Which point is used in conjunction with Ren-9 to address edema?

Ren-9, also known as Shuigou, is often used in acupuncture to address conditions related to fluid metabolism, making it essential in the treatment of edema. In this context, ST-28, or Shuidao, is particularly effective as it is located near the bladder and plays a crucial role in the regulation of urination and fluid distribution within the body.

By combining Ren-9 with ST-28, practitioners can enhance the body's ability to manage excess fluids, effectively reducing swelling and promoting better kidney function. This pairing is often utilized in clinical practice to address various types of edema, especially those associated with water retention and dysfunction in fluid movement.

Additionally, ST-30, K-9, and P-1 do not specifically target the mechanisms of fluid regulation in the same way as ST-28. While they have their own merits in answering different conditions, ST-28's direct association with bladder function and its role in fluid dynamics make it the optimal choice when paired with Ren-9 to tackle issues related to edema.
