What is a defining symptom of Blood Stasis in the stomach?

In the context of Traditional Chinese Medicine, Blood Stasis refers to a condition where the blood flow is impeded, leading to a variety of symptoms depending on the affected organ. When considering Blood Stasis in the stomach, a defining symptom is the vomiting of dark blood. This symptom indicates a more severe and acute condition associated with stagnation and possible internal bleeding. The dark color suggests the presence of older blood that is no longer in circulation and may signify a serious underlying issue.

In cases of Blood Stasis in the stomach, other symptoms can be present, such as pain, but they usually involve signs of stagnation rather than active bleeding. While dull epigastric pain can potentially occur in Blood Stasis, it is not as defining as the vomiting of dark blood because pain can result from various other conditions as well. A burning sensation in the epigastrium typically relates to heat conditions rather than blood stasis, and shortness of breath is more indicative of respiratory or lung issues rather than a gastrointestinal problem. Thus, the vomiting of dark blood distinctly highlights the pathology of Blood Stasis within the stomach, making it the most defining symptom in this context.
