The Essence of Nature® Warm Patch absorbs sweat together with body wastes while you sleep, so it may make you feel more lively and refreshed the next morning.
Especially, you can feel slight warmth at the-patch-attached body part because of the warming effect of The Essence of Nature® Warm Patch.
We recommend The Essence of Nature® Warm Patch to those who have been suffering from constitutional cold hands and feet.
