Currently, tansy is less commonly used in medicine. It should be noted that despite the valuable properties of this plant, many side effects can occur. Excessive use can lead to liver and kidney damage. It can be dangerous for people allergic to plants in the aster family, as well as for pregnant women, as tansy has abortifacient properties.
However, as mentioned earlier, tansy has found a variety of applications in the garden and household.
With this plant, we can combat pests such as Colorado potato beetles, flies, aphids, ants, mosquitoes, ticks, or moths. Preparations from tansy can be used in spring to spray trees and shrubs and destroy overwintering pests such as spider mites and aphid eggs.
The use of remedies from this plant can also reduce the occurrence of plant diseases such as powdery mildew and rust. A bouquet of tansy leaves is a good way to keep flies and wasps away. Bunching this plant in gauze can be hung between garments to keep moths away. Essential oil can be made from tansy flowers, which effectively repels insects, especially mosquitoes and ticks.
When looking for suitable personal protection against insects, such as when walking in the woods, it is advisable to rub tansy petals on the skin. Placing some plants on the balcony will effectively deter insects and make it difficult for them to enter the apartment.
