Chasteberry Effective in Asian Women

The beneficial effects of chasteberry on the symptoms of premenstrual syndrome, previously shown in Western populations, have been confirmed in an Asian population of women. Known to positively mediate the female hormonal system, chasteberry is effective in the treatment of moderate to severe premenstrual syndrome.

The health benefits of chasteberry on womens health have been known for some time. Chasteberry has been shown to be an effective way to reduce the symptoms of premenstrual syndrome, most likely through its effect on hormonal control. In several successful studies conducted in Western populations, chasteberry significantly diminishes the symptoms of premenstrual syndrome [1-3].

To date, these studies had been conducted in western populations and it was previously unknown whether the same benefits would be achieved in an Asian population. Asian women enjoy a substantially different diet than those of their western sisters, and therefore have a dissimilar nutritional intake. Traditionally, the Asian diet has consisted of a much higher amount of soy products which may influence the hormonal regulation of women.

A recent study investigating the effects of chasteberry in a Chinese population confirmed that chasteberry is beneficial across racial groups in the management and treatment of premenstrual symptoms [4]. In the study involving over 200 Chinese women, it was found that chasteberry significantly improved self-reported symptoms of premenstrual syndrome associated with mood, water retention, food and pain, compared to placebo. Using the internationally validated premenstrual syndrome diary (PMSD), a self-assessment symptom rating scale, chasteberry significantly lowered the PMSD score from 29.23 at baseline (0 months) to 6.41 (3 months). These results were achieved after 3 months of treatment with chasteberry at 40mg per day. As expected from other similar studies, there was a significant placebo effect of 50%, although chasteberry significantly reduced PMSD scores compared to placebo. There were also no significant adverse events notable in the treatment group compared to placebo.

Chasteberry represents an effective clinically tested safe natural therapeutic for the management and treatment of the symptoms of premenstrual syndrome for all women. The latest study conducted by He et al. confirms that chasteberry is effective for the treatment of premenstrual syndrome across racial groups in different settings.
