Muscle weakness 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 muscle weakness 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 muscle weakness is often associated with scanty periods, blurred vision and dizziness in the pattern “Liver Blood Deficiency”. As you will see below, we have in record two patterns that can cause muscle weakness.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of muscle weakness we’ve identified two herbal formulas that may help treat patterns behind the symptom.
We’ve also selected below the two medicinal herbs that we think are most likely to help treat muscle weakness.
The two "patterns of disharmony" that can cause muscle weakness
In Chinese Medicine muscle weakness is a symptom for 2 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 Blood Deficiency
Pulse type(s): Choppy (Se), Fine (Xi)
Tongue color: Pale
The Liver stores Blood, that is the reason any Blood Deficiency often involves the Liver. This pattern has an impact on areas the Liver relates to, such as the tendons, eyes, nails and menstruation. It arises from the same causes of general Blood Deficiency, such as poor diet, hemorrhages or Kidney Qi or Essence Deficiency.
In addition to muscle weakness, other symptoms associated with Liver Blood Deficiency include scanty periods, blurred vision and dizziness.
Liver Blood Deficiency is often treated with Si Wu Tang, a herbal formula made of 4 herbs (including Prepared Rehmannia - Shu Di huang - as a key herb). Si Wu Tang belongs to the category of "formulas that tonify blood", which might be why it is often recommended for this pattern. Its main action as a formula is: "Restores and nourishes Blood".

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 muscle weakness, other symptoms associated with Liver Yin Deficiency include scanty periods, blurred vision and dizziness.
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".
