by fluid retention in the diaphragm. If found at the Guan and Chi positions, it indicates abdominal, back, and lower back pain. (Deep pulse indicates Yin syndromes; excess Yin attacks vital Qi. Therefore, Deep pulses in all three positions indicate pain, suitable for warming treatment; if fluid retention is present, draining treatment is suitable.) Deep and slow indicates Cold-Damp; Deep and rapid indicates Heat; Deep and slippery indicates Phlegm and Food Stagnation. A Deep pulse that is forceless clearly indicates severe Qi deficiency. (A Deep pulse with force indicates pathogenic Excess, thus indicating Cold and accumulation; a Deep pulse without force indicates Qi deficiency.) Cui Zixu stated in *Si Yan Ju Yao*: Deep and Firm pulses indicate entrenched Cold. Deep and Real pulses indicate extreme Heat. Upon examination: The Firm pulse is Deep, long, large, and forceful upon pressing; the Real pulse is also Deep, lying flat, long, large, and forceful. Both are Deep, long, large, and forceful; how can one distinguish between entrenched Cold and extreme Heat?
