1. Pregnancy and Breastfeeding:
Mugwort: Mugwort is known to be an emmenagogue, which means it can stimulate menstruation. It may cause uterine contractions, making it unsafe for pregnant women. It’s also not recommended during breastfeeding.
Clary Sage: Clary sage can also stimulate uterine contractions, making it potentially unsafe during pregnancy.
2. Epilepsy and Seizure Disorders:
Mugwort: Mugwort contains thujone, which can be neurotoxic in high doses and may trigger seizures in susceptible individuals.
Clary Sage: While generally safe, clary sage can also potentially affect the nervous system, so caution is advised for those with a history of seizures.
3. Hormonal Imbalances:
Clary Sage: Clary sage has phytoestrogenic properties and can influence hormone levels. It may be contraindicated for individuals with hormone-sensitive conditions like certain types of cancers (e.g., breast, ovarian, uterine).
4. Allergies and Skin Sensitivity:
Blue Tansy: Although it’s generally considered safe and soothing, some individuals may experience allergic reactions or skin sensitivity to blue tansy.
Mugwort: Mugwort can cause allergic reactions, particularly in individuals allergic to plants in the Asteraceae family (e.g., ragweed, chrysanthemums).
5. High Blood Pressure:
Clary Sage: Clary sage may have a mild hypotensive effect, potentially lowering blood pressure. Those with low blood pressure or on blood pressure medications should use it cautiously.
6. Children and Pets:
Essential oils can be potent and should be used cautiously around children and pets. Mugwort, in particular, should be avoided around children due to its thujone content.
