Horsetail (Equisetum arvense), also known as horsetail because of its characteristic appearance, belongs to the horsetail family (Equisetaceae). The plant is common in Europe and grows in a variety of locations, such as meadows, along roads, on fallow land, and on slopes.
Horsetail is one of the oldest plant species on earth, having existed for approximately 390 million years. The plant is distinguished by its deep root system, which allows it to absorb nutrients from deeper soil layers. As a result, horsetail naturally contains various plant compounds, including minerals, fiber, and silicon.
