The ideal is to always use rainwater, free of disinfectants such as chlorine and not too calcareous.

Infusion dose

To make the decoction use approx. 50 grams of fresh tansy per 100 ml of water . If you use dried tansy instead, 5 grams of the plant will suffice. The infusion thus obtained will be then diluted in water in proportions of 1 to 10. Then, after dilution, we will have one liter of infusion for 50 grams of fresh tansy (or every 5 grams of dried plant).
