{"Image DocumentName": "LIST OF AIR-FILTERING PLANTS", "Image ImageDescription": "Chrysanthemums, often called mums or chrysanths, are of the genus (Chrysanthemum) constituting approximately 30 species of perennial flowering plants in the family Asteraceae which is native to Asia and northeastern Europe. Modern chrysanthemums are much more showy than their wild relatives. The flowers occur in various forms, and can be daisy-like, decorative, pompons or buttons. This genus contains many hybrids and thousands of cultivars developed for horticultural purposes. In addition to the traditional yellow, other colors are available, such as white, purple, and red. The most important hybrid is Chrysanthemum \u00d7 morifolium (syn. C. \u00d7 grandiflorum), derived primarily from C. indicum but also involving other species. Pyrethrum (Chrysanthemum [or Tanacetum] cinerariaefolium) is economically important as a natural source of insecticide. The flowers are pulverized, and the active components called pyrethrins, contained in the seed cases, are extracted and sold in the form of an oleoresin. This is applied as a suspension in water or oil, or as a powder. Pyrethrins attack the nervous systems of all insects, and inhibit female mosquitoes from biting. When not present in amounts fatal to insects, they still appear to have an insect repellent effect. They are harmful to fish, but are far less toxic to mammals and birds than many synthetic insecticides, except in consumer airborne backyard applications. They are non-persistent, being biodegradable and also breaking down easily on exposure to light. They are considered to be amongst the safest insecticides for use around food. (Pyrethroids are synthetic insecticides based on natural pyrethrum, e.g., permethrin.) Chrysanthemum plants have been shown to reduce indoor air pollution by the NASA Clean Air Study. Extracts of Chrysanthemum plants (stem and flower) have been shown to have a wide variety of potential medicinal properties, including anti-HIV-1, antibacterial and antimycotic.
