Medicated soaps are made by adding the drug to either hard soap or curd soap in the desired proportions.
Medicated soaps, first investigated scientifically by Unna of Hamburg in 1886, contain certain substances which exercise a specific influence on the skin.
A few medicated soaps are prepared for internal use, among which are croton soap and jalap soap, both gentler cathartics than the uncompounded medicinal principles.
Medicated soaps for external use are only employed in cases of skin ailments, as prophylactic washes and as disinfectant soaps.
Trees must be fixed to the walls and buildings against which they are trained by means of nails and shreds (neat medicated strips are now sold for this purpose), or in cases where it is desired to preserve the wall surface intact, by permanent nails or studs driven in in regular order.
When shreds and nails are used, short thick wire nails and " medicated shreds " are the best; the ordinary cast iron wall nails being much too brittle and difficult to drive into the wall.
"The waters are medicated in a manner through the intervention of the angel, and the Spirit is corporeally washed in the water and the flesh is spiritually purified in the same."
Flavoured syrups are made by adding flavouring matter to a simple syrup. For instance, syrupus aromaticus is prepared by adding certain quantities of orange and cinnamon water to simple syrup. Similarly, medicated syrups are prepared by adding medicaments to, or dissolving them in, the simple syrup. Golden syrup is the uncrystallizable fluid drained off in the process of obtaining refined crystallized sugar.
It is also worked up in certain medicated soaps.
