Boldo Side Effects

Boldo, scientific name Peumus boldus, is a Chilean plant that has a long history of medicinal use, first by traditional Chilean peoples and now around the world. Although the plant is native to Chile, it was introduced to the Mediterranean region, where it has flourished. As natural medicines have become more widely used, the use of Boldo has increased.

Identification

• Boldo is an evergreen originally from arid areas of South America. A member of the monimiaceae family, it can be identified by its broad, elliptical, leathery leaves and strongly scented white or yellow flowers. It grows as a tree, reaching heights of 25 feet, or a smaller shrub. Boldo plants are either male or female, with female plants bearing an aromatic and edible yellowish-green fruit.

Uses

• Boldo has a long history of use by indigenous peoples as a remedy for liver problems and gallstones. It has also been widely used, both in tincture form and by ingesting dried leaves or bark, as a natural or homeopathic remedy for stomach issues such as indigestion and cramps. It has also been used as an appetite and digestive stimulant, as a diuretic and as a laxative.

  The edible Boldo fruit is also used as a spice for cooking, and leaves are sometimes utilized in the same manner as bay leaves.

  Historically, Boldo bark was used to tan hides, and the wood of the tree was used for charcoal.

Caution

• Boldo has not been approved by the FDA for any uses and has not undergone definitive testing. You should consult a doctor before taking Boldo. Pregnant or nursing women should not take Boldo. People with liver or kidney problems should avoid taking Boldo. Boldo should never be used for prolonged periods of time.

Potential Side Effects

• Ascaridole, a volatile oil, is one of the main constituents of Boldo, which may irritate kidneys (Boldo is available in ascaridole-free forms). In excessive amounts, volatile oils can be toxic. Boldo is also a central nervous system stimulant. Boldo may also cause seizures, heightened reflexes or loss of coordination. Some forms of Boldo may also aggravate liver or kidney problems.

Interactions

• Boldo may increase the effects of central nervous system drugs, warfarin or other anticoagulant drugs and should not be used in conjunction with any of these drugs. If you are currently taking any other drugs, talk to a doctor or pharmacist before taking Boldo.
