All-Spice (_Pimento_) is another common occupant of the domestic spice box. It is popular as a warming cordial, of a sweet odour, and a grateful aromatic taste; but being a native of South America, grows with us only as a stove plant. The leaves and bark are full of inflammable particles, whilst walks between Pimento trees are odorous with a delicious scent. The name All-Spice is given because the berries afford in smell and taste a combination of Cloves, Juniper berries, Cinnamon and Pepper. The special qualities of the Pimento reside in the rind of these berries; and this tree is the _Bromelia ananas_, [397] named in Brazil Nana. An extract made from the crushed berries by boiling them down to a thick liquor, is, when spread on linen, a capital stimulating plaster for neuralgic or rheumatic parts. About the physician in "les Francais" it was said admiringly "c'est lui qui a invente la salade d'Ananas." The essential oil, as well as the spirit and the distilled water of Pimento, are useful against flatulent indigestion and for hysterical paroxysms. This Spice was formerly added to our syrup of buckthorn to prevent it from griping. The berries are put into curry powder, and added to mulled wines. OAT. The Oat is a native of Britain in its wild and uncultivated form, and is distinguished by the spikelets of its ears hanging on slender pedicels. This is the _Avena fatua_, found in our cornfields, but not indigenous in Scotland. When cultivated it is named _Avena sativa_. As it needs less sunshine and solar warmth to ripen the grain than wheat, it furnishes the principal grain food of cold Northern Europe. With the addition of some fat this grain is capable of supporting life for an indefinite period. Physicians formerly recommended highly a diet-drink made from Oats, about which Hoffman wrote a treatise at the end of the seventeenth century; and Johannis de St. Catherine, who introduced the drink, lived by its use to a hundred years free from any disease. Nevertheless the Oat did not enjoy a good reputation among the old Romans; and Pliny said "Primum omnis frumenti vitium avena est." American doctors have taken of late to extol the Oat (_Avena sativa_) when made into a strong medicinal tincture with spirit of wine, as a remarkable nervine stimulant and restorative: this being "especially valuable in [398] all cases where there is a deficiency of nervous power, for instance, among over-worked lawyers, public speakers, and writers."
