A range of salts said to have been collected from human tears has gone on sale in London. Hoxton Street Monster Supplies says the salts come from crying humans experiencing a range of emotions. The £7 range includes salts harvested from tears of sorrow, tears shed while sneezing, tears shed while chopping onions, tears of laughter, and tears of anger. A spokesman for the company said that each salt had a distinctly different flavour. "Salt Made From Tears combines centuries-old craft with the freshest human tears which are gently boiled, released into shallow crystallisation tanks, then harvested by hand and finally rinsed in brine," he said.
