Myrrh has been fully described among the tonics. (See vol. i. p. 304.) Though I confess that I cannot bear a strong personal testimony to the emmenagogue properties of this medicine; yet the general medical opinion, which has so long maintained it among the standard remedies in amenorrhoea, can scarcely have been quite mistaken. it is used under circumstances similar to those which call for the chalybeates, and is very often associated with them; but is more especially adapted to cases in which amenorrhoea is conjoined with chronic pectoral disease. For its dose and modes of administration, I must content myself with referring to former articles on the subject. (See as above, i. 304.) it is almost always given in combination with other medicines, and forms an ingredient in a considerable number of officinal preparations, used with a view, partly at least, to the emmenagogue effect. See Compound Decoction of Aloes (II. 531); Compound Mixture of iron (i. 451); Pills of Aloes and Myrrh (II. 530); Compound Pills of iron (i. 451); and Compound Galbanum Pills (i. 603).
