Which of the following signs correlates with Stomach Fire?

Thirst with a desire to drink cold liquids is a classic sign of Stomach Fire in Traditional Chinese Medicine (TCM). When there is an excess of heat (or "fire") in the stomach, it can lead to symptoms such as excessive thirst and a preference for cold liquids, as the body instinctively seeks to cool down the internal heat. This thirst is often intense and may be accompanied by a dry mouth.

In the context of Stomach Fire, the heat affects the normal function of the stomach, leading to a disruption in digestion and potentially causing symptoms like irritation or inflammation. This is why the presence of intense thirst can be indicative of an underlying excess heat condition rather than a deficiency or cold condition.

Other signs listed, such as feeling of heaviness, cold limbs, and sour regurgitation, are associated with different patterns in TCM, like Spleen deficiency or phlegm, rather than Stomach Fire specifically. Understanding these distinctions helps in diagnosing and treating various conditions effectively.
