Dracaena, lily family, appears among the anti-pollution plants together with the ficus benjamina, philodendron and other plants used to fight the air pollution in houses and rooms. Doctor B. Wolverton, who worked for NASA, studied, in the ‘70s and ‘80s, the role of plants in transforming the primordial Earth's atmosphere in a hospitable place for life. He identified 50 plants that are particularly effective against toxic and polluting substances, among these the plants of Liliaceae family, such as precisely the dracaena, have been found to be particularly active. The name of this plant derives from the greek Drakaina, female dragon, for the fact that, from a species of dracaena, the dracaena draco, is extracted a resin used to obtain a dye called dragon's blood. The Dracaena, in all its variants, is very useful to remove formaldehyde, a carcinogenic substance widespread and used in the manufacture of synthetic resins, glues, solvents, disinfectants, cosmetics, textiles and particle boards, benzene, released from the cigarette smoke or combustion of chimneys, stoves, candles or incense but also contained in glues, new furnishings, printers and copiers, and trichlorethylene, which is contained in paints, dyes, lubricants, solvents. In particular, the dracaena massangeana is particularly effective against formaldehyde (able to absorb 70% of this substance), also acts against the benzene (absorbs 21.4% of it), while the dracaena dermensis warneckei and marginata are very useful against benzene (the level of absorption of the substance is 70%) and against formaldehyde (around 50%). All three species absorb a percentage of around 15% of trichlorethylene. This plant prefers bright environments but without direct light exposure, watering is regular during the summer months, less frequent in the winter months. Dracaena should be placed away from air currents and from sudden drastic temperature changes. Pay attention if you have dogs or cats at home, try to place this plant so that it is difficult for them to reach as it can be toxic if eaten.
Able to purify the environments and to absorb most of carcinogens and pollutants that can be found at home or office, such as formaldehyde, benzene and trichlorethylene.
