Key Concepts of Weak and Strong Pulses in TCM Diagnosis – Essential for Exams and Practitioners

Weak Pulse Category

1. From the Outline

Weak Pulse – should indicate lack of strength

Weak Pulse – when lifted, it is weak; when pressed, it feels empty—indicating deficiency of both Qi and Blood

Thin Pulse – pulse is thin like a thread, should indicate obvious signs—indicating deficiency of both Qi and Blood, and dampness

Minute Pulse – extremely thin and soft, almost imperceptible—indicating various deficiency syndromes, and sudden loss of Yang Qi

Intermittent Pulse – slow and stops intermittently, this has a fixed pattern—indicating weak organ Qi, pain, fright, or trauma

Short Pulse – both ends are short, not reaching the normal position—strong indicates Qi stagnation, weak indicates Qi deficiency

2. Mnemonic

Weak, Thin, Minute, Intermittent, Short
