Rubbing, gently stroking the part which is the seat of the active pain, will not infrequently secure prompt relief from suffering. This is especially true in the case of headache, pain in the joints, and in some cases of neuralgia and muscular rheumatism. Many popular liniments owe their efficacy almost wholly to the friction with which they are applied. It is well known that a liniment does no good unless it is well rubbed in. A remedy which many years ago was very popular for the relief of pain consisted wholly of olive-oil with the addition of a little beeswax. Gentle stroking of the head and spine will often give more complete relief in severe nervous headache and general nervous irritability than any other remedy which can be applied.
