Video : Ascaris removed during surgery

"In general, when Ascaris feel threatened they group together in their colonies to ball up causing blockages or intestinal obstructions. I spoke to a surgeon who use to do many surgeries in India with people who had ascaris. He told me that they would find balls of Ascaris along the intestinal tract. How they removed them was to pull the intestines out and run their hands on the outside of the intestines to squeezing them out. Afterwards, a person was given a heavy dose of anthelmintics."

IIRC, betel nut (areca catechu/bing lang) is a neurotoxin to roundworms. With the proper dosage, it paralyzes them temporarily. Tweet
