The Chengshan (BL-57) acupressure point, also known as Urinary Bladder 57 or BL-57, is a powerful and commonly used point in traditional Chinese medicine (TCM), particularly for treating lower body conditions. Here's a detailed breakdown:
📍 Location
-
Chengshan (BL-57) is located in the lower leg, specifically:
-
In the posterior midline of the leg, between the calf muscle (gastrocnemius).
-
It lies about midway between the popliteal crease (behind the knee) and the heel, in the depression formed below the muscle belly when the leg is stretched or toes are pointed upward.
-
👉 How to find it:
-
Sit with your leg straight or stand with the foot slightly flexed.
-
Locate the midpoint between the crease of the back of your knee and the bottom of your heel.
-
Press into the groove between the two large muscles of your calf.
