Nasturtium

Definition and stakes

William Thomas Fernie,  Herbal Simples Approved for Modern Uses of Cure

“ The Latin name Nasturtium was given to the Watercress because of its volatile pungency when bruised and smelt; from nasus, a nose, and tortus, turned away, it being so to say, "a herb that wriths or twists the nose." For the same reason it is called Nasitord in France. When bruised its leaves affect the eyes and nose almost like mustard. They have been usefully applied to the scald head and tetters of children. In New Zealand the stems grow as thick as a man's wrist, and nearly choke some of the rivers. Like an oyster, the Water-cress is in proper season only when there is an "r" in the month. ”

the Elder Pliny,  The Natural History of Pliny, Volume 4…

“ Applied with leaven it brings boils1536 to a head, and makes carbuncles suppurate and break: used with honey, too, it is good for cleansing phagedænic ulcers. Topical applications are made of it, combined with vinegar and polenta, in cases of sciatica and lumbago: it is similarly employed, too, for lichens and malformed1537 nails, its qualities being naturally caustic. The best nasturtium of all is that of Babylonia; the wild1538 variety possesses the same qualities as the cultivated in every respect, but in a more powerful degree. ”

Jane Newell Moore,  Outlines of Lessons in Botany, Part I; from Seed to Leaf

“ The leaves droop and close together at night, protecting them from being chilled by too great radiation.
The cause of these movements is believed to lie in changes of tension preceding growth in the tissues of the stem. [1] Every stem is in a state of constant tension. Naudin has thus expressed it, "the interior of every stem is too large for its Jacket." [2] If a leaf-stalk of Nasturtium be slit vertically for an inch or two, the two halves will spring back abruptly. This is because the outer tissues of the stem are stretched, and spring back like india-rubber when released.
