Ermen

What is TE21?

TE21 (Ermen) is a point just in front of the ear, in the small notch above the tragus that opens into a dip when you open your mouth.

Its Chinese name, Ermen, means "ear gate". It is the last point on the Triple Energizer channel, which runs from the ring finger up the arm, across the shoulder and around the ear. TE21 sits at the top of a stack of three classical ear points: TE21 above, SI19 in the middle and GB2 below. All three are less than a finger-width apart.

In classical texts TE21 is an ear and jaw point. It was used for ringing in the ears, muffled hearing, ear discharge, toothache in the upper back teeth, and a stiff or painful jaw joint. That long history tells you the point was valued and widely taught. It does not tell you the point works, and it does not tell you the point is safe for you — those are separate questions, and this page keeps them separate.

The honest verdict on evidence: there is essentially no research on finger pressure applied to TE21 on its own. TE21 does appear in acupuncture studies of tinnitus, where it is needled alongside several other points, so no result can be traced back to this point alone. Reviews of those trials describe them as small, short and poorly blinded, with inconsistent results. Nothing here supports a claim that TE21 restores hearing or removes tinnitus.

What is fair to say is that gentle pressure in front of the ear is a low-cost, low-risk thing to try for jaw tension and ear fullness, as long as you treat it as comfort rather than treatment. The area overlies the temporomandibular joint (the jaw hinge) and sits near the superficial temporal artery, so pressure should stay light. If a symptom is new, one-sided, or getting worse, the point is not the answer — a doctor is.

Where is TE21 and how do you find it?

TE21 sits in front of the top of your ear, in the hollow above the tragus that deepens when you open your mouth.

• Find the tragus. This is the small flap of cartilage that points backwards over the opening of your ear canal. Rest a fingertip on it.
• Slide up to the notch. Move your finger up along the front edge of the ear until you feel a small gap in the cartilage at the top of the tragus. This is the supratragic notch.
• Step forward, not in. From that notch, move your fingertip forward about half a centimetre, towards your face. You should be on soft tissue, not on the ear itself.
• Open your mouth. As your jaw drops, the bony knob of the jaw joint slides forward and a clear dip appears under your finger. That dip is TE21.
• Check by closing. Close your mouth and the dip fills in as the jaw bone returns. If the hollow appears and disappears as you open and close, you have the right spot.

Classical texts place TE21 in front of the supratragic notch, at the back edge of the jaw's condyle (the rounded top of the jawbone). It is roughly a finger-width above GB2 and just above SI19. Because the three points are so close together, treat the mouth-open dip as your landmark rather than trying to split hairs between them.

Two things to feel for as you search. First, a pulse: the superficial temporal artery runs upward just in front of the ear, and if your finger is on a throbbing line you have drifted slightly forward or up. Second, bone: if the spot feels hard and unyielding with your mouth open, you are too far back onto the ear cartilage or too far down onto the jaw. TE21 should feel soft and slightly tender at most.

This is a surface landmark for fingertip pressure only. No instruction here involves anything entering the skin.

How do you apply pressure to TE21?

1. Wash your hands. You are working right beside the ear canal and on facial skin, so clean hands and short nails matter.
2. Sit somewhere settled. A chair with back support is ideal. Working on your own face while standing or walking makes it hard to judge pressure.
3. Open your jaw slightly. Let your mouth drop open about a centimetre so the dip in front of the ear appears under your fingertip.
4. Use the flat pad of one finger. The index or middle finger works best. Press straight in towards the centre of your head, not forwards into your cheek and not backwards into the ear.
5. Keep the pressure light. Aim for firm contact that feels like a dull ache at most — around 2 or 3 out of 10. This area sits over the jaw joint and near an artery, so it is not a place for deep digging.
6. Hold or circle for 30 to 60 seconds. Either steady pressure or slow, small circles is fine. Breathe normally rather than holding your breath.
7. Do both sides. You can work one at a time, or use both index fingers together in front of both ears.
8. Repeat two or three times a day. Short, regular sessions are more comfortable than one long one. A few minutes in total per day is plenty.

Stop straight away if you feel sharp pain, a click or a lock in the jaw, dizziness, a strong throb under your finger, or ringing that gets louder. Stop also if the skin becomes red, sore or tender to touch afterwards.

Letting your jaw rest in a relaxed position — teeth apart, tongue resting behind the upper front teeth — while you press tends to make the area less tender. If pressing is only comfortable when you clench, you are pressing too hard.

Give it a fair but limited trial. If a week or two of regular use changes nothing about your symptom, finger pressure on TE21 is unlikely to be the tool for it.

What is TE21 traditionally used for?

• Tinnitus (ringing or buzzing in the ears). This is the headline traditional use, and the "ear gate" name reflects it. Human evidence is weak: TE21 appears in acupuncture trials for tinnitus but always combined with other points, and reviews of those trials report small sample sizes, poor blinding and inconsistent results. No trial has tested finger pressure on TE21 alone.
• Muffled hearing and ear fullness. Classical texts list deafness and blocked ears among its uses. There is no controlled human research showing that pressure here improves hearing. Fullness linked to jaw tension or congestion may feel briefly easier, which is not the same as hearing improving.
• Jaw joint pain and clicking. TE21 sits directly over the temporomandibular joint, so it is widely used in modern practice for jaw tension and TMJ discomfort. Trials of manual therapy and massage around the jaw show modest short-term relief, but those studies tested whole treatment approaches, not this point.
• Toothache in the upper back teeth. A traditional use, probably because the point lies near nerves serving the upper jaw. There is no useful human evidence. Toothache has a cause, and that cause needs a dentist.
• Ear discharge and earache. Listed classically. Modern safety advice points the other way: a discharging or infected ear is a reason to avoid pressing here and to see a doctor.
• Tension around the temple. Many people find light pressure in front of the ear relaxing when they have been clenching. This is plausible as general comfort from touch and muscle release, not a specific point effect.
• Lockjaw and jaw stiffness. Traditional sources mention difficulty opening the mouth. Gentle pressure may ease muscle tightness; a jaw that genuinely locks shut or open needs assessment, not self-treatment.

Across all of these, the pattern is the same: strong traditional standing, almost no point-specific human evidence. Treat TE21 as something that may feel soothing while you deal with the actual cause elsewhere.

Are there tips for using TE21 effectively?

• Let the dip find itself. Open your mouth before you press rather than hunting for the spot with your jaw closed. The hollow in front of the ear is only obvious when the jaw bone has slid forward.
• Use the finger pad, never the nail. The skin here is thin and sits over bone and cartilage. A nail edge causes a sting that masks whatever the pressure itself is doing.
• Feel for the pulse first. Rest your finger lightly for a few seconds before pressing. If you feel a steady throb, shift your contact point slightly until you do not, then press.
• Pair it with jaw release. Unclench your teeth, let the tongue rest on the roof of the mouth and drop the shoulders. For jaw tension, the posture change often does more than the point.
• Keep sessions short and frequent. Three one-minute sessions spread through the day beat one long grind. The jaw joint area gets sore quickly from sustained pressure.
• Work both sides even for one-sided symptoms. It keeps the jaw muscles balanced and stops you leaning into one side too hard.
• Try warmth instead on a tender day. A warm flannel over the jaw joint for a few minutes is gentler than pressure when the area is already sore, and is often more comfortable.
• Keep a short log. Note the symptom score before and after for a week. Tinnitus and jaw pain both fluctuate on their own, and a written record is the only way to tell real change from a good day.
• Set a stopping point. Decide in advance that two weeks without change means you move on. Open-ended self-treatment delays a proper diagnosis.
• Do not combine it with earbuds or loud listening. If ringing is your concern, protecting your hearing from loud sound does far more than any pressure point.

What do people get wrong with TE21?

• Expecting a cure for tinnitus. This is the biggest one. Videos often promise that pressing TE21 ends ringing in the ears. Nothing in the research supports that, and chasing it can delay a hearing assessment that would actually be useful.
• Pressing far too hard. TE21 lies over the jaw joint. Heavy pressure can leave the joint aching for a day or more, especially in someone who already clenches or grinds.
• Searching with the mouth closed. With the jaw shut, the condyle fills the hollow and the whole area feels like bone. People then press on bone and conclude the point does nothing.
• Drifting into the ear canal. Some readers interpret "ear gate" as meaning inside the ear. TE21 is in front of the tragus, on the face. Nothing should go into the canal.
• Confusing it with its neighbours. SI19 and GB2 sit within a finger-width below TE21. That closeness is normal and the dip-on-opening landmark is the reliable way to aim for TE21 specifically.
• Working through a pulse. The superficial temporal artery passes just in front of the ear. If you feel throbbing under the fingertip, move slightly and ease off rather than pressing harder.
• Using it on an infected ear. Pain, fever or discharge from the ear is a reason to see a doctor, not a reason to press beside it.
• Ignoring sudden hearing loss. Hearing that drops suddenly in one ear needs medical assessment within days. Self-treating that with a pressure point can cost the treatment window.
• Treating tradition as safety clearance. That a point is ancient says nothing about whether it suits your jaw, your skin or your current condition.
• Giving it no fair test. Pressing once and judging it is as unhelpful as pressing for months with no change. A short, logged trial is the honest middle.

What does the research on TE21 actually say?

There is no useful human research on finger pressure applied to TE21 on its own. No controlled trial has isolated this point and tested acupressure against a credible sham for tinnitus, hearing, jaw pain or toothache. That is the plain answer, and it should shape your expectations.

What does exist sits one step removed. TE21 is a standard local point in acupuncture protocols for tinnitus and for ear-region complaints, so it turns up inside needling trials alongside points such as SI19, GB2 and various distal points on the limbs. Those trials needled the points; they did not test finger pressure, and this page does not describe needling because it is not something to do at home.

Systematic reviews of acupuncture for tinnitus have repeatedly reached a cautious conclusion: the studies are mostly small, often conducted at single centres, rarely blinded well, and frequently short in follow-up. Results across them are inconsistent, with some reporting reduced loudness or distress scores and others finding no difference from sham. Because every protocol used several points at once, no finding can be attributed to TE21.

Research on jaw joint pain is a slightly better-populated field, but again not a point-specific one. Trials of manual therapy, massage and self-managed exercise for temporomandibular disorders generally report modest short-term improvements in pain and mouth opening. TE21 happens to lie over the area those studies treat, which makes gentle pressure there plausible as part of general jaw care — but plausible is not proven, and the studies were not testing an acupressure point.

What this means for you is simple. Treat TE21 as a traditional landmark worth a gentle, time-limited try for jaw tension or ear fullness, with no expectation of changing hearing or clearing tinnitus. Keep your own record over a week or two. If nothing shifts, or if symptoms are new, one-sided or worsening, move on to a doctor, dentist or audiologist rather than pressing harder or longer.
