Here is a recipe that takes the bite out of a mild sun burn.
To make enough for 1 bath
4 tea bags
16 tablespoons dried mint (double if fresh)
1 pint 12 floz/910ml water
Place all the ingredients in a medium-size saucepan and bring to the boil over a high heat. Reduce the heat to low and simmer for 5 minutes. Remove from the heat and leave the mint to infuse for 15 minutes. To use, strain the liquid into a jar, discarding the tea and mint leaves, and allow it to cool. Dab the mixture onto sunburned areas with cotton balls or a washcloth. Or pour the liquid into warm bath water; you can also add the tea from the bags and the mint tied in a piece of cheesecloth and dropped into the bath. Soak in the mixture for 10-15 minutes. Repeat as necessary.
Caution For severe burns with blistering or crusting, consult your doctor.
