Horsetail, derived from the plant Equisetum arvense, is one of the oldest living plant species and has a long history of use in traditional herbal medicine. Its notably high silicon content has drawn scientific interest, and research suggests it may support bone health by contributing to collagen formation and mineral density. Studies indicate that horsetail extract may also promote stronger hair and nails, with preliminary research showing improvements in hair growth and reduced brittleness over time. Additionally, horsetail has traditionally been used as a mild diuretic to support urinary tract health, and some evidence points to potential benefits for wound healing due to its antioxidant and anti-inflammatory properties. While findings are promising, much of the research remains in early stages, and further clinical trials are needed to confirm these effects.
