"It's something that I'm very excited about," said dermatologist Dr. Scott Sheftel.

Sheftel has been testing the Procellera, a newly approved bioelectric wound bandage.

"It has an effect of stimulating the wound, not only optimizing the environment but getting cells to migrate across the open areas," said Sheftel.

When moistened, the zinc and silver elements in the bandage create bioelectric activity -- an electric current that heals.

"The results speak for themselves. I think that the patients are the biggest advocates of the product," said Sheftel.

Flory Bourne is one of Sheftel's patients; she's battled skin cancer on her legs for years.

"When you're young, you heal fast; when you get older, you heal slow," said Bourne.

After using the bandage at home, Bourne's legs were healing after just three weeks.

"I'm grateful for the help, I'm grateful for the patch and the rest. I'm healthy," said Bourne.

Ruth Wheeler was in the same situation. She had a deep cut that wouldn't heal.

"Six weeks, it wasn't healing; within two days, it started to heal and in less than four weeks it was healed, totally healed,” said Wheeler.

The bandage works on many hard-to-heal wounds, including diabetic ulcers and shingles.

"The patients just are agonizing in pain and we've used this dressing and really have given them some relief," said Sheftel.

It's relief that has been a long time coming. Currently the bandage is only available through doctors' offices. Its makers hope to gain Food and Drug Administration approval for over-the-counter use within the next year.
