I liked to pick my nose when I was a child, and then I often had nosebleeds. My elders said to me, "If you hold your head up when you have a nosebleed, it will stop faster."

When I was a child, I believed what my elders said. Every time I have a nosebleed, I lean my head back. Although the nosebleed did not flow out, it formed the illusion that the bleeding was not serious. In fact, the blood flowed into the throat with the nasal cavity. When I was young, I drank a lot of my own blood because of this method ...

Later, when I grew up, I went to the hospital for consultation. It is very wrong to look up to stop bleeding. The nosebleed will flow into my throat and even into my lungs, which is even more dangerous!

2. The fishbone is stuck in the throat

I believe many people have had the experience of accidentally eating fish and getting the fishbone stuck in their throat.

My mother will let me swallow a rice ball first and bring the thorn into my stomach through the pressure of the rice ball on the thorn. The rice ball can't hold the fishbone, so let me drink some vinegar, thinking that vinegar will soften the fishbone, so I can soften it and swallow it. This is also without scientific basis!

Swallowing rice balls may cause fishbones to sink into the meat, which is deeper and more difficult to take out! Although the rice ball can occasionally bring the thorn down from the throat, it may prick the food passage again, causing esophageal bleeding, or puncture the trachea to cause infection and life-threatening.

Besides, drinking vinegar is not good. Vinegar stays in the esophagus for too short a time, which can not achieve the purpose of softening fishbone at all, but will lead to gastric acid corrosion and physical discomfort.

3. lick the rotten mouth with a spatula

When I was a child, I often rotted my mouth, which was a small area of oral ulceration. It hurts badly when you lick it with your tongue, and it will get worse and worse.

My grandmother asked my mother to use the iron kitchen knife at home, with a little rust, and put it by the pot to smoke. Steam condensed into water on the rusty kitchen knife and applied it to my mouth, saying that the wound would heal faster.

Anyone who knows a little about science knows that this method has no scientific basis for treatment and is extremely dangerous! Rust contains tetanus bacillus. If you enter the skin through an ulcer wound, you may get tetanus!
