Mugwort (Artemisia vulgaris), also know as Felon herb, Common Wormwood, Common Mugwort, Douglas Mugwort, St. John's Plant, Sailor's Tobacco, Cronewort. It is native to temperate Europe, Asia, northern Africa and Alaska and is naturalized in North America, where some consider it an invasive weed. The leaves and buds, best picked shortly before the plant flowers in July to September, are used as a bitter flavoring agent to season fat, meat and fish. North Vietnameses like to make scambled eggs with chopped mugwort leaves (Vietnamese name: ngai cuu).
