Influenza, commonly known as the flu, is a respiratory illness marked by symptoms like high fever, cough, sore throat, and muscle aches. It's a widespread condition known for its rapid spread and seasonal peaks. Variations in severity make influenza a public health concern, with potential complications in vulnerable groups.
Traditional Chinese Medicine (TCM) perceives influenza beyond a viral infection. In TCM, it's seen as an imbalance of the body's Qi (vital energy) due to external pathogenic factors. The diagnosis and treatment in TCM revolve around identifying and correcting this imbalance.
Commonly, influenza is attributed to external invasions like Wind-Cold or Wind-Heat, which disrupt the body's Qi harmony, leading to flu symptoms. Treatment approaches, including herbal remedies, acupuncture, and lifestyle adjustments, are tailored to the specific pattern of disharmony in each individual.
TCM Patterns for Influenza
Each pattern represents a distinct underlying imbalance that can cause influenza
Heat in Yang brightness Organs
Diagnostic signs
Full (Shi)
Yang Excess
Diagnostic signs
Rapid (Shu), Full (Shi), Overflowing (Hong)
The tongue is characteristically red with a dry, yellow coating that may be thick. Red prickles (raised papillae) may appear on the tongue body, especially in the centre, reflecting intense internal Heat. The tongue is notably dry due to Body Fluids being consumed by the excess Heat. In some cases, the tip of the tongue may be especially red, indicating Heat affecting the Heart and disturbing the spirit.
Exterior Cold invading with Interior Heat from Stagnation
Diagnostic signs
Floating (Fu), Tight (Jin), Rapid (Shu)
The tongue in this pattern characteristically shows a red body (reflecting interior heat) with a thin white coating that may be turning yellow, especially at the root or centre. The edges of the tongue are often redder than the centre, indicating heat constrained by the exterior cold. In early stages the coating may still be predominantly white and slightly moist from the exterior cold invasion, but as interior heat develops, yellow patches appear. The coating is typically rooted, indicating that the body's righteous Qi is still strong and actively fighting the pathogen.
Phlegm-Fluids in the limbs
Diagnostic signs
Tight (Jin), Wiry (Xian), Floating (Fu)
The tongue is typically pale or slightly pale-red with a swollen body, often showing teeth marks along the edges. The coating is white and slippery or moist, reflecting the accumulation of cold fluid. In presentations with internal Heat (Da Qing Long Tang pattern), the coat may have a faint yellowish tinge. The overall impression is of excess moisture: the tongue surface may appear wet or glossy.
