Preparation.—"Resin cerate, six hundred and fifty grammes (650 Gm.) [1 lb. av., 6 ozs., 406 grs.]; oil of turpentine, three hundred and fifty grammes (350 Gm.) [12 ozs. av., 151 grs.]; to make one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]. Melt the resin cerate in a capsule, on a water-bath, then add the oil of turpentine, and mix them thoroughly"—(U. S. P).
This is Kentish liniment. In its preparation a low heat should be employed to melt the cerate, after which the oil may be added gradually with constant stirring.
Action and Medical Uses.—This was at one time highly praised as an application to burns and scalds. It should be applied as soon as possible after the accident, and be allowed to remain on for at least a day. It should be applied on lint, care being taken to keep it from contact with the sound tissues. After healthy granulations set in, it should be discontinued. It may be employed in erythematous and erysipelatous conditions, when superficial or arising from injury, and in frost-bites.
