Equisetum tincture is made from the Equisetum arvense plant, also known as horsetail, which is one of the oldest forms of plant life on Earth. Rich in silicic acid, horsetail has traditionally been used to strengthen connective tissue, bones, nails and hair. Equisetum also contributes to the body’s natural detoxification through its mild diuretic action, while containing antioxidant and anti-inflammatory compounds that enhance overall well-being.
