What is Angus Castus?

The herb Agnus Castus, also known as Chaste Tree, Monk’s Pepper, Chasteberry and Vitex is a shrub native to the Mediterranean and Asia. Agnus Castus is a herbal fruit typically used as a herbal remedy in herbal medicine known for it’s ability to support women's reproductive health, with a focus on relieving PMS symptoms.

As well as supporting women's health, Agnus Castus is also used in Turkish medicine for it’s digestive supporting properties, working as an antifungal tonic.

There is no difference between Chaste tree and Agnus Castus - they are simply different names for the same plant. The plant gets its name following the belief that it is an anaphrodisiac (decreasing libido) for men.



What are the main uses of Agnus Castus?

Traditionally, Agnus Castus is used for its ability to improve conditions that affect women's reproductive system such as PMS - it is known to help with common PMS symptoms including irritability, breast pain or tenderness and cramps. Research has shown the mechanism of Agnus Castus has an impact on the hormone prolactin, decreasing the levels that are circulating in the body. The decrease in prolactin shows correlation between the rebalancing of further sex hormones such as oestrogen and progesterone – therefore having significant impact in reducing PMS symptoms.

3) Easing of breast pain/tenderness – sore breasts before your period are likely do to with the high and elevated levels of a hormone called Prolactin. Research has shown the mechanism of Agnus Castus has an reductive effect on the hormone prolactin, therefore easing breast tenderness.

The hormone stabilising properties of Agnus Castus aid in the normalisation of progesterone levels to help establish healthy and regular periods. It is important to note that it can take a few months to work and should be used alongside a healthy and balanced diet.
