'''Vernonia oil''' is extracted from the seeds of the ''[[Vernonia galamensis]]'' (or ironweed), a plant native to eastern [[Africa]].

:''Vernonia seed contains about 40 to 42% oil of which 73 to 80% is [[vernolic acid]]. This is about 30% more vernolic acid than the best varieties of [[Venonia anthelmintica|V. anthelmintica]]. Products that can be made from vernonia include epoxies for manufacturing [[adhesive]]s, [[varnish]]es and [[paint]]s, and industrial coatings. The low [[viscosity]] of vernonia oil would allow it to be used as a nonvolatile [[solvent]] in [[oil-based paint]]s since it will become incorporated in the dry paint rather than evaporating into the air.''<ref>{{cite book
