Australian Chasteberry, also known as Vitex agnus-castus or "Holy Berry", has a long-standing history in natural medicine for supporting women’s reproductive health. Grown in the sun-rich regions of Australia, this powerful botanical has been traditionally used to help manage menstrual irregularities, hormonal imbalances, and fertility concerns.

Chasteberry works primarily by influencing the hypothalamic-pituitary-ovarian axis, helping to balance levels of key reproductive hormones such as prolactin and progesterone. This makes it particularly effective in relieving symptoms of premenstrual syndrome (PMS), including breast tenderness, irritability, and dysmenorrhoea. It is also known to assist in regulating menstrual cycles and promoting ovulation, supporting women who are preparing for pregnancy.

For women approaching or experiencing menopause, Chasteberry may alleviate hot flushes, mood swings, and vaginal dryness, supporting a smoother hormonal transition. Its anti-inflammatory and hormone-modulating properties also promote healthy vaginal flora, reduce excessive discharge, and support pH balance—important factors in maintaining vaginal and uterine health.

Backed by both traditional use and modern scientific evidence, Australian Chasteberry is a natural, gentle, and effective ingredient in supporting the full spectrum of female reproductive health—from puberty through to menopause.
