Some of you may know it can be used in salads – the flowers and seeds have a slightly peppery taste. It also has some terrific effects when used as an Herbal Medicine. As an herbal medicine Nasturtium, which has the botanical name Tropaeolum majus, is used as a tea, or as a liquid extract when a greater or more specific effect is needed. The liquid extract is a much stronger concentrated form; the alcohol in the extract helps to draw out more of the medicinal actions of the herb. For this reason care has to be taken to follow the recommended doses of Liquid Herbal Extracts.
Nasturtium helps the body get rid of excess fluid; i.e. it has a diuretic action . Fluid retention can be associated with a number of health problems; so it is best to investigate and understand the reasons it may be happening to you.

Additionally, some diuretics can put a strain on the kidneys, however, research on Nasturtium shows it is does not adversely affect the kidneys and is safe to use .
Nasturtium helps support immunity on many levels; it helps to fight infections and assists recovery. In a large study in Germany it was found to be as effective as antibiotics in treating acute sinusitis, acute bronchitis and acute urinary tract infection and was deemed safer too !
Research has found Nasturtium contains certain compounds in it that help reduce blood pressure .
