11. The anthelmintic activity has been claimed to be due to flavaspidic acid, a phloroglucinol derivative. 12. A study was conducted on free-range Florida panthers on the effectiveness of anthelmintic treatment. 13. The species also shows anti-fertility, styptic, anthelmintic and anti-tubercular properties. 14. The drug frequently kills both roundworm and tapeworm, especially the former, and is therefore an anthelmintic . 15. The female flowers of hagenia contain anthelmintic , which is used to treat tapeworms among the local populations. 16.

High-quality feed blocks may also be treated with anthelmintic medicines for treatment against parasites in animals. 18. Subsequent to this, the anthelmintic activity was isolated and identified as a family of closely related compounds. 19. He was responsible for the discovery in the late 1930s of phenothiazine, a safe and effective anthelmintic . 20. Pills containing anthelmintics are used in mass deworming campaigns of school-aged children in many developing countries.
