Daying is a primary local point for disorders affecting the jaw, teeth, and facial muscles. It is particularly effective for conditions caused by wind, such as facial paralysis, lockjaw, and trigeminal neuralgia, often combined with distal points like Hegu (LI4). Its ability to treat scrofula and neck swellings is well-documented in classical texts, highlighting its role in moving Qi and Blood in the neck and submandibular region.
