Packed with menthol crystals and Eucalyptus  essential oil for sinus relief.  These 80g tablets can be used multiple times depending on length of time in the shower.  Just wet the steamer and place it on the floor of your shower, but not in full force of the spray or it will dissolve too quickly.  The scent will rise with the steam of the shower.These are not bath bombs and should only be used in the shower because of the strong oils and menthol.
