Nasturtium - Medical use:

The Benzyl contained in the Nasturtium has antibacterial and circulation-promoting. Also suitable for consumption are the young leaves as a seasoning ingredient for salads. The flowers can be used as an edible ornament. Closed buds and immature seeds, pickled in vinegar and brine, served as caper substitutes in times of lack. Infections of the respiratory tract and urinary tract were used. With its high content of vitamin C, it serves both the prevention and the therapy. Even more important are the glucosinolates contained in the plant: they cause the typical pungency and are converted into mustard oils in the body. These inhibit the multiplication of bacteria, viruses and fungi. In addition, they promote blood circulation.

Experts compare the effectiveness of the herb even with that of antibiotics. Combined with horseradish root, the plant's herb combats sinusitis, bronchitis and bladder infections.
