A navel piercing may seem like an adornment, but acupuncture theory strongly suggests that this is not a healthy or safe practice as it has consequences on health.
The problem is that the piercing is creating a semi-permanent obstruction in the flow of a very important energy channel known as the Conception Vessel (CV) or Ren Mai in Chinese. The conception runs from between the legs up the front of the body, ending below the mouth. Take a look at the diagram, notice that the navel is an acupuncture point on the CV8. You may also notice CV8 is a point that one is specifically forbidden to needle.
When an obstruction like a navel piercing is placed in a channel it creates a physical blockage to the flow of the channel. The piercing represents a constant interruption in the energetic field of the body. As you might gather from its name in English, the Conception Vessel is a very important channel in the energetics of the reproductive system.
Consequently, the blockage created by the piercing can possibly lead to problems down the road, particularly with the reproductive system:
Infertility, amenorrhea (no menstrual periods), cervical dysplasia (abnormal cells of the cervix which may lead to cancer), uterine fibroids, endometriosis.
When a woman comes to me for treatment with menstrual complaints infertility it is very common for her to have either a navel piercing or surgical scar along or across the Conception Vessel. When I view a females abdomen area, I notice that do not look after the piercing and it has led to an infection at some point.
People may be well with navel piercings for a few years, but problems may develop down the line. It is possible that most people will never develop symptoms from a navel piercing. But is it worth it? Only you can answer that.
In TICM, we view the navel as our lifeline and second mouth, which is why we do not play with it. When we were in our mother's womb, the placenta which was our lifeline was attached to that navel and which we were fed through.
Other places that should not be pierced are the clitoris or any part of the vaginal area, breasts, nails, fingers, tongue, eyebrows. But at the end of the day, the decision is yours.
