Artemisia absinthium, commonly known as Wormwood, is a plant usually found in the barren soils of the Mediterranean region and temperate Europe. It is an annual or perennial herb in the genus Artemisia and belongs to the family Asteraceae (daisy family). The colour of the leaves is silvery-green, finely hairy and fragmented; the stem is straight and usually reaches 60-120 cm in height. The flowers are small, yellow and usually bloom in late summer. The plant has a distinct aroma, which makes it valuable for medicinal and culinary applications.
Wormwood contains bitter components such as absintin and anabsintin. These components are particularly known for their stimulating effects on the digestive system. However, consumption in high quantities can pose a risk to health, especially due to the substance thujone. Wormwood has been used throughout history in both traditional medicines and alcoholic beverages (e.g. absinthe) and continues to be used today in many herbal supplements and aromatic products.
