You have probably walked past this wayside plant and not taken much notice of it but this little inconspicuous plant has a long history of use as a medicine, dating back to the ancient Times.
Barbarakraut or as we know it; Winter cress ( Barbara vulgaris) often grows in damp areas.
St Barbara is the patron saint of miners, gunners and quarrymen: all vulnerable to danger from explosives. Winter cress was dedicated to her as its leaves were used in healing wounds from such explosions.
St Barab's day is celebrated on December 4th and Winter cress can be seen growing then at a time of year when not much greenery is.
Please note that this true winter cress has yellow flowers, not white flowers of the winter cress of commerce.
The freshly gathered leaves and flowers can be added to salads or made into a tea for medicinal purposes.
It's bitter action aids digestion, it's anti inflammatory action can be useful for arthritis and rheumatism, it's diuretic properties can aid excretion of toxins and it's VitC content can support the immune system.
The leaves can be made into a compress for skin conditions.
The active ingredients are: mustard oil glycosides, which have an antibacterial and anti-inflammatory effect, flavonoids which have an antioxidant effect, protecting the body from free radicals and Vit C, which strengthens the immune system and supports the formation of collagen, important for the skin and joints.
Cruciferous vegetables like Broccoli and cabbage are also in the Brassicaceae family and contain mustard glycosides too.
