Which plants are good for the body and which are harmful?

Placing chlorophytum, asparagus and tortoise shell bamboo indoors can absorb toxic and harmful gases such as carbon dioxide, sulfur dioxide and formaldehyde, and eliminate and reduce air pollution.

chemistry

Pollution and resistance to microbial invasion. Such as chlorophytum can absorb carbon monoxide and formaldehyde; Araceae can absorb benzene and trichloroethylene in the air. Dianthus caryophyllus, a perennial herb, commonly known as "Dianthus caryophyllus has an iron stomach, which can clean up toxic gas" and has the ability to absorb sulfur dioxide and chloride; Roses and roses can absorb harmful gases such as hydrogen sulfide, hydrogen fluoride, phenol and ether. If you put a pot of pomegranate flowers in the room, you can see both flowers and fruits, which can reduce the lead content in the air; Rutaceae plants such as Kumquat, Four Seasons Orange and Cinnabar Orange are rich in oil bracts, which can inhibit bacteria, prevent mold and prevent colds. Evergreen, which is very popular with people, contains a toxic enzyme, which can drive away cockroaches indoors. Jasmine, chrysanthemum and other flowers have miraculous effects on relieving dizziness, dizziness, cold, stuffy nose and blurred vision.

Zhou, an engineer at the Indoor Environmental Monitoring Center of China Decoration Association, believes that the following two types of plants are most suitable for indoor use.

Plants that can absorb toxic chemicals.

Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum are natural scavengers, which can remove harmful substances in the air. Studies show that Eupatorium adenophorum and Eupatorium adenophorum can absorb more than 80% of indoor harmful gases, and their ability to absorb formaldehyde is super strong. Aloe vera is also a good hand at absorbing formaldehyde, which can absorb 90% formaldehyde contained in 1 m3 air.

Ivy, cycad, chrysanthemum, kumquat, pomegranate, Scutellaria barbata, rose, camellia, pomegranate, Milan, daisy, Chimonanthus praecox, marigold, etc. can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide and nitrogen peroxide.

Orchids, osmanthus fragrans, wintersweet, cauliflower taro and osmanthus fragrans are natural dust collectors, and their cilia can intercept and absorb suspended particles and smoke in the air.

Plants that can kill bacteria

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 sterilization effect.

Crape myrtle, jasmine, lemon and other plants can kill diphtheria, dysentery bacteria and other protobacteria within 5 minutes. The scents of roses, carnations, lilies of the valley, violets, roses, osmanthus flowers and other plants have obvious inhibitory effects on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus.

Cactus and other succulent plants originated in tropical arid areas, the stomata on their succulent stems are closed during the day and opened at night, which absorbs carbon dioxide and produces oxygen at the same time, increasing the concentration of negative ions in indoor air.

Plants such as Hupilan, Huweilan, Tequila, Palm, Kale, Sedum, Rooting and Pineapple can also purify the night air.

Climbing plants such as Parthenocissus tricuspidata, grape, morning glory, wisteria, rose, etc. Planting around the house can make it climb along the wall or along the shelf to form a green arbor, which can effectively reduce sunlight radiation and greatly reduce the indoor temperature.

Lilac, jasmine, rose, violet, mint and other plants can make people relax, feel happy, help sleep and improve work efficiency.

Flowers and trees containing carcinogens.

China Center for Disease Control and Prevention pointed out that some common ornamental flowers and trees in families and parks, such as begonia, mutual leaves, tallow, sweet-scented osmanthus and tung trees, all contain cancer-promoting substances, which will promote the growth of cancer cells when encountered. If these plants are planted at home, people will induce cancer by inhaling pollen and root dust for a long time. At the same time, some people think that soil with cancer-promoting plants also contains cancer-promoting substances. If you eat the fruits and vegetables planted next to you for a long time, it may also be harmful to your health.

Although there are 52 kinds of flowers and trees containing cancer-promoting substances in China, there are only more than 20 kinds in Shanghai, and even fewer are planted at home. Pay more attention to shopping in the future, and there will be no problem.
