Horsetail (Equisetum arvense) is an ancient plant known for its high silica content, which is great for promoting healthy hair, skin, and nails. When it's cut and sifted, it's typically in a form that's ready to be brewed into tea or used in herbal infusions. It’s often used for its diuretic properties, as well as for supporting bone health due to the silica and other minerals in it.

People also use horsetail for its potential to help with wound healing or even as a natural remedy for urinary tract health.
