The absence of menstruation during a woman’s reproductive years. It may be primary (menstrual periods never begin by age 15–16) or secondary (menstrual periods stop for 3+ months in someone who previously had regular cycles). Causes can include stress, hormonal imbalance, pregnancy, menopause, excessive exercise, or underlying health conditions.
Traditionally used as an emmenagogue, Blue Cohosh stimulates uterine contractions, eases menstrual cramps, and helps regulate menstruation. It has also been used historically in labor induction but should be approached with caution.
