Excess-Heat

Understanding Excess-Heat

The tradition distinguishes excess Heat from empty Heat by fullness. Excess heat is strong and forceful: the pulse pushes back, the face is red, and the person wants cold. Empty heat is weak and empty, coming from deficiency.

The heat is high and constant, with intense thirst that only cold drinks satisfy. The face is red, the person is restless, and the pulse is rapid and forceful.

The tongue is red, possibly with raised red points, with a thick dry yellow coat. The urine is dark and scanty and the stools may be dry.

It arises from external Heat or Summer Heat, from Cold that has transformed into Heat inside the body, from intense emotion, or from overwork and sleep deprivation.

Treatment clears and drains the Heat. Strong bitter-cold herbs are used, and they are stopped once the Heat is cleared because prolonged use damages the digestion.

Signs and symptoms

Key signs

• High fever or strong sensation of body heat
• Intense thirst for cold drinks
• Red face
• Rapid and forceful pulse

Also seen

• Restlessness and irritability
• Dark scanty urine
• Dry stools or constipation
• Sweating that does not relieve the heat
• A bitter taste
• Red eyes

Variations

• Mouth ulcers
• Nosebleeds
• A throbbing headache

Timing

• It is acute and constant rather than intermittent.
• It worsens in the afternoon and in heat.

Practitioner notes

• The tongue is red, possibly with raised red points, with a thick dry yellow coat.
• The pulse is rapid and forceful: the force is what separates excess from empty heat.
• The distinction from empty heat is fullness: empty heat has a fine rapid pulse and a dry tongue with no coat.
• The distinction from Bright Yang Stomach Heat is specificity: that pattern localises to the Stomach with the four classic signs.

Causes

Common causes

• Invasion by external Heat or Summer Heat
• Cold pathogens transforming into Heat inside the body
• Prolonged anger, frustration or stress
• Overwork and sleep deprivation

How it develops

• It develops acutely or from an unresolved earlier pattern.
• If untreated, it can damage fluids and Yin, becoming a mixed deficiency and excess picture.

Diagnosis

Diagnosis rests on strong heat signs with a forceful pulse and a thick yellow coat.

Tongue

• Body: Red, possibly with raised red points.
• Coating: Thick, dry and yellow.
• Note: A tongue with no coat would suggest empty heat instead.

Pulse

Rapid, Forceful, Slippery

Force is the key: it shows the heat is excess.

Observation

• Red face
• Restlessness
• Sweating

Listening

• A loud or sharp voice

Palpation

• Abdomen: May feel hot; fullness if the bowels are affected.
• Channels: The skin is hot; DU-14 and LI-11 may feel hot.

Questions that separate it from look-alikes

• Is there thirst, and for cold drinks?
• How high is the fever?
• Any constipation or dark urine?
• How much alcohol, spicy food and stress lately?

Treatment

Principles

• Clear Heat
• Drain Fire where it is localised
• Protect the fluids
• Use strong clearing briefly rather than long term

Herbs

Formulas

• Bai Hu Tang - The reference formula for excess Heat with fever, sweating and thirst.
• Huang Lian Jie Du Tang - For Heat with toxin, draining Fire from the whole body.
• Qing Ying Tang - For Heat that has entered the nutritive level, with fever at night.
• Long Dan Xie Gan Tang - For excess Heat localised in the Liver and Gallbladder.
• Liang Ge San - For Heat in the upper body with sore throat and mouth symptoms.

Acupoints

• LI-4 (Hegu) - Clears Heat from the upper body.
• DU-14 (Dazhui) - Clears Heat from the whole body, used in febrile conditions.
• ST-44 (Neiting) - Clears Heat from the Stomach and the face.
• SP-10 (Xuehai) - Cools the Blood, used where Heat has entered it.
• LR-2 (Xingjian) - Drains Liver Fire, used for red eyes and irritability.

Personalising the plan

• If the bowels are constipated, draining herbs are added.
• If the fluids are damaged, moistening herbs are increased.
• If the Heat is localised, herbs specific to that area are used.
• If the person is depleted, the strong clearing is reduced and support added.

Self-care

Diet

• Cooling food and drink: water, mung bean, watermelon, cucumber
• Avoid spicy, fried and greasy food
• Stop alcohol while the heat persists

Lifestyle

• Rest in a cool environment
• Light clothing
• Sleep early
• Reduce stress and anger

Qigong and movement

• Gentle practice in a cool setting, avoiding exertion that raises body heat.

How it differs from look-alikes

Patterns that can be mistaken for excess-heat, 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. Where skin-specific research does exist it is linked above.
