Also known as: Chaste Tree, Chasteberry, Vitex, Agnus-Castus, Vitex agnus-castus
Overview
*Vitex agnus-castus*, commonly known as Chaste Tree or Chasteberry, is a herbal supplement derived from a plant native to the Mediterranean region. Traditionally, it has been employed for various gynecological issues, playing a significant role in managing premenstrual syndrome (PMS), premenstrual dysphoric disorder (PMDD), and cyclic breast pain (mastalgia). The fruit contains bioactive compounds, including flavonoids and diterpenes, which may modulate hormonal balance by interacting with dopaminergic and estrogenic pathways. Its primary applications focus on women's reproductive health, with emerging evidence indicating potential advantages in alleviating menopausal symptoms. Although the research surrounding *Vitex* is moderately mature, it is supported by numerous clinical trials and systematic reviews, though some existing studies display methodological limitations.
Benefits
*Vitex agnus-castus* has documented evidence-based benefits, particularly for women suffering from PMS and PMDD. Systematic reviews indicate its effectiveness in reducing PMS symptoms, with users being 2.57 times more likely to experience symptom remission compared to placebo. Clinical trials have evidenced significant reductions in mastalgia for regular users across multiple menstrual cycles. While support for its role in alleviating menopausal symptoms is less robust, it still suggests potential benefits, especially when combined with other natural products. The most consistently observed benefits relate to moderate to severe PMS symptoms with notable reductions in both physical and psychological distress. Variability in findings is often attributed to differences in methodological quality among studies, thus highlighting the importance of carefully designed trials.
How it works
*Vitex agnus-castus* influences hormonal balance primarily through dopaminergic pathways. Its diterpenes are known to reduce serum prolactin levels, mimicking the action of bromocriptine. Furthermore, the bioactive compounds interact with estrogen receptors, modulating hormonal activity influenced by the hypothalamic-pituitary axis. Collectively, these mechanisms underline the herb's utility in managing conditions associated with hormonal imbalances, particularly in the realm of reproductive health.
Side effects
*Vitex agnus-castus* is generally regarded as safe, with few adverse effects reported. Common gastrointestinal issues, such as nausea and stomach discomfort, may affect over 5% of users, while headache, dizziness, or skin rashes may be observed in 1-5% of individuals. Rare side effects are not consistently documented, and caution is recommended for pregnant and breastfeeding women due to insufficient safety data. Potential interactions can occur with dopamine agonists or antagonists and hormonal contraceptives. Individuals with hormone-sensitive conditions or those using medications that influence dopamine and estrogen levels should consult a healthcare provider prior to use.
Dosage
The recommended dosage for *Vitex agnus-castus* typically ranges from 20-80 mg per day of a standardized extract. Most studies demonstrating efficacy have utilized dosages within this range over 2-6 menstrual cycles. While no definitive upper safe limit is established, dosages exceeding 80 mg daily lack sufficient safety evidence. It is usually advised to take the supplement once daily, commencing at the beginning of the menstrual cycle. The bioavailability of *Vitex* may fluctuate depending on the supplementary form, emphasizing the importance of selecting high-quality standardized extracts for optimal results.
