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.
