When my kid had an infection in his eye I used the teabag poultice of chamomille. It was a great solution! I used it several times a day for a really short time on his eye. Did not really attach it with fabric but just held it in place with my hand for a little while.
Looking forward to my next hike to try the Plantain poultice and also use the Mugwort in my shoe for this!
