Alternating fever and chills according to Chinese Medicine

Home > Symptoms list > Alternating fever and chills

Alternating fever and chills 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 alternating fever and chills 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 alternating fever and chills is often associated with generalized body pain, absence of sweating and wheezing in the pattern “Phlegm-Fluids above the diaphragm”. As you will see below, we have in record three patterns that can cause alternating fever and chills.

Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of alternating fever and chills we’ve identified four 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 alternating fever and chills.

The three "patterns of disharmony" that can cause alternating fever and chills

In Chinese Medicine alternating fever and chills is a symptom for 3 patterns that we have on record. Below is a small explanation for each of them with links for more details.

Liver Qi Stagnation

Pulse type(s): Wiry (Xian)

When Liver Qi does not flow smoothly or regularly, it becomes Stagnant and in Excess. This leads to Heat accumulating in the Liver. The feeling of ‘Distension’ (zhang 胀) is the main symptom of Liver Qi Stagnation.

In addition to alternating fever and chills, other symptoms associated with Liver Qi Stagnation include irritability, flank pain and stifling sensation in the chest causing one to have deep sighs.

From a Western Medicine standpoint Liver Qi Stagnation is associated with health issues such as Low Breast Milk Supply, Mastitis or Breast Engorgement.

Liver Qi Stagnation is often treated with Xiao Yao San, a herbal formula made of 6 herbs (including Bupleurum Roots - Chai Hu - as a key herb). Xiao Yao San belongs to the category of "formulas that harmonize liver-spleen", which might be why it is often recommended for this pattern.
