An old-fashioned treatment worth its salt?

Salt therapy, an old-fashioned treatment for respiratory illnesses and skin problems, is making a comeback.


Participants in a “soul breathing” class relaxed in the Salt Cave in Minneapolis, where some patients have found relief from allergies, flu or asthma.

The first thing you notice when you enter the Salt Cave is the floor: It crunches.

Your bare feet slide gingerly across the pebble-like floor covered with 4,000 pounds of Himalayan salt crystals. The walls around you are lined with pink and orange-hued bricks of salt. As you slide into one of the zero-gravity chairs, you hear the sound of crashing waves streaming from overhead speakers. As you relax and your breathing slows and deepens, you inhale air pumped with pharmaceutical-grade salt. After a few minutes, you touch your tongue to your lips and taste salt.

This total sensory experience is called salt therapy, a homeopathic remedy meant to help respiratory problems. The age-old alternative therapeutic remedy, sometimes called halotherapy or speleotherapy, is said to alleviate symptoms of asthma, allergies, anxiety and other ailments.

There are no U.S. clinical studies examining the effectiveness of salt therapy, but its adherents swear by it.

Lori Danielson is one of them. Danielson, who suffers from allergies, is a regular at the cave in south Minneapolis.

“I get energy and more oxygen into my body. I’ve noticed my nasal passages clear up,” said the Bloomington resident. “The biggest benefit is I know I can breathe.”

Co-owner Scott Wertkin said his Salt Cave — which opened a year ago in a former chiropractor’s office — is one of only 30 or 40 businesses nationwide offering this treatment. Other centers have opened in New York, Florida, California and Chicago in recent years.

New life for old practice

Although new here, salt therapy’s use in modern history dates back to 19th-century Poland.

In 1843, a physician named Dr. Feliks Boczkowski noticed that workers at a salt mine, unlike other miners, did not have respiratory or lung problems. He attributed their healthy lungs to the air climate inside the salt mine. Salt is known to have anti-bacterial and anti-inflammatory properties. Soon, spas opened in the salt caves and today the therapy is popular in Eastern Europe, Russia and Canada.

Wertkin became interested in salt caves when he and his wife were researching remedies for their son, Jack, now 13, who has asthma. They visited a salt room in Florida and were amazed at the difference it made for their son. They decided to open their own business after learning that Chicago was the closest city with a comparable salt room.

They sought to emulate the look of a real salt mine by transforming the chiropractor’s exam room into an otherworldly space.

Wertkin constructed the cave out of 12,000 pounds of rock salt shipped from a mine in Pakistan on the edge of the Himalayas. (The most popular salts used in salt therapy are Himalayan and Dead Sea salts.)

Wertkin compares the salt room’s effect on customers’ nasal passages to “a dry Neti pot.” He said more than 3,000 people have visited the Salt Cave, located in a tiny strip mall next to a yoga studio.

Does it work?

Doctors remain skeptical about the health benefits of inhaling dry salt particles.

“There is no science behind it,” said Dr. Scott Davies, a pulmonologist at Hennepin County Medical Center.

Ingesting salt does have therapeutic properties. A 2006 study in the New England Journal of Medicine found that saline therapy was an effective and safe supplemental treatment for patients with cystic fibrosis.
