We are not allowed to eat green onions. Is this rule effective?

"Red umbrellas, white poles, let's lie on the board together after eating..." Do you still remember this "divine song" that was popular in the streets and alleys? The wild mushrooms in Yunnan once became a hot search because of this song. In a blink of an eye, it's time to eat mushrooms again.

However, just recently, the Kunming Institute of Botany, Chinese Academy of Sciences and the Yunnan Key Laboratory of Fungal Diversity and Green Development jointly released the "2022 Edition of Common Toxic Fungi (Poisonous Mushrooms) in Yunnan", in which the famous wild mushroom Jianshouqing (red onion) was included in the list of not picking, not purchasing, not processing, and not eating. As soon as this list came out, it once again attracted the attention and heated discussion of many netizens. Let's talk about it today.

01. Wild mushroom poisoning in Yunnan

It is hard to say whether this guidance is effective or not because there is a contradiction. Please take a look at the data and you will get the idea to some extent.

From 2004 to 2010, the proportion of poisoning cases in Yunnan Province was basically 1:1:1, with the number of people poisoned in collective canteens, catering service units, and rural areas and families. But what about the number of deaths? All of them were concentrated in rural areas and families.

This is a rather embarrassing fact.

Generally, those who pick, trade and consume mushrooms are mainly urban groups, and their consumption pattern is also collective canteens, catering service units, etc. These places, on the one hand, have relatively rich experience in mushroom identification and standardized operations, and they also often have convenient medical services. Therefore, they basically will not encounter any problems, and even if they do, treatment is also very convenient.

But on the other hand, for rural areas and families who like to pick mushrooms themselves, they rely more on personal experience. In addition, the location is remote and the roads are long, and medical care is not convenient, which makes treatment more troublesome.

Therefore, how much impact this list will have remains to be seen.

02. Causes of mushroom food poisoning in Yunnan Province

Let’s talk about this soul-delicacy that is known as the favorite of Yunnan people. It really goes straight to the soul if you are not careful.

For example, in the statistics of mushroom food poisoning causes in Yunnan Province from 1985 to 2000,

We can see that porcini mushrooms are a very significant type of poisoning factor (of course, the more important reason is that some brave people try mushrooms that no one knows about).

Wang Zengqi once said: "The most abundant and cheapest is porcini. When porcini are in season, every restaurant sells fried porcini, and even the canteen of Southwest Associated University has a bowl of it on the table. Porcini is the color of beef liver, smooth, tender, fresh, fragrant and delicious. When frying porcini, you need to put more garlic, otherwise it will easily make people faint."

This shows how popular mushrooms like porcini are.

What about the green-green mushroom? It happens to belong to the Boletus family. The green-green mushroom is mostly from the Boletaceae family. It is also called the green-green mushroom because it turns indigo blue after being injured, so it is called the green-green mushroom, which sounds a bit like the red-crowned crane.

Well, this is a problem. The boletus to which the scutellaria belongs has such a large market, and the scutellaria is poisonous, so there are many causes of death.

03. Why is the green hand poisonous?

The taste of Jianshouqing is actually very good, but the prerequisite is that it is well processed.

As a kind of fungus, their basic characteristics must include an important physiological process: spores.

This thing is not simple.

Spores are easily blown away, such as when shaking or moving, and the structure of spores has strong resistance to adversity.

The result is that if some spores are not processed during processing, they can become pathogenic factors.

04. What are the reactions to green hand poisoning?

The symptoms of green hand poisoning are generally as follows.

1. Gastrointestinal inflammation. Poisoning with green licorice can cause symptoms such as nausea, vomiting, abdominal pain and diarrhea. If not treated in time, dehydration is likely to occur, leading to electrolyte imbalance in the human body, which is troublesome.

This type is often caused by Huang Jianshou.

2. Mental symptoms. This type of symptom is what we often call the "little man" problem.

Poisoning by the green hand can easily lead to mental abnormalities. Some people will have hallucinations, in which case they will have all kinds of absurd behaviors, and some people will even commit suicide or murder. This type of situation is often caused by the red hand.

Well, let’s end here. So, does this rule work?
