Anthelmintic

Research is progressing well on finding native plants with anthelmintic properties.

The parasites thrive in an environment of dirt, and the main lines of precaution are those dictated by sanitary science. Malefern, santonine, thymol and other anthelmintic remedies are prescribed.

However, the lighter boiling constituents of tne oil are much less irritating and at the same time they are apparently more anthelmintic than the heavier fraction.

Our experiments indicate that this constituent is anthelmintic and also a gastrointestinal irritant, while the lighter portion of the oil is apparently even more anthelmintic and much less irritating.

The bark of the root is likewise valued as an anthelmintic in cases of tape-worm.

Rather than give a long list of the anthelmintics available, I will describe the helminths that cause problems and then suggest methods of control.
