You might not think of your inner elbow as the key to better sleep, a healthier heart, and relief from arm pain—but traditional Chinese medicine (TCM) certainly does. Lesser Sea (Shao Hai, HT3) is an important acupoint on the Heart meridian widely used in clinical practice.
Shao Hai helps regulate heart rhythm, improve emotional well-being, and ease tension in the arm. It’s also one of the best points for harmonizing two vital organ systems: the heart and kidneys. Ancient insights and modern science both point to the power of Shao Hai. To locate it, bend your elbow at a 90-degree angle and find the tender spot midway between the inner elbow crease and the bony bump on the inside of the elbow.
