Tansies are mainly perennial herbs, ones you plant them and the next years you will treat them as weeds.
I planted mine a year ago, in front of the garden
(my mistake), yes, it is invasive, but beautiful and very good for bees.
And yes, it smells! "Shoo-Fly"! More than 6 feet, very strong, health plant, no matter how much I pruned it.
I am going to
make a strong anti-parasitic tea, also using wormwood, black walnut hulls,
and cloves.
I have enough to make a tincture too. It can be used while fasting to expel worms, especially round
and thread. It is also valuable for treating hysteria and kidney
weakness. It has also been used to promote menstruation. Tansy has
shown to be helpful in treating gout and epilepsy. It has been
thought to relieve the pain of sprains, bruises, blemishes,
scabies, and pain of rheumatic joints. Tansy is very effective
for relieving the pain and inflammation associated with arthritis.
I have arthritis problem so I will try this tincture this fall.
Remember, tansy is a very strong herb and may be poisons.
