In addition, peony, rose, Narcissus, lily, orchid and other famous flowers are also fragrant. However, people will feel chest tightness, discomfort, poor breathing and may lose sleep when they are exposed to this strong fragrance for a long time.

Thorny flowers and plants

Although cactus has a good air purifying effect, its surface is covered with thorns that may inadvertently hurt people. If there is an elderly person or an ignorant child in the family who has difficulty in moving, it is necessary to pay attention to its placement when raising cactus.

In addition, Bayberry and other plants also have sharp thorns, and the stems and leaves contain toxins. Therefore, breeding should also be cautious.

Of course, here are just some suggestions, not to let everyone throw away all these plants in the house. For example, too fragrant flowers are not suitable to be kept indoors, but it is still good to keep them on the terrace, garden and ventilated balcony.

As for what plants to raise, it is suggested that you can raise some plants such as mint, lemongrass, Chlorophytum comosum, dracaena lucky bamboo plants and sansevieria / snake plants at home. The volatile substances are not only harmless, but also can purify the air.
