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 that the heat from such a fire not only kept them warm but also 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 neck pillow helps to reduce tension, muscle pain, stiff neck, and headaches. The buckwheat hulls allow constant air circulation through the pillow, which helps keep you cool and dry. 

(These pillows contain small pieces of buckwheat and should be kept out of reach of children under 8 years of age.)
