Thin menstrual blood according to Chinese Medicine

TCM Education Center > Symptoms list > Thin menstrual blood

Thin menstrual blood 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 thin menstrual blood 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 thin menstrual blood is often associated with dizziness, pale menstrual blood and lower back pain in the pattern “Spleen or Kidney Qi Deficiency”.

Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of thin menstrual blood we’ve identified two 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 thin menstrual blood.
