Yang Deficiency (阳虚 Yáng Xū) is a fundamental syndrome in Traditional Chinese Medicine, characterised by exhaustion of the heat and transformation principle that manifests as persistent cold intolerance, internal cold, slow digestion and lowered functional activity.
Yang Deficiency
阳虚
- Manifests as cold intolerance, cold extremities and slow digestion
- Affects Kidney, Spleen, Heart and circulation
- Causes loose stools, clear urine and deep fatigue
- Requires hot foods and cooking methods
- Can evolve towards internal Cold if untreated
Yang Deficiency represents exhaustion of vital fire. Kidney Yang is the root of all body Yang; when it weakens, heat declines, transformation slows and Cold settles in organs and tissues.
In Traditional Chinese Medicine
In TCM theory, Yang Deficiency occurs when the heat, activity and transformation principle is weakened. Main causes are prolonged Qi exhaustion evolving towards Yang, chronic cold exposure, cold and raw diet, ageing, excessive sexual activity, or a naturally cold constitution from birth.
Yang Deficiency can concern different organs:
- Kidney Yang Deficiency: deep cold intolerance, cold lower back pain, decreased libido, clear and abundant urine, oedema
- Spleen Yang Deficiency: loose or morning diarrhoea stools, loss of appetite, cold bloating, fatigue after meals
- Heart Yang Deficiency: palpitations, oppressed chest, bluish complexion, thoracic cold intolerance
- Spleen-Pancreas Yang Deficiency: very loose stools, oedema, weight loss, muscle loss
Practical Applications
In Chinese dietary therapy, Yang Deficiency is treated by foods of hot or warm nature, pungent or sweet flavour, rich in energy and consumed hot. Foods that warm Yang include ginger, garlic, leeks, cooked onions, cinnamon, clove, lamb, beef, chicken, walnuts, dry-roasted seeds, dates and boiling soups.
Cooking method is crucial in Yang Deficiency treatment: long slow cooking, stews, boiling soups, roasts and hot consumed foods warm Yang. Raw, cold, refrigerated or cold consumed foods aggravate Yang Deficiency.
Concrete Examples
A patient presenting with Kidney Yang Deficiency may experience deep cold intolerance even in summer, chronic lower back pain aggravated by cold, very decreased libido, clear and abundant urine especially at night, evening ankle oedema and deep fatigue. The dietary protocol will include Yang warming foods such as lamb stewed with leeks and ginger, rice porridge with dates and cinnamon, dry-roasted walnuts as snacks and hot clove infusions.
A patient presenting with Spleen Yang Deficiency may experience loose or morning diarrhoea (upon waking or after breakfast), loss of appetite, cold sensation in abdomen, cold bloating, fatigue after meals and pale swollen tongue with thick white coating. The dietary protocol will include foods that warm Spleen Yang such as rice porridge with ginger and dates cooked long, chicken stewed with carrots and onions, roasted sweet potatoes and liquorice and cinnamon infusions.
Frequently Asked Questions
What is the difference between Yang Deficiency and perverse Cold?
Yang Deficiency is internal exhaustion of the heat principle, manifesting as chronic cold and lowered functional activity. Perverse Cold (external Cold) is a pathogenic factor that penetrates the body from outside, provoking acute cold, chills and pain. Yang Deficiency predisposes to perverse Cold penetration, and chronic perverse Cold can weaken Yang.
How to recognise Yang Deficiency?
Classic signs of Yang Deficiency include persistent cold intolerance (even in summer or in a heated room), cold extremities (hands, feet, nose), loose or morning diarrhoea stools, clear and abundant urine, pallor or bluish complexion, deep fatigue, pale swollen tongue with white coating, and deep weak pulse. The patient seeks heat and feels better in sunshine or near a heat source.
Which foods warm Yang?
Yang warming foods are generally of hot or warm nature, pungent or aromatic, and consumed hot. Fresh ginger, garlic, leeks, cooked onions, cinnamon, clove, cumin, lamb, beef, chicken, dates, walnuts, dry-roasted seeds, boiling root vegetable soups and hot spice infusions are cited.
