During Medieval times Chasteberry was used in monasteries for reducing sexual desire in men and it became known as “Monk’s Pepper’ or “Cloister pepper”.
Vitex Agnus Castus is also used for various minor ailments such as acne, nervousness, headaches, migraine, colds, upset stomach, and even body inflammations.

PREMENSTRUAL SYNDROME – many PMS sufferers exhibit elevated prolactin levels, especially in women experiencing breast pain or fibrocystic breast disease. Studies in PMS sufferers using agnus castus have shown up to ninety percent having improvement or resolution of symptoms. Cramps, breast pain and acne flare ups are often caused by hormonal imbalances during the luteal phase of the menstrual cycle; the phase that occurs after an egg is released from the ovary. Sometimes, the corpus luteum, the yellowish ovarian scar that forms after the egg is released, produces inadequate amounts of oestrogen and progesterone, or excessive amounts of testosterone. Chasteberry stimulates the production of oestrogen and progesterone, while it stops the excessive amounts of testosterone by providing compounds that are very similar to it. In addition to balancing the hormones in these conditions, chasteberry can reduce pain.
Chasteberry may also be helpful in treating menopausal symptoms and treating acne in teenagers (male and female). These benefits may take anything from 10 days to 6 months.
MENSTRUATION DISORDERS – Agnus castus has demonstrated effectiveness in aiding menstruation disorders including; secondary amenorrhoea, metorrhagia, lengthened and shortened cycles, especially when due to progesterone deficiency.
ANTI-MICROBIAL ACTIVITY – Extracts of agnus castus have shown antimicrobial activity against a broad range of organisms including; staphylococcus aureus, salmonella, E. coli, and candida albicans. This may offer additional benefits, as dysbiosis is a common problem and may aggravate existing menstrual disorders.
INFERTILITY – Research suggests that agnus castus can enhance corpus luteal functioning, thus lengthening the luteal phase and normalising progesterone levels often found to be low in infertile women.
The therapeutic effects of chasteberry have primarily been attributed to its indirect effects on various neurotransmitters and hormones. Chasteberry seems to affect dopamine, and possible acetylcholine and opioid receptors
Chasteberry extracts contain multiple constituents that seem to have agonistic effects at pituitary dopamine (D2) receptors when used in higher doses. This dopaminergic activity inhibits basal and thyrotropin-releasing hormone (TRH) – stimulated prolactin release. In women with hyperprolactinemia, chasteberry seems to suppress prolactin release. This may normalize luteal phase defects in the menstrual cycle. In healthy men, chasteberry’s hormonal effect seems to be dose dependant. Lower doses of chasteberry extract of approximately 120mg per day seem to increase prolactin release, higher dosages seem to suppress prolactin release. Chasteberry does not appear to affect testosterone. Traditional use indicate that men wanting to become fathers should avoid taking chasteberry as the seeds may affect sperm production.
The essential oils of chasteberry also seem to have antibacterial and antifungal effects.
