LI11 (Quchi, “Quchi”) is the He-Sea Point (Earth) point of the Large Intestine Meridian. It is located on the lateral aspect of the elbow, in the depression at the lateral end of the transverse cubital crease when the elbow is flexed. It is located between the lateral epicondyle of the humerus and the brachioradialis muscle. It clears heat, resolves dampness, expels wind, cools the blood, alleviates itching, regulates Qi and Blood, and opens the channel and collaterals.

Quchi is a principal point for clearing heat, expelling wind, and resolving dampness, making it exceptionally effective for a wide range of skin diseases, especially those characterized by heat, redness, and itching like urticaria, eczema, and sores. Its strong action on the channel makes it a key local and distal point for pain, paralysis, and motor impairment of the upper limb, including hemiplegia and Bi-syndrome. As a He-Sea point of a Yangming channel, which is abundant in Qi and Blood, it also treats febrile diseases, clears lingering heat, and addresses certain psycho-emotional disorders like mania and epilepsy.
