Nature’s Sunshine Horsetail and Rosemary

(vegetal silica)

Horsetail is widely distributed throughout the temperate climate zones of the Northern Hemisphere. Horsetail is a unique plant with two distinctive types of stems. One variety of stem grows early in spring and looks like asparagus, except for its brown colour and spore-containing cones on top. The mature form of the herb, appearing in summer, has branched, thin, green, sterile stems and looks like a feathery tail.

Reportedly first recommended by the Roman physician Galen, a few cultures have employed horsetail as a folk remedy for kidney and bladder troubles, arthritis, bleeding ulcers, and tuberculosis. In addition, the topical use of horsetail was used traditionally to stop the bleeding of wounds and promote rapid healing. The use of this herb as an abrasive cleanser to scour pots or shave wood illustrates the origin of horsetail’s common names—scouring rush and shave grass.
