This is an herbal blend that relaxes the body and mind. Just drop the bag into hot water (attach it under the faucet and let the water run through) in your bath, then adjust the water temp to your level, fill the tub, drop the bag in and soak in all the goodness. The bag is muslin and is reusable, so you can just reorder the blend and put it in the bag. This can also be drank as a tea.
