Herbal Baths

Baths are often used in herb magic, for they are an easy way to spread an herb’s power over the entire body.
There are two methods; one, make a sachet (use about one-half to one cup of the appropriate enchanted herb) of cheesecloth. Drop this into the warm bath water.
A better method entails the preparation of an infusion.

Add the strained liquid to the tub.
Essential oils are also sometimes added to baths.

Just a few drops are all that is necessary for most oils; too much may irritate the skin
