The Triple Burner (三焦 Sān Jiāo) is one of the most fascinating and complex concepts in Traditional Chinese Medicine. Unlike the other Zang-Fu organs, it has no identifiable anatomical form - it is an energetic function, an invisible interface that regulates the circulation of water and fire throughout the organism. Understanding the Triple Burner meridians means understanding how the body distributes its heat, manages its fluids and maintains its thermal balance.
The Triple Burner: An Organ Without Form
The Energetic Function of the San Jiao
The Huangdi Neijing (黄帝内经) defines the Triple Burner as the “official in charge of irrigation and water regulation”. It acts as an energetic distribution system that:1. Distributes original fire (Yuán Qì 元气) from the Kidneys towards the whole organism 2. Manages fluid circulation (Jin-Yè 津液) in three distinct zones 3. Regulates body temperature by coordinating exchanges between internal organs and skin/muscles 4. Facilitates digestive transformations by linking the Three Burners (上焦 Shàng Jiāo, 中焦 Zhōng Jiāo, 下焦 Xià Jiāo)
The Three Burners of the Triple Burner
Energetic Body Distribution
| Burner | Zone | Function | Dominant Energy | Typical Disorders |
|---|---|---|---|---|
| 上焦 Shàng Jiāo (Upper Burner) | Chest, heart, lungs | Dispersion of Qi and fluids upwards | Pure Yang, diffusion | Cough, asthma, chest oppression, abnormal sweating |
| 中焦 Zhōng Jiāo (Middle Burner) | Abdomen, stomach, spleen | Transformation of food into Qi and Blood | Digestive heat | Slow digestion, bloating, nausea, bitter taste |
| 下焦 Xià Jiāo (Lower Burner) | Pelvis, kidneys, bladder | Elimination of impurities and essence storage | Deep Yin, filtration | Urinary retention, diarrhoea, lumbar pain, gynaecological disorders |
The Theory of “San Jiao Dysfunction”
When the Triple Burner no longer functions correctly:Upper Burner Dysfunction → Qi no longer rises: mental fatigue, chronic cough, headaches by Qi Deficiency
Middle Burner Dysfunction → Dampness accumulates: heaviness after meals, phlegm, greasy skin
Lower Burner Dysfunction → Waters stagnate: heavy legs, urinary disorders, infertility
The Meridians of the Triple Burner
Principal Triple Burner Meridian (三焦经 Sān Jiāo Jīng)
Type: Yang Meridian (阳经)
Course: 23 points, beginning at ear → ends at middle finger tip
Peak flow hour: 21h-23h (亥时 Hài Shí)
Paired organ: Pericardium (心包 Xīn Bāo)
Yang Meridian Trajectory
- Departure: External auricle (point 耳门 TB21)
- Ascent: Temple, eyebrow arch (point 丝竹空 TB23)
- Descent: Neck, shoulder (points 肩髎 TB14, 天髎 TB15)
- Arm: Posterior face of arm and forearm
- Hands: Space between ring finger and middle finger (point 液门 TB2) → middle finger tip (point 关冲 TB23)
Essential Points of the Yang Meridian
| Point | Name | Location | Main Indications | Energetic Nature |
|---|---|---|---|---|
| TB5 外关 (Wài Guān) | Outer Passage | 2 inches above wrist, back of hand | Fevers, temporal migraines, deafness, facial paralysis | Master Point of Yang Wei (阳维), opens outwards |
| TB6 支沟 (Zhī Gōu) | Branch Ditch | 3 inches above wrist, back of hand | Constipation, vomiting, chest distension, intermittent fevers | Key point to mobilise San Jiao Qi |
| TB10 天井 (Tiān Jǐng) | Celestial Well | Posterior elbow hollow, extension | Lymphatic drainage, goitre, cervical pain, psychosis | Fluid gathering point |
| TB15 天髎 (Tiān Liáo) | Celestial Bone | Below spinous process C7, above scapula | Cervical stiffness, occipital migraines, cough, oppression | Crossing point with Yang Wei and Small Intestine |
| TB23 丝竹空 (Sī Zhú Kōng) | Silk Bamboo Empty | External eyebrow arch | Fronto-temporal headaches, facial paralysis, eye pain, nosebleed | Major termination point for the whole head |
Communicating Meridian of the Triple Burner (手少阳经别)
Type: Yin collateral meridian (经别)
Course: 23 points, beginning at armpit → heart → neck exit → ear → ends at eye corner
This internal branch links the San Jiao to the Heart and the eye, explaining why Triple Burner disorders can manifest through visual or cardiac problems.#### Key Points of the Yin Meridian
| Point | Name | Location | Specific Function |
|---|---|---|---|
| TB17 翳风 (Yì Fēng) | Wind Protector | Mastoid hollow, behind ear | Deafness, tinnitus, facial paralysis, otitis |
| TB20 角孙 (Jiǎo Sūn) | Horn Grandson | Front of auricle, temporal hairline | Toothache, gum pain, gum recession |
| TB21 耳门 (Ěr Mén) | Ear Gate | Before upper incisure of pavilion | Deafness, tinnitus, otitis, blocked jaw |
Clinical Applications of Triple Burner Points
Headaches and Head Disorders
Points TB5, TB15 and especially TB23 are the TCM references for temporal-type headaches and fronto-temporal headaches. The Triple Burner manages Qi circulation in the Shao-Yang zone (少阳), which corresponds precisely to the temples and lateral zones of the head.Protocol: Bilateral stimulation of TB23 (丝竹空) for pulsatile temporal headaches accompanied by nausea Energetic explanation: Liver Yang rises through the Shao-Yang meridian (Gall Bladder and Triple Burner). TB23 makes this excess Yang descend.
Digestive Disorders and Nausea
Point TB6 支沟 is the Master point recognised for 2,000 years for any nausea, vomiting or abdominal distension linked to Middle Burner imbalance.Protocol: Firm pressure 2-3 minutes on bilateral TB6, associated with stimulation of Stomach 36 (ST36) Effect: Mobilises stagnant Qi of the Middle Burner, makes the rebellious Qi descend that causes nausea
Fevers and Fire Syndromes
TB5 外关 is called “Outer Passage” because it expels Wind-Heat (风热 Fēng Rè) and opens the Yang pathways towards the surface.Protocol: Needle or strong pressure on TB5 + Large Intestine 4 (LI4) + Lung 7 (LU7) Indications: High fevers, shivering, dry cough, inflammatory sore throat
Deafness and ENT Disorders
Points TB17, TB21 and TB5 form the classic trio for any energetic-origin auditory disorder: sudden deafness, tinnitus, chronic otitis.Protocol: Moxibustion on TB17 for deafness by Yang Deficiency + stimulation TB5 Principle: The Triple Burner irrigates the “nine orifices” (ears included) according to the Ling Shu
Triple Burner Dietetics
Foods that Facilitate the San Jiao
According to Chinese dietetic principles, the Triple Burner is nourished by foods that:1. Drain Dampness without drying out (gherkin, shallot, dandelion) 2. Regulate heat without extinguishing digestive fire (cucumber, bitter melon, lettuce) 3. Facilitate fluid circulation (black radish, lotus, barley)
| Condition | Recommended Foods | Foods to Avoid |
|---|---|---|
| Blocked Upper Burner (chest oppression, cough) | Pear, chrysanthemum (Jú Huā), wheat, radish | Heavy foods, fried, fatty cheeses |
| Congested Middle Burner (nausea, bloating) | Cooked ginger, cardamom, fennel, citrus | Ice cream, raw dairy products, excess meat |
| Stagnant Lower Burner (oedema, retention) | Azuki beans, dandelion, squash, sesame | Excess salt, alcohol, refined sugar |

Key Points to Remember
- The Triple Burner has no anatomical structure but an essential function: distributing heat and fluids in the three bodily burners
- Its two meridians (Yang principal and Yin communicating) total 46 points distributed from ear to hands, and from armpit to eye
- Points TB5, TB6, TB10, TB23 are the most clinically used for headaches, nausea, fevers and ENT disorders
- In TCM dietetics, favour draining but non-drying foods and avoid excesses that congest the three burners
- The Triple Burner hour (21h-23h) is propitious for rest to optimise its nocturnal regulation function
FAQ on Triple Burner Meridians
Why does the Triple Burner have no anatomical structure?
The San Jiao is an energetic function rather than a material organ. It represents the interface between all organs for fluid and heat circulation - a concept that does not exist in Western anatomy but has correspondences with the lymphatic system, thermoregulation and tissue fluid circulation.
What is the difference between Triple Burner and Pericardium?
In the Zang-Fu system, the Pericardium (心包 Xīn Bāo) is considered the “minister of the heart” (Yin organ), whilst the Triple Burner (三焦 Sān Jiāo) is its paired Yang organ. They form a functional pair: the Pericardium protects the Heart, the San Jiao regulates the energetic circulation that feeds this protection.
How to stimulate Triple Burner points at home?
Accessible points such as TB5 (2 inches above wrist, back of hand) and TB23 (external eyebrow corner) can be stimulated by: firm pressure 2-3 minutes, circular massage, or application of warm essential oils (ginger, cinnamon). For temporal headaches, TB23 is particularly effective.
What are the symptoms of an imbalanced Triple Burner?
Signs vary according to the affected burner: Upper Burner → chronic cough, chest oppression, abnormal sweating; Middle Burner → slow digestion, nausea, bitter taste; Lower Burner → urinary disorders, heavy legs, gynaecological disorders. The common characteristic is thermal dysregulation: alternation of heat and chilliness.
