Which is the chosen Lou connecting point for the Kidney?

The chosen Lou connecting point for the Kidney is KID-4, also known as "Guan Yuan." This point is significant in traditional Chinese veterinary medicine (TCVM) as it plays a crucial role in the management of Kidney-related conditions. The Lou connecting points are where the primary meridian connects with its associated pathways, allowing for the communication between the Kidney meridian and other meridians, which is essential for balancing and regulating energy flow in the body.

KID-4 is particularly noted for its ability to influence the Kidney and its relationship with the Heart and Liver, facilitating the flow of Qi and blood. This point can be used therapeutically to address disorders such as Kidney Qi deficiency, low energy, and issues affecting the urinary system.

The other points listed are important in their own right but do not serve as the Lou connecting point for the Kidney. Each point along the Kidney meridian has its specific indications, but KID-4 specifically fulfills the role of linking the Kidney channel with others, making it the correct choice in this context.
