A surprising remedy

I accidentally discovered that moistening mosquito stung parts of skin with salted water relieves the intolerable itching. After having my legs nearly perforated by mosquitoes in the garden I felt an almost immediate soothing after taking a bath with aromatic salts. Another time I tried simple kitchen salt with water and it worked just as well. I have no idea what chemical reaction goes on in the process, but as long as it works it's fine by me.
