The extraordinary meridians (奇经八脉 Qí Jīng Bā Mài), or eight marvellous meridians, are deep energy reservoirs in Traditional Chinese Medicine. Unlike the twelve principal meridians that connect Zang-Fu organs and circulate regularly, the extraordinary meridians store, regulate and redistribute Qi, Blood, Jing and organic fluids according to needs.
Extraordinary Meridians
奇经八脉
- Store, regulate and redistribute Qi, Blood, Jing and fluids
- Connect the twelve principal meridians between them
- Regulate the great balances of Yin and Yang
- Control growth, reproduction and ageing cycles
- Maintain deep hormonal, emotional and energetic balance
- Serve as energy reservoirs for principal meridians
The extraordinary meridians are like deep lakes that feed the rivers of the plain. When the rivers are full, the lakes fill up. When the rivers are empty, the lakes overflow. They are the hidden treasures, the strategic reserves, the energetic foundations of life.
In Traditional Chinese Medicine
In TCM theory, the extraordinary meridians are eight energetic vessels that complement and regulate the twelve principal meridians. They are not directly associated with Zang-Fu organs, but store and redistribute energy between principal meridians according to the organism’s needs.
The eight extraordinary meridians are:
- Ren Mai (任脉 Rèn Mài, Conception Vessel): principal Yin vessel, circulates on the anterior median line of the body. Nourishes Yin of the entire body, supports reproduction, fertility, gestation, organic fluids, Qi and Blood
- Du Mai (督脉 Dū Mài, Governing Vessel): principal Yang vessel, circulates on the posterior median line of the body. Supports Yang of the entire body, the spine, brain, spinal cord, vitality, will and capacity for recovery
- Chong Mai (冲脉 Chōng Mài, Thoroughfare Vessel): sea of Blood vessel, circulates in the abdomen and chest. Regulates Qi and Blood, supports reproduction, fertility, gestation, menstruation, lactation, growth and development
- Dai Mai (带脉 Dài Mài, Belt Vessel): circulates horizontally around the waist. Maintains abdominal organs in place, regulates Qi and Blood circulation in the lower abdomen, supports reproduction, fertility, gestation, menstruation, lactation and posture
- Yin Wei Mai (阴维脉 Yīn Wéi Mài, Yin Linking Vessel): connects Yin meridians of feet and trunk. Maintains Yin balance, supports sleep, relaxation, digestion, respiration, heart, lungs, liver, spleen, kidneys and emotions
- Yang Wei Mai (阳维脉 Yáng Wéi Mài, Yang Linking Vessel): connects Yang meridians of feet, hands, trunk and head. Maintains Yang balance, supports awakening, activity, mobility, posture, walking, running, dancing, sport, work, creation, defence, immunity and resistance
- Yin Qiao Mai (阴跷脉 Yīn Qiāo Mài, Yin Heel Vessel): circulates on the inner face of legs and trunk. Maintains Yin balance, supports sleep, relaxation, digestion, respiration, heart, lungs, liver, spleen, kidneys, emotions and posture
- Yang Qiao Mai (阳跷脉 Yáng Qiāo Mài, Yang Heel Vessel): circulates on the outer face of legs, back, shoulders, neck and head. Maintains Yang balance, supports awakening, activity, mobility, posture, walking, running, dancing, sport, work, creation, defence, immunity, resistance and coordination
Practical Applications
In Chinese dietary therapy, extraordinary meridians are supported by foods that nourish Yin, tonify Yang, strengthen Jing, Qi and Blood, and regulate the body’s great balances. Recommended foods include dark and black foods (black beans, black sesame seeds, black seaweed, blueberries, blackberries, blackcurrants), red foods (tomatoes, beetroot, strawberries, cherries, raspberries, pomegranate), white and light foods (pears, apples, radishes, turnips, almonds, sesame seeds), yellow and orange foods (carrots, squash, pumpkins, sweet potatoes, maize, yellow peppers), green foods (spinach, broccoli, asparagus, peas, green salads), Yin-nourishing foods (tofu, black beans, black sesame seeds, lotus seeds, goji berries, longan, jujubes, pears, apples, cucumbers, courgettes), Yang-tonifying foods (lamb, beef, chicken, ginger, garlic, cinnamon, clove, leeks, spring onions, sesame seeds, walnuts, almonds), Jing-tonifying foods (bone and marrow broths, lotus seeds, walnuts, pumpkin seeds, sunflower seeds, eggs, fatty fish, lean meats), Qi-nourishing foods (rice, millet, quinoa, buckwheat, sweet potatoes, carrots, beetroot), Blood-nourishing foods (jujubes, goji berries, longan, figs, grapes, beetroot, spinach, chicken liver, eggs, fatty fish), seasonal vegetables, seasonal fruits, aromatic herbs, mushrooms, seaweed, and liquorice, jujube, goji berry, black sesame seed, lotus and ginger infusions.
Lifestyle is crucial to support extraordinary meridians: moderate physical activity that circulates Qi and Blood throughout the body (walking, swimming, yoga, qi gong, tai chi, dance), stress and emotion management that preserves Yin-Yang balance (meditation, deep breathing, relaxation), sufficient sleep that allows extraordinary meridians to regenerate (7 to 9 hours, ideally 10pm-6am), balanced sexuality that does not dissipate Jing, regular and moderate diet that nourishes Yin, Yang, Jing, Qi and Blood, sufficient hydration, protection against external perversities (Cold, Wind, Dampness, Heat, Dryness), and life in harmony with the seasons strengthen extraordinary meridians.

Frequently Asked Questions
What is the difference between principal and extraordinary meridians?
The twelve principal meridians are directly associated with Zang-Fu organs, circulate regularly and connect the body surface to internal organs. They are like rivers that flow constantly. The eight extraordinary meridians are not directly associated with organs, store and redistribute energy between principal meridians according to needs. They are like deep lakes that fill up when rivers are full and overflow when rivers are empty. The principal meridians are the active circulation; the extraordinary meridians are the strategic reserves.
How to strengthen extraordinary meridians?
Extraordinary meridians are strengthened by nourishing Yin (sufficient sleep, rest, Yin-nourishing foods such as tofu, black beans, pears, apples), tonifying Yang (moderate physical activity, Yang-tonifying foods such as lamb, ginger, cinnamon), strengthening Jing (balanced sexuality, bone broths, walnuts, lotus seeds), nourishing Qi (regular meals, Qi-nourishing foods such as rice, millet, sweet potatoes), nourishing Blood (Blood-nourishing foods such as jujubes, goji berries, beetroot, spinach), and protecting against external perversities. The extraordinary meridians are particularly sensitive to chronic stress, insufficient sleep, sexual excess, irregular diet and extreme climates.
Which foods support extraordinary meridians?
Foods that support extraordinary meridians are generally varied, colourful and balanced, that nourish Yin, tonify Yang, strengthen Jing, Qi and Blood. We cite dark and black foods (black beans, black sesame seeds, seaweed, blueberries), red foods (tomatoes, beetroot, strawberries, cherries), white foods (pears, apples, radishes, almonds), yellow foods (carrots, squash, sweet potatoes), green foods (spinach, broccoli, asparagus), Yin-nourishing foods (tofu, lotus seeds, goji berries, pears), Yang-tonifying foods (lamb, beef, chicken, ginger, garlic, cinnamon), Jing-tonifying foods (bone broths, walnuts, pumpkin seeds, eggs), Qi-nourishing foods (rice, millet, quinoa, sweet potatoes) and Blood-nourishing foods (jujubes, goji berries, beetroot, spinach, eggs).
