A glance at this list shows exactly the class of cases in which suggestion has always played a large role, and for which there has been, at various times, a series of specific remedies, medicinal, manipulative and surgical. Others extended the value of the moxa beyond these affections. Ponto found it valuable in gout, and in the various chronic affections which are sometimes grouped under the name chronic rheumatism. He insisted that the moxa could be placed on almost any part of the body, though the contra indications he suggests show how far the men of his time went with its use. Only these portions named might not have a moxa applied to them. It must not be used on the skull, on the eyelids, on the ears, on the mamme, on the larynx and on the genitals, though it might be applied to the perineum or the perineal body. Deterrent Taste and Smell.--The disturbing effects produced by other senses besides those of sight have been used in the same way for the production of definite therapeutic suggestive effects. A number of the ill-tasting, almost nauseating drugs of the olden time prove to have very little real therapeutic efficiency in the light of modern clinical careful observation. This is particularly true of the herbs and simples. Many a disgusting preparation apparently owed all of its' good effects on the patient to the effort that was required to swallow it, producing such a favorable influence upon the mind, by _contrecoup_ as it were, that the patient got better. A little girl said that cough medicines were nasty things they gave you in order to keep you from catching cold again. The sense of smell has been used in the same way. Valerian is probably an efficient drug in certain respects, but undoubtedly its efficiency is materially increased by its intensely repulsive odor. For many of the psycho-neuroses and neurotic conditions generally the ammonium valerianate is likely to be much more efficient than the strychnin valerianate, though probably the {69} latter should be considered as more physically efficacious in its tonic properties. Asafetida, musk and some preparations of the genital organs of animals that used to be in the pharmacopeia, owed most, if not all, of their power, whatever it was, to the mental effect of their odor and the feeling of deterrence that had to be overcome before they were taken.
