The true Nasturtium (Tropoeolum majus), or greater Indian Cress grows and is cultivated in our flower gardens as a brilliant ornamental creeper. It was brought from Peru to France in 1684, and was called La grande Capucine, whilst the botanical title tropoeolum, [133] a trophy, was conferred because of its shield-like leaves, and its flowers resembling a golden helmet. An old English name for the same plant was Yellow Lark's heels.
Two years later it was introduced into England. This partakes of the sensible and useful qualities of the other cresses. The fresh plant and the dark yellow flowers have an odour like that of the Water-cress, and its bruised leaves emit a pungent smell. An infusion made with water will bring out the antiscorbutic virtues of the plant which are specially aromatic, and cordial. The flowers make a pretty and palatable addition to salads, and the nuts or capsules (which resemble the "cheeses" of Mallow) are esteemed as a pickle, or as a substitute for Capers. Invalids have often preferred this plant to the Scurvy grass as an antiscorbutic remedy. In the warm summer months the flowers have been observed about the time of sunset to give out sparks, as of an electrical kind, which were first noticed by a daughter of Linnoeus.
The Water-cress is justly popular with persons who drink freely overnight, for its power of dissipating the fumes of the liquor, and of clearing away lethargic inaptitude for work in the morning: also for dispelling the tremors, and the foul taste induced by excessive tobacco smoking.
Closely allied thereto is another cruciferous plant, the Scurvy grass (Cochleare), named also "Spoon-wort" from its leaves resembling in shape the bowl of an old-fashioned spoon. This is thought to be the famous Herba Britannica of the ancients. Our great navigators have borne testimony to its never failing use in scurvy, and, though often growing many miles from the sea, yet the taste of the herb is always [134] found to be salt. If eaten in its fresh state, as a salad, it is the most effectual of all the antiscorbutic plants, the leaves being admirable also to cure swollen and spongy gums. It grows along the muddy banks of the Avon, likewise in Wales, and is found in Cumberland, more commonly near the coast; and again on the mountains of Scotland. It may be readily cultivated in the garden for medicinal use.
The Cuckoo flower, or "Ladies' Smock" (Cardamine) from Cardia damao, "I strengthen the heart," is another wholesome Cress with the same sensible properties as the Water-cress, only in an inferior degree, while the strong pungency of its flavour prevents it from being equally popular. This plant bears also the names of "Lucy Locket," and "Smell Smocks." In Cornwall the flowering tops have been employed for the cure of epilepsy throughout several generations with singular success; though the use of the leaves only for this purpose has caused disappointment. From one to three drams of these flowering tops are to be taken two or three times a day.
By the Rev. Mr. Gregor (1793) and by his descendants this remedy was given for inveterate epilepsy with much benefit. Lady Holt, and her sister Lady Bracebridge, of Aston Hall, Warwickshire, were long famous for curing severe cases of the same infirmity by administering this herb. They gave the powdered heads of the flowers when in full bloom-twelve grains three times a day for many weeks together.
Sir George Baker in 1767 read a paper before the London College of Physicians on the value of these flowers in convulsive disorders. He related five cures of St. Vitus' dance, spasmodic convulsions, and spasmodic asthma. Formerly the flowers were admitted into the [135] London Pharmacopoeia. The herb was named Ladies' Smock in honour of the Virgin Mary, because it comes first into flower about Lady Day, being abundant with its delicate lilac blossoms in our moist meadows and marshes:
"Lady Smocks all silver white
Do paint the meadows with delight."
This plant is also named—"Milk Maids," "Bread and Milk," and "Mayflower." Gerard says "it flowers in April and May when the Cuckoo cloth begin to sing her pleasant notes without stammering." One of his characters is made by the Poet Laureate to—
"Steep for Danewulf leaves of Lady Smock,
For they keep strong the heart."
