Why "don't pick wild flowers on the roadside"

When traveling in spring, you must prevent pollen poisoning. Studies by pharmacists and florists in China have found that more than 50 kinds of common flowers contain toxic substances, and improper human contact can easily lead to some diseases. For example: 1. Evergreen has high ornamental value, but it can cause itchy skin. Its leaves are green first and then red, but they are poisonous, especially the fruits. 2。 Nerium oleander can cause cancer.

This kind of flower is very bright and easy to cultivate. However, its leaves, skins, flowers and fruits all contain a highly toxic substance called bamboo peach fungus, which can easily induce cancer of respiratory tract and digestive system if exposed to too much.

3。 The reason why mimosa is "ashamed" when touched is because it contains a mimosa, which is a highly toxic organic substance. Too much contact with the human body will make people lose their hair or cause general discomfort.

4。 Narcissus should not be eaten by mistake. Although daffodils have high medicinal and ornamental value, their flowers contain a toxic substance called "Lacodine", which can cause vomiting, diarrhea and other symptoms if people and animals eat them by mistake. In addition, calla lily, winter coral, tortoise shell bamboo, poinsettia, Lycoris radiata and lily all contain different toxic substances. Therefore, in Shang Huashi, we must understand the characteristics and toxic side effects of flowers, and do not touch them at will to prevent toxins from entering.

A few people with allergic constitution are very sensitive to the smell of some flowers (such as roses), which leads to allergic reaction, which is also a problem that tourists should pay attention to. If you are poisoned or feel unwell, you should go to the hospital immediately.
