Western doctors have known that the pains on the pit of stomach is gastroesophageal reflux disease (GERD) and the cause is from the stomach and gastroesophageal sphincter muscle. Recently they come to think the heartburn could be caused by the GERD.
In my opinion, this is one of development in western medicine to think the relation between heart and stomach though the cause and the result are reversed.
Now I would like to point out what they misunderstand about the relation between GERD and heart.
The ancient doctors of east asia called the pit of stomach as heart- below not as stomach or esophagus though they had already known about the anatomical structure. Why do you think they did?
They wanted to express the cause of GERD is not the digestional disease but heart disease, especially psychological heart disease.
The patholgy is as follows.
Psychological stimus -> Disorder of heart ( Backgrounded of weak heart and weak stomach but not weak pancreas or spleen) -> To keep danger level constantly to protect heart and so to stop digesting that necessarily loosen danger level. -> To make GERD.
So the herbal treatment for GERD is focused to heart. The herbs are mainly composed of those for fever and humidity of heart.
The treatment cases for GERD shall be omitted because it is common disease to record. If you want to read the case, No.2 of this treatment cases "Chronical Stomach Pain of Hepatitis B carrier" shall be recommended.
