Song Dynasty period, the ancients suffered from parasites how to treat?

In our modern society everyone will find that in fact, uh, because maybe in the case of eating food is not very clean, the body may appear inside the parasite, then now we can go ahead to preventive medicine, or eat some of the worming medicine, but in ancient times is how to take out the parasites?

First of all, there is a book called "Class Case of Famous Doctors", which records that. There is a man he changed a disease, eat anything to vomit on the body very much when let him eat a pill, ate that pill 20 days later, the man pulled out a few pieces of meat like a toad as well as white pus after his disease is cured. There is another person who ate it and vomited, and his eyes were blind, and his ears were deaf, and he pulled out five or seven green snakes and a lot of evil pus after he ate the pill, and then he was also well.

"Sun's medical case" above recorded that there is a person at first is the whole she for the phlegm, and then after taking the medicine it is still not good, but also the pain is even more powerful, and then changed the medicine, to the night this person began to dilute. He was a little nauseous. Then someone said that the man had passed away and there was no need to go back to the doctor, but the doctor thought that he must not have passed away, he might have passed out from the pain, and when he went in, he found that the man had really just passed out from the pain. So he gave him ginger soup. At this time she woke up and told her servant that her stomach was in pain and that she had pulled up something. In the look was actually a red loach.

These books are real examples. So that our ancient Chinese medicine can also fight down the soldiers, but still need to meet some medical skillful doctors.
