Chocolate. This is prepared by roasting the seeds of the Cacoa, or Cocoa, then grinding them and forming them into cakes. “Chocolate, though devoid of the disagreeable qualities of tea and coffee, which disturb the nervous functions, yet is difficult of digestion, on account of the large quantity of oil which it contains, and is, therefore, very apt to disturb the stomach of dyspeptics.”
Cocoa. This is made of the nuts and husks of the cocoa, roasted and ground, and is somewhat less oily than chocolate, and being rather astringent, is adapted to looseness of the bowels. The shells alone are often used to make a drink, which is less rich than the Cocoa, and especially adapted to weak digestive powers.
The seeds of the vegetable called Ochra, roasted and prepared like coffee, are said to equal it in flavor.
3. Acidulous Drinks.
“The employment of vegetable acid, as an aliment, is necessary to health. It seems pretty clearly established, that complete and prolonged abstinence from succulent vegetables, or fruits, or their preserved juices, as articles of food, is a cause of scurvy.”
“Water, sharpened with vegetable acids, oftentimes proves a most refreshing beverage, allaying thirst, and moderating excessive heat. Various acids form cooling, refreshing, and antiscorbutic drinks, and are well adapted for hot seasons, and for febrile and inflammatory cases.”
These drinks are prepared by dissolving vegetable acids or acidulous salts in water, sweetening and flavoring it. Also, by decoctions of acid fruits, which promote secretions in the alimentary canal, and act as laxatives.
The carbonated or effervescing drinks belong to this class. They owe their sparkling briskness to carbonic acid gas confined in the liquid.
4. Drinks containing Gelatine and Osmazome.
Gelatine is that part of animal and vegetable matter that forms jelly.
