well i use local honey anyway and euphraisia is a part of the homoeopathic remedy i take for my hayfever. it's good if itchy eyes is one of your problems. personally i say best to see a trained homoeopathy, imho.
here is what to do for itchy, stinging eyes 5029; make up some aspirin water, bathe your eyes in that. Strength? you choose, but i got it first time with 1 junior apirin in an eyebath of water. No eyebath? use an eggcup. fab relief.
