There's an entire school of Chinese Medicine devoted to digestion ("The Earth School").
Literally, we are what we eat... and how well we're able to digest what we eat.
The Earth School believes that the root of all disease can be traced back to the function of the digestive system.
A functioning gut = a healthy and happy human being.
In my practice, I mix an East and West approach. Lab tests can give us an idea of what's working and not working. Chinese herbs and acupuncture can help to repair it.
