This is the plant that is used for making traditional bitters, also an ingredient in absinthe in much larger quantities, and also used in herbal medicine as an effective vermifuge (expels parasites). Of course, high dosage or extended use is very toxic due to a buildup of thujone in the system. It has an anise flavor to it. It is used for various digestion problems such as loss of appetite, upset stomach, gall bladder disease, and intestinal spasms. But only sparingly. It is called Wormwood due to the fact that it will in fact kill parasites, and is now showing success in the fight against some cancers.
