For many hobby gardeners it is a curse, for our health a true blessing: the field horsetail, Equisetum arvense, also known as horsetail. As a descendant of plants that grew as tall as trees in prehistoric times, today’s dwarf plant is still full of strength.

Women in particular should make use of this herb. The plant has a lot of healthy components to offer and as a medicinal herb it can combat various ailments and can be used for prevention. It’s much used in Traditional Chinese Medicine, Ayurveda and other alternative medicines.

Applications and effects

In the past, horsetail was often used for cleaning tin, as the silicic acid is embedded in the plant in the form of crystals. This is how it got the widespread name horsetail. The “water doctor” Sebastian Kneipp rediscovered it as a medicinal plant and used it for better wound healing and against rheumatism and gout.

Silica or silicic acid (Silicium), a whitish grained mineral, is found everywhere in and on earth. It is a firming component from rock to the cell walls of plants.

Humans need silica to build:

        • Connective tissue
        • Tendons
        • Skin and hair
        • As well as the hard substances such as bones, teeth and nails

The high silica content makes horsetail very valuable for middle-aged and older women. Women with weak connective tissue and/or vein problems find in horsetail tea a natural helper. It also strengthens their bones and promotes the elasticity of their skin.

Horsetail extract is a true all-rounder in health matters. Its concentrate and extract are available ready to use.

In cases of urinary tract disorders, it has a urinary tract strengthening and calming effect, alleviates irritation and urinary tract infections and promotes urinary excretion.

Horsetail tea is recommended as a gargle or mouthwash in cases of tonsillitis, gingivitis and atrophy (periodontosis). For rheumatism, gout and weakened joints, in addition to baths with horsetail, a cup of tea should be drunk daily throughout the day.
