The art of medicine among the Sumatrans consists almost entirely in the application of simples, in the virtues of which they are well skilled. Every old man and woman is a physician, and their rewards depend upon their success; but they generally procure a small sum in advance under the pretext of purchasing charms.* The mode of practice is either by administering the juices of certain trees and herbs inwardly, or by applying outwardly a poultice of leaves chopped small upon the breast or part affected, renewing it as soon as it becomes dry. For internal pains they rub oil on a large leaf of a stimulant quality, and, heating it before the fire, clap it on the body of the patient as a blister, which produces very powerful effects. Bleeding they never use, but the people of the neighbouring island of Nias are famous for their skill in cupping, which they practise in a manner peculiar to themselves.
(*Footnote. Charms are there hung about the necks of children, as in Europe, and also worn by persons whose situations expose them to risk. They are long narrow scrolls of paper, filled with incoherent scraps of verse, which are separated from each other by a variety of fanciful drawings. A charm against an ague I once accidentally met with, which from circumstances I conclude to be a translation of such as are employed by the Portuguese Christians in India. Though not properly belonging to my subject, I present it to the reader. "(Sign of the cross). When Christ saw the cross he trembled and shaked; and they said unto him hast thou an ague? and he said unto them, I have neither ague nor fever; and whosoever bears these words, either in writing or in mind, shall never be troubled with ague or fever. So help thy servants, O Lord, who put their trust in thee!" From the many folds that appear in the original I have reason to apprehend that it had been worn, and by some Englishmen, whom frequent sickness and the fond love of life had rendered weak and superstitious enough to try the effects of this barbarous and ridiculous quackery.)
FEVERS.
In fevers they give a decoction of the herb lakun, and bathe the patient, for two or three mornings, in warm water. If this does not prove effectual, they pour over him, during the paroxysm, a quantity of cold water, rendered more chilly by the daun sedingin (Cotyledon laciniata) which, from the sudden revulsion it causes, brings on a copious perspiration. Pains and swellings in the limbs are likewise cured by sweating; but for this purpose they either cover themselves over with mats and sit in the sunshine at noon, or, if the operation be performed within doors, a lamp, and sometimes a pot of boiling herbs, is enclosed in the covering with them.
LEPROSY.
There are two species of leprosy known in these parts. The milder sort, or impetigo, as I apprehend it to be, is very common among the inhabitants of Nias, great numbers of whom are covered with a white scurf or scales that renders them loathsome to the sight. But this distemper, though disagreeable from the violent itching and other inconveniences with which it is attended, does not appear immediately to affect the health, slaves in that situation being bought and sold for field and other outdoor work. It is communicated from parents to their offspring, but though hereditary it is not contagious. I have sometimes been induced to think it nothing more than a confirmed stage of the serpigo or ringworm, or it may be the same with what is elsewhere termed the shingles. I have known a Nias man who has effected a temporary removal of this scurf by the frequent application of the golinggang or daun kurap (Cassia alata) and such other herbs as are used to cure the ringworm, and sometimes by rubbing gunpowder and strong acids to his skin; but it always returned after some time. The other species with which the country people are in some instances affected is doubtless, from the description given of its dreadful symptoms, that severe kind of leprosy which has been termed elephantiasis, and is particularly described in the Asiatic Researches Volume 2, the skin coming off in flakes, and the flesh falling from the bones, as in the lues venerea. This disorder being esteemed highly infectious, the unhappy wretch who labours under it is driven from the village he belonged to into the woods, where victuals are left for him from time to time by his relations. A prang and a knife are likewise delivered to him, that he may build himself a hut, which is generally erected near to some river or lake, continual bathing being supposed to have some effect in removing the disorder, or alleviating the misery of the patient. Few instances of recovery have been known. There is a disease called the nambi which bears some affinity to this, attacking the feet chiefly, the flesh of which it eats away. As none but the lowest class of people seem to suffer from this complaint I imagine it proceeds in a great degree from want of cleanliness.
SMALLPOX.
The smallpox (katumbuhan) sometimes visits the island and makes terrible ravages. It is regarded as a plague, and drives from the country thousands whom the infection spares. Their method of stopping its progress (for they do not attempt a cure) is by converting into a hospital or receptacle for the rest that village where lie the greatest number of sick, whither they send all who are attacked by the disorder from the country round. The most effectual methods are pursued to prevent any person's escape from this village, which is burnt to the ground as soon as the infection has spent itself or devoured all the victims thus offered to it. Inoculation was an idea long unthought of, and, as it could not be universal, it was held to be a dangerous experiment for Europeans to introduce it partially, in a country where the disorder makes its appearance at distant intervals only, unless those periods could be seized and the attempts made when and where there might be well-founded apprehension of its being communicated in the natural way. Such an opportunity presented itself in 1780, when great numbers of people (estimated at a third of the population) were swept away in the course of that and the two following years; whilst upon those under the immediate influence of the English and Dutch settlements inoculation was practised with great success. I trust that the preventive blessing of vaccination has or will be extended to a country so liable to be afflicted with this dreadful scourge. A distemper called chachar, much resembling the smallpox, and in its first stages mistaken for it, is not uncommon. It causes an alarm but does not prove mortal, and is probably what we term the chickenpox.
VENEREAL DISEASE.
The venereal disease, though common in the Malay bazaars, is in the inland country almost unknown. A man returning to his village with the infection is shunned by the inhabitants as an unclean and interdicted person. The Malays are supposed to cure it with the decoction of a china-root, called by them gadong, which causes a salivation.
