Agnus Castus Extract (Chaste Berry)

What is Chaste Berry?

Chaste Tree (Vitex agnus-castus) is a shrub native to the Mediterranean, and its berries have been used in traditional European herbal practice for centuries. Its name comes from an old belief that it dampened desire (hence 'chaste').

What does the research say about Chaste Berry?

Today, chaste berry is one of the most researched botanicals in relation to the monthly cycle. Research has focused on how it interacts with the body's hormonal signalling. Studies suggest it influences prolactin, a hormone that shifts across the cycle, alongside the balance of oestrogen and progesterone.

Clinical trials have looked at its effects on mood and emotional wellbeing and on physical wellbeing in the days before a period.
