Deficiency of the Liver and Kidney Yin

Understanding Deficiency of the Liver and Kidney Yin

The tradition describes the Liver and Kidney as sharing a source, with the Kidney supplying the deeper Yin that the Liver draws on. When Kidney Yin declines, Liver Yin follows, so the signs appear together.

The lower back and knees ache and feel weak, and tinnitus is often high-pitched. The eyes are dry and vision may blur, with dizziness when tired.

A low-grade heat appears: night sweats, warmth in the palms and soles, and a red thin dry tongue with little or no coat. The pulse is fine and rapid.

It follows chronic overwork, ageing, prolonged emotional strain, or recovery from a severe or prolonged illness.

Treatment nourishes Liver and Kidney Yin together, with attention to sleep and rest because those are what replenish it.

Signs and symptoms

Key signs

• Lower back and knee soreness or weakness
• Dizziness or tinnitus
• Dry eyes or blurred vision
• Night sweats or heat in the palms and soles

Also seen

• Dry mouth and throat
• Poor memory
• Insomnia
• Scanty dark urine
• Dry skin and hair
• Irritability

Variations

• Painful heels
• Hair loss or early greying
• A feeling of heat in the chest

Timing

• The heat and dryness are worse at night and in the late afternoon.
• It develops slowly over months to years.

Practitioner notes

• The tongue is red and thin with scanty or absent coating and a dry surface.
• The pulse is fine and rapid, and empty at the deep level.
• The distinction from Liver Yang rising is emptiness rather than excess: here the pulse is fine, while Yang rising gives a wiry forceful pulse and marked head symptoms.
• The distinction from Kidney and Lung Yin deficiency is the eye and sinew involvement, which points to the Liver.

Causes

Common causes

• Chronic overwork and depletion
• The natural process of ageing
• Prolonged emotional strain
• Consequences of severe or prolonged illness

How it develops

• It develops slowly from sustained depletion.
• If the Heat becomes prominent, it can progress to empty heat or heat in the Blood.

Diagnosis

Diagnosis rests on the combined Liver and Kidney Yin signs with a red thin dry tongue and fine rapid pulse.

Tongue

• Body: Red, thin and dry.
• Coating: Scanty or absent.
• Note: A greasy coat would point to Dampness instead.

Pulse

Fine, Rapid

Fine and rapid, empty at the deep level.

Observation

• A thin dry appearance
• Flushing over the cheekbones
• Dry eyes

Listening

• A quiet voice
• Reports of high-pitched tinnitus

Palpation

• Abdomen: Soft and empty below the navel.
• Channels: KI-3 and LR-3 may feel empty; the lower back is tender to light pressure.

Questions that separate it from look-alikes

• How are the lower back and knees?
• Any tinnitus, dry eyes or blurred vision?
• Any night sweats or heat in the palms and soles?
• How is sleep and overwork?

Treatment

Principles

• Nourish Liver and Kidney Yin
• Brighten the eyes and settle tinnitus
• Clear the low-grade heat gently
• Protect sleep and rest

Herbs

Formulas

• Yi Guan Jian - The reference formula for Liver and Kidney Yin deficiency with dryness and rib discomfort.
• Qi Ju Di Huang Wan - For Yin deficiency with dry eyes and blurred vision.
• Liu Wei Di Huang Wan - The foundational Kidney Yin tonic, used where the picture is milder.

Acupoints

• Taixi KI-3 - The Kidney source point, used for lower back weakness and Yin deficiency.
• Taichong LR-3 - The Liver source point, used for dizziness and dry eyes.
• Sanyinjiao SP-6 - Nourishes the three Yin channels.
• Ganshu BL-18 - The Liver back-shu point, supporting Liver Yin and Blood.

Personalising the plan

• If the eyes dominate, eye-nourishing herbs are increased.
• If heat dominates, gentle clearing herbs are added.
• If the lower back dominates, Kidney tonics are increased.
• If sleep is poor, spirit-calming herbs are added.

Self-care

Diet

• Avoid spicy, fried and drying food
• Reduce alcohol and coffee

Lifestyle

• Early and consistent sleep
• Reduce overwork and sexual excess
• Rest the eyes from screens
• Gentle exercise rather than exhaustion

Qigong and movement

• Slow restorative practice with an emphasis on softness and the lower body.

How it differs from look-alikes

Patterns that can be mistaken for deficiency of the liver and kidney yin, and the contrast that separates them.

Where it appears

Skin conditions in which this pattern is commonly seen.

Safety and when to get help

For anything severe, sudden or spreading quickly, read when a skin problem needs urgent care.

This page describes a TCM pattern, not a diagnosis, and a pattern can accompany more than one skin condition. Get urgent medical help for a rash with fever, confusion or feeling very unwell; skin that is blistering, peeling or spreading quickly; swelling of the face, lips or throat, or difficulty breathing; or a lesion with increasing pain, warmth, red streaks or pus. For anything persistent, severe or changing, have it assessed by a clinician before treating it yourself.

Read the skin condition pages for the red flags that belong to a specific presentation.

Urgent-sign guidance is based on standard sources: NHS anaphylaxis, NHS cellulitis, NHS Stevens-Johnson syndrome, NHS melanoma.

Evidence note

No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit.
