Canada wren (Erigeron canadensis)

Other names: Conyza canadensis, Horseweed, Canadian horseweed, Canadian Fleabane

The Canadian turnip (Erigeron canadensis), also known as Conyza canadensis, Horseweed, Canadian horseweed and Canadian Fleabane, is an annual plant native to North America. In its native country it is often considered a weed because it rapidly colonizes disturbed habitats such as fields, pastures or roadsides. In the Czech Republic, Canada thistle is assessed as an invasive species, and its distribution can disturb native biodiversity. It has a straight, branched stem with sparse hairs and rather small, sparsely hairy leaves. The flowers are small, collected in compound clusters, typical of the star family.

But the Canadian turnip also has its uses. It has medicinal properties and is used mainly in folk medicine. It contains flavonoids, gums, gums, resins and essential oils which, when used properly, have antiseptic, anti-inflammatory and diuretic properties. Its exudation can help in the treatment of diarrhea, urinary tract inflammation or hemorrhoids. In addition, it is also used as an insecticide - it kills or drives away insects. In some countries, this plant is also used as cattle food, as it has a high protein content. Turmeric is also added to aromatherapy products and oils due to its strong fragrant aroma. Its seeds are used in cosmetics as exfoliating particles. However, due to its invasive nature, its collection and use is regulated by law.
