About
Artemisia herba-alba, the white wormwood, is a perennial shrub in the genus Artemisia that grows commonly on the dry steppes of the Mediterranean regions in Northern Africa (Saharan Maghreb), Western Asia (Arabian Peninsula) and Southwestern Europe. It is used as an antiseptic and antispasmodic in herbal medicine.
Safety
Essential oil of A. herba-alba, from the Sinai Desert, contains mainly 1,8-cineole and appreciable amounts of α- / β-thujone as well as other oxygenated monoterpenes including terpinen-4-ol, camphor and borneol. Davanone, chrysanthenone and cis-chrysanthenol have been described as major constituents in some populations of A. herba-alba from Morocco and Spain. Less common non-head-to-tail monoterpene alcohols have been identified in some populations from Negev desert, such as santolina alcohol and yomogi alcohol.
Several sesquiterpene lactones were found in the aerial parts of A. herba-alba. Mainly, eudesmanolides and germacranolides types were reported in most cases. A variety of flavonoids were also described mainly with methylated (i.e. patuletin) and O-methylated (i.e. hispidulin, cirsilineol) aglycones. The presence of C-glycosides (i.e. isovitexin, schaftoside, isoschaftoside) is also noticeable.
Uses
Artemisia herba-alba is good fodder for grazing animals, mainly sheep, and in the Algerian steppes cattle.
