Not content with slowing down and enjoying her retirement, an elderly woman has set up her own business where she charges people for her to lick their eyeballs.

Hava Celebic, also known as Nana Hava, lives in rural Bosnia and Herzegovina, claims to be the only person in the world who heals with their tongue.

The frail 80-year-old uses her tongue to remove pieces of lead, iron, coal, sawdust and glass stuck in people's eyes after sterilising her mouth with alcohol.

Patients who go to Nana Hava have to sit in a chair and raise up their eyelid while she sticks out her tongue and starts licking it 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 and says many come to her after trying conventional treatment.

She added: '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.'
