Reclaiming Shen: How Acupuncture Treats the Shen(Spirit)

The Role of Shen in Chinese Medicine

Shen in Chinese medicine can be understood in both a broad and a narrow sense. In its broad sense, Shen refers to the outward manifestations of life activity, such as the brightness of the eyes and the complexion. In its narrow sense, Shen specifically denotes human mental awareness and cognitive activity.

Within the grand theoretical system of Chinese medicine, mental and emotional health is not regarded as a psychological phenomenon isolated from the body, but rather as a higher-level manifestation of the physiological functions of the Zang-fu organs. In modern biomedicine, psychiatry and neurology are often treated as independent clinical disciplines. By contrast, in the traditional Chinese medical perspective, body and mind constitute an inseparable unity. Human mental activity is not merely the electrochemical activity of the cerebral cortex, but an outward projection of the flourishing or decline of the essential qi of the five zang and six fu organs. The theory of the Five Spirits provides the key to understanding this mechanism: the Liver stores the Hun, the Heart stores the Shen, the Spleen stores the Yi, the Lung stores the Po, and the Kidney stores the Zhi. Among these Five Spirits, the relationship between Shen and Hun is particularly special and crucial. Shen is the commander of consciousness, while Hun is its assistant: the former governs rational thinking during wakefulness, while the latter governs subconscious emotional flow and nocturnal dreaming. Whether these two cooperate smoothly directly determines an individual’s decisiveness during the day and the quality of sleep at night.

The Sovereign Role of the Heart

The Heart is regarded as the sovereign official and is said to store Shen. Shen is the supreme commander of all mental activities, governing the other four spirits—Hun, Po, Yi, and Zhi. If the Heart-Shen loses its governance, this not only leads to disorders of the Heart itself but also causes dysfunction of other organs, just as chaos arises in the state when the sovereign is incompetent. The material basis of Shen is Blood. The Heart governs the blood vessels; when the vessels are full, Shen has a place to reside. The state of Shen can be observed through the complexion and the tongue. When Heart Blood is abundant, the mind is clear and the complexion is rosy; when Heart Blood is deficient, Shen lacks support, leading to palpitations, poor memory, and insomnia.

The Liver Stores the Hun: Strategic Planning and Free Flow

Hun resides in the Liver. If Shen is likened to the emperor who issues commands, then Hun is comparable to the strategist or general who formulates plans and evaluates situations.

The Mental Hierarchy of Hun

Hun represents a level of mental activity one dimension below Shen. This does not diminish its importance. Hun is responsible for evaluation and judgement and is the source of reason and wisdom. It assists Shen in cognitive processing, particularly in matters involving long-term planning and subconscious intuition.

Hun is anchored in Liver Blood. The Liver stores Blood, and Blood houses Hun. As the body’s blood reservoir, the Liver provides Hun with a place of residence. If Liver Blood is deficient, Hun loses its anchor and drifts like a kite with a broken string, leading to symptoms such as excessive dreaming, sleepwalking, and fright.

The Liver governs the free coursing and discharge of qi, regulating the smooth flow of qi throughout the body. The flexibility of Hun depends on the movement of qi. When qi flows freely, mental activity is expansive and emotions are stable; when qi becomes constrained, depression and irritability arise.

Treating the Spirit with Five Elements

In the classical acupuncture tradition, treatment extends far beyond addressing physical symptoms to encompass the spirit—often referred to as Shen, Hun, Yi, Po, and Zhi—reflecting the profound interconnection between body, mind, and spirit that lies at the heart of classical Chinese medicine. The Five Element theory (Wood, Fire, Earth, Metal, and Water) provides a holistic framework in which each element corresponds not only to physical structures such as zang-fu organs, seasons, and bodily functions, but also to emotional and spiritual qualities. For example, Wood is associated with initiative and planning, Fire with joy and connection, Earth with stability and nourishment, Metal with clarity and structure, and Water with will and wisdom.

In Chinese medicine, health is understood as the harmonious flow and balance of these five elements. When the energy of a particular element becomes imbalanced, this disturbance manifests not only as physical disharmony but also as emotional and spiritual disruption. Practitioners therefore seek to identify the causative element underlying a person’s imbalance and employ carefully selected acupuncture points and needling strategies to restore equilibrium at the physical, emotional, and spiritual levels. This approach places the person’s spirit (Shen) at the centre of diagnosis and treatment, recognising that restoring spiritual balance enables the body and mind to regain their own equilibrium, fostering deeper healing and well-being. Traditional acupuncture similarly emphasises the whole person, using comprehensive diagnostic methods—including observation, pulse and abdominal diagnosis, listening to the voice, and assessing emotional state—to identify the root pattern of disharmony and guide treatment that integrates physical and spiritual renewal.

How to Calm the Spirit (Shen) with Acupuncture

Traditional Chinese medicine holds that “the Heart governs the Shen”. The Heart stores mental consciousness, while the Liver governs the free flow of emotions. Excessive stress can lead to Liver qi stagnation and inadequate nourishment of the Heart-Shen, resulting in restlessness of the mind, anxiety, and depression. Acupuncture treatment of emotional and mental disorders focuses on harmonising yin and yang and balancing the zang-fu organs, allowing the disturbed Shen to return to a state of calm. Clinically, treatment principles often emphasise calming the Heart and settling the Shen, as well as soothing the Liver and relieving constraint. Commonly selected points include Baihui, Sishencong, Yintang, and Neiguan to clear the mind, open the orifices, and calm the spirit, with additional points such as Qimen and Taichong to soothe the Liver, relieve stagnation, and nourish the Heart while regulating the Shen.

Scalp acupuncture is a modern technique that integrates traditional needling with cerebral localisation, regulating neural activity by inserting needles into specific scalp regions corresponding to functional areas of the brain.

Auricular acupuncture makes use of reflex zones on the auricle corresponding to the zang-fu organs to regulate bodily function and calm the spirit. Clinically, intradermal needles or ear seeds are commonly applied to auricular points. In the treatment of anxiety and depression, points corresponding to the Heart, Liver, and Spleen are often selected to regulate the organs and settle the Shen. Among these, the Shenmen point located in the triangular fossa of the auricle is regarded as a natural tranquilliser. It has a pronounced calming effect, alleviating agitation and improving sleep, and is a key point in the treatment of anxiety and insomnia. Stimulation of auricular Shenmen can regulate autonomic nervous system activity, reducing excessive sympathetic excitation and promoting relaxation of both body and mind. Owing to its simplicity, non-invasive nature, and safety, auricular acupuncture is frequently used as an adjunctive self-regulation method for patients with emotional dysregulation.

Modern research has reinterpreted the calming effects of acupuncture from a neurophysiological perspective, often referred to as “neuro-acupuncture” or neuromodulatory acupuncture. Numerous experimental studies demonstrate that acupuncture influences the central nervous and endocrine systems by stimulating peripheral nerves, such as the vagus nerve, thereby regulating emotional responses. For example, acupuncture can promote the release of neurotransmitters associated with positive mood, such as serotonin and dopamine, while reducing levels of stress hormones such as cortisol, stabilising emotions at a physiological level. Acupuncture also modulates autonomic nervous system function, calming excessive sympathetic activity and enhancing parasympathetic tone, thereby alleviating tension and restoring mind–body balance. These modern findings provide a scientific explanation for the traditional concept of “regulating the Shen”: classical points such as Neiguan and Shenmen calm the Heart and stabilise the will precisely because they influence vagal cardiac reflexes and the limbic system through neural pathways, producing anxiolytic and calming effects.

The Back Shu Points

In Chinese medicine, the Bladder channel on the back is divided into two parallel lines: The first lateral line (1.5 cun lateral to the spine) contains the Back Shu points, such as Feishu, Xinshu, and Ganshu, which primarily treat the physiological functions of the zang-fu organs. The second lateral line (3 cun lateral to the spine) contains points such as Pohu, Shentang, and Hunmen, many of which are named after Shen, Hun, Po, Yi, and Zhi, and are particularly focused on mental and emotional conditions.

The reason the Bladder channel on the back can treat emotional disorders such as anxiety, depression, and insomnia lies in the anatomical structures underlying these two lines, which are areas of dense concentration of the autonomic nervous system—responsible for emotional physiological responses—and fascial receptors, which store somatised emotional memory. Anatomically, these two lines correspond to different branches of the dorsal ramus of the spinal nerve. The first lateral line corresponds to the medial branch of the dorsal ramus, which passes through deep muscles such as the multifidus and rotatores and innervates the deep paraspinal muscles and skin. The second lateral line corresponds to the lateral branch of the dorsal ramus, which travels a longer course, emerging through the erector spinae muscles and extending laterally. Although their locations differ, both branches originate from the same segmental spinal nerve root. Thus, stimulation of Hunmen at 3 cun lateral to the spine transmits signals to the same spinal segments as stimulation of Ganshu at 1.5 cun.

All spinal nerve roots connect to the sympathetic trunk via the rami communicantes at the intervertebral foramina. The sympathetic nervous system constitutes the core of the “fight-or-flight” response, directly governing emotion-induced physiological reactions such as tachycardia, gastric spasm, and rapid breathing. When Back Shu points are needled, sensory signals travel through the dorsal rami into the spinal cord and influence the segmentally related sympathetic ganglia via reflex arcs.

The back is also covered by the thickest and most complex fascial structure in the body—the thoracolumbar fascia. Psychologist Wilhelm Reich proposed that chronic emotional repression leads to persistent stiffness in specific muscle groups and fascia, forming what he termed “muscular armour”. The second lateral line of the Bladder channel lies along the outer edge of the erector spinae, where the back muscles and thoracolumbar fascia interweave most densely and bear the greatest tension. Anxiety and defensive postures, such as rounded shoulders and a hunched back, directly lead to thickening and adhesion of the fascia along the second lateral line between T3 and T9, corresponding to the Heart, Lung, and Liver regions.

Modern anatomical research has identified several types of receptors within the thoracolumbar fascia that are key to the effects of acupuncture:

Ruffini corpuscles

Function: Sensitive to sustained pressure and shear forces.

Effect: Needling or manual stimulation of the second lateral line activates Ruffini corpuscles within emotionally tense fascia, sending signals to the brain—particularly the insular cortex—to downregulate sympathetic activity and induce a deep sense of relaxation.

Pacinian corpuscles

Function: Detect high-frequency vibration and rapid changes in pressure.

Effect: Lifting, thrusting, and rotating needle techniques activate these receptors, altering proprioception and interrupting the brain’s fixed perception of bodily tension.

Interstitial receptors (free nerve endings)

Function: Constituting approximately 80% of fascial receptors, they transmit not only pain but also interoceptive signals, the perception of the internal state of the body.

Emotional relevance: Patients with emotional disorders often exhibit disturbed interoception, such as unexplained chest pain or abdominal distension. Stimulating the back fascia can reset the thresholds of these receptors and alleviate somatised symptoms.

The Thirteen Ghost Points of Sun Simiao

Sun Simiao was not only a physician but also a Daoist cultivator. The Thirteen Ghost Points are not merely a group of acupuncture points; they constitute an emergency protocol for the collapse of human mental consciousness. In the worldview of the ancients, the body was likened to a house and the soul (Original Shen) to its owner. When the owner becomes weak or the doors and windows are left unguarded—when upright qi is deficient—external “impurities” (pathogenic influences or spirits) may intrude and take control, leading to incoherent speech, manic agitation, or even abnormal strength, corresponding to conditions such as psychosis, mania, and hysteria. The Thirteen Ghost Points devised by Sun Simiao form a systematic strategy for expelling such intrusions.

Ghost Palace (Renzhong): The main gate. The first needle determines who is in control of the house. If the mind is obscured, this needling acts like a thunderclap, awakening the Original Shen.

Ghost Faith (Shaoshang) and Ghost Fort (Yinbai): Located at the extremities of the hand and foot, these points open the channels of the limbs, preventing pathogenic influences from hiding in dark corners.

Ghost Heart (Daling): A direct strike at the core, targeting the Heart, which stores Shen, to expel pathogenic influences attached to the Heart-Shen.

Ghost Pillow (Fengfu): Located at the back of the head, traditionally considered a point of vulnerability to wind and yin influences. This point blocks retreat and directly attacks pathogenic factors affecting the head.

Ghost Bed (Jiache), Ghost Seal (Haiquan), and others: Used to sweep and clear remaining regions of the body.

If ghosts are translated into severe neuropsychiatric disorders—such as schizophrenia, mania, epilepsy, and hysteria- this system represents a set of highly sensitive and powerful reset mechanisms within the human nervous system.

Renzhong (Ghost Palace) lies in the distribution area of the maxillary branch of the trigeminal nerve. Needling here produces intense nociceptive stimulation, rapidly activating the reticular activating system, a mechanism widely recognised in modern emergency medicine for restoring consciousness. For hysterical coma or stuporous states, such strong stimulation can forcibly reboot the brain.

Shaoshang and Yinbai, as Jing-Well points at the fingertips and toe tips, lie in areas of dense nerve endings. The intense pain signals transmitted to the cerebral cortex can interrupt abnormal neural activity, such as epileptic discharges or compulsive thought loops.

Daling (Ghost Heart) overlies the median nerve. Modern medicine has demonstrated that electrical stimulation of the median nerve can regulate heart rate variability and even alleviate depression, directly influencing autonomic cardiac function and calming tachycardia during manic states.

Fengfu (Ghost Pillow) lies deep and close to the medulla oblongata, the vital centre of life. Needling here can improve vertebrobasilar circulation and directly influence brainstem function, producing tangible physiological improvement in mental symptoms caused by cerebral hypoperfusion or dysregulation.

Jiache (Ghost Bed) targets the masseter muscle, which is among the first to tense during anger or stress. Psychiatric patients often exhibit severe jaw tension. Releasing this area provides proprioceptive feedback to the brain, conveying a signal of relaxation.

The Internal and External Seven Dragons

External Seven Dragons: Resetting the Somatic Defence System

Point combination: Baihui GV20, Dazhu BL11, Shenshu BL23, Pucan BL61 bilaterally, totalling seven needles.Therapeutic aim: To address external stress, trauma, or a sense of being overwhelmed by the environment.

From a modern medical perspective, this constitutes a programme for resetting the sympathetic chain and spinal biomechanics.

1. Central regulation of spinal nerves and the sympathetic trunk. Dazhu (T1) and Shenshu (L2) lie on the first lateral line of the Bladder channel. Dazhu influences the region of the stellate ganglion, regulating sympathetic tone of the head, neck, and upper limbs. Shenshu corresponds to the adrenal glands and directly modulates the hypothalamic–pituitary–adrenal axis, regulating stress hormones such as cortisol and adrenaline. By simultaneously adjusting upper thoracic and lower lumbar sympathetic nodes, the External Seven Dragons calm an overactivated fight-or-flight response.

2. Proprioceptive resetting via Pucan BL61. The heel is the foundation of standing and is rich in high-threshold mechanoreceptors. In states of extreme fear or dissociation, individuals often feel ungrounded. Stimulating the heel transmits strong grounding signals via large Aβ fibres to the spinal cord, anchoring awareness in the body.

Internal Seven Dragons: Resetting the Gut–Brain Axis and Emotional Memory

Point combination: Jiuwei CV15, Tianshu ST25, Futu ST32, Jiexi ST41 bilaterally, totalling seven needles.Therapeutic aim: To address inner psychological distress, deep depression, self-directed aggression, and long-standing emotional trauma.

This method centres on the gut–brain axis.

Jiuwei CV15 lies at the intersection of the phrenic nerve and abdominal branches of the vagus nerve. Anxiety and depression are commonly associated with diaphragmatic tension and shallow breathing. Needling Jiuwei physically releases diaphragmatic spasm, activates parasympathetic activity via the vagus nerve, and initiates the body’s rest-and-digest response.

Tianshu ST25 lies within the rectus abdominis, overlying the small and large intestines. It is the most concentrated projection area of colonic function and a dense reflex zone of the mesenteric nerves, coeliac plexus, and abdominal branches of the vagus nerve. Approximately 95% of serotonin is produced in the gut, and Tianshu is a key point for regulating intestinal motility and the microbiome.

Jiexi ST41 is a key node of the Superficial Front Line. This fascial line stores emotional patterns related to protection, shame, and vulnerability. Depressed individuals often adopt a flexed, foetal posture. Stimulating Jiexi helps release the anterior fascial chain, allowing the body to unfold from a contracted state.

The classical Chinese medical understanding of the spirit is neither abstract philosophy nor symbolic language, but a coherent, clinically grounded system that integrates physiology, psychology, and lived human experience. Shen is not confined to the brain, nor is emotional disturbance reduced to chemical imbalance; rather, mental clarity, emotional stability, and spiritual coherence arise from the orderly governance of the Heart, the free coursing of Liver qi, the nourishment of Blood, and the dynamic communication between the nervous system, fascia, and viscera.
