The exact way to locate the Phase Gate point is to find the intersection of the 6th rib space and the nipple straight down.
It is located on the chest and is usually taken in the supine or sitting position. Since the nipple is flat at the 4th intercostal space, the point can be found by pushing straight down 2 intercostal spaces from this point.
This point can be used to treat pain and fullness in the chest and ribs, as well as breast carbuncles. It can also be used to treat vomiting, bloating, and hiccups caused by liver qi (the liver qi is not working well enough to affect the function of the stomach), and it can also be used to treat illnesses such as retention of urine (not being able to pass urine or urinate).
Zhimen acupoints can be used for both acupuncture and moxibustion; acupuncture should be operated by a professional doctor, and moxibustion should be guided by a doctor.
