Hi, I have a few friends who suffered from PND. I suggested to them that they try nasal washes using grey salt to make up the saline. In each case they claimed this helped. If it didn't take it away entirely, I put them onto serrapeptase which really did the trick for two of them the otehrs haven't yet come back to me on the matter.
There is a tool which can be used for these nasal washes but I can't remember what it's called. I could find out, if you are interested.
I use the serrapeptase for controlling my asthma and for healing (particularly broken bones,). It digests dead tissue ergo b lod clots scarring even tooth decay. I don't hvae the PND problem so I cannot comment personaly on that merely on what was reported to me by the aforementioned friends.
If you want to contact me regarding further information please feel free to ask and I'll try to help. My e-mail address (hope it's permitted to include it but surely a moderator will remove it if it's not,) is: supernanna.calem@googlemail.com
There are a few other natural remedies, which might and probably will help.
