Organic Chaste Tree Extract
Also known as: Chaste Tree, Chasteberry, Monk's Pepper, Vitex agnus-castus
Overview
Vitex agnus-castus, commonly referred to as Chaste Tree or Chasteberry, is a flowering plant native to the Mediterranean region. Its fruit is primarily used in herbal medicine to address female reproductive health issues, notably premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). The plant contains bioactive compounds, including flavonoids and terpenoids, which contribute to its therapeutic effects. Research indicates moderate to high quality supporting its efficacy in alleviating PMS symptoms and balancing hormones. Standardized forms of extracts are used to ensure both potency and bioactivity, making it a popular choice in herbal treatments for women’s health.
Benefits
Vitex agnus-castus is recognized for its various evidence-based benefits, predominantly in alleviating PMS symptoms. Meta-analyses suggest that women utilizing this extract are more than 2.5 times likely to experience symptom remission compared to those on placebo, with notable reductions in PMS discomfort. The effects of Vitex rival those of pharmaceuticals like fluoxetine and oral contraceptives. Furthermore, it exhibits anti-inflammatory properties and antimicrobial activity against specific pathogens. The main beneficiaries include women struggling with PMS/PMDD, who often report significant improvements across menstrual cycles.
How it works
The action of Vitex agnus-castus involves modulation of the dopaminergic system, which influences prolactin levels, subsequently aiding in menstrual cycle regulation. It binds to estrogen receptors, contributing to hormonal balance and displays inhibitory action on lipoxygenase enzymes, implicating its role in inflammation modulation. Additionally, interactions with opioid receptors may enhance its efficacy in addressing mood disturbances and discomfort associated with menstrual cycles.
Side effects
Vitex agnus-castus is largely considered safe, with adverse effects being mild and infrequent in clinical studies. Common side effects reported in more than 5% of users include gastrointestinal disturbances such as nausea and stomach pain. Uncommon effects (1-5% occurrence) may involve headaches and skin rashes, while rare side effects (less than 1%) are not consistently documented. Caution is warranted for individuals on dopamine antagonists or hormonal therapies, as potential interactions may arise. Pregnant and breastfeeding women are advised against its use due to lack of sufficient safety data. Women with hormone-sensitive cancers should also approach its use with caution due to its possible estrogenic activity.
Dosage
For standardized extracts of Vitex agnus-castus, the recommended dosage typically ranges from 20-40 mg per day. While minimum effective doses have not been conclusively established, this range is commonly prescribed. Dosing is generally once daily, and ethanol extracts are preferred for their proven efficacy. No upper safety limit has been officially defined; however, doses exceeding 40 mg per day are less frequently researched, suggesting diminishing additional benefits at higher levels. Variability in absorption may occur depending on the extraction method, underscoring the importance of standardized products.
