What are the three types of flowers suitable for keeping indoors during pregnancy

For pregnant women, the three major types of flowers most suitable for placing indoors are:

1. Plants that can absorb toxic chemical substances

Aloe, spider plant, snake plant, one-leaf plant (Aspidistra), and split-leaf philodendron are natural scavengers that can remove harmful substances from the air. English ivy, sago palm, chrysanthemum, kumquat, pomegranate, purslane, Chinese rose, camellia, pomegranate, orchid tree (Aglaia), daisy, wintersweet, and marigold can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, and nitrogen peroxide. Orchids, osmanthus, wintersweet, caladium, and red-back mangrove (Excoecaria) are natural dust removers; their cilia can intercept and absorb floating particles and smoke dust in the air.

2. Plants that can kill bacteria

The volatile oils produced by fragrant flowers such as roses, osmanthus, stock (Matthiola), jasmine, lemon, rose (Rosa multiflora), dianthus, lily of the valley, and crape myrtle have significant bactericidal effects. Plants such as crape myrtle, jasmine, and lemon can kill native bacteria such as diphtheria bacteria and dysentery bacteria within 5 minutes. The fragrance given off by plants such as Rosa multiflora, dianthus, lily of the valley, stock, roses, and osmanthus has a clear inhibitory effect on the growth and reproduction of tubercle bacilli, pneumococci, and staphylococci. Succulent plants native to tropical arid regions, such as cacti, have stomata on their fleshy stems that close during the day and open at night; while absorbing carbon dioxide, they produce oxygen, increasing the concentration of negative ions in indoor air. Plants such as snake plant, Sansevieria, agave, as well as Opuntia, Kalanchoe, sedum, Bryophyllum, and cultivated bromeliads can also purify the air at night. Plants such as lilac, jasmine, rose, stock, and mint can help people relax, feel cheerful, aid sleep, and also improve work efficiency.

3. Plants that can repel mosquitoes and insects

Mosquito-repelling scented geranium. It is an aromatic plant of the geranium family whose genetic structure has been modified, and it was only introduced from Australia in recent years. This plant is drought-tolerant, can grow to maturity within half a year, and with proper care can survive for 10 to 15 years; its branches and leaves can be shaped at will, giving it high ornamental value. Mosquito-repelling scented geranium gives off a fresh, elegant lemon fragrance, has a very good mosquito-repelling effect indoors, and has no toxic side effects on the human body. The higher the temperature, the more fragrance it releases and the better its mosquito-repelling effect. According to tests, one pot of mosquito-repelling scented geranium with a crown spread of more than 30 cm can drive mosquitoes and insects out of a room with an area of more than 10 sq m. In addition, a plant called pyrethrum contains pyrethrin and can also effectively repel mosquitoes and insects.
