What is the correct needle direction for puncturing the lung when needling HE-1?

When needling HE-1, which is located at the medial side of the upper arm, the correct needle direction is medially. This technique is crucial not only to achieve the desired therapeutic effect but also to ensure safety. Puncturing the lung is a risk when needling near the axillary area and the medial aspect of the arm due to the proximity of the lung and significant vascular structures.

Medial insertion aligns with the anatomical structure of the area, helping the practitioner avoid injury to the lung tissue while still targeting the appropriate acupoint optimizing the treatment’s efficacy. In contrast, lateral, superior, or inferior insertion could lead to an increased risk of puncturing the lung or surrounding structures, positions that may compromise both safety and effectiveness. Proper technique and needle direction are essential for maintaining patient safety and achieving the goals of TCM treatments.
