Her powers are so revered that she believes locals will cut out her tongue when she dies so they continue to harness its alleged powers.
In rural Bosnia and Herzegovina, 80-year-old, Hava Celebic or 'nana Hava' as she is known locally, claims to be the only person in the world who heals with her tongue.
The frail old woman uses her tongue to remove pieces of lead, iron, coal, sawdust and glass from eyeballs after sterilising her mouth with alcohol.
Patients will raise their eyelid for nana Hava to begin licking in search of a foreign body.
Hava said: "I learned this from a woman who was also called Hava.
"Unfortunately I can not pass this to my descendants, because my children are too disgusted to put their tongue on someone's eye."
"I've been told that people will cut out my tongue when I die so the village can continue to treat people.
Nana Hava claims to have cured over 5,000 people of many nationalities, from Americans to Russians.
Hava said: "There are a lot of those that modern medicine could not help. They came to me out of the hospital with swollen eyes, I clean them and remove the speck."
"I don't charge licking for those who are not employed and have no money but my service fee normally costs around 10 Euros."
