The treatment of premenstrual syndrome with preparations of Vitex agnus castus: a systematic review and meta-analysis

Conclusion: Although meta-analysis shows a large pooled effect of Vitex agnus castus in placebo-controlled trials, the high risk of bias, high heterogeneity, and risk of publication bias of the included studies preclude a definitive conclusion. The pooled treatment effects should be viewed as merely explorative and, at best, overestimating the real treatment effect of Vitex agnus castus for premenstrual syndrome symptoms.

Vitex agnus-castus extracts for female reproductive disorders: a systematic review of clinical trials

Conclusion: Limitations include small sample sizes in some studies, heterogeneity of conditions being treated, and a range of reference treatments.Despite some methodological limitations, the results from randomised, controlled trials to date suggest benefits for Vitex extracts in the treatment of premenstrual syndrome, premenstrual dysphoric disorder and latent hyperprolactinaemia. Further research is recommended, and greater transparency in reporting for future trials.

Vitex agnus castus for premenstrual syndrome and premenstrual dysphoric disorder: a systematic review

Conclusion: Main limitations were differences in definition of diagnostic criteria, the instruments used as main outcome measures, and different preparations of VAC extracts limit the comparison of results between studies. In conclusion, the RCTs using VAC for treatment of PMS/PMDD suggested that the VAC extract is a safe and efficacious alternative to be considered for the treatment of PMS/PMDD symptoms.
