Its main components can includecamphor,cineole, α- and β-thujone, artemisia ketone (CAS: 546-49-6),borneoland bornyl acetate as well as a wide variety of otherphenols,terpenes, and aliphatic compounds.The presence and concentration of thujone varies largely by species, as well as the climactic, and soil conditions where the plant is grown.
All parts of the plant containessential oilswith all-purpose insecticidal properties (especially in the killing of insectlarvae).This is best used in a weakinfusion, but use on garden plants is not recommended, as it also reduces plant growth.

Mugwort pollen is one of the main sources ofhay feverand allergicasthmain North Europe, North America, and parts of Asia.Mugwort pollen generally travels less than 2,000 meters.The highest concentration of mugwort pollen is generally found between 9 and 11 am. The Finnish allergy association recommends tearing as a method of eradicating mugwort.Tearing mugwort is known to lessen the effect of the allergy, since the pollen flies only a short distance.Cut flowers before they bloom to avoid allergens and reproduction of the plant.
Mugwort often contains theneurotoxincompoundthujone, though this varies greatly by species and the environmental conditions where the plant is grown.Toxicity to humans is believed to be weak, though some studies have linked high concentrations of thujone to seizures and an abortive effect.The Botanical Safety Handbook suggests the Mugwort not be used during pregnancy unless it is under the supervision of a medical expert.In rare cases, minor allergic skin reactions have been recorded in relation to moxibustion, or the burning of dried Mugwort.
