Yang Deficiency

Yang Deficiency represents a fundamental insufficiency of yang qi, characterized by hypofunction of the body's warming, transforming, and qi-promoting activities. The pathomechanism involves depletion of primordial yang leading to failure of qi transformation, water metabolism dysfunction, and systemic hypothermic manifestations. This pattern forms the constitutional foundation for numerous chronic degenerative conditions and requires sustained tonification protocols.

Clinical Presentation

Aversion to cold, cold limbs, preference for warmth
Fatigue, lethargy, lack of motivation
Pale complexion, withdrawn spirit
Poor appetite, loose stools, undigested food particles
Frequent urination, clear copious urine, nocturia
Lower back and knee soreness and weakness
Decreased libido, impotence, infertility
Edema, particularly in lower limbs
Tongue: pale, swollen, wet, thick white coating
Pulse: deep, slow, weak, or deep and thready

Pattern Differentiation

vs. Qi Deficiency

Yang Deficiency includes prominent cold signs (aversion to cold, cold limbs, preference for warmth) and water metabolism dysfunction (edema, clear copious urine). Qi Deficiency lacks these thermal and fluid metabolism disturbances, presenting primarily with fatigue and organ-specific hypofunction without systemic cold manifestations.

vs. Yin Deficiency

Yang Deficiency presents with cold signs, fluid retention, and slow metabolism. Yin Deficiency shows heat signs (five-palm heat, night sweats, malar flush), fluid depletion manifestations (dry mouth, scanty dark urine), and hypermetabolic tendencies. Pulse quality differs: Yang Deficiency shows slow, deep pulses versus rapid, thready pulses in Yin Deficiency.

vs. Kidney Yang Deficiency

Kidney Yang Deficiency represents a specific organ manifestation of constitutional Yang Deficiency, emphasizing reproductive dysfunction, lumbar weakness, and dawn diarrhea. Constitutional Yang Deficiency affects multiple organ systems simultaneously with broader metabolic and thermal regulatory dysfunction extending beyond kidney-specific symptomatology.

Treatment Principle

Warm and supplement yang qi, strengthen the fires of mingmen, promote qi transformation, and regulate water metabolism.

Frequently Asked Questions

Initial stages show deep, slow pulses with reasonable strength. Progressive depletion manifests as increasingly weak and thready qualities. Terminal yang collapse presents as extremely deep, minute, or intermittent pulses indicating imminent yang qi exhaustion requiring immediate intervention.

Constitutional Yang Deficiency shows lifelong cold intolerance, chronic fatigue from early age, and family history patterns. Acquired depletion develops after specific triggers (chronic illness, overwork, excessive cold exposure) with clear onset timing and more rapid progression of symptoms.

Kidney yang deficiency usually appears first, as kidney stores constitutional yang qi. Spleen yang follows, manifesting as digestive dysfunction and dampness accumulation. Heart yang deficiency represents advanced constitutional depletion affecting circulation and shen stability.

Moxibustion takes priority when digestive function is severely compromised (preventing herbal absorption), in acute yang collapse states, or when patient constitution cannot tolerate warming herbs. Direct moxa to key points like mingmen, guanyuan, and zusanli provides immediate yang support while rebuilding digestive capacity.
