As for this "arsenic", it is because in ancient Chinese historical documents, unprocessed stones containing arsenic trioxide are called arsenic. After refining, it is arsenic. The word "ba" comes from "ba". Legend has it that it is a fierce beast that eats people.
Said this arsenic, is famous in history, Wu Dalang is the most popular one. It was killed by adulterers Ximen Qing and Pan Jinlian with this poison. Then Song Wu avenged his brother, killed the tea woman, sister-in-law and Ximen Qing, and then went to Liangshan.
Whether the story is true or romantic, we can only say that when Shi Naian wrote Water Margin, we knew that arsenic was a poison.
If the ancients knew arsenic, it had no national boundaries. In 1 century, the Greek doctor diogenes described arsenic trioxide produced by roasting arsenic sulfide, which was used in medicine. I don't know if the people he treated survived.
An alchemist in ancient China accidentally got this thing out when he was refining the elixir. Is it true that everyone who ate the elixir died of poisoning? If you are interested, you can check it.

It is said that there should be many historical celebrities who died of arsenic trioxide, but it is impossible to verify them one by one. I also heard it through hearsay,
Like Guangxu, it is said that the cause of death was that Lafayette Cixi poisoned the snacks mixed with arsenic. And Li Tuo, the last emperor of North Korea, said that he was also poisoned by the Japanese with arsenic. The truth of these two events has been covered up in historical occasions. However, it is said that Napoleon died of chronic arsenic poisoning, which is also supported by laboratory reports.
Speaking of it, ancient people were able to draw a conclusion whether something was poisonous or not, and there were no microscopes and chemical reagents, because the level of science and technology was there. In this way, we can draw the conclusion that arsenic is toxic, isn't it the experience accumulated with human life? We don't know how many unknown people died of arsenic in this history.
