What plants should be kept in the dormitory?

Not all plants are suitable for indoor use, so when choosing indoor plants, we must distinguish them. Only healthy plants can be invited in. And all this, we must fully understand the relationship between indoor plants and human health in advance.

Aloe, chlorophytum, Eupatorium odoratum, Eupatorium odoratum and Dendrocalamus giganteum are natural scavengers. The research shows that aloe vera, Eupatorium odoratum and chlorophyllin have strong absorption ability to indoor harmful gas formaldehyde. Cycas evergreen, chrysanthemum, kumquat, pomegranate, mirabilis jalapa, Scutellaria barbata, rose, camellia, Milan, daisy, wintersweet and marigold can absorb harmful gases emitted by household appliances and plastic products. The volatile oils of rose, osmanthus fragrans, violet, jasmine, lemon, rose, carnation, lily of the valley and Lagerstroemia indica have obvious bactericidal effect. Crape myrtle, jasmine, lemon and other plants can kill protobacteria, such as diphtheria and dysentery bacteria, within 5 minutes. The fragrance of jasmine, rose, carnation, lily of the valley, violet, rose, osmanthus and other plants has obvious inhibitory effect on the growth and reproduction of mycobacterium tuberculosis, pneumococcus and staphylococcus. Hupilan, Huweilan, tequila, palm, dwarf kale, striped kale, Sedum, and cultivated pineapple can purify the air at night. If you put two pots of this plant, such as pineapple, in a room of 10 square meter, you can absorb all the carbon dioxide discharged by a person at night. Cactus, lotus, fairy finger, ruler and epiphyllum can increase negative ions. Turn on the TV or computer indoors, and the negative oxygen ions will decrease rapidly. The stomata on the fleshy stems of these plants are closed during the day and opened at night, which absorbs carbon dioxide and releases oxygen at the same time, increasing the concentration of negative ions in indoor air. Orchids, osmanthus fragrans, wintersweet, cauliflower taro and osmanthus fragrans can absorb suspended particles and smoke in the air. Lilac, jasmine, rose, violet, chrysanthemum, mint, these plants can relax people and help them sleep.

In addition, plants that are too bright and harsh, have peculiar smell or are too fragrant should not be placed indoors. Such as oleander, oleander and Datura flower. These flowers and plants are poisonous and harmful to human health. The fragrance of cordate telosma has a strong stimulating effect on people's sense of smell, and it will also discharge a lot of waste gas at night, which is not good for people. Evergreen stems and leaves contain dumb enzymes and calcium oxalate, which will cause strange itching when touching the skin, and poisoning when eaten by mistake. Other plants, such as tulips, contain poisonous alkali; Mimosa, frequent contact will cause hair loss; Narcissus, contact with leaves and flower juice, can cause skin redness and swelling.
