REN22 (Tiantu, “Celestial Prominence”) is the Window of Heaven point of the Conception Vessel Meridian. It is located on the anterior midline of the neck, in the center of the suprasternal fossa, just superior to the manubrium of the sternum. It descends rebellious Lung and Stomach Qi, benefits and clears the throat, resolves phlegm, and regulates Qi of the chest.

First, insert the needle perpendicularly about 0.2 cun, then angle it inferiorly, guiding it along the posterior aspect of the manubrium for 0.5 to 1.0 cun. This technique avoids puncturing the trachea or lungs.

Tiantu is a primary point for acute and chronic conditions of the throat and lungs. Its ability to descend rebellious Qi makes it essential for treating asthma, wheezing, coughing, and hiccups. It also directly addresses local issues like sore throat, voice loss, and goiter. The classical needling cautions highlight the anatomical sensitivity of the area, a warning that remains critically important in modern practice.

REN22 descends rebellious Lung and Stomach Qi, benefits and clears the throat, resolves phlegm, and regulates Qi of the chest. Common clinical indications include cough, rebellious upward-moving Qi, sudden and severe asthma, wheezing, throat swelling, cold sensation in the throat, broken voice, sores in the throat, hoarseness, inability to speak, coughing up pus and blood, body chills and fever, neck swelling, asthma with gurgling sounds like a water-chicken, chest Qi obstruction, stiffness under the tongue with a blue vein, heart and back pain that pull on each other, the five types of (Yē - dysphagia/choking), jaundice, acid regurgitation (vinegar heart), excessive salivation, vomiting, goiter, tumor, heat in the skin of the face, chest and rib-side fullness, accumulation of Qi in the chest.
First, insert the needle perpendicularly about 0.2 cun, then angle it inferiorly, guiding it along the posterior aspect of the manubrium for 0.5 to 1.0 cun. This technique avoids puncturing the trachea or lungs. Caution: Overlies the thoracic cavity — risk of PNEUMOTHORAX. Needle obliquely or transversely, never deeply or perpendicularly toward the chest wall. Needling too deeply or with an incorrect downward angle can injure the Qi of the five Zang organs and shorten one's life. One source warns that improper needling can cause the patient to die young.
