Dark clots in menstrual blood according to Chinese Medicine

TCM Education Center > Symptoms list > Dark clots in menstrual blood

Dark clots in 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 dark clots in 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 dark clots in menstrual blood is often associated with scanty periods, painful period and abdominal pain in the pattern “Blood Stagnation”. As you will see below, we have in record five patterns that can cause dark clots in menstrual blood.

Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of dark clots in menstrual blood 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 dark clots in menstrual blood.
