Scarlet fever, also known as scarlatina or streptococcal scarlet fever, is an infectious disease marked by a bright red rash covering most of the body, a high fever, and a sore throat. The condition is caused by the same bacteria responsible for strep throat and can affect individuals of all ages, though it primarily occurs in children. The disease can be serious but is generally treatable with antibiotics.
From a Traditional Chinese Medicine (TCM) perspective, scarlet fever is understood through a holistic lens, considering the imbalance of internal energies rather than focusing solely on the infectious agent.
TCM recognizes that symptoms and diseases, including scarlet fever, are the result of disharmonies within the body's Qi, Yin, Yang, and Blood. Effective treatment in TCM thus depends on accurately identifying the underlying pattern of disharmony.
TCM Patterns for Scarlet Fever
Each pattern represents a distinct underlying imbalance that can cause scarlet fever
Heat and Blood Stagnation in the Lower Burner
Diagnostic signs
Choppy (Se), Full (Shi), Deep (Chen), Rapid (Shu)
The tongue is typically reddish-purple, reflecting the combination of Heat (redness) and Blood Stasis (purple hue). Stasis spots or ecchymoses may be visible on the tongue body, particularly towards the root, which corresponds to the lower body. The sublingual veins are often distended, dark, and tortuous, which is one of the most reliable signs of Blood Stasis. The coating tends to be yellow and dry, reflecting interior Heat consuming fluids. In severe or prolonged cases, the tongue surface may appear dry with prickles, indicating intense Heat scorching the Blood.
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.
