Chilcuara: what it is, characteristics, properties, uses

What is chilcuara?

The chilcuara or chilca (Baccharis latifolia) is a wild shrubby plant, abundant in South America, traditionally used as a medicinal plant. Depending on the locality, it is known by various names: azumiate, yellow cistus, chilcuara, chilca, chilkha, bitter chilca, jaguar grass or cucamarisha.

It is a natural species of temperate and dry regions that grows near water sources, such as rivers and lakes. It is common to find it in areas ranging from the southern United States and Mexico to the temperate areas of Chile and Argentina.

In traditional culture, different healing and medicinal properties are attributed to the chilcuara or chilca. Since ancient times it was used topically or as an infusion to alleviate and cure different ailments and diseases.

A decoction of clean and fresh chilcuara leaves is effective for the treatment of gastrointestinal and liver ailments. Likewise, as an infusion it has antiparasitic and antidiabetic properties, cures insomnia and rheumatism, and has expectorant functions.

External applications of the macerated leaves, stems and flowers are also used to relieve inflammation and abrasions of the skin.

On the other hand, wild crops are favorable for bee production thanks to the abundant flowering that attracts these pollinators. The bees gather around the chilca plants, preferring their nectar to that of other floral species.

Characteristics of the chilcuara

The chilcuara is a very branched and dense shrub species that can reach 1 to 2 meters in height.
It has a deep taproot with numerous secondary roots, which allows it to keep the plant hydrated in times of drought.
Being a bushy plant, it develops various stems that branch from the base. These are thick, with a woody consistency and a rough appearance. The filiform glabrous leaves are toothed and lanceolate, 10-15 cm long and 2-4 cm wide, and glossy green.
The vegetative period is continuous throughout the year and flowering begins during the wet months, from November to March. The tiny male and female flowers are grouped in a panicle-shaped inflorescence, with reddish tones and white spots.
The ovoid and hairy fruits, similar to small nuts, are grouped together forming numerous clusters, and are differentiated by the filaments that cover the fruit. The seeds are very small and light.
Reproduction can be carried out sexually through seeds, or asexually, through rooted basal branches. The traditional way of reproducing this species is through juvenile individuals obtained from the mother plant.
However, in various areas it is classified as an invasive plant. Indeed, under favorable conditions it adapts quickly, coming to replace native species and altering local ecosystems.
This species contains essential oils and phenolic compounds that alleviate various ailments when used topically or taken in infusions. The leaves can be applied to wounds or skin conditions, and leaf infusions relieve digestive problems.
The flavonoid content of chilcuara allows it to be used in the industrial field as a natural colorant. The leaves of the plant, macerated and boiled in water, are used as dyes for yellow and green tones.
