Boldo (Peumus boldus)
A native shrub to Chile, Boldo has long been part of the folk medicine tradition of the indigenous people.
Traditionally, Boldo has been used by the Chileans as a liver tonic and as a treatment for Gallstones.
Part of the plant used: LEAF.
Boldo has been used as an infusion at a dose of 3 g per day. It has also been used as an extract and a tincture. However, these forms are generally not recommended due the herb?s high content of ascaridole (1,2). The German Commission E suggests that only ascaridole-free preparations be used internally (3).
Long-term use (more than three to four weeks) of boldo is not recommended. People with kidney disease should avoid boldo, for it may cause kidney irritation (5).
People who are pregnant, nursing, have obstruction of the liver bile duct, or severe liver disease should not take boldo (6).
Boldo may aggravate the hyperglycaemic and hyperuricemic (excessive blood levels of uric acid) effects of glucose elevating drugs. Use with antidiabetic drugs may require dose adjustments.
