In making lemonade it is a mistake to pour boiling water upon sliced Lemons, because thus brewing an infusion of the peel, which is medicinal. The juice should be squeezed into cold water (previously boiled), adding to a quart of the same the juice of three lemons, a few crushed strawberries, and the cut up rind of one Lemon.
This fruit grows specially at Mentone, in the south of France; and a legend runs that Eve carried two or three Lemons with her away from Paradise, wandering about until she came to Mentone, which she found to be so like the Garden of Eden that she settled there, and planted her fruit.
The special dietetic value of Lemons consists in their potash salts, the citrate, malate, and tartrate, which are respectively antiscorbutic, and of assistance in promoting biliary digestion. Each fluid ounce of the fresh juice contains about forty-four grains of citric acid, with gum, sugar, and a residuum, which yields, when incinerated, potash, lime, and phosphoric acid. But the citric acid of the shops is not nearly so preventive or curative of scurvy as the juice itself.
The exterior rind furnishes a grateful aromatic bitter; and our word "zest" signifies really a chip of lemon peel or orange peel used for giving flavour to liquor. It comes from the Greek verb, "skizein," to divide, or cut up.
The juice has certain sedative properties whereby it allays hysterical palpitation of the heart, and alleviates pain caused by cancerous ulceration of the tongue. Dr. Brandini, of Florence, discovered this latter property of fresh Lemon juice, through a patient who, when suffering [302] grievously from that dire disease, found marvellous relief to the part by casually sucking a lemon to slake his feverish thirst. But it is a remarkable fact that the acid of Lemons is harmful and obnoxious to cats, rabbits, and other small animals, because it lowers the heart's action in these creatures, and liquifies the blood; whereas, in man it does not diminish the coagulability of the blood, but proves more useful than any other agent in correcting that thin impoverished liquidity thereof which constitutes scurvy. Rapin extols lemons, or citrons, for discomfort of the heart:—
"Into an oval form the citrons rolled
Beneath thick coats their juicy pulp unfold:
From some the palate feels a poignant smart,
Which, though they wound the tongue, yet heal the heart."
Throughout Italy, and at Rome, a decoction of fresh Lemons is extolled as a specific against intermittent fever; for which purpose a fresh unpeeled Lemon is cut into thin slices, and put into an earthenware jar with three breakfastcupfuls of cold water, and boiled down to one cupful, which is strained, the lemon being squeezed, and the decoction being given shortly before the access of fever is expected.
For a restless person of ardent temperament and active plethoric circulation, a Lemon squash (unsweetened) of not more than half a tumblerful is a capital sedative; or, a whole lemon may be made hot on the oven top, being turned from time to time, and being put presently when soft and moist into a teacup, then by stabbing it about the juice will be made to escape, and should be drunk hot. If bruised together with a sufficient quantity of sugar the pips of a fresh Lemon or Orange will serve admirably against worms in [303] children. Cut in slices and put into the morning bath, a Lemon makes it fragrant and doubly refreshing.
Professor Wilhelm Schmole, a German doctor, has published a work of some note, in which he advances the theory that fresh Lemon juice is a kind of elixir vitae; and that if a sufficient number of Lemons be taken daily, life may be indefinitely prolonged. Lemon juice is decidedly beneficial against jaundice from passive sluggishness of the biliary functions; it will often serve to stay bleedings, when ice and astringent styptics have failed; it will prove useful when swallowed freely against immoderately active monthly fluxes in women; and when applied externally it signally relieves cutaneous itching, especially of the genitals.
Prize-fighters refresh themselves with a fresh cut Lemon between the rounds when competing in the Ring. Hence has arisen the common saying, "Take a suck of the Lemon, and at him again."
