Loosen Tight Neck Muscles Kozi?s Neck Wrap offers thermopeutic comfort by using temperature to activate the healing qualities of herbs and grains. Once a Kozi Wrap is heated or chilled, it?s ready to apply to aches and pains. Heat therapy provides comfort and relaxes stiff muscles. Cold therapy eases swelling and discomfort. While you?re enjoying warmth or coolness, a physician-formulated blend of herbs envelops your senses to uplift. Flax seeds add weight and help the herbal wrap contour to the shoulder and neck area, applying pressure and allowing the heat or cold to penetrate. Warm your Kozi Neck Wrap in the microwave or chill it in the freezer. Make sure you have one at home and one in your office desk drawer. Fabric: Chenille Filling: flaxseed, lavender, chamomile, lemongrass, mint, rosemary, cinnamon, hops
