Discussion

Artemisia absinthium provides the flavoring as well as the psychoactive ingredient for absinthe liquor, a beverage that is illegal in some markets. Known as a powerful neurotoxin, absinthe in large quantities is addictive as well as deadly. The species is popular in the horticultural trade. Prized by gardeners for its gracefully scalloped leaves and gray-green foliage, it creates an attractive and winter-hardy flower border.
