[571] The first mention of this fruit by the London Horticultural Society occurred in 1818.
Chemically in addition to the acids already named the Tomato contains a volatile oil, a brown resinous extractive matter very fragrant, a vegeto-mineral matter, muco-saccharin, some salts, and in all probability an alkaloid. The whole plant smells unpleasantly, and its juices when subjected to heat by the action of fire emit a vapour so powerful as to provoke vertigo and vomiting.
The specific principles furnished by the Tomato will, when concentrated, produce, if taken medicinally, effects very similar to those brought about by taking mercurial salts, viz., an ulcerative-state of the mouth, with a profuse flow of saliva, and with excessive stimulation of the liver: peevishness also on the following day, with a depressing backache in men, suggesting paralysis, and with a profuse fluor albus in women. When given in moderation as food, or as physic, the fruit will remedy this chain of symptoms.
By reason of its efficacy in promoting an increased flow of bile if judiciously taken, the Tomato bears the name in America of Vegetable Mercury, and it has almost superseded calomel there as a biliary medicinal provocative. Dr. Bennett declares the Tomato to be the most useful and the least harmful of all known medicines for correcting derangements of the liver. He prepares a chemical extract of the fruit and plant which will, he feels assured, depose calomel for the future.
Across the Atlantic an officinal tincture is made from the Tomato for curative purposes by treating the apples, and the bruised fresh plant with alcohol, and letting this stand for eight days before it is filtered and strained.
A teaspoonful of the tincture is a sufficient dose with one or two tablespoonfuls of cold water, three times in the day.
[572] The fluid extract made from the plant is curative of any ulcerative soreness within the mouth, such as nurses' sore mouth, or canker. It should be given internally, and applied locally to the sore parts.
Spaniards and Italians eat Tomatoes with pepper and oil. We take them as a salad, or stewed with butter, after slicing and stuffing them with bread crumb, and a spice of garlic.
The green Tomato makes a good pickle, and in its unripe state is esteemed an excellent sauce with rich roast pork, or goose. The fruit when cooked no longer exercises active medicinal effects, as its volatile principles have now become dispelled through heat.
By the late Mr. Shirley Hibberd, who was a good naturalist, it was asserted with seeming veracity that the cannibal inhabitants of the Fiji Islands hold in high repute a native Tomato which is named by them the Solanum anthropophagorutm, and which they eat, par excellence, with "Cold Missionary." Nearer home a worthy dame has been known with pious aspirations to enquire at the stationer's for "Foxe's book of To-Martyrs."
