Influenza, also known as the flu, is primarily caused by the invasion of the respiratory tract by the influenza virus, resulting in symptoms such as cough, sore throat, and fever. In traditional Chinese medicine, influenza is categorized as wind-heat lung heat disease or phlegm-heat obstructing the lungs syndrome. It is generally recommended that patients with the flu should consume light, heat-clearing, fire-reducing, and anti-inflammatory foods. It is best to avoid overly oily, salty, or sweet foods. Additionally, consuming foods primarily made from ingredients like dandelion, Andrographis paniculata, and wild chrysanthemum can clear heat, detoxify, reduce inflammation, and have antibacterial effects, providing some supportive benefits for flu treatment.
