Today, horsetail continues to have medicinal value. The plant's stems are rich in silica and silicic acids, which help mend broken bones and form collagen, an important protein found in connective tissue, skin, bone, cartilage, and ligaments. Horsetail is also used to treat infections of the urinary tract, kidney and bladder stones, and as topical therapy for burns and wounds.
Why bioflavonoids, and why from spring horsetail? Because chelated silica is the only kind of silica the body can absorb and the spring horsetail has a higher percentage of this silica than any other plant.
