ASTRINGENTS _with_ TONICS. A combination of certain medicines belonging to these two classes is frequently indicated; in the treatment of passive hemorrhage, we have to astringe the bleeding vessels, and, at the same time, to cure the hemorrhagic diathesis by remedies which are capable of restoring the general tone of the system. In the treatment of the chronic and humid coughs of old persons, I have very frequently witnessed the beneficial union of the warm and stimulating influence of _Myrrh_ with the astringent effects of _Sulphate of Zinc_. _Form. 69_ presents the combination which I have usually adopted with success on such occasions. DIURETICS _with_ TONICS. As Dropsy is frequently associated with great debility, the practitioner should combine his diuretics with some tonic medicine; but in forming a judgment upon the case he must be guided by those precepts which have been laid down under the consideration of Diuretics at page 97. See _Form. 114_. DIURETICS _with_ AROMATIC STIMULANTS. Such a combination will be found advantageous in those cases where the powers of the system require to be excited by more prompt measures than those afforded by the agency of tonics. _Ethereal_ preparations, with Squill and other stimulating diuretics, are well calculated upon such occasions to afford valuable assistance. _Form. 101–116._ TONICS _with_ DIFFUSIBLE STIMULANTS. In the cure of dyspepsia, we frequently require a remedy, for the purpose of obviating debility, that is more sudden in its action, and prompt in its effects, than that of a bitter _tonic_, whose operation is almost imperceptible; while the case may at the same time stand in need of that permanent increase of tone, which the latter remedy can alone supply; such an indication therefore must be fulfilled by combination. _Form. 40, 42._
