Myrrh. The gum-resinous exudation from the stem of Balsamodendron (Protium) Myrrha. Nat. Ord, Terebinthaceae. Linn. Syst. Octandria Monogynia. Source, Abyssinia and Arabia Felix.

Med. Prop. and Action. Stimulant, expectorant, and emmenagogue, in doses of gr. x. - gr. xx. In these doses it acts as a stimulant of the digestive organs, and improves the appetite. In doses of 388., Cullen found it cause a burning sensation in the stomach, increased arterial excitement, and profuse diaphoresis, and, like other medicines of the same class, it exercised a great influence on the urinary passages. It also appears to possess the power of diminishing profuse discharges from mucous membranes, particularly from the pulmonary and genito-urinary organs. Its operation as an expectorant is greatly increased by combining it with Squills, &c, and as an emmenagogue, by the addition of Aloes or Iron. The Tincture is of great value as a gargle, &c., when diluted with water, or some astringent infusion.

1857. Therapeutic Uses

In AmenorrhAea, Myrrh has long been held in high esteem. By itself, its power is very limited; but, in combination with Iron and Aloes, it appears to impart to those medicines an activity which they do not possess when given singly. It is an important constituent in Mist. Ferri Co., and Pil. Ferri Co. (Ph. L.). In Chlorosis and Leucorrha, it appears to exercise a beneficial influence.

1858. In Bronchitis Of Long Standing, Dr

Williams states* that he has found Myrrh a very valuable medicine, particularly after a course of expectorants, when its grateful and tonic effects upon the stomach give it an additional recommendation. It is inadmissible when any fever or irritability is present.

1859. In the Asthma of old Persons, Myrrh has been found very useful in arresting the exhaustion consequent on profuse expectoration.

1860. In Phthisis, it was formerly held in high esteem, but, it appears, undeservedly so. In the latter stages, however, when there is great debility, with profuse expectoration, its tonic and stimulant properties entitle it to a fair trial. It is an important constituent in Griffith's celebrated Anti-hectic Mixture (Mist. Ferri Co.).

1864. To foul and indolent Ulcers, the diluted tincture has been used as a stimulating wash.
