Medicinal use of Variegated Horsetail:Horsetails have an unusual chemistry compared to most other plants. They are rich in silica, contain several alkaloids (including nicotine) and various minerals. Horsetail is very astringent and makes an excellent clotting agent, staunching wounds, stopping nosebleeds and reducing the coughing up of blood. It helps speed the repair of damaged connective tissue, improving its strength and elasticity. The plant has been used in the treatment of sore eyes.

Habitat of the herb:Dunes, river banks, wet ground on mountains etc, to 480 metres.
Other uses of Variegated Horsetail:The stems contain 10% silica and are used for scouring metal and as a fine sandpaper.

Known hazards of Equisetum variegatum:Large quantities of the plant can be toxic. This is because it contains the enzyme thiaminase, a substance that can rob the body of the vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase. The plant also contains equisetic acid - see the notes on medicinal uses for more information.
