Anguish in the heart

A feeling of heat and clamoring stomach. It is called anguish in the heart because it is located in the pit of the stomach just below, conventionally often referred to as heart in Chinese medicine. It arises when, after exterior patterns have been treated by an inappropriate form of sweating or have been wrongly treated by draining-precipitation, the external evil enters the interior and lodges in the chest and diaphragm, thus harassing the stomach. In modern clinical practice, it is seen in febrile disease or in acute gastroenteritis.
