Small threadworm, common roundworm and tapeworm

For small threadworm (pinworms), J.F. Oberlin recommended eating raw or cooked carrots.
For common roundworm, he used the stem and blossoms of feverfew, called the worm herb. Sébastien Scheidecker also used an infusion of elderberry mixed with sulphur and cinchona.
For rare cases of tapeworm, he used buckbean, also effective against all types of worms.
