I use a Neti Pot with the pre-prepared salt packets sold at pharmacies. The first time I used it, well, let's just say I was shocked. I was literally "plugged" up in my nostrils and the "plugs" came out. I also found out I have a deviated septum - something that seems to run in my family - but I had no idea I had. The fluids will only run one way, through the right nostril to the left, but not the opposite way.
I definitely can breathe better. Someone I know who had cancer had been told by her cancer treatment team to use a Neti Pot to reduce the chances of getting sick. Using one has sold me on the value of the salt treatment. Using the aerosol saline spray doesn't touch the results of this process.
I started using a neti pot for seasonal allergies and this definitely works for me. For the person with the deviated septum I would suggest surgery. I had the same thing so while I had a rhinoplasty my wonderful surgeon corrected the deviated septum at the same time. When I do suffer from a head cold now at least I am not so stuffed up and able to breathe. I highly recommend doing this.
As a nurse/holistic practioner we mixed all the inhalant meds in saline. So makes sense to me. Acupuncture is a wonderful treatment for allergies. As always make sure they are a qualified practioner.
