These can be made by steeping a heaping teaspoon of the herb in a cup of boiling water, straining after 5 minutes and cooling. Also soothing is the juice of raw cucumbers or 1 drop of olive oil, castor oil or cod-liver oil for dry eyes placed directly in the eye. Milk with an herbal infusion in it could also be used. To administer eye drops you can either use a small dropper or dip your clean forefinger into the solution and let it drip off your finger into the animal's eye. Also, soaking a cotton ball or bit of paper towel with the remedy and letting it drip into their eye can be done.
Herbs can be helpful when used internally as well.
Adding parsley and dill to the diet can help with maintaining good eye conditions. Also, euphrasia officinalis can be used internally. It can be given as an infusion by steeping teaspoon of the herb in 1 cup of boiling water. Strain and cool. The same dosages as for the euphrasia infusion would apply.
