(MYRISTICA FRAGRANS, FAM. MYRISTICACEAE)
It grows in Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana.
The tree is about 25 feet high, has a grayish-brown smooth bark, abounding in a yellow juice. The branches spread in whorls – alternate leaves, on petioles about 1 inch long, elliptical, glabrous, obtuse at base – acuminate, aromatic, dark green and glossy above, paler underside and 4 to 6 inches long.
Flowers dioecious, small in axillary racemes. Male flowers three to five more on a peduncle. Calyx urceolate, thick and fleshy, covered with an indistinct reddish pubescence dingy pale yellow, cut into three erect teeth.
Female flowers differ little from the male, except pedicel is often solitary. Fruit is a pendulous, globose drupe, consisting of a succulent pericarp – the mace arillus covering the hard endocarp, and a wrinkled kernel with ruminated endosperm.
When the arillus is fresh it is a brilliant scarlet, when dry more horny, brittle, and a yellowish-brown colour. The seed or nutmeg is firm, fleshy, whitish, transversed by red-brown veins, abounding in oil.
The tree does not bloom till it is nine years old, when it fruits and continues to do so for seventy-five years without attention. In Banda Islands there are three harvests, the chief one in July or August, the next in November, and the last in March or April.
The fruit is gathered by means of a barb attached to a long stick. The mace is separated from the nut and both are dried separately. The nutmeg or kernel of the fruit and the arillus or mace are the official parts.
After the mace is removed, the nutmegs are dried on gratings, three to six weeks over a slow charcoal fire – but are often sun-dried for six days previously. The curing protects them from insects.
When thoroughly dried, they rattle in the shell, which is cracked with a mallet. The nutmegs are graded, 1st Penang, 2nd Dutch (these are usually covered with lime to preserve them from insects), 3rd Singapore, and 4th long nutmegs.
Nutmegs have a strong, peculiar and delightful fragrance and a very strong bitter warm aromatic taste.
Dried kernel of the seed.
They contain lignin, stearin, volatile oil, starch, gum and 0.08 of an acid substance. By submitting nutmegs and water to distillation, a volatile oil is obtained. The small round heavy nutmeg is the best. Those that are larger, longer, lighter, less marbled, and not so oily, are inferior.
The powder of nutmegs, beaten to a pulp with water, then pressed between heated plates, gives from 10 to 30 per cent of orange colored scented concrete oil erroneously called ‘oil of mace’ – an inferior oil is prepared in Holland from the spoiled or inferior nutmegs – and an artificial preparation is made by mixing together tallow, spermaceti, etc., coloring it with saffron and flavoring it with essential oil of nutmeg.
After the nutmegs have been collected, the outside fleshy pericarp is made into a preserve.
The mace of commerce should be somewhat flexible, cinnamon-yellow coloured, in single or double blades, with nutmeg-like smell and a warm, sharp, fatty, aromatic taste.
There is much adulteration and fraud in the nutmeg trade. The essential oil has often been extracted before they are marketed – a fraud which can be detected by the lightweight. This renders them more subject to attacks by insects.
Concrete oil of nutmeg, often erroneously termed ‘oil of mace’ or ‘nutmeg butter,’ is made by bruising the nuts and treating them with steam. The best nutmeg butter is imported from the East Indies in stone jars, or in blocks wrapped in palm leaves – it should be softly solid, unctuous to touch, orange yellow colour and mottled, with the taste and smell of nutmeg.
Holland prepares an inferior kind of oil sometimes offered for sale – it is said to be derived from nutmegs that have been deprived of their volatile oil by distillation.
It is found in hard shining square cakes, light coloured and with less taste and smell than the East Indies oil. Almost colorless with a fresh smell of nutmeg, it contains myristin, olein, and otobite. Insects that attack nutmegs only extract the fat oil. They do not interfere in any way with the essential oil.
MEDICINAL ACTION AND USES:
The tonic principle is Myristicin. Oil of Nutmeg is used to conceal the taste of various drugs and as a local stimulant to the gastro-intestinal tract.
USES OF NUTMEG:
Powdered nutmeg is rarely given alone, though it enters into the composition of a number of medicines. The expressed oil is sometimes used externally as a gentle stimulant, and it was once an ingredient of the Emplastrum picis.
The properties of mace are identical to those of the nutmeg. Dose: 5 to 20 grains.
Both nutmeg and mace are used for flatulence and to correct the nausea arising from other drugs, also to allay nausea and vomiting.
Nutmeg is an agreeable addition to drinks for convalescents. Grated nutmeg mixed with lard makes an excellent ointment for piles.
In some places roasted nutmeg is applied internally as a remedy for leucorrhoea. Dose of the powder: 5 to 20 grains. Fluid extract, 10 to 30 drops. Larger doses are narcotic and produce dangerous symptoms. Spirit, B.P., 5 to 20 drops.
Stimulant, slight narcotic.
1. Sublingually take the seed powder, 0,5 g four times a day, every six hours. Keep the powder for 15-20 minutes, and then swallow it with some water and some natural honey.
2. Prepare a bitter, stimulant and light drink from nutmeg, anise, and Collubria elliptica.
3. Volatile oil, 2-3 drops, 2-3 times a day, with natural honey.
4. As a spice, especially in heavy meals, the nutmeg favors digestion and increases appetite. Its use is frequent, especially with sweets.
IMPORTANT NOTE: In great quantities, the nutmeg is intoxicating, so avoid any excesses. It gives a state of euphoria with delirium and even it can provokes death.
