Description
The bushes yielding the resin do not grow more than 9 feet
in height, but they are of sturdy build, with knotted branches, and branchlets
that stand out at right-angles, ending in a sharp spine. The trifoliate leaves
are scanty, small and very unequal, oval and entire. It was first recognized
about 1822 at Ghizan on the Red Sea coast, a district so bare and dry that
it is called 'Tehama,' meaning 'hell.'
Botanically, there is still uncertainty about the origin and identity of the
various species.
There are ducts in the bark, and the tissue between them breaks down, forming
large cavities, which, with the remaining ducts, becomes filled with a granular
secretion which is freely discharged when the bark is wounded, or from natural
fissures. It flows as a pale yellow liquid, but hardens to a reddish-brown
mass, being found in commerce in tears of many sizes, the average being that
of a walnut. The surface is rough and powdered, and the pieces are brittle,
with a granular fracture, semi-transparent, oily, and often show whitish marks.
The odour and taste are aromatic, the latter also acrid and bitter. It is
inflammable, but burns feebly.
Several species are recognized in commerce. It is usually imported in chests
weighing 1 or 2 cwts., and wherever produced comes chiefly from the East Indies.
Adulterations are not easily detected in the powder, so that it is better
purchased in mass, when small stones, senegal gum, chestnuts, pieces of bdellium,
or of a brownish resin called 'false myrrh,' may be sorted out with little
difficulty.
It has been used from remote ages as an ingredient in incense, perfumes, etc.,
in the holy oil of the Jews and the Kyphi of the Egyptians for embalming and
fumigations.
Little appears to be definitely known about the collection of myrrh. It seems
probable that the best drug comes from Somaliland, is bought at the fairs
of Berbera by the Banians of India, shipped to Bombay, and there sorted, the
best coming to Europe and the worst being sent to China. The true myrrh is
known in the markets as karam, formerly called Turkey myrrh, and the opaque
bdellium as meena harma.
The gum makes a good mucilage and the insoluble residue from the tincture
can be used in this way.

---Constituents---Volatile oil, resin (myrrhin), gum, ash, salts, sulphates,
benzoates, malates, and acetates of potassa.
It is partially soluble in water, alcohol, and ether. It may be tested by
a characteristic violet reaction if nitric acid diluted with an equal volume
of water is brought into contact with the residue resulting from the boiling
of 0.1 gramme of coarsely powdered myrrh with 2 c.c. of 90 per cent alcohol,
evaporated in a porcelain dish so as to leave a thin film.
The oil is thick, pale yellow, and contains myrrholic acid and heerabolene,
a sesquiterpenene.
---Medicinal Action and Uses---Astringent, healing. Tonic and stimulant. A
direct emmenagogue, a tonic in dyspepsia, an expectorant in the absence of
feverish symptoms, a stimulant to the mucous tissues, a stomachic carminative,
exciting appetite and the flow of gastric juice, and an astringent wash.
It is used in chronic catarrh, phthisis pulmonalis, chlorosis, and in amenorrhoea
is often combined with aloes and iron. As a wash it is good for spongy gums,
ulcerated throat and aphthous stomatitis, and the tincture is also applied
to foul and indolentulcers. It has been found helpful in bronchorrhoea and
leucorrhoea. It has also been used as a vermifuge.
When long-continued rubefacient effect is needed, a plaster may be made with
1 1/2 OZ. each of camphor, myrrh, and balsam of Peru rubbed together and added
to 32 OZ. of melted lead plaster, the whole being stirred until cooling causes
it to thicken.
Myrrh is a common ingredient of toothpowders, and is used with borax in tincture,
with other ingredients, as a mouth-wash.
The Compound Tincture, or Horse Tincture, is used in veterinary practice for
healing wounds.
Meetiga, the trade-name of Arabian Myrrh, is more brittle and gummy than that
of Somaliland and has not its white markings.
The liquid Myrrh, or Stacte, spoken of by Pliny, and an ingredient of Jewish
holy incense, was formerly obtainable and greatly valued, but cannot now be
identified.

---Other Species---
Bissa Bôl, or perfumed bdellium of theArabs, has an odour like mushrooms.
Though it is sent from Arabian ports to India and China, it was formerly known
as East Indian Myrrh. It is of a dark colour, and may be a product of Commiphora
erythraea, var. glabrescens, of B. Kalaf, A. Kafal, B. Playfairii or Hemprichia
erythraea.
B. Kua of Abyssinia has been found to yield Myrrh.
Mecca balsam, a product of B. or C. Opobalsamum, is said to be the Myrrh of
the Bible, the Hebrew word mar having been confused with the modern Arabic
morr or Myrrh in translation.
Bdellium, recognized as an inferior Myrrh and often mixed with or substituted
for it, is a product of several species of Commiphora, according to American
writers, or Balsamodendron according to English ones. Four kinds are collected
in Somaliland, making sub-divisions of African Bdellium:
Perfumed Bdellium or Habaghadi, African Bdellium, Opaque Bdellium, Hotai Bdellium.
These African bdelliums, said by some writers to be products of Balsamodendron
(Heudelotia) Africanum, are in irregular, hard, roundish tears about an inch
in diameter, pale yellow to red-brown, translucent, the fracture waxy, taste
and odour slight.
The product of Ceradia furcata is also called African Bdellium.
The commercial Gugul, or Indian Bdellium, is said by some writers to be a
product of Commiphora roxburghiana, by others of B. Mukul, and by others again
of B. roxbhurghii or Amyris Bdellium. It is more moist than Myrrh; is found
in irregular, dark reddishbrown masses, with a waxy fracture; softens with
the heat of the hand; adheres to the teeth when chewed; and smells slightly
of Myrrh.
It is used in the East Indies in leprosy, rheumatism and syphilis, and in
Europe for plasters. [Top]
