Deficiency fever colds are generally caused by congenital insufficiencies and bodily weakness, leading to pathogenic yin. It may also result from imbalances between yin and yang, or dysfunction of the spleen. For this type of cold, there is no need to panic, as it can be managed with traditional Chinese medicine. Colds relating to deficiency fever typically manifest with symptoms such as oral sores, dizziness, headaches, irritability, and insomnia. Effective improvement can be achieved by taking medicine that reduces deficiency heat. Alternatively, maintaining a light and simple diet can effectively help improve gastrointestinal digestion. (Medicine should be used under the guidance of a professional doctor.)
