Description

Mugwort (Artemisia vulgaris) is a perennial herbaceous plant belonging to the Asteraceae family. It is commonly found in temperate regions across Europe, Asia, and North America, thriving in waste areas, roadsides, and fields. The plant can grow between 1.5 to 8 feet tall, featuring gray-green, elliptical leaves that are often lobed at the tips. Mugwort is known for its aromatic properties and has been used traditionally in herbal medicine.
