The eyes get full of toxins when the kidneys are overwhelmed, which they tend to do after a liver flush, especially if you used Epsom Salts . It's mainly the inside of the eyes that are ocnnected to the liver, while tears/swelling are all about blood wastes, which is both liver and kidneys, mainly kidneys.
