Is indoor flower cultivation harmful to human body?

The advantages and disadvantages of indoor flowers and plants can not be generalized, but should be selected scientifically. Most plants release oxygen at the same time of photosynthesis in daytime, but at night, because respiration is far greater than photosynthesis, they inhale a lot of oxygen and exhale a lot of carbon dioxide, which leads to competition for oxygen with people. So many plants are not suitable for the bedroom at night. However, in cactus and many succulent plants (such as longevity flower (Ailanthus altissima), aloe, Lysimachia christinae, Sedum, Celosia, etc.). ), the stomata are closed during the day, and the oxygen produced during the day is released at night. Therefore, putting it in the bedroom is beneficial to increase the indoor oxygen content, and at the same time, it can release negative ions, which can timely supplement the indoor negative ion content caused by TV and computer use.

In addition, many plants have a strong ability to absorb toxic gases, such as aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum, Dendrocalamus, etc., which can absorb a variety of toxic gases, especially formaldehyde. Ivy, cycad, chrysanthemum, kumquat, pomegranate, mirabilis jalapa, Scutellaria barbata, rose, camellia, pomegranate, Milan, daisy, Chimonanthus praecox and marigold have their own advantages in resisting harmful gases such as sulfur dioxide, fluorine, chlorine, ether, ethylene, mercury vapor, lead vapor, carbon monoxide and nitrogen peroxide. The volatile oil produced by fragrant flowers such as rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and crape myrtle has obvious bactericidal effect. However, all plants will release harmful gases, some of which are toxic and some are too pungent to be kept indoors, such as oleander, yellow oleander, Datura flower, cordate telosma, evergreen, narcissus, tulip and lily.

In addition, 52 kinds of plants that are said to cause cancer should also be avoided indoors: stone millet, variable leaf wood, variable leaf wood, banyan tree, croton, bone-seeking wind, croton, unicorn crown, cat's eye, Euphorbia helioscopia, kansui, Euphorbia lathyrifera, Schizonepeta, osmanthus fragrans, cockscomb and Eichhornia crassipes.
