Spiny restharrow, a bushy, prickly shrub of embankments and dry meadows across Europe, was long regarded by old-time herbalists as the plant of the kidneys and urinary tract. It was sometimes also called the ‘ox-stopper,’ so tough were its roots that they could resist the plough and the ploughshare.
Restharrow root was traditionally used as a herbal tea to promote urinary elimination and support comfort in the urinary tract.
It was included in seasonal depurative blends, alongside other roots, to support the body's elimination functions.
Root decoctions were also reputed, in certain regions, to help with mild joint and rheumatic discomfort.
Combined with other plants, restharrow featured in traditional preparations meant to support harmonious digestion and elimination.
Not advised in cases of edema linked to heart or kidney failure, except on medical advice, given its effect on water elimination. Not recommended during pregnancy or breastfeeding, for lack of sufficient data. Avoid prolonged use without the advice of a healthcare professional. Seek advice from a pharmacist or herbalist if taking concurrent medication, particularly diuretics.
