Etymology
The word 'Equisetum' derives from the Latin word 'equus', meaning horse, and 'seta', meaning bristle or seta. This refers to the appearance of the plant's stems, which resemble the tail of a horse. Equisetum has a long fossil record, with its ancestors appearing during the Carboniferous period. Being one of the oldest plant genera, Equisetum is often studied in paleobotany to understand plant evolution. The plants that belong to this genus are notable for their ability to thrive in various conditions, including disturbed habitats. Over the centuries, various cultures have utilized Equisetum not just for its aesthetic qualities but also for medicinal properties, due to its high silica content.
