From "fango", Italian word for mud - Rich in natural minerals, the mud is used in baths or heat packs to increase circulation, absorb excess oils, tighten pores, soften the skin, relieve and relax muscles and aid in the healing of stressed joints.

Mud used in spa treatments is different from plain old dirt. Most spas use a clay base and add natural ingredients such as algae, kelp, herbs, minerals, peat moss, paraffin or essential oils. These additives help increase the mineral content and add their own beneficial effects to the mud treatment.
