There are two major flu seasons in Singapore – May to July, and November to January. These are peak periods of infection of this highly contagious viral disease which attacks the nose, throat and lungs.
In traditional Chinese medicine (TCM), flu is seen as an invasion of the body by external pathogenic factors, brought about by seasonal changes.
According to physician Lee Jin Shun, from Eu Yan Sang TCM Clinic@Bedok and Hougang Mall and Eu Yan Sang TCM Wellness Clinic@PlazaSingapura, the battle between pathogenic factors and the body’s immunity – or qi – results in symptoms like runny nose, cough, dry throat and fever.
The six external pathogenic factors are wind, cold, summer heat, damp, dryness and fire heat.
They arise from changes in the weather, and can occur in combinations.
The two most common ones are the wind-cold flu and the wind-heat flu.
