Just did a little bit of research but apparently there are tea bags for the bath.
A little info from the site
Teas: Green tea has antioxidants that are excellent as a tonic for the skin. Black tea is soothing for the skin and actually binds broken skin cells. An excellent natural remedy for a sunburn is to brew a couple of cups of strong black tea and add it to a bath because of black tea's ability to heal damaged skin. Teas can be used to enhance other bath blends.
