**CV 17 (*Tan Zhong* / *Shanzhong*)** is one of the most powerful points in acupuncture and acupressure for regulating chest energy, respiratory function, and emotional health.
1. **Location & Anatomical Placement**
* **Location**: Found on the midline of the sternum (breastbone), at the level of the fourth intercostal space (midpoint between the two ni***es in men).
# # # 2. **Core Functions & Channel Energetics**
* **Sea of Qi & Front-Mu Point**: CV 17 serves as the **Hui-Meeting Point of Qi** and the **Front-Mu point of the Pericardium**. It acts as the central gathering basin for *Zong Qi* (Gathering/Ancestral Qi), which drives both respiration and cardiac rhythm.
* **Relieves Chest & Respiratory Symptoms**: It opens the thoracic cavity, descends rebellious Lung Qi, and relieves chest tightness, oppression, asthma, coughing, wheezing, and palpitations.
* **Psycho-Emotional Unbinding**: Known as the "Middle Altar," CV 17 is a primary portal for releasing stored emotional trauma, panic attacks, anxiety, and unexpressed grief. It helps unbind the chest armor, allowing the Heart spirit (*Shen*) to settle into peace.
* **Supports Breast Health**: It regulates chest circulation to promote lactation and treat breast distension, tenderness, or mastitis.
3. **Self-Care Acupressure Technique**
* Place a thumb or index fingertip on the center of the sternum at CV 17.
* Apply gentle, steady pressure while making small clockwise circular motions.
* Inhale deeply into your lower abdomen, then exhale slowly for about 15 breaths to help lower your heart rate and reset your nervous system.
