Afternoon fever, also known as a fever peaking in the afternoon, is a condition characterized by a rise in body temperature later in the day. This type of fever often manifests as a low-grade fever but can escalate in intensity, typically peaking during the late afternoon or early evening. Such fevers can be associated with a variety of underlying conditions, including infections, chronic diseases, or even environmental factors. The body’s natural circadian rhythm can influence these temperature fluctuations, making the fever more noticeable as the day progresses.
Traditional Chinese Medicine (TCM) views afternoon fever as a symptom resulting from various patterns of disharmony within the body. Unlike Western medicine, which may focus on the infection or external cause, TCM emphasizes internal imbalances that predispose an individual to such symptoms. Identifying the correct pattern of disharmony is crucial in TCM for effective treatment. These patterns can include deficiencies, excesses, or invasions of pathogenic factors, each requiring a tailored therapeutic approach.

Liver Yin Deficiency
Diagnostic signs
Fine (Xi), Rapid (Shu), Wiry (Xian)
The tongue is characteristically red, thin, and dry with little or no coating. The sides of the tongue (corresponding to the Liver/Gallbladder area in tongue geography) tend to be redder than the rest of the body. The coating is often completely absent or partially peeled, revealing the red, glossy surface underneath. This mirror-like or geographic coating reflects the depletion of Yin fluids. In milder cases, a thin, scanty, rootless coating may still be visible. Cracks may appear on the tongue surface, particularly in the centre, indicating chronic fluid depletion.

Diagnostic signs
Deep (Chen), Rapid (Shu), Slippery (Hua), Full (Shi)
The tongue is distinctly red, often with prominent prickles or raised papillae (thorns), especially toward the centre and tip, reflecting intense interior heat. The coating is yellow and thick, dry or even rough to the touch, indicating that heat has begun to damage body fluids. In advanced or severe cases, the coating may turn dark yellow, greyish-brown, or even blackish and cracked, with a scorched dry appearance. The tongue body itself may show cracks from fluid depletion.
