10.2 Auriculotherapy: Ear Anatomy, Point Map, Protocols, and Ear Seeds
Key Takeaways
The auricular map resembles an inverted fetus: the lobe corresponds to the head and face, the antihelix to the spine, the scapha to the upper limb, the crura to the lower limb, and the concha to the internal organs.
Shen Men in the triangular fossa calms the Shen and relieves pain, and Point Zero at the root of the helix is used for overall balance.
The NADA protocol uses five points (Sympathetic, Shen Men, Kidney, Liver, Lung) for addiction, stress, and trauma recovery.
Ear seeds (often Vaccaria seeds), pellets, and magnets are taped to points and pressed several times a day, usually for about 3-5 days, alternating ears.
Avoid inflamed or infected ears, watch for perichondritis with semi-permanent needles, and avoid stimulating reproductive ear points in pregnancy.
10.2 Auriculotherapy: Ear Anatomy, Point Map, Protocols, and Ear Seeds
Quick Answer: Auriculotherapy treats the whole body through points on the outer ear. The map resembles an inverted fetus: the lobe corresponds to the head and face, the antihelix to the spine and trunk, the scapha to the arm, the superior and inferior crura to the leg and buttock, and the concha to the internal organs. Key points include Shen Men (calming, pain), Point Zero (balance), and Sympathetic. The NADA protocol uses Sympathetic, Shen Men, Kidney, Liver, and Lung. Ear seeds, pellets, and magnets extend treatment between visits. The 2026 ACPL outline lists auriculotherapy under point selection and ear seeds, balls, and magnets under adjunctive therapies.
Ear Surface Anatomy
| Structure | Description | Body correspondence |
|---|---|---|
| Helix | Outer rim; begins at the helix root (crus) in the concha | Helix root: diaphragm area (Point Zero region) |
| Antihelix | Ridge inside the helix, dividing into the superior and inferior crura | Body of the antihelix: spine; crura: lower limb and buttock |
| Triangular fossa | Depression between the two crura | Pelvic organs; Shen Men near its apex |
| Scapha | Groove between helix and antihelix | Upper limb (fingers at the top, shoulder lower) |
| Tragus | Flap in front of the ear canal | Adrenal, external nose, throat |
| Antitragus | Bump opposite the tragus | Head and brain |
| Concha | Bowl-shaped hollow; upper cymba and lower cavum | Internal organs: abdominal organs in the cymba, Heart and Lung in the cavum |
| Lobule | Earlobe | Face, eye, teeth, tongue, jaw |
Paul Nogier (France, 1950s) described the inverted-fetus map. China later standardized auricular point names and locations in a national standard (GB/T 13734-2008). Nogier and Chinese charts differ in some locations, so exam items normally test points that both systems share.
Key Auricular Points
| Point | Location (Chinese chart) | Main uses |
|---|---|---|
| Shen Men | Triangular fossa, near the apex | Calms the mind, pain, insomnia, anxiety, withdrawal |
| Point Zero | On the helix root (crus of helix) | Overall balance and homeostasis (Nogier) |
| Sympathetic | End of the inferior crus, under the helix | Autonomic balance, visceral pain, spasms |
| Lung | Cavum conchae, around the Heart point | Respiratory conditions, skin, withdrawal (NADA) |
| Liver | Cymba conchae, posterior part | Irritability, eye problems, detoxification (NADA) |
| Kidney | Cymba conchae, below the inferior crus | Fear, low back, urinary problems (NADA) |
| Stomach | Concha, where the helix root ends | Nausea, appetite, weight management |
| Endocrine | Intertragic notch area | Hormonal and gynecological conditions |
| Ear Apex | Top of the helix when folded | Fever, red eyes, hypertension (bled with a lancet) |
Protocols
- NADA (National Acupuncture Detoxification Association) protocol: five points in each ear: Sympathetic, Shen Men, Kidney, Liver, and Lung. It is used in group settings for substance use disorders, stress, and disaster and trauma recovery. Patients sit quietly with needles retained for about 30-45 minutes.
- Battlefield acupuncture: a sequence of auricular points (Cingulate Gyrus, Thalamus, Omega 2, Point Zero, and Shen Men) used with semi-permanent needles for acute pain, developed for U.S. military medicine.
Four Principles for Choosing Ear Points
Chinese auricular texts describe four ways to select points, and most prescriptions combine them:
| Principle | Example |
|---|---|
| Corresponding area | Knee point for knee pain; Stomach point for epigastric pain |
| Chinese medicine theory | Lung point for skin conditions (the Lung governs the skin); Kidney point for tinnitus (the Kidney opens into the ear); Liver point for eye problems |
| Modern physiology | Endocrine point for menstrual and thyroid-related symptoms; Sympathetic point for visceral spasm and pain |
| Clinical experience | Shen Men for pain and insomnia; Ear Apex bled for fever, red eyes, and high blood pressure |
A typical prescription uses three to six points in one ear, alternating ears at the next visit.
Treatment Procedure
- Select points and confirm them by inspection and palpation.
- Clean the ear with 70% alcohol and let it dry.
- Stabilize the ear with the non-dominant hand and insert a short, fine needle (often 0.5 cun or less) just deep enough to hold, into but not through the cartilage.
- Retain the needles for about 20-30 minutes, or apply seeds or press tacks instead.
- Remove the needles and press each site with dry cotton.
Locating Reactive Points
Before treatment, inspect the ear for discoloration, flaking, small vessels, or nodules. Then palpate with a blunt probe for tenderness. Some practitioners also use an electrical point finder, which detects areas of lower skin resistance. Treat the most reactive points that match the pattern and the complaint.
Ear Seeds, Pellets, and Magnets
| Item | Description | Notes |
|---|---|---|
| Seeds | Small seeds, often Vaccaria (Wang Bu Liu Xing), on adhesive tape | Inexpensive; non-invasive; good for children and needle-phobic patients |
| Pellets (balls) | Small metal (often gold- or silver-plated) or ceramic beads on tape | Firmer stimulation |
| Magnets | Small magnets on tape | Avoid near cardiac pacemakers and implanted defibrillators as a precaution |
| Semi-permanent needles | Press tacks or ASP-type needles left in place | Highest infection risk; inspect the ear daily |
Patient instructions: press each seed firmly for about 30-60 seconds, three to five times a day, or whenever cravings or symptoms arise. Keep them in place for about 3-5 days. Remove them if the skin itches, reddens, or becomes painful. Alternate ears between treatments to let the skin rest.
Precautions and Contraindications
- Do not treat ears with infection, inflammation, eczema, open wounds, or frostbite.
- Perichondritis (infection of the ear cartilage, sometimes Pseudomonas) is a serious complication. Red, hot, swollen, painful ear cartilage requires prompt medical referral, especially after semi-permanent needling.
- In pregnancy, avoid stimulating the Uterus and Endocrine points, and avoid strong stimulation in general.
- Clean the ear with 70% alcohol before needling, and press firmly after removal because ear points bleed easily.
- Patients can feel faint during auricular needling, so treat them seated or lying down.
A patient in a community recovery program receives five auricular points in each ear: Sympathetic, Shen Men, Kidney, Liver, and Lung. Which protocol is this?
Battlefield acupuncture
The NADA protocol
Nogier's Point Zero protocol
The Four Gates
On the auricular map, which area corresponds to the face, eyes, and teeth?
The scapha
The superior crus of the antihelix
The lobule (earlobe)
The cymba conchae
Two days after semi-permanent ear needles were placed, a patient reports that the upper ear is red, hot, swollen, and very painful. What should the practitioner do?
Press the needles harder to strengthen the treatment and clear the Heat
Leave the needles in for the planned five days
Apply moxibustion to the ear to clear the stagnation and reduce the swelling and redness
Remove the needles and refer promptly for evaluation of possible perichondritis
A patient is given ear seeds for anxiety and insomnia. Which instruction is appropriate?
Leave the seeds in place for at least four weeks without touching or pressing them, so the skin and points can adapt
Press each seed 30-60 seconds several times daily, keep them on 3-5 days, and remove them if the skin gets sore
Moisten the seeds with alcohol every hour to keep the adhesive tape and skin clean
Apply them only to Point Zero and never to Shen Men, which is reserved for needling alone
