Pimenta dioica

FAMILY Myrtaceae

SYNONYMS P. officinalis, pimento, pimenta, Jamaica pepper.

GENERAL DESCRIPTION An evergreen tree which reaches about 10 metres high and begins to produce fruit in its third year. Each fruit contains two kidney-shaped green seeds which turn glossy black upon ripening.

DISTRIBUTION Indigenous to the West Indies and South America, it is cultivated extensively in Jamaica, Cuba and, to a lesser degree, in Central America. Imported berries are distilled in Europe and America.

OTHER SPECIES Four other varieties of pimento are found in Venezuela, Guyana and the West Indies which are used locally as spices.

HERBAL/FOLK TRADITION Used for flatulent indigestion and externally for neuralgic or rheumatic pain. Pimento water is used as a vehicle for medicines which ease dyspepsia and constipation since it helps prevent griping pains. It is used extensively as a domestic spice – allspice is so called because it tastes like a combination of cloves, juniper berries, cinnamon and pepper.

ACTIONS Anaesthetic, analgesic, anti-oxidant, antiseptic, carminative, muscle relaxant, rubefacient, stimulant, tonic.

EXTRACTION Essential oil by steam distillation from 1. the leaves, and 2. the fruit. The green unripe berries contain more oil than the ripe berries, but the largest percentage of oil is contained in the shell of the fruit. An oleoresin from the berries is also produced in small quantities.

CHARACTERISTICS 1. Pimenta leaf oil is a yellowish-red or brownish liquid with a powerful sweet-spicy scent, similar to cloves. 2. Pimenta berry oil is a pale yellow liquid with a sweet warm balsamic-spicy bodynote (middle note) and fresh, clean top note. It blends well with ginger, geranium, lavender, opopanax, labdanum, ylang ylang, patchouli, neroli, oriental and spicy bases.

PRINCIPAL CONSTITUENTS Mainly eugenol, less in the fruit (60–80 per cent) than in the leaves (up to 96 per cent), also methyl eugenol, cineol, phellandrene and cryophyllene among others.

SAFETY DATA Eugenol irritates the mucous membranes, and has been found to cause dermal irritation. Pimenta leaf and berry oil should therefore be used with care in low dilutions only.

AROMATHERAPY/HOME USE Circulation, muscles and joints: Arthritis, fatigue, muscle cramp, rheumatism, stiffness etc. ‘Used in tiny amounts … in a massage oil for chest infections, for severe muscle spasm to restore mobility quickly, or where extreme cold is experienced.’¹

Respiratory System: Chills, congested coughs, bronchitis.

Digestive System: Cramp, flatulence, indigestion, nausea.

Nervous System: Depression, nervous exhaustion, neuralgia, tension and stress.

OTHER USES Used in aromatic carminative medicines; as a fragrance component in cosmetics and perfumes, especially soaps, aftershaves, spicy and oriental fragrances. Both leaf and berry oil are used extensively for flavouring foods, especially savoury and frozen foods, as well as alcoholic and soft drinks.
