Make a strong infusion of agrimony bath by boiling 1/8 cup of dry leaves with 1/8 cup of another dry plant until the water is tinted, then strain into a pitcher of water with a 1/16 cup of sea salt. Allow to cool to lukewarm temp and pour into a bowl/basin. Take a shower and then stand or sit in the empty bath, and pour the lukewarm mixture over your head. Do not wash the mixture off, allow your skin to air dry. Praying beforehand helps to set the intention for the bath.
