Jiachengjiang is a local point primarily used for conditions affecting the mouth and jaw, such as facial paralysis, trigeminal neuralgia, and dental pain. Its classical indication for acute epidemic jaundice suggests a capacity to clear severe heat and toxins, although this usage is rare today. It is often used in conjunction with other local and distal points for facial disorders.
