The absence of menstruation is categorized into physiological and pathological, physiological does not need to take medication, while pathological needs to choose medication according to the type of evidence, such as Dazhongyuan Decoction, Diaphragm Downward Stasis Expelling Soup, and so on. The absence of menstruation may be due to pregnancy, breastfeeding or menopause, in which case no measures need to be taken. However, if the above possibilities are ruled out, then it is considered that the absence of menstruation is pathologic, mostly amenorrhea, which may be related to kidney deficiency, qi stagnation and blood stasis (because of blood stasis due to the lack of qi circulation), and cold congealing and blood stasis. 1. Kidney deficiency: symptoms such as dizziness and tinnitus, lumbar and knee soreness (a feeling of soreness and weakness in the lumbar region and knees), and frequent urination can be treated with proprietary Chinese medicines or formulae such as Dajian Yuan Decoction. 2. Qi stagnation and blood stasis: symptoms such as depression, irritability, fullness in the chest and ribs, sighing, dark purple tongue or petechiae, etc. can be treated with proprietary Chinese medicines or formulas such as Diaphragmatic Stasis Expelling Tang. 3. Cold-congealed blood stasis: symptoms such as coldness (coldness of the body), cold limbs, blue and white color, dark purple tongue, white moss, etc. can be treated with proprietary Chinese medicines or formulas such as Warming the Menstruation Soup. If you need medication, please go to a regular hospital for treatment under the guidance of a doctor’s diagnosis, and do not take medication on your own to avoid delaying your condition.
