Commiphora myrrha. Almost universally official. C. Africana, Bdellium, official in France and Spain. The action is due to a volatile oil, which is carminative, stimulant, and tonic in small doses, and in large doses a gastric irritant. It is excreted by the mucous membranes, thus giving expectorant and uterine influences.


Myrrh stimulates indolent ulcers and eczema when applied externally. The tincture is used in dilution. The undiluted tincture is applied to ulcerated gums, aphthous patches, and relaxed conditions of the uvula, pharynx, and in ptyalism. It is an ingredient of dentifrices.

Internally it is employed in bronchorrea, and sometimes in tuberculosis. It is combined with purgatives of the aloe type to modify the action. Atonic dyspepsia is often favorably influenced by myrrh; it is commonly combined with bitters in this indication. In the treatment of amenorrhea, it is combined with iron or aloes.

Myrrh is given in doses of 2 to 10 grains. The tincture is effective in 10- to 20-minim doses; tincture aloes and myrrh in twice this dosage.
