Afternoon fever according to Chinese Medicine

Home > Symptoms list > Afternoon fever

Afternoon fever can be the consequence of several so-called “patterns of disharmony” in Chinese Medicine.

Chinese Medicine sees the body as a system, not a sum of isolated parts. A "pattern" is when the system's harmony is disrupted, leading to symptoms or signs that something is wrong (like afternoon fever here). It is similar to the concept of disease in Western Medicine but not quite: a Western disease can often be explained by several Chinese patterns and vice-versa.

A pattern often manifests itself in a combination of symptoms that, at first glance, do not seem necessarily related to each others. For instance here afternoon fever is often associated with insomnia, malar flush and night sweats in the pattern “Liver Yin Deficiency”. As you will see below, we have in record five patterns that can cause afternoon fever.

Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of afternoon fever we’ve identified five herbal formulas that may help treat patterns behind the symptom.

We’ve also selected below the five medicinal herbs that we think are most likely to help treat afternoon fever.

The five "patterns of disharmony" that can cause afternoon fever

In Chinese Medicine afternoon fever is a symptom for 5 patterns that we have on record. Below is a small explanation for each of them with links for more details.

The Liver is a so-called "Zang" Organ. Learn more about the Liver in Chinese Medicine

Liver Yin Deficiency

Pulse type(s): Rapid (Shu), Empty (Xu), Wiry (Xian), Floating (Fu)

Tongue coating: Complete absence of coating

Tongue color: Red points on the sides

This is a type of empty Fire pattern arising out of Liver Blood Deficiency or Kidney Yin Deficiency. It shares similar symptoms as Liver Blood Deficiency, but with extra signs of Dryness and Yin-Deficient Heat. It can be caused by excessive activity, overwork, 'burning the candle at both ends' without sufficient rest, and poor and irregular diet.

In addition to afternoon fever, other symptoms associated with Liver Yin Deficiency include insomnia, malar flush and night sweats.

Liver Yin Deficiency is often treated with Qi Ju Di Huang Wan, a herbal formula made of 8 herbs (including Prepared Rehmannia - Shu Di huang - as a key herb). Qi Ju Di Huang Wan belongs to the category of "formulas that nourish yin and tonify", which might be why it is often recommended for this pattern. Its main action as a formula is: "Nourishes Kidney and Liver Yin".
