Which acupuncture point is located on the abdomen 2 cun lateral to the umbilicus?

• A. ST 20
• B. ST 25
• C. ST 21
• D. ST 24

Answer: (B)

Understanding how to locate points on the abdomen using the umbilicus as a reference is essential. A cun is a body-width unit used in acupuncture, and “2 cun lateral to the umbilicus” means about two finger-widths away from the midline at the level of the navel.

The point that sits exactly 2 cun to the side of the umbilicus on the abdomen is Tianshu, ST25. This precise placement is why it is the correct choice for the description given. The other points listed are located at different vertical positions along the abdomen and would not match the descriptor of being 2 cun lateral to the umbilicus.
