ST9 (Renying, “Man's Welcome”) is the Window of the Sky point of the Stomach Meridian. It is located on the lateral side of the Adam's apple, at the level of the superior border of the thyroid cartilage, in the depression between the sternocleidomastoid muscle and the trachea, where the common carotid artery pulsates. It regulates Qi and blood, calms dyspnea, clears heat.
On the lateral side of the Adam's apple, at the level of the superior border of the thyroid cartilage, in the depression between the sternocleidomastoid muscle and the trachea, where the common carotid artery pulsates.
Perpendicular insertion 0.3-0.5 cun, avoiding the carotid artery and jugular vein. Extreme caution is advised.
Regulates Qi and blood, calms dyspnea, clears heat.
Sore throat, asthma, goiter, scrofula, hypertension.
As a Window of the Sky point, ST9 is crucial for regulating Qi and blood in the head and neck, making it a significant point for both excess and deficiency patterns. It is known for calming dyspnea and clearing heat, especially in conditions like hypertension and goiter. Its proximity to the carotid artery requires careful palpation and shallow needling. It is empirically used for regulating blood pressure.
ST9 is one of 45 points on the Stomach Meridian. Nearby points:

ST9 regulates Qi and blood, calms dyspnea, clears heat. Common clinical indications include sore throat, asthma, goiter, scrofula, hypertension.
Perpendicular insertion 0.3-0.5 cun, avoiding the carotid artery and jugular vein. Extreme caution is advised. Caution: ⚠ Major vessel/nerve nearby — palpate first; avoid deep insertion (near the carotid artery).
