But that is what Maria Blasi and her son Andrew Blasi feel they have done for Pasquale Tassoni who had difficulty even breathing three years ago.

While they don't claim to have a cure, Mr Tassoni had been in hospital and was told there was nothing more that could be done.

Mr Tassoni's lung capacity was so low he could hardly walk more than a couple of metres.

But his life changed after his daughter saw a story on A Current Affair about salt therapy.

Mrs Blasi originally thought "what a load of rubbish" but as an only child was willing to do whatever it took to help her father.

"But my husband [Joe Blasi] said stop being such a pessimist. I Googled the number and took him up. The rest is history."

The family was so concerned about Mr Tassoni making that first trip they bought a portable oxygen machine for the journey.

But during that first 40 minute therapy he took off the machine and put it on the table and had a what they described as a beautiful pink colour in his face.

It was the first time they had seen that in years.

"He wore his oxygen mask all the way up but when we drove home from Bondi he didn't wear it at all until we got to Bulli Tops and I asked him to put it on just to be safe," she said.

"I thought 'This is just amazing. It is a miracle'.

He now only has to travel to Fairy Meadow for treatments, because his grandson Andrew invested his savings in opening Illawarra Salt Therapy.

"He [Mr Tassoni] comes now generally once a fortnight but he can go three weeks without a treatment because he is that much better," Mrs Blasi said.

"He is back to his normal self and we are talking about a man who struggled to feed himself or dress himself. He could not move, he was literally chair bound. He is not cured, his lungs are still damaged but he is having a better quality of life."

Illawarra Salt Therapy has a room seven people can use, a children's room and a smaller room designed for people with chronic conditions that would prefer to be on their own or only with a few people.

"We can see up to 12 patients in an hour if need be," Mrs Blasi said.

"A generator starts and the room fogs up with a thick blanket of fog and it is a dry salt. It is a dry steam. There is no water involved.

"It dries up the infection, it dries up the phlegm and it helps clear you up if you have got sinus, or if your airways are blocked it opens them up.

"It is just brilliant. People are getting fantastic results. We have almost got 900 patients."

Not only is the clinic attracting hundreds of people from the local area but many are coming from places such as Goulburn, Campbelltown and the Far South Coast.

And Mrs Blasi expects that to grow as more people find out about it.

"We don't claim to cure anything but if we can give people a better quality of life," she said.

"Dad was struggling for every breath before. It was so bad you almost wanted to breath for him."
