Common Nasturtium

This colorful and delicate annual is from Peru, where it was once used to treat skin wounds. Nasturtium is well known for its edible spicy flowers and leaves; what may not be so well known is that it has a high content of vitamin C and effectively treats infections and may help relieve colds. It was first brought to Europe in the seventeenth century and first cultivated only in abbey gardens for medicinal usage. Today, nasturtium is used in cooking and as an herbal remedy. The plant's peppery leaves make a delicious addition to a salad - as long as pesticides weren't used on the plant! Nasturtium is most often used to stimulate the appetite and promote good digestion - a perfect blend of the delightful plant's culinary and medicinal properties.Nasturtium is an easy, colorful plant to grow and is available with trailing, climbing or mounding habits and either dark green or variegated leaves. Plant it in full sun or partial shade for a large harvest of leaves and flowers all summer long.
Plant Facts
Nasturtium is an annual belonging to the Tropaeolaceae family. Both the trailing and bushy varieties have yellow, orange, pink and red flowers with long spurs that bloom during the summer. The stem is located in the center of the funnel-shaped leaves.

OriginNasturtium is originally from South America; it was first cultivated in Peru. Today the colorful plant is grown in both tropical and temperate climates throughout the world. Parts UsedThe leaves and flowers are used medicinally. The leaves, flowers and seeds, all edible, also have a number of culinary uses.

ComponentsNasturtium contains glucosinolates, a mustard-oil glycoside; glycotropeoline, which releases a disinfectant sulfur compound when added to water, which have antibiotic and anti-tumor effects. They can also alleviate respiratory congestion, stimulate the digestive system and mitigate hyperthyroidism; and many flavonoids. The plant is also a great source of vitamin C, which the flavonoids help the body to absorb. Some small amounts of usable iodine are also present, helping to regulate metabolism. Nasturtium has spilanthol, oxalic acid and the enzyme myrosin, too.

Indications
A delicious medicinal remedy, nasturtium is an effective treatment for the symptoms of topical and internal bacterial infections, most especially those affecting the skin and urinary tract, as well as the respiratory and digestive systems. It can also be used to treat fungal infections, such as Candida. Colds and flu's may be remedied by this herb as well, although whether nasturtium has antiviral properties or not is still unknown. Caution: Ingesting excessive amounts of this plant can result in vomiting, and leaving it on the skin for longer than 10 minutes may induce a painful burning sensation. Nasturtium's disinfectant properties are the result of its mustard-oil content. Since the oil is released in the gastrointestinal tract, eating nasturtium in large quantities or too frequently can irritate these delicate mucus membranes. However, for normal food consumption, nasturtium is generally considered safe.
Therapeutic Effect
The herb's mustard oils are antibiotic, antifungal, antiviral and antibacterial; these properties can help to treat infections, colds, flu and digestive upsets that stem from an overgrowth of yeast or from parasites. Nasturtium also boosts the immune system, which helps the body to resist infections. Further, it stimulates the appetite, promotes digestion and supports metabolism. Mildly warming, nasturtium makes an ideal chest plaster for coughs.

The pungent flavor of the leaves adds a piquant note to green salads. You can also shred the leaves and use them in egg dishes or mix them with soft cheeses.

The decorative nasturtium leaves have a slightly peppery taste, similar to watercress. The plants, however, are not related.

Use the delicate flowers to flavor sorbets, custards, jams, jellies, teas, liqueurs, fruit punches and wines.

Chop the flowers and add them to risotto. Or toss them with olive oil as a topping for pasta dishes.

The attractive flowers add bold dashes of color as a decoration or garnish for cakes and pastries.

The leaves are most tender in the spring, before the plant has flowered. Pick the blossoms in the early morning and in dry weather. Rinse in cold water.
