Vitamin C and chamomile both have natural anti-histamine/anti-inflammatory properties. Increasing your vitamin C intake and maybe having a drink of chamomile tea before bed will help with the itchiness. Dark green vegetables, like spinach, would also be a good food item to increase to provide the health for your eyes. Spinach contains the lucetin for eye health, the beta carotene for immune health, and fiber for good digestive health which promotes good immune health. The fiber will also aide in flushing candida yeast from the body. If you are in the U.S., you should take a trip to your local Whole Foods market and search out their natural skin products specifically formulated for the eye area.
