Auricular Therapy and Ear Seeds: What They Are and What Research Shows
Auricular therapy stimulates points on the ear with needles, seeds or beads; this guide covers ear seeds, what reviews found for pain, sleep and nausea, skin reactions and how to check training.

What it is
Auricular therapy means stimulating specific areas of the outer ear. Auricular acupuncture does this with needles. [1] Auricular acupressure, often called ear seeds, places plant seeds or magnetic beads on points on the ear and applies pressure to them. [2]The ear-point maps used in practice are a traditional and modern clinical framework. They are not proof that body organs are "mapped" on the ear. Needle-based ear acupuncture belongs to the acupuncture area; see What Is Acupuncture?, Acupuncture Methods and Acupressure. This page gives no instructions for placing seeds or needles yourself.
What research found
Several reviews pooled Chinese-language and hospital trials, and without a sham (look-alike) control people may know whether they got seeds. Most reviews below rate their own evidence as low quality.| Use | What the source found | Strength of evidence |
|---|---|---|
| Pain around surgery (auricular acupuncture) | 21 trials (1,527 people): pain and pain medicine use were lower; the authors say evidence quality is low [3] | Promising but limited |
| Chronic back and cancer pain (auricular acupuncture) | NCCIH describes promising results [1] | Promising but limited |
| Battlefield acupuncture (a quick ear-needle method) | A 2021 review of 9 studies found no significant pain improvement vs no treatment, usual care, delayed treatment or sham [1] | No good evidence of benefit |
| Insomnia | 23 trials (1,689 people); no serious adverse events reported [4]. In cancer patients, 14 trials (1,073) with low quality and high variation [5] | Promising but limited |
| Painful periods | 35 trials (3,960 people); benefit mostly seen against analgesics or no treatment, not when seeds were used alone against other treatments [6] | Mixed |
| Constipation in adults | 34 trials (2,465 people); evidence low to very low [7] | Insufficient evidence |
| Overweight and obesity | Review of 8 trials suggests benefit; the authors want better blinded trials [8] | Insufficient evidence |
| Chemotherapy nausea | A review of 14 studies of P6 and ear acupressure concluded it is helpful as a complement [9] | Insufficient evidence (mixed with P6, which is not an ear point) |
Label for most uses: promising but limited to insufficient evidence. For related conditions see TCM for Insomnia and Sleep, TCM for Menstrual Pain and TCM for Nausea and Chemotherapy Side Effects.
Training and finding care
Ear needling is part of acupuncture practice, and licensing differs by jurisdiction. See Acupuncture Practitioner Licensing and Training and How to Choose a TCM Practitioner. We found no regulator page that governs ear seeds specifically. We do not list practitioners or sellers; ask for training, how the skin is cleaned, and what happens if you react.Frequently asked questions
What are ear seeds?
Plant seeds or magnetic beads placed on points on the ear and pressed. [2]
Do ear seeds work?
Some reviews report benefit for sleep and period pain, but quality is low and results vary. [4][6]
Are ear seeds safe?
Reviews found mostly mild events such as skin irritation. [10]
What is battlefield acupuncture?
A quick ear-needle method used by US military and veterans' services; a 2021 review found no significant pain improvement. [1]
Can I put them on myself?
We do not give instructions. Ask a trained practitioner or your clinician.

Side effects
In a review of 15 trials in women with breast cancer, adverse events included skin allergic reaction (10 of 259 people, 3.9%), bruising (2.7%), pain (1.2%) and local pressure ulcers on the ear points (0.8%). [2] One review also found no significant difference in adverse events versus controls in constipation trials. [7] For needle-based ear acupuncture, NCCIH notes complications have resulted from nonsterile needles and improper delivery. [1] Reported events after perioperative ear acupuncture were mainly nausea, vomiting and drowsiness. [3]
