Taking the Six-flavored Di Huang Pill will not affect the menstrual cycle in the vast majority of cases. If menstruation comes early, it is most often due to endocrine disorders caused by a lack of progesterone, and the luteal gland shrinking in advance of the situation will lead to early menstruation. Taking other medications may lead to early menstruation, such as birth control pills, such as progesterone, etc. Taking medications that invigorate the blood may also lead to early menstruation. In addition, having submucous fibroids or large interstitial fibroids may lead to early onset of menstruation or due to recent poor rest or work stress may also lead to early onset of menstruation for a few days. Combine the clinical history with the gynecological examination and give appropriate treatment if necessary.
