Which meridian does NOT meet at REN-24 (Cheng Jiang)?

REN-24, known as Cheng Jiang, is a significant point located at the center of the mentolabial groove. This point is particularly important as it connects with several meridians, facilitating the regulation of facial and oral functions, among other aspects.

The Du Mai, or Governing Vessel, intersects at REN-24, as it travels along the midline of the body, influencing the head and neck area. The Large Intestine meridian also meets at this point, given its trajectory which goes upwards towards the face. Similarly, the Stomach meridian is linked to REN-24 as it governs functions associated with digestion and faces the mouth area.

In contrast, the Kidney meridian does not intersect with REN-24. The Kidney meridian travels along the inner leg and torso, primarily associated with reproductive and urinary functions, and it does not extend to the facial region where Cheng Jiang is located. This distinction is key in understanding the specific pathways of the meridians and their respective relationships to various acupuncture points.
