What is the primary designation of SI-3?

The primary designation of SI-3 is indeed as a Lou point. Lou points are significant in Traditional Chinese Veterinary Medicine as they serve as connection points of a meridian, facilitating the flow of Qi and enhancing communication between the primary channel and its branches. Specifically, SI-3 is the Lou point of the Small Intestine channel, contributing to the overall functionality and balance of the channel by addressing issues related to the small intestine and its associated conditions.

The other designations such as connecting points, confluent points, and major channel points have different functions within the context of acupuncture and meridian therapy, which are not applicable to SI-3. For example, connecting points typically relate to the areas where a primary channel connects with a secondary pathway, and confluent points are those that link to the eight extraordinary vessels, which does not apply to SI-3. Understanding the role of Lou points, including SI-3, is essential in diagnosing and treating conditions related to the small intestine, clarifying its importance in the larger framework of acupuncture practice.
