Relieve Bath Bombs are intelligently designed with a blend of nine essential oils (including rosemary, tea tree, and eucalyptus essential oils) and cannabinoids to provide effective, proven relief for sore muscles, achy joints, and body tension. TLDR; We’re so much more than those $5 artificial-fragrance-filled bath bombs. We’re rooted in science. Cannabinoids provide topical relief for sore muscles and achy bones by interacting with your body’s cannabinoid receptors. These receptors help regulate inflammation, pain, and stress levels.
