Medicinally used green summer shoots of horsetail. The extracts of the horsetail herb contain about 10% mineral components such as silicic acid and water-soluble silicates; furthermore 0.2-0.9% flavone glycosides (mainly kaempferol and quercitin), polyenoic acid, bitter substances and resins. Alkaloids such as nicotine also occur in small amounts.

Since silicic acid does not volatilize, you can prepare larger quantities of horsetail tea at once.

Caution: confusion with other horsetails such as swamp horsetail, which contains much more toxic alkaloids.

During irrigation therapy, ensure sufficient additional fluid intake - at least 2 l / day extra!
