Wormwood has perhaps gained the most interest for one of its active ingredients, absinthol, used in the alcoholic spirit “absinthe”. However, this potent herb has a long history of use stretching back to Ancient Greece and the time of Hippocrates. It's classed as a bitter herb that is used for digestive health and to expel worms - hence the name - and is anti-parasitic, anti-inflammatory and hepatoprotective.
