Horsetail (Equisetum arvense)
Equisetum is often called a "living fossil" because it had dominated Paleozoic forests in forms of large trees. The name horsetail is used for the entire group of species; Equisetum derives from the Latin equus (meaning horse) and seta (bristle). Stems are coated with abrasive silicates, making them useful for cleaning metal items, particularly those made of tin.
Stems are collected in summer, their tea is used as a diuretic and a cure for bacterial diseases or infections of the urinary tract due to its antiseptic qualities. Horsetail is a key ingredient in detoxifying and weight loss treatments and it is also used for rheumatic pain.
Horsetail infusion can be used for boils and eczema or as an anti-perspirant soak for feet. The plant contains silica derivatives, flavonoids and other beneficial ingredients that improve skin's elasticity and prevent premature ageing. Flavonoids have an antioxidant effect, improve the permeability of capillaries, stimulate circulation and help supply the skin with vitamins, nutrients and oxygen.
