Equisetum arvense. Horsetail is a mineral-rich, deeply restorative herb traditionally used in Western herbal medicine to strengthen connective tissue, support healthy bones, and promote the integrity of the skin, hair and nails. Naturally high in bioavailable silica, it plays an important role in collagen formation and tissue repair, making it particularly valuable during recovery from injury, fracture, surgery or chronic connective tissue weakness. Horsetail also acts as a gentle diuretic, supporting healthy urinary tract function and assisting the elimination of excess fluid. It has traditionally been used for recurrent urinary tract infections, mild oedema, and irritation of the urinary system, while its astringent properties help tone tissues and reduce minor bleeding.
