Boldo (Peumus boldus)

Shepherd’s Purse (Capsella bursa-pastoris)

About

Boldo is a strongly aromatic multi-branched evergreen shrub or tree growing to 20 feet. It has egg-shaped leathery leaves with a lemony scent, clusters of white or yellow bell-shaped flowers, and small yellow berries. Native to Chile and Peru, it has become naturalized in the Mediterranean region and the West Coast of North America, where it grows on dry sunny slopes and in mountain pastures in the Andes. It is widely cultivated, and its leaves are gathered throughout the year. Boldo is a valued remedy in Latin American herbal medicine and is used by the Araucanian people in Chile as a tonic.

Shepherd’s purse (Capsella bursa-pastoris) is an annual to biennial plant with a basal rosette of leaves, small white 4-petaled flowers, and distinctive heart-shaped seed pods resembling an old-fashioned pouch. Known for its powerful ability to arrest bleeding, it has been historically used in cases of hemorrhage.

Safety & precautions

Do not take during pregnancy. Subject to legal restrictions in some countries due to the presence of ascaridole, a toxic constituent in the volatile oil. The dose and duration of treatment should be restricted to minimize risk. One case report suggests boldo may interact with warfarin; a woman taking warfarin experienced a modest rise in INR when using boldo (and fenugreek). The mechanism is unknown, and it is unclear whether boldo, fenugreek, or both were responsible. Boldo contains natural coumarins, but their anticoagulant activity is uncertain. Until more is known, monitor INR closely if combining boldo with anticoagulants.

Pregnancy: Avoid; can stimulate uterine contractions. Blood Pressure: Considered hypertensive, so those with high blood pressure should consult a professional. General: Use short-term for acute bleeding concerns.
