Neiguan (PC6): The Point for Nausea, Anxiety, and Heart Health

Introduction to Neiguan

Neiguan (内关, PC6), meaning “Inner Pass,” is one of the most clinically versatile and widely used acupoints in Traditional Chinese Medicine. Located on the inner forearm, this point serves as a gateway to regulating the Heart, Stomach, and mind.

As a Luo-Connecting point (络穴) of the Pericardium Meridian and one of the Eight Confluent Points (八脉交会穴) linking to the Yin Linking Vessel (阴维脉), Neiguan has a remarkable breadth of clinical application. It is perhaps best known in both traditional and modern contexts for its powerful anti-nausea effect.

Location

Neiguan is located on the anterior aspect of the forearm:

Standard location: 2 cun proximal to the wrist crease (掌横纹), between the tendons of palmaris longus and flexor carpi radialis
Easy method: Place three fingers (index, middle, ring) across the inner wrist from the crease. Neiguan lies at the level of the ring finger, between the two visible tendons when you flex your wrist slightly

Key Functions

Neiguan’s functions span three major systems:

1. Calm the Mind and Regulate the Heart

As a point on the Pericardium Meridian, Neiguan directly influences the Heart. It is used for:

Anxiety and panic attacks — calms shen (spirit), reduces palpitations
Insomnia — especially when related to overthinking or worry
Chest oppression — relieves tightness and emotional constriction
Palpitations — regulates heart rhythm from a TCM perspective

2. Harmonize the Stomach and Relieve Nausea

Neiguan’s connection to the Yin Linking Vessel gives it a powerful effect on the middle jiao (中焦):

Nausea and vomiting — the most famous application of this point
Motion sickness — widely used in wristband form
Morning sickness — safe and effective during pregnancy
Acid reflux and hiccups — redirects rebellious Stomach Qi downward

3. Unblock the Chest and Relieve Pain

Angina and chest pain — historically used for heart discomfort
Hypochondriac pain — pain in the rib-side area
Costochondritis — inflammation of chest wall cartilage

Clinical Applications in Detail

Nausea and Vomiting

Neiguan is the most researched acupoint for nausea in modern medicine. Its applications include:

Post-operative nausea and vomiting (PONV): Multiple clinical trials show significant reduction when PC6 is stimulated
Chemotherapy-induced nausea: Used as a complementary therapy in oncology settings
Morning sickness: Safe for use during pregnancy, often applied via acupressure wristbands
Motion sickness: Sea-Band and similar products target this exact point

Anxiety and Emotional Distress

From a TCM perspective, Neiguan calms the Shen (spirit) and regulates the Pericardium, which acts as the Heart’s protector:

Generalized anxiety
Pre-performance jitters
Exam stress
Grief and emotional constriction in the chest

Cardiac Symptoms

While not a replacement for emergency medical care, Neiguan has traditional applications for:

Mild angina-like chest discomfort
Palpitations from stress or caffeine
Chest tightness from anxiety

Modern Research

Neiguan (PC6) has more clinical research behind it than almost any other acupoint:

FDA recognition: Acupressure wristbands targeting PC6 are FDA-cleared for nausea relief
Cochrane Review: A meta-analysis of 59 trials found PC6 stimulation significantly reduced post-operative nausea
Mechanism studies: fMRI research shows PC6 stimulation activates brain regions associated with nausea processing and autonomic regulation
Chemotherapy studies: Systematic reviews support PC6 acupressure as an effective adjunct for chemotherapy-induced nausea

Acupressure Self-Care Technique

Neiguan is one of the easiest acupoints for self-treatment:

For Nausea

Turn your palm face-up
Place three fingers across your wrist from the crease
At the level of the ring finger, press between the two tendons
Apply firm, steady pressure with your thumb
Hold for 2–3 minutes while breathing deeply
Repeat on the other wrist if needed

For Anxiety

Find the point using the same method
Use a gentler, circular massage motion
Breathe slowly and deeply while massaging
Continue for 3–5 minutes
Combine with slow exhalation for enhanced calming effect

For Motion Sickness

Apply pressure before travel begins (prevention is more effective)
Use constant moderate pressure rather than massage
Maintain pressure for the duration of exposure if possible
Acupressure wristbands provide hands-free stimulation

Technique	Pressure	Duration	Best For
Firm press	Moderate–strong	2–3 min	Nausea
Circular massage	Gentle–moderate	3–5 min	Anxiety
Steady hold	Moderate	Continuous	Motion sickness

Famous Point Combinations

Neiguan (PC6) + Zusanli (ST36)

The classic pairing for digestive disorders. Neiguan directs Qi downward and stops vomiting, while Zusanli strengthens Spleen and Stomach. Together they address:

Chronic nausea with poor appetite
Vomiting with fatigue
Acid reflux with weakness

Neiguan (PC6) + Shenmen (HT7)

A powerful combination for calming the mind:

Insomnia with anxiety
Palpitations from emotional stress
Restlessness and overthinking

Neiguan (PC6) + Hegu (LI4)

Used for upper body conditions:

Headache with nausea
Toothache with anxiety
Facial conditions

Moxibustion on Neiguan

Moxibustion can be applied to Neiguan for:

Chronic cold-type nausea (nausea worsened by cold foods)
Chest cold and oppression
Weak digestion with cold extremities

Use mild moxa for 5–10 minutes per point. The warming sensation should be comfortable, never burning.

Precautions

Pregnancy: Generally safe and commonly used for morning sickness, but consult a practitioner before using strong pressure or acupuncture
Broken skin: Do not apply pressure over wounds, rashes, or bruises
Heart conditions: While traditionally used for cardiac symptoms, always seek emergency medical care for acute chest pain
Over-stimulation: Excessive pressure may cause local soreness or bruising — use moderate, consistent force
