The Palaearctic species of the Gasteruption assectator aggregate (Hymenoptera, Gasteruptiidae) are revised and three species are recognised. Two species are re-instated: Gasteruption boreale (Thomson, 1883), stat. n. and Gasteruption nigritarse (Thomson, 1883), stat. n., and both are excluded from the synonymy with Gasteruption assectator (Linnaeus, 1758). The general distribution of both speci...

Medicinal plants have been widely employed in treating various diseases for centuries and are still a major resource and repository that can be further exploited for a variety of infectious and non-infectious ailments. The popularity of medicinal herbs has grown significantly in recent years despite a dearth of information regarding their modes of action and continuing concerns over their effic...

The lipophilic ̄avonoids in leaf and ̄ower of Tanacetum parthenium and T. vulgaris have been compared. While those of T. parthenium are methyl ethers of the ̄avonols 6-hydroxykaempferol and quercetagetin, the surface ̄avonoids of T. vulgare are methyl ethers of the ̄avones scutellarein and 6-hydroxyluteolin. Apigenin and two ̄avone glucuronides are surprisingly present in glandular trichomes on...

Oral administration of the feverfew (Tanacetum parthenium) extract led to significant antinociceptive and anti-inflammatory effects against acetic acid-induced writhing in mice and carrageenan-induced paw edema in rats, respectively. These responses were dose-dependent (10, 20, 40 mg/kg, p.o.). Parthenolide (1, 2 mg/kg i.p.), the active constituent of the extract also produced antinociceptive a...

Schistosomiasis, a parasitic disease caused by trematode flatworms of the genus Schistosoma, affects more than 200 million people worldwide, and its control is dependent on a single drug, praziquantel. Tanacetum vulgare (Asteraceae) is used in folk medicine as a vermifuge. This study aimed to investigate the in vitro schistosomicidal activity of the crude extract (TV) and the essential oil (TV-...
