||Ornamental flower. As an herb, it was believed by the Chinese to have the power of life. Legend has it that the boiled roots were used as a headache remedy; young sprouts and petals were eaten in salads; and leaves were brewed for a festive drink.
||Chrysanthemums contain a variety of allergens including sesquiterpene lactones. The allergens are borne on the surface of the flowers and leaves, often in the trichomes (plant hairs) which means that they can easily become airborne.
||Contact dermatitis from chrysanthemum often starts on the fingertips (from removing flower buds) but usually spreads to the forearms and face. It can sometimes be very persistent and has been associated with the development of chronic actinic dermatitis (a severe form of photosensitivity dermatitis). Chrysanthemums are the commonest cause of occupational dermatitis to compositae plants, affecting horticulturalists and florists, but many amateur gardeners are also at risk. Contact urticaria has also been reported following exposure to chrysanthemums; this is an itchy rash occurring within minutes of direct contact with the plant, which settles within an hour or so.
||If you are allergic to chrysanthemums, you unfortunately must remove all chrysanthemums and other members of the Asteraceae (Compositae) family from both your house and garden because even tiny quantities of the allergen in the pollen can cause a reaction on exposed skin.
