I don't have cold like simptoms any more.
For a few years - running nose - no more!
This one alone is very good point to try neti. You can start with salted water. It is a good wash.
Shivambu neti is not only wash, but reinforcement of nasal mucos. And it takes only 1/4 of cup to get it done. Also one has to keep doing it forever to keep all benefits. I'd say it is good to fight infection (can be done a few times a day with fresh portions), but for maintenance one should do it at least every second day.
When I see stuff coming out - I have a push to keep going. It is a big surprise to see what is getting out of a "healthy" nose.
