Tansies

Tanacetum, commonly known as tansy, is a plant traditionally associated with European and North American herbal medicine practices. While it has been used in various folk remedies for conditions such as parasites, inflammation, and menstrual disorders, no specific traditional uses are recorded for the genus Tanacetum itself. Scientific evidence suggests that T. vulgare can exhibit species-specific responses under certain environmental stresses, such as increased abscisic acid production and reduced biomass when facing combined drought and herbivory stress. Additionally, both T. vulgare and Solidago gigantea have shown strategies to reduce metal uptake in contaminated soils, with S. gigantea demonstrating lower metal accumulation levels across its organs. The essential oil of T. vulgare has been noted for improving memory and increasing BDNF expression in the hippocampus without causing pathological changes, while multiple plant species within the Asteraceae family have been identified as sources of sesquiterpene γ-lactones with potential biological activity. No major safety issues or recorded drug interactions are associated with Tanacetum.
