It is an interesting and meaningful thing to explore the associated networks between cold herb and hot herb within the framework of traditional Chinese medicine because they might be useful for both clinical practice and scientific research. In this study, focused on the fields of disease, pattern/syndrome, symptom, and decoction, we constructed the associated networks between cold herb and hot herb. By analyzing these networks, we found that there is no clear separation between cold herb and hot herb. What's more, they have mutual parts among their networks on disease, pattern/syndrome, symptom, and decoction.
