Collarbone Point (ST12) Complete Guide: Exact Location and Acupressure Techniques for Cough and Asthma

What is the Jueyin (ST12) Acupoint?

The Jueyin acupoint belongs to the Stomach Meridian of Foot-Yangming, and is known as a convergence point.

In traditional Chinese medicine, the Jueyin is widely used for neck and upper chest symptoms. It is particularly effective when respiratory discomfort and muscle tightness around the neck are present simultaneously.

Exact Location of the Jueyin

The Jueyin is located approximately 3.5-4 cun (10-12cm) outward from the center line of the neck at the hollow area above the clavicle.

More precisely, it is the point encountered when moving laterally from the depressed area above the clavicle (supraclavicular fossa). When you slightly lower your head and press with your finger, you should feel slight pain or soreness at this tender point.

Finding the Jueyin in 3 Steps

1. Locate the Clavicle: Lower your head slightly forward. You will see a hollow depression above the clavicle. This is the reference point you need to find.
2. Measure Outward from the Center Line: From the center of the neck (midline), move outward about 3-4 finger widths (approximately 3.5-4 cun). The distance is the same on both sides.
3. Confirm the Tender Point: When you gently press that point with your finger, you should feel slight pain or soreness. This is the exact Jueyin location.

Initial Learning Tip: It can be difficult to find the exact location initially. During a visit to a clinic, having a practitioner mark the location or correct your finger position will make subsequent self-massage much more accurate.

Effective Jueyin Acupressure Method

The basic technique is 3-second press-breathing repetition, performed 2-3 times daily for 5-10 minutes each time.

Step-by-Step Acupressure Technique

1. Choose Your Finger: Use your thumb or middle finger. Press with the fingerprint area without the fingernail.
2. Appropriate Pressure: Maintain a pressure level of “pleasantly sore” (known in medical terms as soreness and distension sensation). It is important to maintain consistent intensity rather than pressing too deeply.
3. Acupressure with Breathing: Press for 3 seconds while slowly exhaling. While inhaling, maintain about 50% of the finger pressure, then press again while exhaling.
4. Repetition Count: Repeat the above motion 5-10 times (approximately 1 minute). Perform this 2-3 times per day.

Enhancing Effects with Warm Acupressure

Performing the following before acupressure improves blood circulation for greater effectiveness:

• Cover the neck area with a warm damp cloth (40-45°C) for 2-3 minutes
• Or perform acupressure immediately after a warm shower
• Or apply a heating pad to the neck area for 5 minutes before acupressure

Real Experience: Warm acupressure is particularly effective when muscle tension is severe (office workers who sit for long periods, or those with stiff neck from stress). Warming a neck exposed to cold air results in less pain during acupressure and more noticeable relaxation effects.

Jueyin Acupressure Effects by Symptom

Although the Jueyin belongs to the Stomach Meridian, it has widespread effects on the respiratory system and neck muscles. In traditional Chinese medicine, this is explained as a “meridian intersection point.”

When is Jueyin Acupressure Most Effective?

Optimal Times

• Within 30 minutes after waking in the morning: Promotes blood circulation around the neck before starting the day. Also good for cold prevention.
• 30 minutes before bedtime: Relieves neck tension to promote better sleep and is effective in reducing nighttime cough.
• Immediately when cough or sore throat occurs: Applying acupressure early before symptoms worsen enables faster relief.

Effective Situations

Precautions When Applying Jueyin Acupressure

Contraindicated Situations (Cases to Avoid)

• Acute pharyngitis accompanied by high fever: If fever is 40°C or above, consult a healthcare provider for medical diagnosis first. Stimulating the Jueyin may increase fever.
• Severely swollen tonsils from tonsillitis: If swelling in the neck area is severe, acupressure may worsen the condition. Follow your doctor’s advice.
• Open wounds or skin conditions on the neck: Avoid stimulation while wounds are healing.
• Extreme fatigue or low blood sugar: Minimize stimulation when the body is in a very weak state.

Pregnancy Precaution

Important Points During Acupressure

• Avoid Excessive Force: “Pleasantly sore” is the appropriate level. Be careful not to press so hard that bruising occurs or severe pain appears on the skin.
• Block Cold Air After Acupressure: Avoid exposure to cold air for 30 minutes after acupressure. If the body receives cold after blood circulation is promoted, adverse effects can occur.
• Warm Beverage After Acupressure: Drinking warm ginger tea or jujube tea enhances the acupressure effects.
• Avoid Excessive Frequency: Do not continue for more than 10 minutes at a time, or repeat more than 4 times per day.

Signals That Medical Consultation is Needed

Stop acupressure and consult a healthcare professional if:

• Swelling in the neck area increases after acupressure
• Severe pain persists for more than 24 hours
• Cough or sore throat continues for more than 3 weeks
• Shortness of breath worsens
• High fever (38°C or above) is present

Expected Effects and Actual Sensations from Jueyin Acupressure

Normal Sensations: During acupressure, you may feel a “pleasantly sore” sensation (increased venous blood flow), slight warmth, and a “relieved soreness” sensation around the neck area.

Timeline for Effects: Acute cough often shows improvement within 5-10 minutes, while chronic neck stiffness typically requires consistent acupressure for 3-5 days before noticeable changes appear.

Integrated Approach for Better Respiratory Health

While Jueyin acupressure is effective alone, it is more effective when combined with the following:

• Stretching: Slowly pull neck to the side, interlace fingers behind neck and stretch backward (30 seconds × 3 times)
• Warm Compress: Apply a warm heating pad to the neck area for 10 minutes every evening
• Breathing Exercise: Strengthen the diaphragm through abdominal breathing
• Humidity Control: Maintain indoor humidity at 50-60% to protect respiratory health
• Adequate Hydration: Consume 1.5-2L per day to maintain mucous membrane health

Poor posture in modern people (forward head posture, rounded shoulders) is a major cause of neck and respiratory discomfort. Maintaining correct posture together with Jueyin acupressure is the fundamental solution.
