Study: herbal medicine in PCOS improves symptom management

Researchers looked into herbal medicine plus lifestyle changes versus just lifestyle changes alone when it came to reducing symptoms of polycystic ovarian syndrome (PCOS).

The herbs examined were tribulus, peony, liquorice, cinnamon and St John’s wort, all used regularly by herbalists for irregular periods, sugar cravings, anxiety and mood interferences in women.

These herbs are known for their various effects in women with PCOS, for example tribulus can improve ovulation rates, peony and liquorice reduce androgens, cinnamon is known to reduce insulin resistance, and St John’s wort can reduce anxiety and depression. The study has validated the use of these herbs when treating PCOS.

The Study​1​ on herbal medicine in PCOS

The randomised controlled trial in 122 women with PCOS ran across three months. All women taking part were required to adhere to an exercise regime and changes to their diet, but half were also taking herbal medicines.

  • Tribulus was taken from Day 5 of the menstrual cycle (or Day 7 of the trial if the women were not menstruating), for 10 days.
  • A tablet containing peony, liquorice, cinnamon and St John’s wort was taken every day for the duration of the trial.
  • The exercise regime include 90 minutes per week of aerobic exercise and 60 minutes per week of resistance training.
  • Diet modifications included including low glycaemic index carbohydrates and nutrient-dense foods, with attention to caloric intake, with the goal to achieve weight loss or prevent weight gain.

What did we learn about herbal medicine for PCOS?

The herbal medicine treatment group had significant improvements in all areas, including more regular periods, managing weight, regulating insulin levels, stabilising luteinising hormone, managing blood pressure, and reducing anxiety, stress, and depression.

There were improvements in pregnancy rates amongst those trying to conceive, and improvements in quality of life were reported.

Those taking the herbal medicine experienced:

  • A 33 per cent reduction in cycle length (time between periods)
  • Weight loss of on average 3kg, and 3cm circumference from their waists
  • 40 per cent lower insulin levels

There were no major differences in the amount of exercise and diet choices made by the women across all groups, which showed up the powerful role of the herbs in managing PCOS symptoms.

Warning: St John’s Wort may increase the metabolism of prescription medications and reduce their effect, or interfere with some antidepressants. Please check with your doctor or herbalist before starting herbal medicine on your own.
