Shower tablets commonly list sodium carbonate as the primary active ingredient, while the bath crystal products list sodium chloride.
The vapors are described as a proprietary blend that includes eucalyptus and other essential oils, with menthol and camphor aromas noted.
Place a tablet on the shower floor just before you step in and run warm water to produce steam. The tablet will dissolve and release non‑medicated vapors as the steam forms; inhale the vapors during your shower.
Sprinkle about two handfuls (roughly 1/3 cup) of crystals under warm running water, fill the tub at least halfway, allow the salt to dissolve, and soak for up to 20 minutes.
Packaging generally indicates adult use only, advises consulting a doctor if pregnant or nursing, and warns to keep the product out of reach of children.
