SUBSTANCES CAUSING ALLERGIES
Tobacco
Smoking may create or aggravate existing respiratory allergy because cigarettes may contain (besides tobacco) many potentially allergenic ingredients, such as licorice and molasses.
An allergic person, child or adult, should avoid small rooms and enclosed spaces where crowds gather and smoke (such as the smoking section of movie houses) because hot tobacco smoke is a nonspecific irritant besides being a potential allergen.
Pyrethrum
Pyrethrum is a powder prepared from the dried flower of the pyrethrum plant, which is related to the ragweed plant. It is used as an insecticide to spray plants in backyards or in moth killers to preserve winter clothing and carpeting.
These fibers are used for filling life preservers (because they remain afloat for hours without much absorption of water); for insulation purposes; and for less expensive sleeping bags and mattresses. (Kapok was used in the past as a filling for pillows to avoid highly allergenic feathers. However, this practice has now stopped because of the development of foam rubber, plastics, and synthetic fibers.) Kapok seeds provide an oil used in making soap and in the preparation of certain foods.
Flax
Flax is the Latin word for the linen plant which provides linseed oil and linen fibers. Linseed oil may cause allergies when eaten, inhaled, or touched, and linen fibers may cause eczema and rashes when they are used in clothing.
Flax fibers, seeds, or oil may be inhaled when one is near flaxseed meal (which is a food given to cattle and poultry) ; in beauty salons and barber shops (as some wave sets, shampoos, and hair tonics (Kreml) may contain it); using bird lime, carron oil, flaxseed poultices, furniture polish, linseed oil, paints, varnishes, linoleum, printer’s and lithographic ink, some soft soaps, and some depilatories; or using damask, table linen, cambric, handkerchief linen, toweling, oilcloth, and sewing thread.
