Used primarily as a natural insecticide due to its strong antifeedant and growth-disrupting properties against a variety of insect pests. It is effective in controlling aphids, mites, and other soft-bodied insects in agriculture, especially in organic farming where synthetic pesticides are avoided. Also investigated for its potential in pharmaceutical applications, including anti-inflammatory, antimalarial, and anticancer activities, due to its ability to interfere with cellular processes in disease models. Its bitter taste also makes it useful in research related to taste perception and as a denatonium additive to prevent ingestion of harmful substances.
