Mud is supposed to cure everything from psoriasis to acne. Mud certainly is all the rage these days. I'm sure they feel good when you put them on, and I imagine the results are in the eye of the beholder. There is a long tradition of using mud and clay to heal skin problems. The mud from the Dead Sea in Israel is reputed to have therapeutic effects for diseases like psoriasis.
People travel there from all over the world for the mud baths.
In 1999, another Italian study reported that the unlikely combination of mud packs and antidepressants helped fibromyalgia patients both physiologically and psychologically. And in Israel, medical researchers at Ben-Gurion University found that rheumatoid arthritis patients who were treated with daily mud packs, daily hot sulphur baths, and a combination of the two, improved significantly compared to those who didn't receive any of these treatments. I do have a caveat to offer on the subject of mud baths. I once took a mud bath at a spa in Calistoga, California , and noticed that quite a number of people got in and out of the mud before it was changed. You could pick up a skin disease this way.
