Verbena is a more or less
hairy herb, growing up to 90 centimeters in height, erect, but decumbent at the
base. Leaves are 5 to 10 centimeters long, variously lobed and narrowed to the
base; the lower ones are stalked, pinnatifid or coarsely toothed, more
or less hairy, and usually hoary on the nerves beneath; this upper ones
are without stalks and 3-lobed. Flowers are small, 4 to 6 millimeters long, without stalks and borne on
dense, bracteate heads which elongate as the fruit ripens. The calyx
is twice as long as the bracts and half as long as the corolla tube,
minutely 5-toothed, and glandular- hairy. The corolla is blue or lilac,
and hairy, with spreading limb; the lobes are subquadrate, with a hairy
throat. Fruit is dry, ultimately spreading into four 1-seeded nutlets
which are oblong and dorsally smooth, their under faces covered with
minute, white flaking cells.

Study isolated ß-sitosterol, ursolic acid, oleanolic acid, 3-epiursolic
acid, 3-epioleanolic acid and showed the ether, chloroform and methanol
extracts of VO to have antiinflammatory activity. (3)
Study of aqueous extracts of V officinialis showed novel neuroprotective
effects supporting its folkloric use and a potential as a neuroprotective
agent against neuronal loss in Alzheimer's Disease. (2)
• Gastroprotective / Antioxidant
/ Antiinflammatory: Study showed extracts to exhibit
antiinflammatory activity and reduction of gastric damage. It also showed
improved wound healing suggesting the presence of some lipophilic active
• Volatile Constituents:
