Nasturtium -Seeds Image

This well known and often used annual knows no boundaries in the garden.

With it's distinctive spurred flowers and large generous leaves Nasturtium is the stuff of childhood memories and no family garden should be without it.
Although Nasturtium will grow at almost any time of year in most climates, it is at it's best in late winter and spring.

The leaves and flowers of Nasturtium are very edible and add their distinctive flavour to any meal.
We find the seeds of the Nasturtium are an excellent tonic for the cold and flu season and if treated in the same fashion as 'capers' are an interesting food.

Side Effects

Nasturtium contains benzyl mustard oil (benzyl isothiocyanate). Benzyl mustard oil can cause skin and mucosal irritations. Used internally, gastrointestinal disorders may occur. One case of the occurrence of a transient, urticarial exanthem was reported after ingestion of mustard oil from nasturtium. Benzyl mustard oil acts as a contact allergen if applied to the skin.
Special Cautions for Use

None known.
Use During Pregnancy and Lactation

None known.
Interactions with Other Drugs

None known.
Dosage and Mode of Administration

In older studies, mono-preparations of extracts were applied in daily dosages equivalent to 3 times 14.4 mg benzyl mustard oil. The dosage for combinations depends on the contribution of the herb in the specific combination, which in each case must be documented.

Overdosing can cause albuminuria, which apparently is due to damage to the glomerulus and tubulus system.
Special Cautions

None known.

Based on the pharmacological properties, a qualitatively positive contribution to the effectiveness of combinations for supportive treatment of infections of the lower urinary tract, catarrhs of the respiratory system, as well as topical application for mild muscular pain can be assumed.
Effects on Operators of Vehicles and Machinery

None known.
