Chasteberry, scientifically known as Vitex agnus-castus, is a small fruit from the Mediterranean region. Historically used to balance hormones, it is gaining recognition for its potential in alleviating premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD).
Chasteberry appears to act on the pituitary gland, reducing prolactin secretion and promoting balanced levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
This hormonal shift may increase progesterone and decrease estrogen, which is believed to ease PMS symptoms like breast tenderness, irritability, and mood swings.
Several clinical trials have demonstrated that chasteberry extract significantly reduces PMS severity compared to placebo or vitamin B6.
A meta-analysis reported that women using standardized Vitex preparations were 2.6 times more likely to experience symptom relief (NUNM). Many trials also compared Vitex to fluoxetine and found it similarly effective, often with fewer side effects.
Most benefits become apparent after two to three menstrual cycles, underscoring the need for consistent use.
Vitex is ideal for individuals experiencing cyclical PMS symptoms, including:
It is not a quick fix—Vitex requires 8–12 weeks to show noticeable improvement. It should be avoided during pregnancy, breastfeeding, or if taking dopamine-affecting medications or hormone therapy.
Chasteberry is generally safe. Some users report mild gastrointestinal upset, headache, or skin rash. However, serious side effects are rare and usually resolve after discontinuation.
