It’s good for all kinds of things that affect your muscles, bones, and tendons (the tissues that connect your muscles to your bones), like arthritis, back pain, and joint pain.

The ideal temperature is between 92 and 100 F.
It’s been used for thousands of years in Asian medicine to treat stomachaches, diarrhea, and nausea, and studies show that it works for nausea and vomiting.

Some people get tummy trouble, heartburn, diarrhea, and gas because of it, and it may affect how some medications work. So talk to your doctor, and use it with care.
