    Nikki's commentary

    This is an invaluable medicinal plant from our native flora as well as being very beautiful. I find just sitting with the plant to be so calming and soothing, especially when its lovely white flowers are open.
    It is a close relative of the elderflower, and you can see this in the similarity in the flowers.
    Although the stem bark is the part traditionally recommended, myself and quite a few of my colleagues use a ‘cheat’ when preparing medicine from it. We prune the shrub and use the whole small twigs rather than peeling off the bark.
    We have used the twigs to make a deep decoction, reducing the volume of the liquid to a 1/10th and the used this in cream for treating menstrual cramps and other cramps. It is amazingly effective. I also give dropper bottles of the fluid extract to women who have menstrual cramping to take- 10 drops when the period starts and then repeat every hour until the cramping stops-often one dose is sufficient. It can also help reduce heavy menstrual bleeding and is quite sedating and calming too. For heavy bleeding in the perimenopausal years, it can be very helpful, reducing both the heaviness and the anxiety that often occurs in perimenopause as oestrogen is dropping. During labour it can help to relax the uterus into effective contractions if the womb is too tense this prevents effective contractions.
     I also use this amazing medicine in pain mixes as often a lot of pain is accompanied by spasms in the muscles.  It is especially valuable if there is laxity or degeneration in the joints.
    It can be very valuable for reducing high blood pressure if there is a lot of tension in the cardiovascular vessels or nervous tension. When people are experiencing cold hands and feet due to vasoconstriction (for example Raynaud’s or ‘white finger’) it improves the circulation by relaxing the blood vessels. I often combine it with bilberry, yarrow or ginger for this.
    It can also help relax the bowel in irritable bowel syndrome and for this, I might also put in some wood betony, peppermint, fennel or chamomile.
    For the respiratory system in asthma when there is bronchospasm present I combine it with Grindelia or wood betony.
    Some people also tincture the berries or prepare them as an acetum. They have a brilliant red colour which they also give to the medicine and this is often used for menstrual problems.
    And here is our monograph if you want any of the technical or growing stuff.
