Today I have decided to choose another of the poisonous plants, Tansy (Tanacetum vulgare) with a beautiful nickname “golden buttons”, which is exactly how the flowers look like.
Because the plant blooms for a long period of time and the gold-yellow flowers are firm and durable, Tansy easily attracts attention. Therefore it’s important to know that the entire plant, especially the flowers, is poisonous. A small dose can help to remove intestinal parasites, but because the toxin content may vary from one plant to another, it’s safer to use other herbs for this purpose.
The main poison is thujone, which is a terpene, acting as a neurotoxin. The same thujone is present in wormwood and it’s why absinth (herbal liqueur made from wormwood, anise and fennel) has been forbidden in many countries. And that’s why absinth is still so attractive. The story about forbidden fruit is one of the best ads.
Thujone content in leaves is comparable to wormwood, but in flowers it’s roughly three times larger. So if you insist on Tansy experiment, start with the leaves and be careful.
Thujone is also a substance that causes increased blood flow through internal organs, especially in the abdomen and the pelvis area. Therefore, pregnant women should avoid it for sure! The effect of thujone is so strong, that Tansy flowers have been earlier used as a medicine leading to abortion.
Thujone has a strong menthol odor and together with other camphor-like terpenes in Tansy causes significant repellent effects. Try to put a dried bouquet into the wardrobe and see how the clothing moths fly away in disgust.
Did you know that because of the strong repellent effects Tansy has been used in funeral houses? In some countries, they put bouquet into the coffins to keep the bugs away as long as possible.
Anyway, I would like to finish my post in positive. Despite all warnings about poisonous thujone, there is one major healing application. Homemade ointment from Tansy flowers can relieve rheumatic pains.
With love, Ivana
