Both internal heat and external cold can exist at the same time. For example, the patients with yin deficiency can also have cold or wind cold caused by external factors. You can choose to take some Chinese medicine orally to recuperate. Patients can first differentiate their symptoms and see what the main symptoms are. For example, some patients may have hot flashes in their palms, night sweats and other phenomena due to the deficiency heat, but the cold symptoms are not obvious, so they can first choose to treat the deficiency heat. If there is exogenous wind cold on the basis of the deficiency heat, and the wind cold symptoms are relatively severe, they can also choose to treat the wind cold first, So the order of treatment is different.
