BodySense products combine the benefits of moist heat and aromatherapy. All BodySense products contain herbs, spices, and rice. Warm the product up in the microwave and the rice will expand and release its moisture. When the product touches the skin there is a dermal absorption of these herbs and spices. Because of this we have 8 different formulas or combinations of herbs and spices. We offer 25 different product items ranging from NeckEase, Eye Pillow, Sinus Pillow, FootEase, etc.
