The Latin name of this herb is Vitex agnus castus. Commonly it is known as agnus castus or as chaste berry.

It is not a cactus (it is sometimes mispronounced “agnus cactus”), but a member of the Verbena family.

The name ‘agnus castus’ derives from the Greek for ‘chaste’. According to Pliny, writing in the first century, Greek women wishing to preserve their chastity placed leaves of this plant on their beds and slept on them. Pliny’s contemporary, Dioscorides, claimed that Agnus Castus preserved chastity because it smells so bad that, when strewn on the bed, it was enough to deter amorous advances from men!

Agnus Castus was certainly used widely by the ancient herbalists. Dioscorides even concurs with its current uses; “it both brings down the milk and expels the menstrua”.

Although not a native plant of the UK, records indicate that it was in use here by 1500. It is then mentioned in Gerard’s herbal in the seventeenth century. Until recent years, though, you would have difficulty finding much written in UK herb books about agnus castus. It is in the rest of Europe that the herb has had the most use over the past century.

Only in the last ten years has it become popular again in the UK – and, now, in America.

Uses of agnus castus

The herb is mainly known as a remedy used by women. I will concentrate on its effects for PMT and menopause – its main uses today.

The effect it has on female hormones is largely a balancing effect. This ‘normalising’ influence makes it useful in a wide range of situations. And it can be helpful for a large proportion of the time – some studies indicate improvements in symptoms for 90% of sufferers from PMT.

PMT – agnus castus can improve headache, breast tenderness, fatigue, bloating, anxiety and similar symptoms, irregular cycle and short or long cycle.

Menopause – symptoms agnus castus can improve include: night sweats, hot flushes and fatigue.

Although agnus castus is recommended by several sources for increasing breast milk – as referred to by Dioscorides – I have come across little evidence for this.

Combinations with agnus castus

You may also see agnus castus combined with other herbs in agnus castus combination products such as for the menopause. (It could also be for help with monthly periods.) It often happens that a combination of herbs will be more effective than a single herb. There are a number of agnus castus combination products. Find a product which works for you – either the single herb or a combination of herbs – and then continue with it for a full course of treatment.


Do not take agnus castus during pregnancy; and it would be wise to avoid it when taking any other product or drug which affects the female hormone system – such as HRT or the contraceptive pill.

Reports of negative reactions to agnus castus are few. About one in 50 people may experience mild indigestion, or a mild skin rash. If this happens, stop taking the herb, temporarily, then re-introduce it more slowly.

Keeping a record of your health

As always where your health is concerned – keep a record. Note in a diary how you are feeling when taking agnus castus or an agnus castus combination. This is often very useful when deciding how beneficial a treatment has been. It can also be helpful information for a practitioner, should you consult one.

This is an interesting article about the agnus cactus, do you know where they are sold in any herb or vitamin stores that u know of ?

You should be able to buy Agnus castus in most good health food stores and online just check the ingredients to make sure it is a good quality product and not mixed with additives. The link below will take you to a quality supplier based in the UK but they do ship internationally

Just to say that I took Agnus Castas for very many years, and it was so helpful.

I suffered really badly with breast tenderness for 3 weeks. Within 2 hours of taking 2 tablets of this product I felt better , less pain, less irritability and I was able to touch my own skin.
A fabulous product – stronger and more effective for serious pain than evening primrose oil.
If you are in pain of any sort get this product quickly and stop suffering unnecessarily.

Hi Julie

Agnus castus may help your symtpoms and is definitely worth a try. I can also suggest Femarone 40+ – a formula designed for those with menopause symptoms and hormonal imbalances. Please see link below for more information. Also you can contact Specialist Herbal Supplies for more advice if needed.
Kind regards

Hi Annie
You could certainly try Agnus Castus but it would be a good idea to see a nutritionist / herbalist who could guide you through a more thorough treatment including diet and herbs.

Well into menopause no periods but hot flushes still. Had a pituitary tumour removed 22 yrs ago. No mediation, is it alright to take agnus cactus


robralph October 28, 2016 at 12:46 pm

Hi Tracey

I see no reason why it shouldn’t be. It’s worth a try and if it doesn’t help, let me know. There are other herbs also worth trying.

I just received organic agnus castus powder. I was perimenopause and the past 3 months haven’t had a reg. period (only some spotting). The vitamin place told me to mix 1/2 tsp. into a glass of water once a day. Is that good? should I take it w/ anything else like vit. C or mag? Thank you.


robralph July 3, 2017 at 10:39 am

That sounds fine – no need to take with anything else to improve absorption etc unless you wish to take those vitamins too.
