A nettle bath tends to work a bit faster than other herbs if you are dealing with more aggressive situations.
Make a strong infusion of nettle tea by boiling it until the water is tinted, then strain into a pitcher of water with a handful of sea salt and a 1/2 teaspoon of turmeric powder. Sit in an 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.
