Raylieve™ Pain Stick delivers two distinct timelines simultaneously. The cooling you reach for in the moment. The FIR engine that keeps working long after. The Cooling You Reach For Pharmaceutical-grade menthol activates TRPM8 cold receptors within seconds. Layered with methyl salicylate from wintergreen oil for deeper salicylate analgesia, arnica's sesquiterpene lactones for direct anti-inflammatory action, ginger's gingerols for a warming counterpoint, and rosemary's penetration-enhancing terpenes to drive everything deeper. The Engine That Stays After the menthol and salicylate volatilize, the FIR mineral matrix remains deposited on the skin. It absorbs your body's thermal radiation and re-emits it as far-infrared photons peaked near 9.4 µm — tuned to the vibrational absorption modes of your body's water. Powered entirely by you.
