MENTHOL - pure menthol for allergy & sinus relief. FULL STEAM AHEAD - lemongrass and bergamot for an uplifting push of positive energy. DEEP SEA CALM - eucalyptus and spearmint for a purifying shower experience. CITRUS CONVOY - rosemary and sweet orange for a punch of citrus to boost the mind and spirit. SEA OF DREAMS - lavender and cedar for a calming shower experience. Directions for Use: Place in an indirect stream of water in the shower. One rock = approximately a 20 minute shower. We recommend breaking the rock in half to use twice. Or simply push the shower steamer off the wet shower floor after benefits are felt in the shower (after 5 minutes of use, for example) and reserve the rest for next time!
