[Mozo here describes certain remedies for sickness which are used by the natives. Among these are the gall and fat of the python (called saua and biting, in various dialects) and another similar species of serpent, which reach an enormous size in the forests of the interior. The gall is used both internally and externally by the natives, to cure chills and pains in the stomach--to which they are especially liable from going barefooted, and more or less naked, through mud and rain at all times; also for malignant fevers and any inflammation which causes them. Mozo relates how he had cured himself of a high fever, when the physicians had "sentenced him to death," by the use of this remedy, and had on other occasions been relieved or cured by it; "consequently, I guard what I have of it like a precious jewel." The fat of these serpents is equally efficient for swellings or pains in the muscles and sinews, especially those caused by chills and exposure to weather; also it relieves the pains of gout.] [Those Indians used a small stone, resembling a nut, in order to facilitate childbirth; they said that it was found, although only in small quantities, in a mine somewhere; this stone, applied to the left thigh, would quickly relieve the most difficult case of parturition, [55] and afterward, applied again, would bring away the placenta; but in both cases it must be removed as soon as the desired effect was accomplished, or else it would "cause even the bowels to be drawn out." They also made use of a certain root, called in the Pampanga tongue sugapa, [56] to inflame their courage in battle; "he who eats it is made beside himself, and rendered so furious that while its effect lasts he cares not for dangers, nor even hesitates to rush into the midst of pikes and swords. On many occasions, therefore, when they go out to fight with any who are hostile to them they are wont to carry this root with them, and, by eating it at the time of the attack, they enter the battle like furious wild beasts, without turning back even when their force is cut to pieces; on the other hand, even when one of them is pierced from side to side with a lance, he will raise himself by that very lance in order to strike at him who had pierced him. Sometimes, also, when they wish to revenge themselves on some more powerful man, it occurs to them to eat the said root; and, with the fury which it arouses in them, they fling themselves upon him like rabid wolves, being carried away by that rage in the presence of the person whom they meet, whoever he may be. Therefore, on account of the pernicious effects which the said root causes, the Dutch have given peremptory orders in Batavia that any person who sees another, whoever he may be, in the said fury shall without fail shoot him or [otherwise] put him to death, in order that an end may be put to the fatal accidents which are daily seen in that city, on account of the natives there being very prone to this barbarous proceeding.
