IGE-MEDIATED REACTIONS

As Nutmeg and Mace are integrally related, this article should be read in conjunction with Nutmeg Rf282. Mace may uncommonly induce symptoms of food allergy or cutaneous hypersensitivity reactions in sensitised individuals. Few studies have investigated or reported adverse reactions to spices, including Mace. The composition of Mace may depend upon its country of origin and also on the quality of the Mace harvest. Therefore, the occurrence of antigens and the incidence of Mace allergy may vary among different Mace preparations, which may influence the prevalence and severity of allergic reactions.

Occupational asthma and rhinitis was documented in a 27-year-old subject who developed rhinitis and asthma symptoms 1 year after starting to prepare a certain kind of sausage. This was demonstrated by positive immediate skin-specific IgE tests for Paprika, Coriander, and Mace. Skin-specific IgE for other sausage ingredients (mites, pollens, and molds) was negative. Serum-specific IgE antibodies to Paprika, Coriander, and Mace were manifest, and a partial cross-reactivity was found among IgE-binding components from Paprika and Mace. Specific bronchial inhalation challenges showed an immediate asthmatic reaction to extracts from Paprika, Coriander, and Mace. In this patient, occupational asthma was due to spices from botanically unrelated species.

Occupational asthma and rhinitis to licorice (dust), Mace, Aniseed, Coriander and iris root in an Anise liqueur factory worker were reported.

An individual working with spices in the food industry developed asthma on inhalation of dust from spices. Skin-specific IgE tests with Curry, Coriander, and Mace were strongly positive. Serum-specific IgE antibodies against Coriander, Curry, Mace, Ginger, and Paprika powder could be demonstrated in the patient’s serum. The authors concluded that the inhalation of dust from spices can result in an IgE-mediated allergy to these materials.

It may well be that, similar to Nutmeg, Mace's predominant pathogenesis involves delayed-hypersensitivity reactions.

In the cuisines of Asia, Nutmeg and Mace are traditional ingredients of a variety of dishes, such as curries. In Western cuisine, Nutmeg and Mace are used in cakes, crackers and stewed fruits. Nutmeg is used to flavour drinks such as eggnog, and in fondue and béchamel (white sauce). Nutmeg oil is, moreover, an additive in a wide range of commercial foods and medicines, especially colas. The more aromatic Mace is a frequent ingredient of sausages and other prepared meats. Both Nutmeg and Mace are used to relieve digestive ailments.

Nutmeg contains up to 10% essential oil, which can be toxic. The component myristicin (methoxy-safrole) is responsible for the hallucinogenic effect of Nutmeg. Oil of Mace (up to 12% in the spice) contains the same aroma components in slightly different amounts. Apparently only excessive ingestion of either spice, however, can produce hallucinogenic or toxic effects.

Nutmeg on expression yields about 24 to 30 percent fixed oil called Nutmeg butter or oil of Mace, the principal component of which is trimyristin. The oils are used as condiments and flatulence treatments and to scent soaps and perfumes. An ointment of Nutmeg butter is used as a treatment for topical irritations and rheumatism.
