Essential oil of Wormwood is steam distilled from Artmesia Absinthium leaves, twigs and flowering tops.

Blending: Wormwood Essential Oil blends well with the essential oils of jasmine, lavender, oak moss and orange. Few Words of Caution (this is not an exhaustive list of possible side effects. Consult your physician/therapist for guidance about using this oil): Keep away from children. External use only. Do not take internally due to potentially toxic/poisonous effects of chemical thujone in Wormwood. In the United States, the Food and Drug Administration (FDA) restricts any commercial product containing thujone to 10 parts per million (ppm) or less. This amount is considered negligible and thus safe for most populations. Wormwood oil is sold here only for diluting with other products to produce safe concentration. Wormwood essential oil should never be directly applied to the skin, as its compounds are too concentrated and can result in painful burns. For topical application dilute Wormwood essential oil with carrier oil or other cosmetic base to produce safe concentration. Pregnant Women or those who are breastfeeding and children should not use this oil. Thujone stimulates the brain and has been known to cause seizures. Wormwood may also decrease the effectiveness of common anti-seizure medications, such as gabapentin and primidone. Using Wormwood oil with the heart disease medication warfarin may cause intestinal bleeding. Wormwood is toxic to the kidneys and may increase your risk of kidney failure. If you’re allergic to members of the Asteraceae family, such as ragweed and marigolds, you may also react to wormwood, which is in the same botanical family.
