A neti pot has CURED my asthma attacks. Make sure you know how to properly use the device or it won't be effective. I wasn't able to breathe out of my nose, I was a HEAVY mouth breather. After using this, immediately I could breathe better and now I'm breathing through my nose.
I also did a mouthwash with warm water and salt, there may be a link with oral hygeine and asthma. Using a peppermint toothpaste also helps open passages.
