Moxibustion has been used throughout Asia for thousands of years.  It was discovered by ancient people when they sat around a fire with Moxa in it.  They found the the heat from such a fire not only kept them warm but also helped helped relieve their physical pains.  Later they started to use the moxa leaves themselves for the same purposes.  Moxa is extracted from natural dried Chinese mugwort (Artemisia argyl) This sitting pad helps to reduce tension and muscle pain.
