Agnus castus: The balancing herb for PMS

How much do you know about Agnus castus?

Your menstrual cycle

There are two main hormones which control the cycle, oestrogen and progesterone. During the first half of your cycle, your oestrogen levels rise, you ovulate and its levels start to fall. Progesterone levels start to rise during the second part of your cycle and this is when your PMS symptoms can start to make their effects felt if your levels aren’t sufficiently high – hello to mood swings, headaches, sore breasts etc.

So, how will Agnus castus help with this?

Well, it will balance the hormone levels as it helps to increase progesterone, thus thwarting the oestrogen dominance that’s contributing to the monthly PMS miseries experienced by so many of us ladies.

Fantastic, I hear you say, so a few drops of Agnus castus each month and PMS will be banished – it’s good, but it’s not that good. It needs to be taken every day of the month, and it can take up to 3 months to reach its full effect. However, if you think about it, that’s only 3 cycles and fortunately, the majority of women notice improvements within 1-2!

Agnus castus can be taken long term, however, once improvements are felt then there may no longer be the need to continue – you can always start to take it again should the improvements no longer be felt.

Remember that Agnus castus cannot be used alongside any other hormone-balancing products, such as the Pill or the Mirena coil, for example.

The reason for the contraindications is that contraceptives work by deliberately creating in imbalance in your hormones. Clever old Agnus castus will most likely rebalance them and in doing so, will prevent the medication from working.

    Hi I notice that you can get Agnus Cast us in tablet form, are there advantages to a tincture or is it just down to preference ? Thanks Lisa

      Hi Lisa, yes, generally tinctures with an alcohol base are thought to be better absorbed than tablets that we need to break down and then successfully absorb.

    Hi there,Im 42&suffer from low mood around ovulation&migraines/anxiety/v low mood few days before my period.This goes around day 3 of period. My cycle changed from 28days to 21 for a while but this month was day 27 so it's hard to measure when migraines will come! Basically I'm finding it hard to cope with almost 2 weeks out of every 4 feeling so rough. My doc is really understanding&doing tests for oestrogen dominance but I don't want to take synthetic hormones. Do you think Agnus cactus could help? Many thanks,Liz.
