The Nature's Approach Celestial Indigo Herb Pack is a flexible thermal battery measuring 12 inches by 6 inches. The chassis is a dual-chambered, 100% cotton muslin envelope that allows for multi-axial flexibility. Specifications indicate it is filled with a proprietary blend of lavender, peppermint, and spearmint, along with processed grains that provide the thermal mass needed for heat retention.
The grain-based fill allows the pack to conform easily to irregular surfaces like the neck or joints. Lab data indicates that the pack maintains a therapeutic temperature for 20 to 30 minutes. It is also freezer-safe, making it a versatile tool for both heat and cold applications. However, the aromatic potency of the 12-herb blend will naturally degrade after approximately 50 thermal cycles.
- Fabric: 100% cotton muslin for higher heat resistance than synthetic minky.
- Fill: Natural herbs and grains for a weighted, conforming fit.
- Weight: Approximately 2 lbs, providing moderate weighted pressure.
Since the organic fill prevents the pack from being submerged, it should be spot cleaned only. To prevent grain-charring in high-wattage microwaves, it is helpful to heat the pack alongside a half-filled cup of water. This maintains the ambient humidity and protects the cotton fibers from becoming brittle over time.
For a similar aromatherapy experience with a different ergonomic shape, the Sharper Image Neck and Shoulder Wrap offers a lavender-infused spa blend.
