OIL BATH.
Inunction was greatly practiced by the ancients in connection with the Roman and Turkish baths. It consists in rubbing the skin very thoroughly with some unctuous substance. Olive oil may be employed, but cosmoline or vaseline, two refined products of coal oil, are in some respects preferable. Olive oil cannot be obtained pure, except at almost fabulous prices. That sold in the drug stores as olive oil is really cotton-seed oil and mixtures of lard with various other vegetable oils.
A warm bath should first be administered. Then dry the patient, as usual, and apply the unguent, taking care to rub it in thoroughly. Simply greasing the surface is not the object sought. The skin and flesh should be worked, rubbed, and kneaded until the oil nearly disappears from the surface.
The object of this application is to supply the place of defective natural secretion of oleaginous material, to increase the activity of the skin, and to diminish susceptibility to cold. How this is accomplished, readily appears. The oil is a simple substitute for the sebaceous secretion, which is, in a certain class of diseases, notably deficient. The thorough manipulation of the skin which is necessary in applying the oil, and which is facilitated by a lubricant, directly promotes cutaneous activity. Whether the oil itself has any direct effect in increasing the functional activity of the skin cannot be positively affirmed, although it is reasonably supposable that the skin will act more nearly normal when a deficient element is supplied than when it is wanting. Oil is an excellent non-conductor; and invalids who are especially susceptible to cold may be rendered comfortable by the application of the oil bath.
The class of cases to which this remedy is applicable will be sufficiently well indicated by the purposes which the bath is supposed to subserve. It should not be used indiscriminately. Once or twice a week is sufficiently often to make the application, and each should be followed by a warm bath with fine soap, two or three days after.
