Xin Shu (BL15): The Heart Back-Shu Point for Palpitations, Insomnia, and Calming the Spirit
Explore Xin Shu (心俞 BL15), the Heart's Back-Shu point on the Bladder meridian. Learn its location, functions for calming the spirit, treating palpitations, anxiety, insomnia, and chest discomfort.
Introduction to Xin Shu
Xin Shu (心俞, BL15) is the Back-Shu point (背俞穴) of the Heart, located on the Bladder Meridian of Foot-Taiyang at the level of the 5th thoracic vertebra. In TCM theory, the Heart is the “Emperor” of the organ system — it houses the Shen (spirit), governs Blood, and controls the mind. Xin Shu is the point where Heart Qi rises to the surface and can be directly accessed.

3. Clear Heart Heat (清心热)
- Red face and red eyes
- Mouth ulcers on the tongue
- Bitter taste in the mouth
- Nighttime restlessness and insomnia
- Red tongue tip
4. Nourish Heart Blood (养心血)
- Poor memory and difficulty concentrating
- Dizziness and lightheadedness
- Pale complexion
- Insomnia with many dreams

Acupressure Self-Care
Tennis Ball Method
- Stand with your back to a wall
- Place a tennis ball at the Xin Shu level (T5, between the shoulder blades)
- Lean into the ball with gentle pressure
- Hold for 30–60 seconds, breathing deeply
- The area may feel tender — this is normal with Heart-related tension
Cross-Body Reach
- Reach across your chest with your right hand to the left shoulder blade area
- Use your fingers to gently press and massage the area between the spine and shoulder blade at the upper-mid back level
- Repeat on the other side
- This provides indirect stimulation to the Xin Shu area
Partner Technique
- Receiver sits comfortably or lies face down
- Giver locates the point at T5 level, 1.5 cun from the spine
- Apply gentle, steady thumb pressure — do not press too hard
- Use a warm palm to cover the upper back area
- Hold for 1–2 minutes per side
Gentle Tapping
- Using loose fists, gently tap the upper back between the shoulder blades
- This stimulates the entire upper Bladder meridian line, including Xin Shu

Moxibustion on Xin Shu
Moxibustion on Xin Shu is beneficial for:
- Cold-type Heart patterns — chest coldness, cold hands
- Heart Yang deficiency — pale face, fatigue, shortness of breath
- Insomnia from Heart deficiency — difficulty sleeping, pale complexion
- Post-illness Heart weakness — after febrile disease or severe illness
Method
Use a moxa stick held 2–3 cm above the point for 5–10 minutes per side. Shorter duration than other points — the Heart area is sensitive. Stop if the warmth feels uncomfortable.
Caution: Do not use moxibustion on Xin Shu for Heart fire patterns (red face, insomnia with agitation, red tongue tip).
The Heart in TCM: Why Xin Shu Matters
The Heart in TCM is far more than a blood pump. It is:
- The residence of the Shen (spirit) — consciousness, thinking, memory
- The Emperor of the organs — all other organs report to and protect the Heart
- The governor of Blood — Blood follows the Heart’s command
- The opening into the tongue — speech and taste reflect Heart health
- Associated with Joy — both its virtue and its vulnerability
When the Heart is disturbed, the entire person is affected — mind, emotions, sleep, and even speech. Xin Shu provides direct access to this vital organ.
Precautions
- Pregnancy — use caution; avoid strong stimulation
- Acute cardiac conditions — always rule out serious heart disease first; Xin Shu does not replace emergency cardiac care
- Heart fire patterns — avoid moxibustion; use acupressure or clearing techniques instead
- Excessive pressure — the upper back area can be sensitive; use moderate pressure
- Skin conditions — avoid if wounds or rashes are present
Key Takeaways
- Xin Shu (BL15) is the Heart’s Back-Shu point at T5 level — direct access to Heart Qi
- Primary function: calm the spirit (Shen) and regulate Heart Qi and Blood
- Essential for palpitations, anxiety, insomnia, poor memory, and chest discomfort
- The Heart “houses the spirit” — Xin Shu calms the mind by calming the Heart
- Combine with Shenmen (HT7) and Neiguan (PC6) for the strongest calming effect
- Use gentle pressure — the upper back and Heart area require a lighter touch

FAQ
What is Xin Shu used for?
Xin Shu (心俞, BL15) is the Back-Shu point of the Heart, located on the back at the level of the 5th thoracic vertebra (T5). It is used to calm the spirit (Shen), regulate Heart Qi, and treat conditions involving the Heart organ system. Common applications include palpitations (racing or irregular heartbeat), insomnia (especially with anxiety), anxiety and panic, chest tightness, poor memory, and emotional distress. As a Back-Shu point, it provides direct access to Heart Qi, making it one of the most important points for any Heart-related condition in TCM.
Can stimulating Xin Shu help with anxiety attacks?
Yes, Xin Shu is one of the primary acupoints used in TCM for anxiety and panic. The Heart in TCM 'houses the spirit (Shen)' — when Heart Qi is disturbed, the spirit becomes agitated, causing anxiety, palpitations, and restlessness. Stimulating Xin Shu helps calm the spirit and regulate Heart Qi. For acute anxiety, firm pressure on Xin Shu combined with Shenmen (HT7) and Neiguan (PC6) can provide relief. However, chronic anxiety typically requires a comprehensive treatment approach including herbal formulas, dietary therapy, and lifestyle changes alongside acupuncture.
