A while ago, a netizen in Zhengzhou took a photo with an oleander in his mouth and entered the hospital the next day.
This is really poking the old nest of the "Zhen Scholars". Netizens have said that You have to listen to An Lingrong's words, and she told everyone in the play that oleander cannot be eaten.
Perhaps because it is so common, many people take it for granted that oleander is not poisonous, and poisoning incidents are not uncommon. In fact, oleander is so toxic that some people have even used it to commit suicide in India. Moreover, there are still many poisonous plants around us - some of them are less toxic, and they will have diarrhea when they eat them; Some are very toxic, and if you eat them, you will not be able to see the sun of tomorrow; Some don't eat it; Some smells are not good for health...
Zhou Zhijun consulted Wu Zhixing, a famous garden expert, the former director of the science popularization room of Shanghai Botanical Garden, and "Dr. Flower", and combined the contents of flora and the Royal Horticultural Society of the United Kingdom, he brought such a "guide to pulling weeds" (with a list of poisonous plants at the end of the article).
