The flowers occur in long, hanging, inconspicuous spikes or catkins, of a brownish green colour.
This tree is a native of Asia Minor, but is largely grown in England. The Greeks called it "Karuon," and the Latins "Nux." Its botanical title is Juglans regia, a corruption of glans, the acorn, jovis, of Jupiter, or the "royal nut of Jupiter," food fit for the Gods! Its fruit is also named Ban nut, or Ball nut, and Welsh nut, or Walnut— the word Wal, or Welsh, being Teutonic for "stranger." "As for the timber," said Fuller, "it may be termed the English Shittim Wood."
[598] The London Society of Apothecaries has directed that the unripe fruit of the Walnut should be used pharmaceutically on account of its worm-destroying virtues.
It is remarkable that no insects will prey on the leaves of this tree. In good seasons the produce of nuts is weighty enough to pay the rent of the land occupied by the trees.
The vinegar of the pickled fruit makes a very useful gargle for sore throats, even when slightly ulcerated: and the green husks, or early buds of the blossom, being dried to powder, serve in some places for pepper.
The kernel of the nut (or the part of the inside taken at dessert) affords an oil which does not congeal by cold, and which painters find very useful on such account.
This oil has proved useful when applied externally for troublesome skin diseases of the leprous type. Indeed, the Walnut has been justly termed vegetable arsenic, because of its curative virtues in eczema, and other obstinately diseased conditions of the skin.
The tincture when made (H.) from the rind of the green fruit and the fresh leaves, with spirit of wine, and given in material doses, will determine in a sound person a burning itching eruption of the skin, of an eczematous character, lasting a long time, and leaving the parts which have been affected afterwards blue and swollen. Reasoning from which it has been found that the tincture, in a reduced form, and of a diminished strength, proves admirably curative of eczema, impetigo, and ecthyma.
The unripe fruit is laxative, and of beneficial use in thrush, and in ulcerative sore throat. The leaves are said to be anti-syphilitic: likewise the green husk, and unripe shell. Obstinate ulcers may be cured with sugar well moistened in a strong decoction of the leaves.
[599] Well kept, kiln-dried Walnuts, of some age, are better digested than newer fruit; in contrast to old gherkins, about which it has been humorously said, "avoid stale Q-cumbers: they will W-up." In many parts of Germany the peasants literally subsist on Walnuts for several months together; and a young farmer before he marries has to own a certain number of flourishing Walnut trees.
