I regularly advise my patients to be mindful of how they are going about getting piercings and tattoos–there are factors such as placement that will impact your health negatively or positively; for example in TCM we intentionally burn mugwort on specific acupuncture points in order to cause a small burn wound and scar. This is done with a specific, established intent based on a diagnosis and treatment method.
Conversely, if you pierce your tongue where most people do–right in center– you are impacting the Stomach organ system and causing scarring in an undesirable area that actually harms the flow of qi through the central digestive organs. You are also causing a wound that regularly breaks open or gets inflamed, and guess what? That infection and inflammation ends up in the rest of your GI tract as well.
When I was 19 years old I had my tongue pierced because I didn’t know better. It was also 1999 and piercings were just becoming fashionable again. There were other factors involved but over the subsequent ten years of my life I had severe GI issues that made life miserable, and it wasn’t until I removed my piercing that it slowly began to recover.
