Father don Antonio Julian wrote: "This plant is a preventive against many diseases, a restorative of lost strength, and is capable of prolonging human life. It is sincerely to be regretted that so many poor families do not possess this preventive of hunger and thirst; that so many employees and laborers should be deprived of this means of maintaining their strength in the midst of continuous toil; that so many old and young men engaged in the arduous task of study and the accomplishment of their undertakings are unable to derive the beneficial results of this plant to guard against the exhaustion of the vital spirits, debility of the brain, and weakness of the stomach, which are frequent results of continuous study." Böerhaave (_Inst. phys._ § 68), states that: "the saliva charged with all the bitter and mucilaginous principles of Coca carries to the stomach, in addition to vital strength, a veritable nutritive which, digested and converted into an abundant and nutritious chyle, enters into the circulation and is converted into the material necessary to sustain the human economy." We shall not stop to quote the different writings of observers who have interested themselves in Coca. It may be inferred from the preceding statements that Coca possesses this particular character, viz., of enabling those who make use of it to withstand the greatest fatigue. Men employed in hard work in mines, couriers obliged to traverse mountainous countries difficult of travel without being able to take much rest, in a word, persons subject to overwork in every way, all agree in recognizing the strengthening and nerve-fortifying action of Coca. It supports them, economizes their forces, prevents their succumbing to lassitude—in short, augments their vitality. When the Indian has a good supply of Coca he undertakes, without the slightest fear, the most difficult and longest voyages, even into fever-stricken countries. When he passes before an _apachecta_ (a quadrangular mound which the natives raise on the sides of the roads at certain points for a halting-place), the Indian divests himself of his wraps, takes his quid of Coca from his mouth, always after having previously exhausted it, and, in order to draw down upon it the blessing of Pachacamac, their sovereign master of the world, he throws it against the consecrated hillock. Thus, that which particularly characterizes these kinds of _tumuli_ are the green splashes of Coca with which they are literally covered. The name of _coqueros_ is given to the chewers of Coca. It seems that this plant procured for them dreams like those to which hachisch gives rise. In native therapeutics, this plant is used to dress ulcers and all kinds of sores. The Indians also use it to combat asthma, jaundice, colic, etc.
