Many of us probably associate sloe berries with gin making, which is definitely one of the most popular uses for the berries, which some people also call the fruits of the Blackthorn tree.
Personally, I don’t like gin, but I do really like the Blackthorn, a tree richly steeped in mythology and folklore, and whose berries can be used in other ways if you were so inclined to try them.
If you come across a Blackthorn, some call it a tree, some think of it more as a shrub, it is related to Hawthorn, but it’s thorns are much longer, and while the Hawthorn is much associated with love and healing of the heart, the Blackthorn unfortunately has had some darker tales associated with it. This is mainly because of the use of the thorns to harm others, and its links to warfare.
It’s said in Scotland, winter begins when the ground is struck by the Cailleach, Crone of Death, with her Blackthorn staff.
And the tree is associated with the darker side of witchery, where the long thorns would be fixed to the end of a club to harm others, and witches would go walking with their Blackthorn staffs.
Poor Blackthorn, for it really is a beautiful tree, and has also been used for protection, such as being called upon when one needed a thick hedge of impenetrable thorns to stop a pursuer. Or keep someone out, as in the tale of Sleeping Beauty.
And it is said that time spent with the tree will help to purify and cleanse away negative emotions, so that you can be ready to bring in the new.
Medicinally, Blackthorn has been used for its astringency, the flowers and sloes for helping with upset stomachs, sore throats, inflammation of the mouth and also for purifying the blood. The sloe contains minerals such as calcium and magnesium, and also vitamins C, E, phenols, and antioxidants.
It’s best to harvest the berries later in the autumn, after the first frosts have arrived, and the cold temperatures have helped to soften and make them more flavoursome.
Eaten raw, the sloes are quite astringent and can dry the mouth, hence why they are more commonly used for making into syrups, jams, or for adding flavour to alcohol.
When using them, it’s also best to strain out the seeds as they contain small amounts of amygdalin, and can be toxic.
