Anatomical location
On the front of the neck at the level of the cricoid cartilage, immediately behind the posterior border of the sternocleidomastoid muscle.
Traditional actions
Benefits the throat and voice; moves qi through the neck; reduces localized swelling in traditional use.
Recorded indications
Primary: Sore or swollen throat; sudden hoarseness; difficulty swallowing; neck stiffness.
Secondary: Goitre; enlarged cervical nodes described traditionally as scrofula; cough with throat constriction.
How to read this reference
AcuAtlas separates anatomical location, traditional classification, recorded actions, indications, insertion-depth references, and moxibustion notes because these fields answer different study questions. The location statement is the orientation anchor. The classification and actions describe traditional reference categories, while indications summarize how checked educational sources associate the point with established teaching material. They are not a recommendation to select or stimulate the point.
Depth and moxibustion entries are reproduced as bounded reference notes rather than procedural instructions. Individual anatomy, technique, angle, clinical setting, and local professional standards can change what is appropriate. Review the cited documents and supervised training material before using any technical field. The normalized map coordinate is included only to place the point on the matching AcuAtlas body plate; it is not a substitute for palpation or anatomical assessment.

Frequently asked questions
Where is LI-17 located?
On the front of the neck at the level of the cricoid cartilage, immediately behind the posterior border of the sternocleidomastoid muscle.
What reference actions and indications are recorded for LI-17?
Benefits the throat and voice; moves qi through the neck; reduces localized swelling in traditional use. The dataset lists these primary indications: Sore or swollen throat; sudden hoarseness; difficulty swallowing; neck stiffness. Secondary indications are recorded as: Goitre; enlarged cervical nodes described traditionally as scrofula; cough with throat constriction.
Is LI-17 safe during pregnancy?
This dataset does not identify LI-17 as one of its five mandatory pregnancy-caution points. That is not a declaration of safety. Pregnancy-related point selection requires individualized assessment by a qualified clinician.
