Seeing as how we might actually have a summer, I thought I'd pass this tip on.
Being fair skinned, I sunburn easily. A few years ago I discovered, quite by chance, that cucumber juice is an extremely effective treatment; both soothing and healing.
Cut a chunk off the end of a cuke, score the cut face with a knife, squeeze gently to break the cells, and gently dab the juice onto the affected area. I don't know if this is an established herbal remedy, but it's at least as effective as Calamine lotion, and 100% less messy.
Enjoy
