2 parts pennyroyal 1 part thyme 1 part wormwood

Herbs may be cut or whole; construct a pillow for your pet to sleep on and then stuff it
with the pennyroyal, thyme, wormwood. This makes a nice gift for those favorite
dogs in your life. These herbs help to repel fleas naturally and without harsh chemicals.
