Eupolyphaga sinensis, also known as the Chinese ground beetle, has been used in Traditional Chinese Medicine (TCM) primarily for its purported abilities to promote blood circulation, remove blood stasis, and relieve pain. In the context of dysmenorrhea (painful menstruation), TCM theory attributes the condition partly to "blood stasis," and thus substances that "invigorate blood" are commonly employed. Historical TCM texts and modern TCM practice include Eupolyphaga sinensis in formulas for conditions involving blood stasis and associated pain, including menstrual pain.

However, scientific studies specifically investigating the efficacy of Eupolyphaga sinensis for dysmenorrhea are limited. Most available evidence is anecdotal or based on traditional usage, with only indirect support from laboratory studies showing its potential effects on blood flow and anti-inflammatory properties. There is a lack of robust clinical trials or systematic reviews that confirm its effectiveness or safety for dysmenorrhea specifically. Therefore, its use for this condition is justified mainly by traditional practice rather than by high-quality scientific validation.
