Chasteberry (also known as Vitex agnus-castus, vitex, chaste tree, Abraham’s balm, lilac chastetree or monk’s pepper isolated) is a powerful herbal remedy that has been used for centuries to support women’s reproductive health. Often referred to as the “female herb,” chasteberry has gained popularity in recent years for its potential to balance hormones, alleviate PMS symptoms, and regulate menstrual cycles.
In this blog post, we’ll explore everything you need to know about chasteberry—what it is, its nutritional content, health benefits, possible side effects, how to take it, and who should or shouldn’t use it.
What is Chasteberry?
Chasteberry, or Vitex agnus-castus, is a small fruit from the chaste tree native to the Mediterranean region and Central Asia. The plant produces purple flowers and dark brown berries about the size of peppercorns. Historically, it was believed to reduce sexual desire—hence the name “chaste” berry. Monks in the Middle Ages used it for this purpose, giving rise to its nickname, “monk’s pepper.”
But beyond its folklore, chasteberry has been traditionally used to treat various hormonal imbalances, especially in women. It doesn’t contain hormones itself but is believed to influence the body’s hormone production, particularly by supporting the pituitary gland. The primary active compounds include flavonoids, iridoid glycosides, and essential oils, which contribute to its medicinal properties.

Chasteberry is available in several forms:
- Capsules or tablets (standardized extract)

- Teas
- Powdered fruit
- Liquid extracts
Capsules and standardized tablets are the most convenient and commonly used form. Tinctures and teas may provide gentler effects and are preferred in traditional herbalism.

The dosage depends on the form and purpose of use:
- Standardized extract: 20–40 mg per day (containing 0.6% agnuside)
- Dried fruit: 150–250 mg per day
- Tincture: 2–5 mL taken once or twice daily
Always start with the lowest effective dose and consult your doctor before beginning any new supplement, especially if you’re using hormonal medications.
Potential Drug Interactions
Chasteberry may interact with certain medications and conditions:
- Hormonal contraceptives: It may interfere with birth control pills.
- Dopamine agonists: It affects dopamine pathways and may enhance or block the effect of these drugs.
- Hormone replacement therapy (HRT): Interaction is possible.
- Antipsychotic medications: May have additive dopaminergic effects.
- Parkinson’s medications: Should be avoided unless advised by a doctor.
If you’re on any hormone-related medication, it’s best to avoid chasteberry unless advised otherwise.
Tips for Consuming Chasteberry
- Consistency is key: It may take 8–12 weeks to see noticeable effects.

How Much Chasteberry Can You Take in a Day?
For most adults, 20 to 40 mg per day of standardized extract is considered safe. Taking more than the recommended dose does not increase benefits and may raise the risk of side effects.
Those using tinctures or dried berries should follow the instructions on the product label or a healthcare provider’s guidance.
Best Time to Take Chasteberry
Taking chasteberry in the morning is ideal, especially on an empty stomach, as it aligns with the body’s hormonal rhythms. If you experience nausea, taking it after breakfast can help.
