Equisetum arvense

Equisetum arvense, commonly known as the field horsetail or common horsetail, is a herbaceous perennial plant in the Equisetaceae family. It is native to the Arctic and temperate regions of the Northern Hemisphere, and it is known for its distinctive segmented stems and spore reproduction.

Description

Equisetum arvense is a rhizomatous plant with a vertical stem that can grow up to 60 cm tall. The stem is hollow and jointed, with a rough, ridged surface. The plant has two types of stems: sterile and fertile. The sterile stems, which appear in summer, are green and photosynthetic, while the fertile stems, which appear in spring, are brown and non-photosynthetic.

Distribution and habitat

Equisetum arvense is widely distributed across the Northern Hemisphere, including North America, Europe, and Asia. It is found in a variety of habitats, including wetlands, grasslands, and woodlands. The plant prefers moist, sandy soils and is often found near streams and rivers.

Uses

Historically, Equisetum arvense has been used for various medicinal and practical purposes. It has been used in traditional medicine to treat conditions such as kidney stones, urinary tract infections, and wounds. The high silica content of the plant has also made it useful for polishing metal and wood.

Cultivation

Equisetum arvense is a hardy plant that can tolerate a range of conditions. However, it can become invasive if not properly managed. It is propagated by spores, which are produced in cone-like structures at the tips of the fertile stems.

Conservation

While Equisetum arvense is not currently considered threatened, its habitat is being lost due to urban development and agricultural expansion. Conservation efforts are focused on preserving its habitat and preventing its overharvesting for medicinal use.
