Afternoon fever according to Chinese Medicine
The information provided here is not a replacement for a doctor. You shouldn't use it for the purpose of self-diagnosing or self-medicating but rather so you can have a more informed discussion with a professional TCM practitioner.
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 “Yin Deficiency”. As you will see below, we have in record four 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 four "patterns of disharmony" that can cause afternoon fever
In Chinese Medicine afternoon fever is a symptom for 4 patterns that we have on record. Below is a small explanation for each of them with links for more details.
Prepared Rehmannia (Shu Di huang) is the king ingredient for Liu Wei Di Huang Wan, a formula used for Yin Deficiency
Yin Deficiency
Pulse type(s): Rapid (Shu), Empty (Xu)
Tongue coating: Thin white coating
Tongue color: Red
In the case of Yin Deficiency, the body is short in the cooling, moistening and nurturing aspects. This leads to Heat and Dryness accompanied by weakness and lack of strength and resistance. Yin becomes Deficient by over-working, lack of sleep, over-exercising, overindulgence in sex, long-term chronic diseases, internal injury due to the seven emotions, and the over-eating of dry and hot-natured foods.
In addition to afternoon fever, other symptoms associated with Yin Deficiency include insomnia, malar flush and night sweats.
Yin Deficiency is often treated with Liu Wei Di Huang Wan, a herbal formula made of 6 herbs (including Prepared Rehmannia - Shu Di huang - as a key herb). Liu Wei 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: "Nutritive tonic for the Liver and Kidney Yin Essence (nourishes the parasympathetic nervous system)".

Pulse type(s): Rapid (Shu), Empty (Xu), Floating (Fu)
Tongue coating: Complete absence of coating
Tongue color: Red
Tongue shape: Cracked
Kidney Yin Deficiency causes false Heat symptoms, such as night sweats, thirst and five palm heat. These signs are from a depletion of Body Fluids and Essence. It can be caused by prolonged overwork, excessive sexual activity, chronic long term illnesses, consumption of Body Fluids by Heat, prolonged blood loss, overdosage of Kidney Yang tonics herbs, smoking and Kidney depleting foods such as coffee, alcohol, sugar, and fruit juices.
In addition to afternoon fever, other symptoms associated with Kidney Yin Deficiency include insomnia, malar flush and night sweats.
From a Western Medicine standpoint Kidney Yin Deficiency is associated with health issues such as Menopausal Syndrome, Prolonged Periods or Irregular Menstruation.

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).

Bright Yang Fire in Stomach and Intestines
