Does chamomile reduce premenstrual syndrome symptoms?

Yes, chamomile was significantly more effective than placebo at reducing physical and psychological PMS symptoms. We can be fairly confident because this was a double-blind randomized controlled trial with 118 women.

Moderate study design 118 university students at Guilan University of Medical Sciences in Iran with moderate to severe PMS

What they did

Double-blind randomized trial with 118 students with moderate to severe PMS. Chamomile group took 250 mg powder 3 times daily from 7 days before menstruation until bleeding began. Placebo group took identical capsules. Treatment lasted one cycle. Symptoms measured before and after with standardized screening tool.

What they found

Both the chamomile and placebo groups showed decreases in PMS symptom severity after one cycle of treatment. However, chamomile was more effective than placebo at reducing the severity of physical symptoms, psychological symptoms, and overall PMS symptoms.

What it means for you

Chamomile appears to be helpful for reducing PMS symptoms beyond just a placebo effect. The study was reasonably sized with 118 women and well-designed as a double-blind trial. The main limitations are that treatment was only tracked for one cycle and all participants were university students at one institution in Iran.
