Shamsher had tried medicine doled out by doctors back home but felt little relief and struggled to walk far without becoming breathless, so relatives in Pakistan suggested he visit the Khewra Mines.

"Now I can run and even play soccer just after spending three days in the mine," said Shamsher, who says he feels 60 percent better after the treatment.

The mine, located 160 kilometres (100 miles) south of Pakistan's capital Islamabad, was discovered in 320 BC by Alexander's troops and first developed by British colonial rulers in 1872, mine officials say.

Located deep underground in the mine, the asthma clinic resembles an upmarket guesthouse, with 12 beds covered in white sheets and red blankets in six independent cabins separated with salt bricks and softly lit by lamps.

There is a reception area decorated with salt lamps and a lounge complete with a fountain, sofas and a television set.

The walls and roof of the clinic are made from pure salt and a fan helps maintain the temperature and humidity, creating the so-called "micro-climate" that offers patients relief, Shah says.

A 10-day course at the Khewra Mines salt therapy centre costs 5,300 rupees (62 dollars), with 11 hours a day spent in the caves while nights are spent in a nearby hospital.

Since opening in 2007, the clinic has treated about 500 patients. Shah claims that 60 percent of patients experience some relief from their symptoms and says patients have come from as far as Britain and Saudi Arabia.

But Shahid Abbas, a doctor who runs the private Allergy and Asthma Centre in Islamabad, told AFP that although an asthma or allergy sufferer may get temporary relief, there is no quick-fix cure.

"There is no scientific proof that a person can permanently get rid of asthma by breathing in a salt mine or in a particular environment," he said.

Khaled Sajjad Khokhar, managing director of the Pakistan Mineral Development Corporation, a government body which owns the mine, says they will assess the success of the Khewra clinic before approving its expansion to 100 beds.

But some patients are returning, happy to get even temporary relief.

"This hospital is a blessing, it gave me a second life. I never had problems breathing after spending 10 days over there in 2007," said Pakistani patient Adnan Khan, on his second visit to the clinic.
