So named because its branches were a traditional source of broom straw used by butchers, this Mediterranean evergreen bush has a long history of traditional use in the treatment of urinary conditions. More recently, it has been studied as a treatment for vein-related conditions.

Butcher's broom has been approved by Germany's Commission E as supportive therapy for chronic venous insufficiency. Venous insufficiency, a condition closely related to varicose veins, involves pain, swelling and fatigue in the calves. Commission E also recommends butcher’s broom for the treatment ofhemorrhoids.

This recommendation was in place before any meaningful studies had been performed evaluating butcher’s broom for either of these purposes. However, several studies performed subsequently now provide preliminary supporting evidence for its use in chronic venous insufficiency.

No substantial studies have evaluated butcher’s broom for hemorrhoids, but because hemorrhoids are similar to varicose veins, it is a reasonable supposition that butcher’s broom might be helpful.

Various treatments used for venous insufficiency have also shown promise for treating arm swelling (lymphedema) following surgery for breast cancer. One study suggests that butcher's broom may be helpful for this condition as well.
