If the benedryl isn't working (and do NOT feel bad about that, there is NO herbal anything that works like benedryl does), take her to the ER or a walk-in place. Swollen eyes like that signal a bad reaction and she probably needs a dose of steroids to help. Remember, anyone at any time can react to anything. I have seen the weirdest allergic reactions in my almost 19 years as a mom, even to things the child never reacted to before or since, and I don't mess with severe reactions like you daughter's. Time to take her to see someone. I hope she feels better soon.
