In this article, we take a look at what boldo is, its uses, and medicinal properties and the benefits of consuming this plant, as well as its main contraindications.

What is boldo?

Boldo, also known by the scientific name Peumus boldus, is native to southern Chile located on the South American continent. This is the only species that belongs to the Peumus genus and it is a part of the monimiaceae family.

The boldo plant is a tree with highly aromatic leaves used for both their medicinal and culinary properties, especially in South and Central America. This tree forms a part of the vegetation found in southern and central Chile, specifically in the southern part of the Coquimbo region.

This tree grows in moist environments with constant light, reaching up to 15 m in height, although it develops very slowly. On the same note, the boldo plant blooms in August and September, presenting beautiful little white blossoms in groups of 12. This Chilean plant bears drupe fruits, in other words, fleshy fruits with pits. These are sweet and yellow-green in color.

Lastly, regarding its origins, the leaves of this tree have been consumed for medicinal properties for over 14,000 years. After this, it was slowly introduced to Europe and Africa.

The benefits of this plant often come from its fruit which you can eat either raw or cooked. Likewise, the leaves of this tree are commonly used to make  boldo  tea to treat certain afflictions, and particularly those related to the liver. It usually grows in temperate regions, mostly in Chile, but it is also found in Argentina and Peru.

Boldo tea benefits

Regarding its properties, this medicinal plant is rich in essential oils like cineol, eucalyptol, and ascaridole. Boldo also contains high levels of flavonoids and tannins.

These elements have therapeutic benefits including its effects as a sedative and calming agent and as an expectorant. Besides, it works against inflammation and is a carminative which helps to reduce swelling and gasses in the digestive tract.

Cineol is an essential oil which gives this plant a lemony scent. As we mentioned before, flavonoids are substances that reduce the risk of experiencing heart problems and tannins also work as antioxidants in the body. Besides, other organic compounds called alkaloids make boldo a natural diuretic.

All of this helps to eliminate liquids from the body naturally and therefore takes care of the liver, as well as aiding in bile production and expulsion.
