Description
"Horsetail" (Equisetum arvense) is a perennial plant naturally rich in silica, a mineral essential for connective tissue integrity. It promotes hair, skin, and nail strength while supporting collagen formation for joint flexibility and bone health. In addition, this plant possesses mild diuretic properties, aiding fluid balance and kidney function. Its astringent qualities support skin recovery. Long used in traditional herbal medicine, horsetail remains a respected botanical for structural and metabolic wellness.
