I had this feeling to - got to think that some antibodies of mine were pulling the candida threads out of my eyes.
Yes, medlar will definitely help (along with cod liver oil). By all means go to this Korean store. If they do not know what you are talking about, tell them you want tea for your eyes, if they still do not know (I really dount it though- if they carry it they will know that this is an eye treatment). Still if they dont, just have look at their tea. Medlar looks like a one
cm long reddish dried berry. It is more like red wine color with a tone of orange in it.
Hope you find it!
