How is the pulse described in a "Cold" pattern in TCM?

In Traditional Chinese Medicine (TCM), a "Cold" pattern is typically characterized by a slow and deep pulse. This pulse presentation reflects the body's response to cold conditions, which tends to slow down physiological processes and can lead to symptoms such as reduced circulation, feeling of coldness, and a general sense of sluggishness.

The slow nature of the pulse indicates a decrease in the body's yang energy, which is often diminished in cold patterns. A deep pulse signifies that the vital energy (Qi) and blood are closer to the interior of the body, reflecting the body's defensive response to internal or external cold influences.

In contrast, other pulse qualities associated with different patterns would present differently. For example, a quick and shallow pulse might indicate heat or yang deficiency, while a fast and strong pulse typically reflects excess heat or agitation. A weak and irregular pulse could suggest exhaustion or deficiency but does not specifically indicate a cold pathology.

Therefore, the description of the pulse as slow and deep aligns with the characteristics observed in a "Cold" pattern in TCM, providing insight into the underlying condition being expressed in the body.
