Horsetail belongs to the field horsetail family. It is a non-flowering herb that grows up to 50 cm high.
The main ingredients of horsetails are flavonoids, high silicic acid content and plant acids. With its high silicic acid content it strengthens connective tissue, purifies and tautens skin. Flavonoids surround cell membranes protectively and react with free radicals, protecting the skin. The plant acids have anti-inflammatory and astringent effects.
