Menstrual pain attributable to cold-damp damaging the thoroughfare (chōng) and controlling (rèn) vessels and the uterus, congealing the blood and blocking its downward movement to the uterus. Congealing cold-damp menstrual pain is characterized by cold or gripping pain in the lower abdomen that likes warmth, and dark clotted inhibited flow.
Medicinal therapy: Use formulas such as Lesser Abdomen Stasis-Expelling Decoction (少腹逐瘀汤shào fù zhú yū tāng) or a decoction of leonurus (Leonuri Herba, 益母草yì mǔ cǎo), dried ginger (Zingiberis Rhizoma, 干姜gān jiāng), and pepper (Piperis Fructus, 胡椒hú jiāo). Vacuity cold with thin pale flow and dull abdominal pain that likes warmth is treated by warming the channels and supplementing vacuity with formulas such as Minor Provisioning Brew (小营煎xiǎo yíng jiān) and Chinese Angelica Center-Fortifying Decoction (当归建中汤dāng guī jiàn zhōng tāng).
