Horsetail, Equisetum arvense, also known as scouring rush and shavegrass, gained a reputation as a natural wound healer over the centuries. Horsetail, a descendant of prehistoric plants which grew as high as trees, is a rich source of silica, calcium, and other minerals. The silica in horsetail helps to bind protein molecules together and improves the texture and tone of skin and lifeless hair.
An oil infusion of horsetail has been used as a remedy for eczema and other irritated skin conditions. As a clarifying astringent, it closes pores and stimulates the production of new skin cells.
In hair care, horsetail is nourishing and hydrating. It stimulates blood vessels in the scalp and has been used for centuries as a hair-growth herb. The silica in horsetail helps to keep hair strong and adds shine and luster to hair.
