Which point is on the flexor aspect of the forearm, 2 cun proximal to Da Ling P-7, between the tendons of palmaris longus and flexor carpi radialis?

• A. PC 6
• B. PC 7
• C. PC 8
• D. SJ 1

Answer: (A)

The key idea is locating points on the Pericardium channel using tendon landmarks and a cun measurement along the forearm. The clue describes a point on the flexor (inner) aspect of the forearm, 2 cun proximal to Da Ling (Pericardium 7) and between the palmaris longus and flexor carpi radialis tendons. That spot is Pericardium 6, also known as Nei Guan. It sits on the same tendon interval as Da Ling but about two finger widths up the forearm, making it a major point for regulating the heart and calming the spirit, as well as addressing nausea, palpitations, and related symptoms. The other options lie in different locations: one is at the wrist itself between those tendons, another is in the palm, and another on the finger, so they don’t match the described forearm position.
