Introduction

The tongue coating color of patients with influenza A is commonly white or yellow. It is important to develop good living habits, ensure adequate sleep, and aim to maintain 7-8 hours of high-quality sleep each night to allow the body to rest sufficiently. A balanced diet with adequate intake of various nutrients, along with increased consumption of fresh fruits and vegetables rich in vitamin C, can help enhance the body's resistance to disease.

Generally speaking, swine flu refers to influenza A. The tongue coating color of patients with influenza A is usually white or yellow. The specific analysis is as follows:

In the early stage of influenza A, the patient's tongue coating is often thin and white. At this point, the virus has just invaded the body and has not deeply penetrated, so the disease location is relatively superficial. As a result, the tongue coating shows a slight change based on the normal tongue appearance, presenting as thin white coating. As the disease progresses and heat pathogens gradually intensify within the body, the tongue coating may change from thin white to thin yellow, and may further develop into thick yellow coating. The heat pathogens cause the tongue coating to turn yellow, and as the pathogenic factors increase and the condition worsens, the tongue coating becomes thicker. Additionally, if the patient's constitution is weak or the illness persists for a prolonged period, affecting the function of the spleen and stomach and causing internal accumulation of dampness, the tongue coating may become white greasy or yellow greasy.

Maintain good lifestyle habits in daily life, ensure sufficient sleep, and aim for 7-8 hours of high-quality sleep each night to allow the body to fully rest and enhance immunity. Eat a balanced diet, ensure intake of various nutrients, and consume more fresh fruits and vegetables rich in vitamin C, such as oranges and broccoli, to help improve the body's disease resistance.

Can an 11-month-old baby take oseltamivir phosphate granules?

In general, whether an 11-month-old infant can take oseltamivir phosphate granules depends on the specific circumstances.
