MYRRH

Commiphora myrrha

FAMILY Burseraceae

SYNONYMS
Balsamodendrom myrrha
, gum myrrh, common myrrh, hirabol myrrh, myrrha.

GENERAL DESCRIPTION The
Commiphora
species which yield myrrh are shrubs or small trees up to 10 metres high. They have sturdy knotted branches, trifoliate aromatic leaves and small white flowers. The trunk exudes a natural oleoresin, a pale yellow liquid which hardens into reddish-brown tears, known as myrrh. The native collectors make incisions in the bark of the tree to increase the yield.

DISTRIBUTION The
Commiphora
species are native to north east Africa and south west Asia, especially the Red Sea region (Somalia, Yemen and Ethiopia).

OTHER SPECIES There are several C. species which yield myrrh oleoresin: African or Somali myrrh
(C. molmol)
and Arabian or Yemen myrrh
(C. abyssinica).
Bisabol myrrh or opopanax
(C. erthraea)
also belongs to the same family.

HERBAL/FOLK TRADITION Myrrh has been employed since the earliest times in Eastern and Western medicine; its use is mentioned some 3700 years ago. The ancient Egyptians used it for embalming purposes and in their perfumes and cosmetics. In China it is used for arthritis, menstrual problems, sores and haemorrhoids. In the West it is considered to have an ‘opening, heating, drying nature’ (Joseph Miller), good for asthma, coughs, common cold, catarrh, sore throat, weak gums and teeth, ulcers and sores. It has also been used to treat leprosy.

Current in the British Herbal Pharmacopoeia as a specific for mouth ulcers, gingivitis and pharyngitis.

ACTIONS Anticatarrhal, anti-inflammatory, antimicrobial, antiphlogistic, antiseptic, astringent, balsamic, carminative, cicatrisant, emmenagogue, expectorant, fungicidal, revitalizing, sedative, stimulant (digestive, pulmonary), stomachic, tonic, uterine, vulnerary.

EXTRACTION 1. Resinoid (and resin absolute) by solvent extraction of the crude myrrh. 2. Essential oil by steam distillation of the crude myrrh.

CHARACTERISTICS 1. The resinoid is a dark reddish-brown viscous mass, with a warm, rich, spicy-balsamic odour. It is not pourable at room temperature so a solvent, such as diethyl phthalate, is sometimes added. 2. The essential oil is a pale yellow to amber oily liquid with a warm, sweet-balsamic, slightly spicy-medicinal odour. It blends well with frankincense, sandalwood, benzoin, oakmoss, cypress, juniper, mandarin, geranium, patchouli, thyme, mints, lavender, pine and spices.

PRINCIPAL CONSTITUENTS The crude contains resins, gum and about 8 per cent essential oil composed mainly of heerabolene, limonene, dipentene, pinene, eugenol, cinnamaldehyde, cuminaldehyde, cadinene, among others.

SAFETY DATA Non-irritant, non-sensitizing, possibly toxic in high concentration. Not to be used during pregnancy.

(Myrica cerifera)
and the Dutch myrtle or English bog myrtle
(Myrica gale)
which are used in herbal medicine (though their essential oils are said to be poisonous). Not to be confused with iris, sometimes called ‘myrtle flower’ or calamus, which is also known as ‘myrtle grass’ or ‘sweet myrtle’.

HERBAL/FOLK TRADITION The leaves and berries have been used for ‘drying and binding, good for diarrhoea and dysentery, spitting of blood and catarrhous defluctions upon the breast’.
60

N
NARCISSUS

Narcissus poeticus

FAMILY Amaryllidaceae

SYNONYMS Pinkster lily, pheasant’s eye, poet’s narcissus.

GENERAL DESCRIPTION A familiar garden flower up to 50 cms high, with long sword-shaped leaves with very fragrant white flowers having a short yellow trumpet and crisped red edge.

DISTRIBUTION Native to the Middle East or the eastern Mediterranean region; naturalized in southern France. It is cultivated extensively for its flowers. Only Holland and the Grasse region of France produce the concrete and absolute.

OTHER SPECIES There are two main types produced in France: the cultivated or
des plaines
variety and the wild or
des montagnes
type. Narcissus is also closely related to the jonquil
(N. jonquilla)
and campernella
(N. odorus)
, which are also occasionally used to produce an absolute, as well as to the daffodil
(N. pseudo-narcissus).

HERBAL/FOLK TRADITION The name derives from the Greek
narkao
– to be numb – due to its narcotic properties. The Roman perfumers used ‘narcissum’, a solid unguent made from narcissus flowers, in the preparation of their elaborate fragrances. In France the flowers were used at one time for their antispasmodic properties, said to be useful in hysteria and epilepsy.

In India the oil is applied to the body before prayer in temples, along with rose, sandalwood and jasmine. The Arabians recommend the oil as a cure for baldness, and as an aphrodisiac.

ACTIONS Antispasmodic, aphrodisiac, emetic, narcotic, sedative.

EXTRACTION A concrete and absolute by solvent extraction from the flowers.

CHARACTERISTICS The absolute is a dark orange, olive or green viscous liquid with a sweet, green-herbaceous odour and heavy floral undertone. It blends well with clove bud, jasmine, neroli, ylang ylang, rose, mimosa, sandalwood, oriental and floral fragrances.

PRINCIPAL CONSTITUENTS Quercetin, possibly narcissine (the alkaloid that causes nausea).

SAFETY DATA All members of the Amaryllidaceae family, especially the bulbs, have a profound effect on the nervous system, causing paralysis and even in some cases death. ‘The bulbs of N.
poeticus
are more dangerous than those of the daffodil, being powerfully emetic and irritant. The scent of the flowers is deleterious, if they are present in any quantity in a closed room, producing in some persons headache and even vomiting.’
62

AROMATHERAPY/HOME USE Perfume.

OTHER USES The absolute and concrete are used almost exclusively in high class perfumes of the narcotic/ floral type.

NIAOULI

Melaleuca viridiflora

FAMILY Myrtaceae

SYNONYMS
M. quinquenervia
, ‘gomenol’.

GENERAL DESCRIPTION An evergreen tree with a flexible trunk and spongy bark, pointed linear leaves and bearing spikes of sessile yellowish flowers. The leaves have a strong aromatic scent when they are crushed.

DISTRIBUTION Native to Australia, New Caledonia, and the French Pacific Islands. The majority of the oil is produced in Australia and Tasmania.

OTHER SPECIES A typical member of the ‘tea tree’ group of oils; the oil is similar to cajeput. There is another physiological form of
M. viridiflora
called ‘Variety A’, which was originally developed to provide a natural source of nerolidol, the main constituent of its essential oil.

HERBAL/FOLK TRADITION It is used locally for a wide variety of ailments, such as aches and pains, respiratory conditions, cuts and infections; it is also used to purify the water. The name ‘gomenol’ derives from the fact that it used to be shipped from Gomen in the French East Indies.

ACTIONS Analgesic, anthelmintic, anticatarrhal, antirheumatic, antiseptic, antispasmodic, bactericidal, balsamic, cicatrisant, diaphoretic, expectorant, regulator, stimulant, vermifuge.

EXTRACTION Essential oil by steam distillation from the leaves and young twigs. (Usually rectified to remove irritant aldehydes.)

CHARACTERISTICS A colourless, pale yellow or greenish liquid with a sweet, fresh, camphoraceous odour.

PRINCIPAL CONSTITUENTS Cineol (50–65per cent), terpineol, pinene, limonene, citrene, terebenthene, valeric ester, acetic ester, butyric ester.

SAFETY DATA Non-toxic, non-irritant, non-sensitizing. Often subject to adulteration.

AROMATHERAPY/HOME USE

SKIN CARE:
Acne, boils, burns, cuts, insect bites, oily skin, spots, ulcers, wounds.

CIRCULATION, MUSCLES AND JOINTS
: Muscular aches and pains, poor circulation, rheumatism.

IMMUNE SYSTEM
: Colds, fever, ’flu.

OTHER USES Used in pharmaceutical preparations such as gargles, cough drops, toothpastes, mouth sprays, etc.

NUTMEG

Myristica fragrans

FAMILY Myristicaceae

SYNONYMS
M. officinalis, M. aromata, Nux moschata
, myristica (oil), mace (husk), macis (oil).

GENERAL DESCRIPTION An evergreen tree up to 20 metres high with a greyish-brown smooth bark, dense foliage and small dull-yellow flowers. ‘Mace’ is the name given to the bright red netlike aril or husk surrounding the nutmeg shell and seed, which is contained within the fleshy fruit.

DISTRIBUTION Native to the Moluccas and nearby islands; cultivated in Indonesia, Sri Lanka and the West Indies, especially Grenada.

The oil is also distilled in the USA and Europe from the imported nutmegs.

OTHER SPECIES Indonesia and Sri Lanka produce the so-called ‘East Indian’ nutmeg which is considered superior, while Grenada produces the ‘West Indian’ nutmeg – see also Botanical Classification.

HERBAL/FOLK TRADITION Nutmeg and mace are widely used as domestic spices in the East and West. They have been used for centuries as a remedy mainly for digestive and kidney problems. In Malaysia they are used during pregnancy to strengthen and tone the uterine muscles. Grated nutmeg with lard is used for piles. A fixed oil of nutmeg is also used in soap and candle making.

Nutmeg is current in the British Herbal Pharmacopoeia indicated for flatulent dyspepsia, nausea, diarrhoea, dysentery, and topically for rheumatism.

ACTIONS Analgesic, anti-emetic, anti-oxidant, antirheumatic, antiseptic, antispasmodic, aphrodisiac, carminative, digestive, emmenagogue, gastric secretory stimulant, larvicidal, orexigenic, prostaglandin inhibitor, stimulant, tonic.

EXTRACTION Essential oil by steam (or water) distillation from 1. the dried worm-eaten nutmeg seed (the worms eat away all the starch and fat content); 2. the dried orange-brown aril or husk – mace; and 3. an oleoresin is also produced in small quantities by solvent extraction from mace.

CHARACTERISTICS 1. A water-white or pale yellow mobile liquid with a sweet, warm-spicy odour and a terpeney top-note. 2. A water-white or pale yellow mobile liquid with a sweet, warm-spicy scent. 3. An orange-brown viscous liquid with a fresh, spicy-warm, balsamic fragrance. It has good masking power.

They blend well with oakmoss, lavandin, bay leaf, Peru balsam, orange, geranium, clary sage, rosemary, lime, petitgrain, mandarin, coriander and other spice oils.

PRINCIPAL CONSTITUENTS Mainly monoterpene hydrocarbons (88 per cent approx.): camphene, pinene, dipentene, sabinene, cymene, with lesser amounts of geraniol, borneol, linalol, terpineol, myristicin (4–8 per cent), safrol and elemincin, among others. Mace oil contains similar constituents but contains more myristicin.

SAFETY DATA Both nutmeg and mace are generally non-toxic, non-irritant and non-sensitizing. However, used in large doses they show signs of toxicity such as nausea, stupor and tachycardia, believed to be due to the myristicin content. ‘Large quantities are hallucinogenic and excitant to the motor cortex.’
63
On this basis nutmeg (especially the West Indian type) is probably safer to use than mace. Use in moderation, and with care in pregnancy.

AROMATHERAPY/HOME USE

CIRCULATION, MUSCLES AND JOINTS
: Arthritis, gout, muscular aches and pains, poor circulation, rheumatism.

DIGESTIVE SYSTEM:
Flatulence, indigestion, nausea, sluggish digestion.

IMMUNE SYSTEM
: Bacterial infection.

NERVOUS SYSTEM
: Frigidity, impotence, neuralgia, nervous fatigue.

OTHER USES Used as a flavouring agent in pharmaceuticals, especially analgesic and tonic preparations. Nutmeg and mace oil are used in soaps, lotions, detergents, cosmetics and perfumes. Mace oleoresin is used in colognes and perfumes, especially men’s fragrances. Both oils and oleoresin are used in most major food categories, including alcoholic and soft drinks.
